Metal lath suspensions arecommonly made belowvirtually all types of construction for fire-ratedand non fire-rated plasterceilings. Framing of 1 1/2"C.R. channels are spacedup to 4' o.c. perpendicularto joists and are cross-furred with 3/4" C.R. channels spaced accordingto specifications for typesand weight of metal lath.Lath is then properlylapped at sides and endsand tied every 6" to the 3/4" channel.

Where it is advisable to installunrestrained ceilings, having perimeters separated from adjacentwalls or partitions, galvanized casing beads

should be installed aroundthe periphery.

Metal Lath is frequently usedfor furred as well as suspended ceilings.

Metal lath is used for furringfrom wood, concrete andsteel joists.

RECOMMENDATIONS1. Control joints should be

installed in ceilings withoutperimeter relief with a max-imum distance betweensuch joints of 30' with amaximum undivided areaof 900 sq. ft. With perime-ter relief, maximum dis-tance is 50' with maximumundivided area of 2500sq.ft.

2. Use three-coat plastering onmetal lath.

National testing organizations frequently participate in themany product tests conducted at NGC Testing Services. Fire,acoustical, structural and analytical test laboratories areavailable commercially through NGC Testing ServicesSM forother manufacturers and research interests. For information,call 716-873-9750 or www.NGCTestingServices.com.

YOUR TECHNICALRESOURCEToday, more than ever, clear,

accurate information is vitalto every construction job.The challenges of construc-tion continue to grow:increasingly innovativebuilding designs, tighterbudgets, tighter schedules,and the continuing devel-opment of new materialsand construction tech-niques.

A NETWORK OFTECHNICAL SUPPORTIn keeping with the corporate

mission to become the pre-ferred supplier for our cus-tomers, National Gypsumhas made a total commit-ment to technical assis-tance and created a net-work of support to providevaluable assistance at everystage of a project’s devel-opment.

Field Representation. Beforeconstruction begins, whileplans and specifications arebeing produced, theseexperienced, trained pro-fessionals provide technical consultation in selecting, specifying and using gypsum-based building materials.During the constructionphase, our FieldRepresentatives have theexperience and the trainingto assure that the National

Gypsum products you needand specify are right for the job. They are backedup by thoroughly trainedCustomer ServiceRepresentatives who canalso help with productselection and purchase.

Continuing Research. Becausethe building industry andbuilding codes are con-stantly changing, NationalGypsum maintains a full-scale research center thatcontinually tests and evalu-ates products, applications,construction systems andtechniques.

Immediate Answers. Ofcourse, there are timeswhen you need an answerto a pressing situation orquestion. For this reason,National Gypsum has setup our TechnicalAssistance Hotline: 1-800-NATIONAL (1-800-628-4662).

One toll-free phone call givesa direct, personal link to atechnical expert with up-to-date knowledge of specifi-cations, building codes,product information andmuch more.

QUALITY IS SYSTEMATICAt the National Gypsum

Research Center, we concentrate not only onbuilding products individu-ally but also on completeconstruction systems. In

such systems, prod-ucts are evaluatedtogether as com-plete buildingassemblies – walls,partitions, floorsand ceilings.

Before NationalGypsum releases asystem to the build-ing industry, the sys-tem is thoroughlytested and theresults are correlatedand charted, makingit easier for thebuilder or architectto match a system tohis needs or tobuilding codes. Thisextensive databaseof technical infor-mation is madeavailable to you notonly through techni-cal bulletins such asthis one, but alsothrough our techni-cal support network.

The construction systemsreferred to in this manualare designed and testedwith material manufactured by National Gypsum.Substitutions of other products or brands forNational Gypsum Productsare not recommended.

Field Installation of tested sys-tems must be identical tothe laboratory installationto produce optimum per-formance of these systems,though duplication of con-trolled, laboratory resultsin such field installations isnot guaranteed.

Performance tests are conducted according toaccepted national stan-dards under controlled lab-oratory conditions to mini-mize variances and to per-mit comparison of testresults of all types of sys-tems, similar and dissimilar.

Detailed recommendationsare contained in each sec-tion. Architects, structuralengineers or others whoare responsible for fieldinstallations must maketheir own determinationsconcerning the applicabili-ty of the laboratory perfor-mance test results to thedesign or construction ofany specific structure.

National Gypsum’s Technology Innovation Center is located inCharlotte, North Carolina. National Gypsum has always held a leader-ship role in the development of gypsum based products and systems.Many of today’s most innovative gypsum, joint treatment and cementboard products and systems were developed, tested and introduced byNational Gypsum Company.

8 NATIONAL GYPSUM SOUND AND FIRE RATED ASSEMBLIES

Sound and Fire Rated Assemblies

SOUND RATINGSDrywall and plaster construc-

tion systems are laboratorytested to establish theirsound insulation character-istics. Airborne sound insu-lation is reported as theSound Transmission Class(STC), whereas impactnoise, tested on floor-ceil-ing systems only, is report-ed as the Impact InsulationClass (IIC).

When selecting systems basedon laboratory performanceratings, it should be clearlyunderstood that field condi-tions such as flankingpaths, air leaks, etc. causedby design or workmanshipcan reduce acoustical per-formance. For these rea-sons National GypsumCompany cannot guaranteethe performance ratings of specific constructionassemblies erected in the field.

To achieve maximum soundisolation from an assembly,published constructiondetails must be followedcompletely. The use ofnon-hardening, permanent,resilient, acoustical sealantis recommended to seal offair leaks at floor, ceiling,and partition or wall inter-sections.

In selecting a construction sys-tem where sound isolationis important it is necessaryto take into account thebuilding’s overall structuraldesign, openings, type ofoccupancy, location andbackground noise level.The complexity of the pro-posed system will necessar-ily affect the final cost andpossibly the in-placeacoustical performance ofthe system.

The national standard for air-borne sound testing, ASTME 90, measures the soundtransmission loss from 125to 4,000 Hertz. It is mea-sured at 16 one-thirdoctave frequencies. Thedata measured in ASTM E 90 is then fitted to theSTC curve as is specified inASTM E 413. The STCshould not be comparedwith FSTC values that areobtained from field soundtransmission loss tests fol-lowing ASTM E 336 proce-dures. The method used todetermine FSTC ratings isdifferent and cannot be

related to STC ratingsachieved by ASTM MethodE 90.

FIRE RESISTANCE The term “fire-resistance”

designates the ability of alaboratory-constructedassembly to contain a firein a carefully controlled testsetting for a specified peri-od of time. Such an assem-bly might be a partition, afloor/ceiling, a roof/ceiling,or a protected beam or col-umn. The degree thatassemblies put together andtested under controlled lab-oratory conditions retardthe spread of damagingheat is measured in inter-vals of time. For example, ifa construction assembly inthe laboratory adequatelycontains the heat for twohours and meets otherrequirements during thelaboratory fire test, it isgiven a two-hour fire resis-tance rating.

Fire tests may be conducted atany of several recognizedfacilities. Partitions,floor/ceilings, roof/ceilings,beams and columns aretested in accordance withASTM Standard E 119, FireTests of Building andConstruction Materials.Fire-resistance ratings arebased on full-scale testsunder controlled conditionsand are generally recog-nized by building codeauthorities and fire insur-ance rating bureaus.

Requirements for fire-resis-tance ratings are usuallyassigned by local buildingcode officials based on theexpected occupancy of thespace. It is critical that youreview plans in the bidstage to ensure that thedetails drawn match thereferenced design numbers.If the detail drawn does notmatch the assembly designnumber as listed in theGypsum Association FireResistance Design Manual,UL Fire ResistanceDirectory, or FactoryMututal SpecificationTested Products Guide,contact the architect for aclarification.

Fire-resistant ratings representthe results of controlledlaboratory tests on assem-blies made of specific con-

PARTITION CONTROLJOINTSIn long expanses of partitions

such as corridors, controljoints should be used atleast every 30'. Door andwindow openings createstress points in partitionsand are recommendedlocations for control joints.Where jambs extend fromfloor to ceiling and arespaced not farther apartthan 30', no control jointsare required. When“through-wall” controljoints are required in firerated assemblies, specialdetails are necessary whichare shown on page 96.They are based onWarnock-Hersey ReportWHI 651-0318.1.

CEILING CONTROL JOINTSFor large expanses of ceilings

with perimeter relief, control joints must belocated a maximum of 50'o.c. in either direction;without perimeter relief,30' o.c. maximum in eitherdirection. Control jointsshould be installed whereframing or furring changesdirection.

PERIMETER CONTROLJOINTSAcceptable perimeter control

joints in systems do notadversely affect fire orsound ratings. The use ofperimeter control joints infire-rated assemblies isdescribed in UL Report R-4024-7-8 and FactoryMutual Report 16738.69.

figuration. For that reason,National GypsumCompany cannot guaranteethe performance of specificconstruction assemblieserected in the field. Whenselecting constructionassemblies to meet certainfire-resistance require-ments, caution must beused to ensure that eachcomponent of the assemblyis the one specified in thetest. Further, precautionshould be taken that assem-bly procedure is in accor-dance with that of the test-ed assembly.

CONTROL JOINTS ANDISOLATION DETAILSThough most systems referred

to in this manual are non-load-bearing, they needstructural consideration oftheir ability to retainintegrity over a period oftime and be relatively rigid.When other elements suchas doors, fixtures, cabinets,etc., are affixed or joined toa drywall or plaster system,provision must be made toensure that these loads areadequately supported.Structural framing, com-pletely separate from thesystem, may be necessaryto support eccentric orheavy loads.

CONTROL JOINTSControl joints are frequently

necessary to prevent crack-ing in the gypsum boardand plaster systems.Isolation should always beconsidered where structuralelements such as slabs,columns, or exterior wallscan bear directly on non-load-bearing partitions.

Gypsum as well as otherbuilding products andmaterials are subject tosome form of movementinduced by changes inmoisture or temperature, orboth. To relieve the stresseswhich occur as a result ofsuch movement, controljoints are required in bothpartitions and ceilings.

Control joints preventcracking in large areas ofgypsum board.

DESCRIPTION TECHNICAL DATA

JUMBO GYPSUM SHEATHING

SQUARE EDGES FOR VERTICAL APPLICATION

WAX-TREATED GYPSUM CORE

WATER-REPELLENTPAPER SURFACE

Illustration colors for visualization purposes only.

Gold Bond Brand GypsumSheathing is a waterresistant board productdesigned for attachment tothe outside of exterior wallframing as a water resistantunderlayment for variousexterior siding materials.The sheathing ismanufactured with atreated water resistant corefaced with water repellentpaper on both face andback surfaces and on bothlong edges. Fire-Shield(type X) Jumbo Sheathinghas special additives in thecore to enhance its fireresistive properties.

USES1. As a sheathing for wood

framed residentialconstruction to provide fireresistance, weatherprotection and to add tostructural strength whenused under exterior finishessuch as vinyl siding,clapboard, paneling,masonry veneer, stuccoand shingles.

2. As a sheathing for steel studcommercial construction

and as a component incurtainwall systems andexterior insulation systemsand finishes.

3. As a sheathing for use infire-rated exterior wallassemblies.

ADVANTAGES1. Economical: Both material

and application costs arelow.

2. Fire Resistance: The non-combustible gypsum core of the sheathing helpsprotect framing elementseven when the siding orfinish material iscombustible.

3. Weather Protection:Gypsum Sheathing’smoisture resistant core andwater repellent surfacesprovide a barrier thatresists passage of wind andwater.**

4. Little or No Sawing:Gypsum Sheathing can bescored and snapped toexact size without cuttingor sawing.

SIZES AND TYPES1/2" x 4' x 8', 9', 10' (Jumbo) square edge.5/8" x 4' x 8', 9', 10' (Fire-Shield Jumbo) square edge.VAPOR PERMEABLEGypsum Sheathing typically has an average vapor permeance

of 20 perms (dry cup method) which allows the escape ofnormal interior created water vapor.

SURFACE BURNING CHARACTERISTICS:(FIRE HAZARD CLASSIFICATION)Gypsum Sheathing has a flame spread of 20 when tested under

ASTM E 84. Source: Factory Mutual Report No. 16738.102.FIRE-RESISTANCE RATINGSA one-hour fire rating can be achieved for a wood framed wall

when constructed per UL Design U305 consisting of nominal2 x 4 wood studs 16” o.c. faced on the outside with 5/8" Fire-Shield Gypsum Sheathing and on the inside with 5/8" Fire-Shield Gypsum Board.

A two-hour fire rating may be obtained per UL Design U371with 2 x 4 wood studs 16" o.c. with two layers of 5/8" Fire-Shield Gypsum Board applied to the interior side and 5/8" Fire-Shield Gypsum Sheathing, faced with brick veneer on theexterior side.

One and two hour fire ratings may be obtained for a steel framedwall when constructed per UL Designs U 418 and U 425.

STRUCTURALRacking tests have been conducted for the Gypsum Association

by an independent laboratory according to ASTM E 72.Average ultimate racking load values were as follows:

Studs spaced 16" o.c., fasteners galvanized 11 gauge nails 7/16"head, 1 1/2" long for 1/2" sheathing and 1 3/4" long for 5/8",7" o.c. in the field and 4" o.c. on edges and ends for 5/8"Gypsum Sheathing; 8" o.c. in field and 4" o.c. on edges andends for 1/2" Gypsum Sheathing.

Corner Bracing – Where continuous diagonal bracing isrequired, many building codes allow the use of 4' wideboards of 1/2" Gypsum Sheathing applied vertically to be usedin place of 1" by 4" wood let-in bracing.

Shear Walls – Where wind or seismic forces require shear wallsto resist these lateral forces, most building codes provideallowable shear values for walls having gypsum sheathingapplied vertically to wood framing. Specific values withconstruction requirements and limitations are contained in themajor model building codes (International Building Code,National Building Code, Standard Building Code and UniformBuilding Code).

Shear values for all gypsum board, including Gypsum Sheathing,are defined in GA-229 at www.gypsum.org/GA-229-08.pdf.

SPECIFICATION COMPLIANCEGold Bond Gypsum Sheathing is manufactured to comply with

ASTM Specification C 1396.

DESCRIPTION

GOLD BOND® BRAND

e2XP™ EXTENDED EXPOSURE SHEATHING

e2XP Sheathing is a moistureand mold resistantsheathing panel designedfor attachment to theoutside of sidewall andsoffit framing as a waterresistant underlayment forvarious exterior materials.e2XP Sheathing ismanufactured with anenhanced moisture andmold resistant core andfacer. The facer iscomposed of a coatedfiberglass mat whichprovides superior weatherresistance capabilities. It isproduced in 1/2" and 5/8"thicknesses, 4' wide in 8',9' and 10' lengths. e2XPSheathing is lightweight,scores and cuts easily andis specially coated on thefront, back and sides foreasy handling.

BASIC USESe2XP Sheathing can be used

in both wood and metalstud construction toprovide fire resistance,weather protection and toadd to structural strength.e2XP Sheathing can beused as a substrate forvarious air and waterresistive barriers includingbuilding wraps, self-adhesive membranes andliquid applied coatings. Itcan be used as acomponent in curtainwallor Exterior Insulated FinishSystems (EIFS), and undervarious exterior finishessuch as metal, vinyl, woodor fiber-cement siding;brick/stone veneer, orconventional stucco. The5/8" e2XP Fire-Shield®

Type X gypsum panel canbe utilized for exterior fire-rated wall and soffitassemblies.

ADVANTAGES• Manufactured to meet

ASTM C 1177 (“StandardSpecification for Glass MatGypsum Substrate for Useas Sheathing”).

• Will withstand up to 12months of exposure totypical weather conditions,subject to terms, conditionsand exclusions of NationalGypsum’s LimitedWarranties.

• Treated fiberglass face,back and gypsum coreprovides extra protectionagainst mold growth perASTM D3273.

• Superior water resistancewhich does not impedevapor transmission.

TECHNICAL DATA

Gold Bond BRAND Two-WayHardwall Plaster is abasecoat plaster whichrequires the job siteaddition of an aggregateand water to provideworking qualities and isdesigned for interior useover all accepted plasterbases. It may be applied byhand or used throughpump/spray plasteringmachines.

ADVANTAGESControlled UniformityTwo-Way Hardwall Plaster is

set-stabilized and adjustedfor market requirementsand seasonal changes.When mixed with sand orother aggregate it hasuniform working qualitiesand excellent spread.

StrengthTwo-Way Hardwall Plaster

properly proportioned withaggregate forms a hard,durable base for the finishcoat. Its high tensile andcompressive strength resultsin increased resistance tominor structuralmovements, impacts andabrasions.

Fire ResistanceTwo-Way Hardwall Plaster is

essentially mineral incomposition and will notsupport combustion.

Specification Reference ASTM Designation C 28,

“Gypsum Plasters”.Bag Weight 100 lbs. (45.4 kg)

Gold Bond BRAND Gypsolite is a lightweight gypsumbasecoat plaster mixed atthe mill with correctly sizedand proportioned perliteaggregate, requiring onlythe addition of water on thejob. It is manufactured tobe trowel-applied overgypsum or metal lath.

ADVANTAGESUniform Strength andHardnessUniformity is ensured through

exact proportioning andthorough mixing of gradedperlite and gypsum plasterat the mill. Gypsoliteprovides a uniform base forthe finish coat.

LightweightGypsolite weighs less than

half as much as sandedgypsum plaster, thusreducing the dead-load onframing.

High Insulating ValueGypsolite has a “k” factor of

1.5 which provides about 3 1/2 times the insulatingvalue of sanded plaster.

LIMITATIONSWhen used over metal lath, a

sand float finish should bespecified. A smooth-trowelfinish is not recommendedsince the combination of arelatively soft (perliteaggregated) basecoat and ahard (smooth-trowellime/gauging) finish has thepotential for cracking andspalling of the finish coat.

Fire ResistanceGypsolite has excellent fire-

resistive qualities andgenerally provides fireratings higher than sandedplaster.

Gold Bond BRAND Gauging Plaster, quick set or slow set type, isdesigned for use with finish lime. It is specially ground,calcined gypsum, which readily mixes with water and limeputty. Proper proportioning is essential, since gauging addsstrength and hardness to the finish surface by reinforcing theplastic non-setting lime against shrinkage and cracking. Afinish coat of gypsum gauging plaster and finish lime, jobmixed 2 parts hydrated lime to 1 part plaster by weight, isdesigned primarily for interior smooth trowel application overa gypsum plaster basecoat. Smooth finish plasters should beapplied at a thickness of not more than 1/16". Texture finishesshould be applied at a thickness of not more than 1/8".

Complies with ASTM Designation C 28.Bag WeightQuick Set – 100 lbs. (45.4 kg) (50 lb. (22.7 kg) bags available in

Gold Bond BRAND Moulding Plaster is a very white, finely ground gypsum, primarily used for all kinds of ornamental plaster work.Because of its low expansion, excellent strength and hardness, it is specially adaptable for casting in rubber, gelatin and othertypes of moulds. For casting purposes, only water is added. Forrun-in-place ornamental work, such as cornices, the mouldingplaster is used with lime putty, mixed 2 parts lime to 1 partmoulding plaster by weight.

PAINTING PLASTERVarious job conditions such as suction differences, wet or only

partially dry walls, and reactions between paint and lime havecaused unsatisfactory paint finishes, particularly on new construction.

Alkali-resistant primers specifically formulated for use over newplaster will permit decorating with oil or latex type paints.

Quality paint products should be used and manufacturers’recommendations followed. Finished plaster should bepainted or covered to conceal possible discoloration. Thepaint system should be suitable for use over plaster surfacesthat contain lime, which has a high pH of 10-13.

It is essential that plaster be sound and completely dry beforepainting. Conventional plaster may require 30 to 60 days tofully dry.

Gypsum plaster, mixed with sand or lightweight aggregate, isapplied over a metal lath base providing an economical fireprotective covering for structural steel columns.

ADVANTAGESLightweightThis system of fireproofing weighs only half as much as tile and

one quarter as much as standard concrete for equivalent fireresistive ratings. This means a reduction of up to 1/3 in dead-load weight, reducing the size and cost of footings,foundations and structural framing.

Fire ResistanceFire resistance ratings up to four hours can be obtained.EconomyLath is low in cost, quick and easy to apply, thereby effecting

savings in material and labor costs.LIMITATIONSIn warehouses or other occupancies where columns might be

damaged, angle iron guards are recommended to protectcolumn corners to the necessary height.

Metal lath suspensions arecommonly made belowvirtually all types of construction for fire-ratedand non fire-rated plasterceilings. Framing of 1 1/2"C.R. channels are spacedup to 4' o.c. perpendicularto joists and are cross-furred with 3/4" C.R. channels spaced accordingto specifications for typesand weight of metal lath.Lath is then properlylapped at sides and endsand tied every 6" to the 3/4" channel.

Where it is advisable to installunrestrained ceilings, having perimeters separated from adjacentwalls or partitions, galvanized casing beads

should be installed aroundthe periphery.

Metal Lath is frequently usedfor furred as well as suspended ceilings.

Metal lath is used for furringfrom wood, concrete andsteel joists.

RECOMMENDATIONS1. Control joints should be

installed in ceilings withoutperimeter relief with a max-imum distance betweensuch joints of 30' with amaximum undivided areaof 900 sq. ft. With perime-ter relief, maximum dis-tance is 50' with maximumundivided area of 2500sq.ft.

2. Use three-coat plastering onmetal lath.

(1-800-628-4662)

BASECOAT PLASTER PROCEDURESTwo-Coat WorkApply first coat with firm pressure to form good bond on the

Gypsum Plaster Base or masonry base; then immediatelydouble back (without cross-raking first coat) using material ofsame proportion to build proper basecoat thickness. Straighten to a true surface (without applying water) to receive the second (finish) coat.

Surface should be left sufficiently rough and porous to providesuitable bond of the finish coat.

Three-Coat Work“Scratch” – “brown” – finish is generally used for metal lath or

masonry bases, and is performed in discrete steps.• Scratch (first) coat: Should be applied with sufficient

material and pressure to obtain good bond over solidbases or form full keys through metal lath. Provide suitable material thickness for scratching (raking) toobtain good mechanical keying of the “brown” coat.

• Brown (second) coat: Shall be applied after the scratch(first) coat has set hard and still damp. Apply to givemass and surface as for double-back in two-coat work.

Finish Coat Plaster ProceduresGeneral Requirements (Basecoat Condition)Application over a partially dry basecoat is preferred. If basecoat

is thoroughly dry, wet with even application of water to asemi-dry condition. Avoid excess water. Do not apply finish to basecoats having free water on the surface.

Application – Gauged Lime Putty Trowel FinishSmooth Finishes

• Scratch in tightly over the basecoat, covering the surface completely, then double back immediately with material from the same gauge, filling out to a true, even surface with total thickness of not more than 1/16".

• Allow finish to “draw” (lose moisture to basecoat andambient air) and firm up – then trowel it well to compact and close the surface under the edge of thetrowel. Dash water on the surface for lubrication anddevelopment of soft material along trowel’s edge to fillsurface depressions or other blemishes.

• When finish plaster setting action is under way, a second (final) water troweling can be done with strongpressure to obtain a polished surface if desired.

Texture Finishes• Apply finish as above to a true, even surface with total

thickness not more than 1/8".• Allow finish to “draw” (lose moisture to basecoat and

ambient air). Then begin floating, texturing, or skiptroweling to achieve desired texture. Additions of clean graded silica may be required to achieve desired texture.

DryingConventional plaster systems should be allowed to dry30 days minimum under ambient conditions prior tofinal decoration. Variances in humidity or poor drying conditions may affect the drying process.

StorageGypsum plaster must be kept dry before use. Storage conditions vary with location and seasonal changes, which may affect storage life. These conditions may affect product characteristicssuch as setting time, working qualities, component separation, or lumping, etc. Such aging is normally a function of exposure to humid air, temperature, and physical support in warehousing. Adverse storageconditions or prolonged storage may affect the workingqualities of the product. Rotate inventory frequently forbest results.

VENEER PLASTER SYSTEMS

DESCRIPTION

Kal-Kore boards are screwed to steel studs or nailed orscrewed to wood studs toform a base.

Veneer plasterexpands architecturaldesign limits as withthis curved vaultedceiling.

Joints are reinforced with Kal-Mesh fiberglass webbing.Steel corner and casing beadsprotect corners.

Kal-Kote is applied in 2 coats, a base and a finish, to form a hard-surfaced, 1/8" total thickness.

Veneer Plaster Systems consistof a 4' wide gypsumplastering base with aspecial, highly absorptivepaper surface that iscovered with thinlytroweled, special purposeplasters. Two basic types of veneer plaster areavailable: Uni-Kal and X-KALibur, which are one-coat plaster systemproducts; and Kal-Kote, atwo-coat plaster system.The gypsum plaster base,Kal-Kore, is erected in thesame manner for bothsystems. Both veneerplaster systems can bespecified for virtually alltypes of partition andceiling constructionsincluding wood or steelframing or furring andmasonry. For bothresidential and commercialbuildings, either type ofveneer plaster systemproduces a wall more nail-pop resistant than drywalland, when properlyinstalled, more crackresistant than conventionallath and plaster.

ADVANTAGES - GENERALThe advantages of veneer

plaster over othercommonly used partitionand ceiling systemsinclude:

1. Rapid installation whichreduces overallconstruction time.

2. Appearance and surface ofconventional plaster atlower cost than regularplastering.

3. High resistance to cracking,nail-popping, impact andabrasion failure.

4. Mill-mixed plastercomponents help ensureuniform installationperformance and finishedjob quality.

ADVANTAGES - ONE-COATSYSTEM (UNI-KAL/X-KALIBUR)1. Requires only one plastering

material on the job.2. Slightly lower in-place cost

than two-coat system.3. Can be applied directly to

concrete block.4. X-KALibur is formulated

to have extended setcharacteristics beyondtraditional Uni-Kal settingtimes.

ADVANTAGES - TWO-COATSYSTEM (KAL-KOTE)1. Kal-Kote System may be

used for plaster-embeddedelectric radiant heatingcable systems.

2. Same applicationtechniques as forconventional plaster.

3. Greater crack resistancethan one-coat systems.

4. Can be applied directly toconcrete block.

LIMITATIONS1. Not recommended for

exterior use or wheresubject to weathering,direct water contact ortemperature exceeding125˚F (52˚C) for extendedperiods of time.

2. Framing spacing is limitedand partition heights arereduced in comparisonwith some standardconstructions.

3. Provides less rigidity thansimilar standard plastersystems.

4. When Uni-Kal/X-KALiburwill be applied, do notinstall Kal-Kore too far inadvance of plastering sinceUni-Kal/X-KALibur bondcan be adversely affected ifface of Kal-Kore hasbecome faded from light. IfKal-Kore has been faded,apply Kal-Kote Base Plasteror a bonding agent toobtain good bond.

5. All are designed for trowelapplication. Gold BondVeneer Plasters are notsuitable for conveyance orapplication byconventional plasteringmachines.

6. Compared to conventionalplasters, Veneer PlasterSystems are more subject tobeading (ridging) andcracking at the joints underrapid drying conditionssuch as those caused bylow humidity, hightemperature and/or highdraft exposure.

7. All provide a base overwhich paints or otherfinishes should be applied.

8. Do not use a polyethylenevapor retarder unlessstructure is ventilatedadequately duringapplication of veneerplasters.

9. A bonding agent must beapplied to monolithicconcrete prior toapplication of eithersystem.

10. Mix only full bags ofplaster for proper set.

11. Do not use self-adhesivemesh tape.

VENEER PLASTER FORMETAL AND WOODFRAMING1. Wood Studs or Joists.

Wood members shall meetthe minimum requirementsof local building codes.Framing shall not exceedspacing shown in Table 1on page 46. Most partitionfire ratings require that Kal-Kore be applied vertically.When such ratings are notrequired, horizontalapplication may be used tominimize joints. Forceilings, application at rightangles to framing ispreferred.

2. Metal Studs. Align floorand ceiling tracks to ensureplumb partition. Securetrack with appropriatefasteners at a maximum of24" o.c. Position studs intrack on specified centersby rotating into place for afriction fit. Secure studslocated adjacent to doorand window frames,partition intersections andcorners by self-drillingsheet metal screws throughboth flanges of studs andtracks or by use of steelstud clinching tool. ApplyKal-Kore vertically for mostfire ratings. When ratingsare not required, horizontalapplication may be used tominimize joints.

3. Masonry Wall Furring withScrew Furring Channel.Attach furring channelvertically spaced not toexceed spacing shown inTable 1 on page 44. Fasten

each channel with concretestub nails or appropriatefasteners through channelflanges into the masonry orconcrete. Fasteners shall bespaced on alternate flangesnot over 24" o.c. Apply Kal-Kore vertically orhorizontally in maximumlengths to minimize endjoints.

4. Furred Ceilings with BarJoists. Attach regular furringchannel 16" o.c. to barjoists spaced up to 4' o.c.Resilient Furring Channel(wire-tied only) shall span amaximum of 24". Wire tieFurring Channel to joists oruse 1 1/2" Drywall FurringChannel Clip for 1 1/2"carrying channel. ApplyKal-Kore with paper boundedges at right angles to thefurring channel.

KAL-KORE AND HI-ABUSE®

KAL-KORE APPLICATIONNote: Application shall

conform to ASTM C 844.1. Cut and position Kal-Kore

accurately. Bring all jointedges together but do notforce into place. Positionall end joints over framingmembers. To avoid ridging,minimize gaps betweenadjacent boards.

2. Minimize the number of end joints by usingmaximum practical lengthswith proper positioning.

3. Stagger joints so that theyoccur on different framingmembers and will not bedirectly opposite oneanother on partitions.

Avoid joining Kal-Kore atcorners of doors, windowframes, and other openings,unless control joints arecreated using E-Z StripControl Joints.

4. Fasten Kal-Kore to framingmembers with face out,using the proper type andspacing of fasteners shownunder types of fasteners.

5. Draw Kal-Kore tight toframing. Drive fastenersstraight and dimple thesurface without breakingthe paper face.

KAL-KORNER BEADAPPLICATIONInstall Kal-Korner Bead using

appropriate fastenersspaced 12" apart.

E-Z STRIP CONTROL JOINTAPPLICATIONInstall E-Z Strip Control Joint

at 30' max. spacing onwalls and 50' max. spacingin either direction onceilings. Apply the controljoint with staples spaced 6"along each side of theflanges.

TREATMENT OF KAL-KOREJOINTSPre-treat all joints and

fasteners in Kal-Kote andUni-Kal Plaster Systemswith Kal-Kote Base Plaster,Uni-Kal, X-KALibur or Sta-Smooth Joint Compound.

Low humidity, hightemperatures and rapidlycirculating air can causecracking of plaster and jointbeading when Kal-Kore is

applied to metal framing.To minimize this duringthese conditions, jointsmay be pre-treated usingpaper tape.

Three acceptable methods oftreating Kal-Kore joints are:

DRYWALL PAPER TAPETREATMENT METHOD1. Trowel Kal-Kote Base

Plaster, Uni-Kal or X-KALibur over joint linefilling the channel formedby the tapered edges of theKal-Kore board in an evenfashion.

2. Center drywall paper tapeover the joint line andembed the tape into thesoft plaster using a troweland level the joint. Tapethe full length of the joint.

3. Allow the treated joints toset prior to general plasterapplication.

13

STA-SMOOTH PAPER TAPETREATMENT METHOD1. Mix Sta-Smooth Compound

per instructions onpackage. Do notcontaminate the compoundwith other materials, dirtywater or previous mixes.Do not retemper.

2. Apply the Sta-SmoothCompound to the joint byhand or machine tool. Thedrywall paper tape must becentered over the joint lineand embedded into the softcompound. Do not over-trowel to a slick surface.Leave the surface rough toprovide mechanical keyingof the plaster.

3. Allow the treated joints toset and dry prior to generalplastering.

KAL-MESH TREATMENTMETHODDo not use self-adhering

mesh.1. Center and secure Kal-

Mesh over all joints andinterior angles with 1/4" or5/16" staples.

2. Position staples a maximumof 24" apart as follows:A. Joints: at alternate edgesfor the run from end to endand directly opposite oneanother at either end.B. Angles: along ceilingedge only for wall-to-ceiling angles. Along oneedge for wall-to-wallangles.

3. After the first staples areplaced at the end of a jointor angle, pull unstapledKal-Mesh as staplingproceeds to ensure that it will lie flat against theKal-Kore.

4. Pre-treat all joints and Kal-Beads with Kal-Kote, Uni-Kal or X-KALibur Plaster.Tightly trowel over jointline in both directions toprevent voids, feathering to a maximum width ofabout 6".

5. Allow the treated joints toset prior to general plasterapplication.

PLASTERINGNote: Application shall

conform to ASTM C 843.The same general job

conditions used in goodconventional plasteringpractice should bemaintained. However,because Veneer Plastercoats are thin, particularaction must be taken to

guard against dryouts(primarily avoiding directexposure to concentratedsources of heat and drafts.)

Special attention should alsobe given to temperatureconditions under which thesystem is installed. Both“in-place” and applicationperformance of individualVeneer System componentswill be greatly enhanced ifall construction areas andmaterials are at a suitabletemperature equilibriumbefore, during and afterinstallations. During coldweather, maintain atemperature 55˚F (13˚C) to70˚F (21˚C) before, duringand after installation of allsystem components untilveneer plaster has dried.

MIXINGEquipment: Mixing should be

done with a high-speedmechanical mixer. Apaddle-type agitator fittedto a 500-600 RPM heavyduty, 1/2" electric drill anda clean, smooth-sideddrum of convenient sizeare recommended forrapid, efficient mixing of allKal-Kote Plaster types.

Water Ratios: Use only clean,fresh water suitable forhuman consumption.Basecoat: 10-12 qts. per 80lb. bag. Smooth Finish: 18-20 qts. per 50 lb. bag.Texture Finish: 11-12 qts.per 50 lb. bag. Uni-Kal andX-KALibur: 13-15 qts. per50 lb. bag.

PROCEDURE1. Put all but 1 to 2 qts. of the

proper water volume in asuitable mixing drum.

Note: Starting with aninsufficient amount ofmixing water will seriouslydegrade mixing andapplication performance.

2. Add plaster and allow tosoak for about 1 minute oradd plaster as mixer isturning, then mix untiluniformly wetted.

3. Add remaining water andmix sufficiently to obtaindesired lump-free materialfluidity.

Note:A. Mixing periods greater

than 5 minutes will not be required if properequipment and procedureare used.

B. Mix no more than two bagsper batch to avoid mixingtoo far in advance ofapplication.

C. Caution is advised againstmixing more than twosuccessive batches withoutthorough equipment clean-up to avoid undue setacceleration.

D. Avoid the practice ofmixing partial bags sincethis leads to difficulty inmaintaining uniformmaterial qualities.

JOB SETTING ADJUSTMENT1. Basecoat and Finish

Plasters: Small amounts ofcommercial retarder orcommercial gypsum typeaccelerator may becautiously used to adjustsetting time when extremeconditions demand. Whencommercial retarder oraccelerator is used, add tomixing water directly, or inpreviously prepared watersolution form to obtain themost uniform effect.

2. Never use gauging ormoulding plasters in placeof commercial acceleratorsince they can adverselyaffect working qualities.

KAL-KOTE APPLICATIONOVER KAL-KOREBasecoat Over Kal-Kore1. Tightly scratch material into

previously treated jointsand cornerbeads, thenimmediately scratch-intightly over the wall and/orceiling area.

2. Double back over the areajust troweled with materialfrom the same batch,bringing total thickness upto 1/16" minimum.

3. When plaster has “takenup,” eliminate excessivetrowel marks and fill allsurface voids andimperfections to obtain areasonably uniform surface.Do not over-trowel to aslick surface. Roughen theunset basecoat plastersurface with a serrateddarby or lightly wire rake toprovide mechanical keying

for the finish plaster when necessary.

Smooth Finish Over Basecoat1. Apply only over properly

prepared Kal-Kote basecoatplaster. Scratch-in tightly,then double back withmaterial from the samebatch immediately tocreate a uniform coat notexceeding 1/16" in averagethickness.

2. Remove trowel marks, “catfaces,” and other majorsurface imperfections by“drawing-up” or “layingdown” the surface withlight trowel pressure whenplaster has stiffened.

Use water sparingly if needed,but do not over-trowel orover-water because thisaggravates any normaltendency for blisteringwhen working over lowsuction bases. Suchblistering will be eliminatedby the final water-trowelingoperations.

3. Water-trowel to densifyand polish the surface tothe desired degree whenplaster has set, eliminatingany blistering if present.Never use a felt “blisterbrush” as a substitute forwater troweling!

4. Uni-Kal and X-KALiburPlaster may be substitutedfor Kal-Kote Smooth Finish.

Texture Finish Over Basecoat1. Apply per (1) under Smooth

Finish.2. When plaster has stiffened,

float its surface to anydesired finish.

Do not float the soft surface of plaster which hasalready set.

Up to equal parts by weight ofclean, graded silica sandmay be added to Uni-Kaland X-KALibur to aidtexturing.

09 26 13/NGC


Veneer plaster performs wellin high traffic areas such as

stairways and halls.

UNI-KAL OR X-KALIBURAPPLICATION OVER KAL-KORE1. Tightly scratch material into

previously treated jointsand cornerbeads, thenimmediately scratch-intightly over the wall and/orceiling area.

2. Double back over the areajust troweled with materialfrom the same batchbringing total thickness upto 3/32" minimum.

3. Begin finish troweling attime of initial set, usingwater sparingly. Finaltroweling must beaccomplished beforecomplete set takes place, asevidenced by darkening ofthe surface.

Note: Uni-Kal or X-KALiburmay be applied to producea textured finish.A. When Uni-Kal or

X-KALibur is mixed, addup to but not exceeding50 lbs. of silica sand,texturing grade, per50 lb. bag of plaster.

B. The sanded Uni-Kal orX-KALibur mix shouldbe scratched-in tightlyover the plastering base.Immediately doubleback over the area justtroweled with materialfrom the same batch.

C. When plaster is welltaken up, float to thedesired texture finish.

VENEER PLASTERS DIRECT TO BOND-COATEDMONOLITHIC CONCRETEDESCRIPTIONThe Kal-Kote System,

consisting of a basecoatplaster and a finish coatplaster, Uni-Kal or X-KALibur may be applieddirectly to monolithicconcrete treated with abonding agent.

LIMITATIONS1. Surface to be plastered shall

be treated with a bondingagent applied according tomanufacturer’s directions.The performance of thissystem is the soleresponsibility of thebonding agentmanufacturer.

2. Concrete should be agedat least one month prior toplastering.

3. Kal-Kote Smooth orTexture Finishes are notdesigned for directapplication to concrete,but must first have Kal-Kote Base Plaster appliedto fill and level surface.

4. Do not apply system to theinterior side of exteriorwalls below grade. To useabove grade these wallsshall be kept dry and shallhave been properlywaterproofed on theexterior side to preventwater penetration.

APPLICATION PROCEDURESNote: Application shall

Veneer plaster walls are particularly suited to accommodatewall situations where light conditions require smooth, evenexpanses of wall.

The Veneer plaster wall system is particularly suited toresidential and commercial construction in areas which needstrength for special architectural details, and unusual design elements.

VENEER PLASTERS DIRECTTO UNIT MASONRY DESCRIPTIONThe Kal-Kote System,

consisting of a basecoatplaster and a finish coatplaster, Uni-Kal or X-KALibur, the one-coatsystem, may be applieddirectly to masonry surfacesproviding the followingrecommendations arefollowed.

RECOMMENDATIONS1. Surface must be free from

dirt, grease, oil, mold,parting agents, or anymaterial which will preventplaster adhesion.

2. When erecting masonry,strike joints flush. Ifmasonry has recessedjoints, fill joints flush tomasonry surface withbasecoat plaster, Uni-Kal orX-KALibur and allow to set.

EXTERIOR CORNERSInstall cornerbead with

adhesive at least 4 andpreferably 16 hours beforeplastering. Apply acontinuous bead ofadhesive approximately1/4" x 1/4" along the insideof both cornerbead flanges.Press the bead firmly overthe corner so that adhesiveis in continuous contactwith masonry surface.Align bead and allow tostand undisturbed at least 4 hours.

KAL-KOTE APPLICATIONNote: Application shall

conform to ASTM C 843.Proceed with the full field of

the wall by scratching-intightly, then double backimmediately with materialfrom the same batch to aminimum thickness of1/16" over the blocksurface, or as required tolevel.

Kal-Kote Finishes should bekept as thin as possible andapplied as described on page 44 and 51.

UNI-KAL OR X-KALIBURAPPLICATIONProceed with full field of the

wall by scratching-intightly, then double backimmediately with samebatch of material to aminimum thickness of3/32" over the blocksurface.

Caution: Since Uni-Kal or X-KALibur is a one-coatmaterial system, exercisecare in leveling the wall tocompensate for the unevensuction.

VENEER SYSTEMS APPLIEDTO MASONRY WITH ZFURRING CHANNELSYSTEMDESCRIPTIONThis system consists of a

Z Furring Channel, rigidinsulation and thecomponents of the Kal-Kote

and Uni-Kal or X-KALiburVeneer Plaster Systems.The Z Furring Channel ismanufactured fromgalvanized steel (.0179"min. base steel) and isproduced with web depthsof 1", 1 1/2" and 2". Thefurring channel which isapplied to a masonry wallholds the insulation inplace and the wide flangeserves as framing for theapplication of the Kal-Koreplastering base.

LIMITATIONS1. Since the interior wall

surface will take thegeneral configuration of themasonry wall, it may benecessary when applyingthe system to unit masonryto use portland cementplaster to bring the wall toa plane surface.

2. This system is mainly fornew masonry construction.On well-cured concrete ormasonry, it may be difficultto properly drive fasteners.

3. Power-driven fastenersshall be used only forattachment to monolithicconcrete surfaces.

4. Kal-Kore should be appliedwithin 24 hours of foamapplication.

09 26 13/NGC


Design flexibility is achieved with veneer plaster systems.

APPLICATION PROCEDURES1. Begin application of

Z Furring members bypositioning first channelvertically at a corner,locating it on the walladjacent to the wall beinginsulated first.

The insulation thicknessdetermines the distance ofZ Furring web from wallbeing insulated. At theappropriate distance, withwide flange pointingtoward applicator, secure Z Channel with appropriatefasteners, spaced 24" o.c.driven through short flange.(Note: Power-drivenfasteners are notrecommended for use with masonry block.)

Install 24" wide floor-to-ceiling insulation board,pressed snugly against webof first Z. Install next Z withthe wide flangeoverlapping the edge of thefirst insulation board.Fasten Z to wall throughnarrow flange. Continue inthis manner with Z Furringmember 24" o.c. to end ofwall. Locate last Z so thatweb is located a distanceequal to insulationthickness from adjoiningwall. Cut last insulationboard to fit remainingspace.

At exterior corner, attach the Zthrough its wide flange withnarrow flange extendingbeyond the corner. Beginwith a narrow strip of floor-

to-ceiling insulation, widerthan insulation thickness,but not exceeding 3".Continue application offurring and insulationprogressively as describedabove.

At windows, doors and trimareas, use wood nailers,nominal 2" wide xinsulation thickness plus1/32". Use the nailers alsoat wall-floor angles tosupport trim and providebacking for base.

2. Apply Kal-Kore to theflanges of Z Channel with1" Type S screws spaced12" o.c. Normally, verticalapplication of Kal-Kore isrecommended; however,for installations 8' or less inheight, horizontalapplication may bepreferred since the numberof joints would be reduced.

3. Apply Kal-Mesh and Kal-Korner Bead according toprocedures described onpage 50 and 51.

4. Mix and trowel on Kal-KoteBase and Finish Plaster orUni-Kal Plaster asdescribed on pages 46, 51and 52.

PAINTING PLASTERVarious job conditions such as

suction differences, wet oronly partially dry walls, andreactions between paint andlime may cause unsatisfactorypaint finishes, particularlyon new construction.

Alkali-resistant primersspecifically formulated foruse over new plaster willpermit decorating with oilor latex type paints. Qualitypaint products should beused and manufacturers’recommendationsfollowed. Finished plastershould be painted orcovered to concealpossible discoloration. Thepaint system should besuitable for use over plastersurfaces that contain lime,which has a high pH of 10-13.

It is essential that plaster besound and completely drybefore painting. Undergood drying conditions,veneer plaster may bepainted 48 hours afterapplication.

High build, heavy duty andspecial purpose coatingssuch as Epoxy are notrecommended over veneeror job gauged lime puttyfinishes.

In all cases, the paintmanufacturer should beconsulted and approvepaint system suitability foruse with gypsum/limefinish plaster.

STORAGEGypsum plaster must be kept

dry before use. Storageconditions vary withlocation and seasonalchanges, which may affectstorage life. Theseconditions may affectproduct characteristics suchas setting time, workingqualities, componentseparation, or lumping, etc.Such aging is normally afunction of exposure tohumid air, temperature,and physical support inwarehousing. Adversestorage conditions orprolonged storage mayaffect the working qualitiesof the product. Rotateinventory frequently forbest results.

METRIC CAPABILITIESThe Federal Government has

mandated that each federalagency make a transition tothe use of metric units inall federal procurement,grants and business-relatedactivities. NationalGypsum Company, incomplying with this order,provides a full line of gyp-sum board products in“hard” metric dimensionswith regard to width andlength. Standard boardofferings are made in thewidth of 1200 mm and alength of 3600 mm. Jobsize lengths are availableon a special order basisrequiring minimum ordersand extended lead times.Contact your localNational GypsumCompany representative forfurther information.Thickness of gypsum boardwill be “soft” converted tothe metric equivalent.

ENVIRONMENTALCONDITIONSMaintain a room temperature

of not less than 40˚F (4˚C)during application of gyp-sum board except whenadhesive is used for theattachment of gypsumboard. For the bonding ofadhesive, joint treatment,texturing, and decoration,the room temperature shallbe maintained at least at50˚F (10˚C) for 48 hoursprior to application andcontinuously thereafteruntil completely dry.

Note 1: Precaution–When atemporary heat source isused, the temperature shallnot exceed 95˚F (35˚C) inany given room or area.

Note 2: Precaution–Maintainadequate ventilation in theworking area during instal-lation and curing period.

Protect gypsum board productsfrom direct exposure to rain,snow, sunlight, or otherexcessive weather condi-tions.

GUIDELINES FORPREVENTION OF MOLDGROWTH ON GYPSUMBOARDGypsum board does not gen-

erate or support thegrowth of mold when it isproperly transported,stored, handled, installed,and maintained. However,mold spores are presenteverywhere and whenconditions are favorable,mold can grow on practi-cally any surface.Observing these guide-lines will help minimizethe potential for moldgrowth on gypsum board.Gypsum board must bekept dry to prevent thegrowth of mold.

Transportation and ReceivingGypsum board must be pro-

tected during transit with aweather-tight cover ingood condition.

Plastic shipping bags areintended to provided pro-tection during transit onlyand must be promptlyremoved upon arrival ofthe load. Failure toremove the shipping bagcan increase the likeli-hood of developing condi-tions favorable to thegrowth of mold.

Storage and HandlingGypsum board must be

stored in an area that pro-tects it from adverseweather conditions, con-densation, and other formsof moisture.

Job site conditions that canexpose gypsum board towater or moisture must beavoided.

Gypsum board must bedelivered to the job site asnear to the time it will beused as possible.

ApplicationProvisions must be made to

keep gypsum board drythroughout application.

Gypsum board that has visi-ble mold growth must notbe used.

Gypsum board on walls mustbe applied with a mini-mum 1/4" (6.35 mm) gapbetween the gypsumboard and the floor.

Gypsum board must not beapplied over buildingmaterials where condi-tions exist that are favor-able to mold growth.

Maintenance FollowingApplication

Essential elements of soundweather tight buildingenvelope must be properlymaintained, such as theroof, sealants, windows,etc.

Immediate and appropriateremediation measuresmust be taken as soon aswater leaks or condensa-tion sources are identified.

Routine cleaning and mainte-nance operations must beperformed so as to preventsaturation of the gypsumboard.

DESCRIPTION

Gold Bond® BRAND GypsumBoard comes standard withGridMarX™ guide marks,printed on the paper sur-face. These guide marksalign with standard build-ing dimensions and help toquickly identify fastenerlines for stud and joistframing. Using GridMarX,accurate cuts can be madewithout having to drawlines. GridMarX also assistwith quick identification ofnail/screw pattern.

GridMarX guide marks run themachine direction of theboard at five points in 4"increments. Marks runalong the edge in bothtapers and at 16", 24" and32" in the field of theboard. The marks cover

easily with no bleed-through using standardpaint products.

Vertical Application - In a ver-tical application, GridMarXserve as a guide mark tohelp identify the exactlocation of framing mem-bers behind the gypsumboard, eliminating theneed for field applied vertical lines.

Horizontal Application - In ahorizontal application,GridMarX serve as a reference mark to helpidentify the location offraming members behindthe gypsum board. (If fram-ing member is located 2" tothe right of the GridMarXat the top edge of theboard, it will be located 2"to the right down the faceof the board.)

Fire and sound ratings forbuilding systems utilizinggypsum board are dependenton the core type andthickness of the gypsumboard, its application inconjunction with thecomponent parts, and themanner in which it isapplied.

Tests for fire resistance andsound transmission,performed by independentlaboratories, have resulted inspecific ratings for walls/partitions; floor/ceilingassemblies; shaftwalls,stairwells and areaseparation walls; andcolumns. For maximum fireresistance and sound control,double layer construction isgenerally recommendedsince the additional massfurther retards heat and noisepenetration.

Gypsum board can be installedto both metal and woodframing using nails, screwsor adhesives in combinationwith nails or screws. In manyinstances, the applicationwill dictate which fasteningmethod is appropriate.

Control joints may be necessaryto prevent cracking in thegypsum board facing ofdrywall systems, especiallyin areas where structuralelements such as slabs,columns or exterior wallscan bear directly on non-load-bearing partitions. Torelieve the stresses whichoccur as a result ofmovement induced bychanges in moisture,temperature or both, controljoints are required in bothpartitions and ceilings.

DESCRIPTION

Gold Bond® BRAND Gypsum Board

Gypsum Board is the name fora family of board productsconsisting of anoncombustible core,primarily of gypsum, with apaper surfacing on the face,back and long edges.*

The popularity of gypsum boardresults from a number offactors. First, it takes virtuallyany decoration – from paintor textures to vinyl andpaper laminates. It also lendsitself to creative shaping ofinterior surfaces, allowingthe maximum in designflexibility. Gypsum board isan economical alternative toother products. Because it islightweight, it is easy tohandle for speedyinstallation. With its naturalproperties, it is durable yeteasy to repair. In addition,gypsum board’s fireresistance and sound controlcapabilities furtherdemonstrate its desirabilityin building systems.

Ever conscious of theenvironmental challengeswe face in today’s world,National Gypsum producesits gypsum board with 100percent recycled paper onboth the face and back.

Gold Bond gypsum board isavailable with a variety ofedge configurations. For easyjoint finishing, the taperededge is preferred to providea monolithic surface. Wherejoints will be exposed,square or beveled edgesshould be considered.National Gypsum alsomanufactures gypsum boardwith proprietary edgeconfigurations made toaccommodate a variety ofwall systems and finishingtechniques.

contains about 21 percentwater. When the board isheated, the water in thecore begins to evaporateand is released as steam,retarding heat transfer. Fire-Shield gypsum boardremains noncombustible.However, as shrinkageoccurs because of the lossof water volume, cracksoccur which permitpassage of fire and heat. To lessen this process, Fire-Shield gypsum boardis formulated by addingnoncombustible fibers to the gypsum to helpmaintain the integrity ofthe core as water volume is lost while providinggreater resistance to heattransfer.

For additional fire protection,Gold Bond Fire-Shield Cproducts are formulatedwith a mineral coreadditive which expandswhen subjected to heatwhich aids in holding thegypsum board together.

Fire-Shield gypsum boardsalso can be used ascolumn protection,delaying the rapid transferof heat to reduce thelikelihood that structuralmembers will lose strengthand fail to carry theintended load.

FIRE RESISTANCE RATINGSFire resistance ratings

represent the results of tests on assemblies made up of specific materials in aspecific configuration. When selecting construction designs to meet certain fire resistance requirements, caution mustbe used to insure that each component of the assemblyis the one specified in the test. Further, precaution should be taken that assembly procedures are inaccordance with those of the tested assembly. (For copies of specific tests,call 1-800-NATIONAL.)

Gypsum board joints atopenings shall be locatedso that no end joint willalign with edges ofopening unless controljoints will be installed atthese points. End jointsshall be staggered, andjoints on opposite sides ofa partition shall not occuron the same stud.

THE SECRET IS IN THE SHAPE OF THE JOINT AND THESTRENGTH OF THE COMPOUND

Standard tapered-beveled edge configuration.

Round edge configuration.

Easier Scheduling – Tapingwith Sta-Smooth Com -pounds and applying thefirst finishing coat, evenbefore the Sta-Smooth usedfor taping has dried, allowseasier job scheduling forthe drywall contractor andfinisher. This is particularlyadvantageous under slowdrying conditions.

The Sta-Smooth System produces a superior joint because theSta-Smooth Compounds are a hardening-type compound thatis not affected by humidity once it has hardened and dried. Italso maintains its hard core even with moisture added by theuse of the regular joint compounds for the finishing work. Sta-Smooth Compound firmly bonds the tape to the board and the board “V” edges to each other making a strong,rigidized joint.

Consult your local National Gypsum sales representative foredge configuration available in your market.

Gold Bond® BRAND Sta-Smooth® Gypsum Board

Sta-Smooth is a drywall system offering maximumjoint strength and easyapplication. It can be usedin any gypsum drywall system where conventionaltypes of gypsum board arerecommended. This system features Sta-SmoothBrand gypsum board with aunique edge. The two edgeconfigurations relieve jointdeformity problems causedby twisted framing,damaged gypsum boardedges, poor alignment andextremes in humidity andtemperature. Regular Sta-Smooth Boards areavailable in 1/2" thicknesses, 4' wide and incustomary gypsum boardlengths. The Sta-SmoothSystem is also composed ofProForm BRAND Sta-SmoothJoint Compounds, ahardening-type tapingcompound and regularGold Bond tape andfinishing compounds.

ADVANTAGESImproved Durability – The

Sta-Smooth System produces a smooth, flat,durable surface that relievesbeading, ridging and otherjoint deformity problems.

Greater Speed – All flat joints in the Sta-SmoothSystem are filled and tapedwith any Sta-SmoothCompounds all in one easyoperation, the same as conventional gypsum boardapplication methods. Sta-Smooth Compounds or regular compounds can beused to tape inside corners,cornerbeads, and spot fasteners. Regular ProFormfinishing compounds orSta-Smooth compounds areused for the remainingfinishing coats.

Easier Handling – Theimproved edge designs onSta-Smooth Boards makeshandling easier with greatercomfort to the hands.

No Special Equipment – Allconventional fasteners,adhesives, and gypsumboard application tools (T-squares, knives, etc.) can beused to apply Sta-SmoothBoards. Nothing new tobuy.

Alignment – Sta-Smoothboard with its unique edge(either configuration)allows for easy alignmentof the boards in the sameway as conventionaltapered edge board. Thetaper is scientificallydesigned to reducecrowned joints.

Stronger Bond – The bondingarea of the Sta-SmoothJoint Compounds areincreased with the “V”edge boards. The Sta-Smooth Joint Compoundused to bond the joint tapeand fill the joints is a hardening-type, high density material with low shrinkage characteristics.

Strength – The Sta-Smoothjoint shape and the jointcompound are developedto provide greater massand integral bond forincreased strength. Sta-Smooth Joint Compoundsadd considerable strengthwhich is unaffected by the amount of moisturenormally introduced into astructure that could causeridging or beading withconventional joint compounds.

Cost – If application techniques are followed asrecommended, the Sta-Smooth System should costno more and can cost considerably less than conventional gypsumboard drywall jointfinishing. The initialsavings are immediatelydemonstrated with reducedtravel time that results fromthis perfected 2-trip, 3-stepjoint finishing system.Future cost savings will berealized with reduced callbacks.

Better Butt Joints –Recommended with the Sta-Smooth System is animproved technique forproviding a smoother, flatter, stronger butt joint.Although this techniquecould be used in conventional drywall work and produce betterbutt joints, it is furtherimproved by the use of thehigh strength Sta-SmoothCompound.

Note: Sta-Smooth Gypsum Board may be used with any of theGypsum Drywall Systems described in this GypsumConstruction Guide.

All specifications for the application of gypsum board asdescribed in this literature may also serve for the applicationof Sta-Smooth Boards. Any deviation from thesespecifications is as indicated below.

A. BOARD APPLICATION: Position each Sta-Smooth Board sothat the long edges are in light contact with the edges of theprevious boards. All boards positioned to form butt jointsshould have a gap approximately 1/16" between the boardends. This spacing can be assured by driving 2 extra fastenersat the end of the board to act as temporary spacers beforeabutting the next board. When the boards are fastened inplace, drive the temporary spacers flush with surface. Whengypsum board is applied horizontally, recess all butt joints onthe job by shimming the face of the studs (or joists), on bothsides of the studs (or joists), on which the joint will fall. Theshim can be pressed paper, thickness of building felt or other suitable materials not to exceed 1/16" thickness and as wide asthe stud or joist. It should be 6" longer than the butt joint andapplied to the face of the stud or joist with staples or nailsallowing the shim to extend under the edge of the abuttingboards of gypsum board to assure that the board facingsremain on the same plane.

B. CORNERS AND OPENINGS: All exterior corners and allopenings that require joint treatment should receive protective reinforcement of ProForm Multi-Flex Tape Bead orSteel Cornerbead or Steel Casing Bead as required.

C. TREATMENT OF JOINTS*: All flat Sta-Smooth gypsum boardjoints are taped with ProForm BRAND Sta-Smooth Compounds,making sure that a sufficient amount of compound is forcedinto the “V” joint and spread under the tape to form a solidfoundation for the finishing coats.**

1. As soon as the Sta-Smooth Joint Compound used for taping hashardened, the first finishing coat can be applied even whenthe Sta-Smooth Compound is still wet.

2. When the first finishing coat is completely dry the second finishing coat can be applied. Any of the ProForm JointCompounds may be used for the finishing coats.

3. Sta-Smooth Joint Compounds are recommended for the firstcoat on nail or screw heads. Regular finishing compoundsmay be used for subsequent spotting of the fasteners. Sta-Smooth Compounds are also recommended for the first coaton cornerbead and followed by one or more finishing coatsas required of regular ProForm Joint or Topping Compounds.

4. The inside corners may be treated with any of the ProFormJoint Treatment Compounds recommended for taping. If atwo-trip joint treatment operation is planned, the inside corners are taped with Sta-Smooth Joint Compounds. Thiswill permit finishing one side of the inside corners the firstday. Cornerbead is treated with Sta-Smooth Compounds if atwo-trip operation is employed.

*Alternate Method: When mechanical tools are to be used for taping joints, Sta-Smooth Compounds are used to fill the “V”joint only. Other ProForm Joint Compounds are then used tobed the tape and finish the joints. (See page 69.)

**Sta-Smooth, Sta-Smooth HS and Sta-Smooth Lite JointCompounds are recommended for pre-fill or tape/bed coatoperations in the Sta-Smooth system.

See page 63, Environmental Conditions and Limitations.

3. Second Finishing Coat

TAPING AND FINISHING WITH MECHANICAL TOOLSTaping – Taping tools such as the “banjo” and “hopper” types are recommended for

taping the flat joints with Sta-Smooth Compounds and the inside corners with ProFormregular joint compounds or with Sta-Smooth Compounds. Automatic taping tools arenot recommended for use with hardening-type compounds. Mechanical tools can beused for taping the inside corners when a ProForm regular joint compound is used.When automatic taping tools are used for taping the flat joints, the “V” formed by theedges of Sta-Smooth board on the flat joints and all spaces between the gypsum boardedges on butt joints are prefilled with Sta-Smooth Compounds and allowed to harden(30 minutes longer than the set time designated on the bag) prior to taping with aregular ProForm joint compound.

Finishing – Mechanical type finishing tools can be used in the normal manner for thefinishing operations of the Sta-Smooth System since conventional ProForm finishingcompounds are used.

MIXING INSTRUCTIONSProForm BRAND Sta-Smooth Compounds are available in 20, 45, 90 and 210 minute set

times. MIX NO MORE COMPOUND THAN CAN BE APPLIED IN THE DESIGNATEDSET TIME. Contact your National Gypsum Company Representative for availability. A plastic container is recommended because of its ease in cleaning between batches.Do not use a wood or aluminum bucket. Add the compound gradually to clean waterwhile stirring. Note: Use only fresh, clean water suitable for human consumption. Mix at the ratio of 13-14 pints of water to the 25 lb. bag. Mix the compound free oflumps with a mechanical mixer or by hand. Mechanical mixing is recommended.Allow to stand 5 minutes as a “wetting” period and remix to further improve theworking qualities. If a slightly thinner compound is desired, add an additional pint ofwater, or less, after the compound is thoroughly mixed.

INSTALLATION

APPLICATION AND FASTENINGSta-Smooth Boards may be nailed, screwed or adhesively applied to wood studs or

furring, or screwed or adhesively applied to steel studs or furring, using conventionaltype and length of fastener. All fasteners shall be applied a minimum of 3/8" (maximum 1/2") from the edges and ends of each board. Then treat the joints in three simple steps.

CONVENTIONAL TAPING AND FINISHING1. Fill Joint And Bed Tape SimultaneouslyAll flat gypsum board joints are to be filled and taped in one operation with ProForm

BRAND Sta-Smooth Compounds, using ProForm Paper Tape in the conventionalmanner. When Sta-Smooth HS tape is used, the self-adhering fiberglass mesh tape isfirmly pressed to the gypsum board, spanning the joints. Sta-Smooth Compounds canthen immediately be applied to the joints. The compound must be forced through thetape to fill the channel formed by the “V” edges of the Sta-Smooth gypsum board. Allinside corners may be taped using regular ProForm compounds. Sta-SmoothCompounds are used for the first coat on nail or screw heads and will decreaseproblems with fastener imperfections. Inside angles, first and second finishing coatsmay be done using regular ProForm joint compounds.

2. First Finishing CoatAs soon as the Sta-Smooth Compound used for taping has hardened, the first finishing

coat may be applied on the flat joints even before it is dry. Any ProFrom joint compound may be used for this operation. A second coat may be applied at this timeto nail or screw heads, one coat on cornerbead if Sta-Smooth Compound was used forthe first coat.

3. Second Finishing CoatAs soon as the compounds used for the previous steps have thoroughly dried, a second

finishing coat is applied to all flat joints using ProForm Joint Compound or ToppingCompound. A third coat is applied over nail or screw heads and on cornerbead asrequired. The unfinished side of the inside corners is also finished at this time.

STA-SMOOTH ROUND EDGE REQUIRES PRE-FILLING PRIOR TO BED & TAPINGApplication Instructions For Round Edge Sta-Smooth Gypsum Board1) Mix Sta-Smooth Joint Compound, Sta-Smooth Lite Joint Compound or Sta-Smooth HS

Joint Compound as per bag instructions. Care should be taken to mix no more compound than can be applied in the designated set time.

2) Pre-fill all joints formed by the abutting round edge Sta-Smooth Gypsum Boards withSta-Smooth Compound, Sta-Smooth Lite Joint Compound or Sta-Smooth HS JointCompounds using a conventional joint finishing knife. Fill joints, level and wipe offexcess compound to the lowest level of the taper, allowing enough room for embedding the tape. Allow prefill material to harden prior to application of tape andbed coat.

3) Finish joints in the normal manner.

Installation of Hi-Abuse XPGypsum Board should be consistent with methods described in the standards references noted. For bestperformance, use verticalapplication.

GridMarX®

Hi-Abuse® BRAND XP GypsumBoard comes standard with GridMarX® guide marksprinted on the paper surface.These guide marks align withstandard building dimen-sions and help to quicklyidentify fastener lines for studand joist framing. Using GridMarX, accurate cuts canbe made without having to draw lines. The use of GridMarX also provides quick identification and uniform nail/screw patterns.

GridMarX guide marks run themachine direction of the board at five points in 4"increments. Marks run alongthe edge in both tapers andand at 16", 24" and 32" in the field of the board. The marks cover easily with nobleed-through using stand-ard products.

Vertical Application - In a vertical application, GridMarX serves as a guide mark to help identify the exact location of framingmembers behind the gypsumboard, eliminating the needfor field-applied vertical lines.

Horizontal Application - In a horizontal application,GridMarX serves as a reference mark to helpidentify the location of framing members behind the gypsum board. (If framingmember is located 2" to the right of the GridMarX at thetop edge of the board, it willbe located 2" to the rightdown the face of the board.)

Provides greater resistance to surface abuse, indentationand impact than fiber-rein-forced gypsum panels.

Hi-Abuse XP smooth facepaper is highly resistant toscuffing when sandinggypsum board joints and fasteners providing a superior surface for deco-ration.

Board has been designed toprovide extra protectionagainst mold and mildewcompared to standardgypsum board products.When tested by anindependent lab per ASTMD3273 (“Standard TestMethod for Resistance toGrowth of Mold On theSurface of Interior Coatings inan Environmental Chamber”),Hi-Abuse XP Gypsum Boardachieved a score of 10, thebest possible score for thistest.

The use of Hi-Abuse XPGypsum Board in actualinstallations may not produce the same results as were achieved in controlled,laboratory conditions. Nomaterial can be considered“mold proof,” nor is itcertain any material willresist mold or mildewindefinitely. When used in conjunction with gooddesign, handling andconstruction practices, Hi-Abuse XP Gypsum Boardcan provide increased moldresistance versus standardgypsum board products. Aswith any building material,avoiding water exposureduring handling, storage andinstallation, and afterinstallation is complete, isthe best way to avoid theformation of mold ormildew.

Minimum bending radii for5/8" Hi-Abuse XP Gypsum Board is 20'-0" applied lengthwise perpendicular to framing spaced not greater than 12" on center.

Gridstone® BRAND Ceiling Panels


Gridstone® BRAND prefinished ceiling panels have a non-combustible, Fire-Shield G gypsum core. The 2-mil white, stipple-textured vinyl laminate combines high light reflectance with easy cleanability.

Gridstone panels can be used for interior and exterior ceiling applications.

Gridstone Ceiling Panels install easily in standard 2' x 2' and 2' x 4' exposed grid systems. Ceiling panelshave a rigid gypsum core which provides extra resistance to sagging and warping.

A noncombustible gypsum core ensures fire safety with1 1/2- and 2-hour fire rating achievable depending on installation.

The sturdy white vinyl laminate eliminates additional finishing.

As little as 1" of material can be cut from Gridstone panels with practically none of the crumbling common with mineral fiberpanels.

For exterior application, protect grid panels from direct exposure to weather, water and continuous high humidity. Under no circumstances should water be in contact with the back of the panels.

Overlaid insulation may causeexcessive panel deflection and is not recommended where high humidity is likely to occur.

Extreme lighting conditions may distort texture appearance.

The use of strong organic solvents (such as ketones), harsh abrasive cleansers or steel wool are not recommended. These materials may cause dulling, discoloration, softening and other permanent damage to the vinyl surface.

USDA Acceptance: Gridstone panels are accepted by the USDA for use in food service and food processing areas.

RECOMMENDATIONS

Gridstone ceiling panels are designed to be mounted in standard 15/16" exposed tee grid systems or environmental type grids for severe conditions, with grids either 2' x 2' or 2' x 4'. Grid installation should be conducted according to manufacturer's specifi-cation.

Each panel must be supported on all four (4) edges.

Cross ventilation must be provided in unheated or enclosed space above ceiling panels.

General: Install panels in lay-in suspension systems with edges concealed by flanges of suspension members. Cut boards to fit tightly at borders and penetrations sothat cut edges are concealed by trim pieces and escutcheons.

Cleaning: Common dirt and stains on the vinyl surface can be removed with mild soap or detergent in lukewarm water. Use a light, scrubbing action with a cloth, sponge or soft brush.

If the suitability of any cleaning agent is unknown, check its effect on the Gridstone panel surface in a hidden area or on a scrap piece before attempting to remove a field stain.

Gridstone Ceiling Panels are not recommended for use in areas exposed to extreme or continuous moisture such as found in saunas, steam rooms, gang shower rooms or indoorpool enclosures, per ASTM C840 17.3.1.1.

DECORATIONGridstone Brand Ceiling

Panels are factory-finished decorative products which do not require painting. However, if desired, Gridstone can be painted with the following two products:1. Two coats of an alkyd or

Gold Bond® BRAND Foil Back Gypsum Board

DESCRIPTION LIMITATIONS1. Not recommended for

use where exposure to moisture and high outside temperature is extreme and continuous. Under these conditions, a qualified mechanical engineer should determine location of the vapor retarder.

2. Not to be used as a base for ceramic or other tile or as a base layer for prefinished vinyl wall boards in double-layer assemblies. Also, not to be used as a base for adhesively applied vinyl or other highly water-vapor-resistant wall coverings.

3. To prevent objectionable sag in ceilings, weight of overlaid unsupported insulation should not exceed:1.3 lb./sq. ft. for 1/2" thick boards with frame spacing 24" o.c.; 2.2 lb./sq. ft. for boards with frame spacing 16" o.c. Boards 3/8" thick must not be overlaid with unsupported insulation. Unheated attic spaces shouldbe properly ventilated.

4. Foil Back Gypsum Board is not recommended for use in hot, humid, climates such as the Southern Atlantic and Gulf Coast areas.

MATERIALSManufactured boards with

gypsum core, paper-encased with aluminum foil laminated backing.

SIZES AND TYPESThickness Width Length

1/2" 4' 6' to 16'5/8" 4' 6' to 16'

Edges: Square, tapered or Sta-Smooth.

APPLICABLE STANDARDSASTM C 1396

Gold Bond® Foil Back Gypsum Board consist of a fire-resistive gypsum core encased in heavy natural-finish paper on the face side and strong liner paper on the backside to which aluminum foil is laminated. The ends are square cut and finished smooth.

BASIC USESFoil Back Gypsum Board can be

used for exterior walls and ceilings in new construction and remodeling. The aluminum foil, laminated to the back surface, is a vapor retarder to keep interior moisture within the building at a suitable comfort level. Foruse with furred masonry, wood or steel framing, Gold Bond Foil Back Gypsum Board is effective for single-layer applications and as a base layer in double-layer applications where a vapor retarder of 1.0 perm or less is required.

ADVANTAGES1. In tests conducted according

to ASTM Test Procedure E 96 (desiccant method), 1/2" Foil Back Gypsum Board showed a performance of 0.06 perm compared to 34 perm for1/2" regular gypsum board and 28 perm for 1/2" gypsum board with two coats of flat latex paint.

2. In-place cost of Foil Back Gypsum Board installation is lower per thousand sq. ft. than a similar installation for regular gypsum board and polyethylene-film retarder installed separately.

3. Easy-to-handle Foil Back Gypsum Board is adaptable tovirtually all exterior wall and ceiling construction: wood frame, furred masonry.

Boards of maximum practical length should be used so that an absolute minimum number of end joints occur. Board edges should be brought into contact with each other but should not be forced into place.

Gypsum board joints at openings should be located so that no end joint will align with edges of openingsunless control joints will be installed at these points. End joints should be staggered, and joints on opposite sides of a partition should not occur on the same stud.

Gypsum board should be held in firm contact with the framing member while fasteners are being driven. Fastening should proceed from center portion of the gypsum board toward the edges and ends. Fasteners should be set with the heads slightly below the surface of the gypsum board in a dimple formed by the hammer or power screwdriver. Care should be taken to avoid breaking the face paper of the gypsum board. Improperly driven nails or screws shall be removed.

For best painting results, all interior surfaces, including joint compound, should be clean, dust-free and not glossy. To improve fastener and joint concealment, a prime coat of drywall primer is recommended to equalize the porosities between surface paper and joint compound.

FIRE RESISTANCE RATINGSFoil Back Gypsum Board has

not been used in fire resistance tests. Fire resistance ratings represent the results of tests on assemblies made up of specific materials in a specific configuration. When selecting construction designs tomeet certain fire resistance requirements, caution must be used to ensure that each component of the assembly is the one specified in the test. Further, precaution should be taken that assembly procedures are in accordance with that of the tested assembly. (For copies of specific tests, call 1-800-NATIONAL or 1-800-628-4662.)

RECOMMENDATIONS

Examine and inspect materialsto which gypsum board is to be applied. Remedy all defects prior to installation of gypsum board. Any defects in the finished installation due to misaligned framing or other cause will be the responsibility of the work performed under that section of the specification and such defects shall be remedied under that secton of the specification

Gypsum board should be applied first to ceiling at

right angles to framing members, then to walls.


GYPSUM SYSTEMSNonload-Bearing Steel Frame Partitions

DESCRIPTION

Steel framed drywall partitionsare comprised of steel floorand ceiling tracks, steelstuds and Gold BondGypsum Board which isattached with self-drillingdrywall screws. Metalproducts are to meet orexceed all applicableASTM standards.

Gypsum board may beapplied horizontally orvertically in single ordouble layers. In doublelayer construction, the face,or finish layer, may beDurasan panels adhesivelyapplied to the base layer.For specific fire and soundratings for this system, seetest data on pages 11through 26.

ADVANTAGES1. Openings provided

throughout the length ofthe steel studs permit theeasy horizontal routing ofwater, gas and electricalconduit. These openingsmay also be used to installC.R. Channel stiffenerswhere increased rigidity isrequired. Interruption of thefloor or ceiling track allowsthe vertical installation oflarger utilities.

2. Fire resistance: 1-, 2-, 3-and 4-hour fire ratings havebeen assigned to thesesystems (see pages 11-26).

3. Sound resistance: where a superior SoundTransmission Class isrequired, it can beachieved through the use of several variations withthis system.

TECHNICAL DATA

PARTITION HEIGHTSLight Gauge Steel Studs are

designed to frame nonload-bearing partitions whichare limited in height bydeflection resulting fromextraneous horizontalforces. For any givenhorizontal load, the amountof deflection increases asthe height of the partitionincreases.

Tables 1 and 2 on the nextpage show maximumpartition heights based onspecific design criteria. Theheight limits shown arebased on the gypsum board

and the steel studs acting asa composite section toprovide a maximumdeflection of L/120, L/240,L/360 (L = partition height ininches) with a horizontalload of 5 psf, 7.5 psf, and10 psf of partition surface.

Increased rigidity may beobtained by placingstiffener channels throughthe steel stud cut-outs, byusing two layer applicationof gypsum board or bydecreasing stud spacing.

Standard 25 and 20 gaugestuds, recommended forinterior partitions, haveheight limits as shown inTables 1 and 2. Gypsumboard must be attached tofull height on both sides ofstuds with Type S BugleHead Drywall Screws(Type S-12 for 20 gaugestuds) spaced not morethan 12" o.c. on all studswhen framing is 24" o.c.and 16" o.c. if framing is16" o.c. or less. Screwlengths must be not lessthan 3/8" greater than thetotal thickness of thegypsum board beingfastened.

Light steel 20 gauge studs aredesigned for exterior,nonload-bearing curtainwall systems, but are alsoused for interior partitionsto provide more ridigity orgreater heights than can beobtained with Standard 25gauge studs.

LIMITATIONS1. Maximum stud spacing for

single layer application of1/2" and 5/8" gypsumboard is 24" o.c. If 3/8"gypsum board is used, itmust be applied in twolayers, with the secondlayer adhesively applied;24" o.c. stud spacing maybe used.

2. Where long, continuousruns of this wall system areemployed, control jointsmust be provided every 30'or less.

3. Where structural movementmay impose direct loads onthese systems, isolationdetails are required.

4. Partitions should not beused where frequentlyexposed to excessivemoisture unless all surfaces

are waterproofed.5. To prevent weakening

due to calcining, gypsumboard should not beexposed to temperaturesover 125˚F for extendedperiods of time.

6. Gypsum board joints onsingle layer, or the facelayer on two layerapplications, shall notoccur within 12" of thecorners of door framesunless control joints areinstalled at the corners.

7. For limitations regardingselection of doors anddoorframes, refer to tableon page 92.

8. Where reference is madeto nominal gauges, 25gauge relates to aminimum base steel of.0179", and 20 gauge to.0329".

A. General: In accordance with ASTM C 754, themanufacturer’s recommendations and National GypsumCompany “Gypsum Construction Guide.”

RECOMMENDATIONS

1. FRAMINGAlign floor and ceiling tracks to ensure plumb partition.

Secure track with suitable fasteners at a maximum of 24"o.c. Position studs in track on 16" or 24" centers byrotating into place for a friction fit. Steel studs shall beinstalled with all flanges pointed in the same direction.Secure studs located adjacent to door and window frames,partition intersections and corners with 3/8" Pan HeadType S Screws driven through both flanges of studs andtracks or by using a stud clincher.

2. SINGLE LAYER OR FIRST PLYCut gypsum board to allow for a 1/8" to 1/4" gap between

gypsum board and floor to prevent potential wicking.Apply gypsum board with the length parallel or at right angles

to the studs. Center abutting ends or edges over the studflanges.

For metal framing, screws shall be Type S, of a length toprovide not less than 3/8" penetration into framing andshall be spaced 24" o.c. max. If no adhesive is used,standard fastener spacings shall prevail.

For non-fire-rated construction, locate all attaching screws12" o.c. when framing is 24" o.c. and 16" o.c. whenframing is 16" o.c. or less. For fire-rated construction,vertical application, space screws 12" o.c. in the field and8" o.c. along the vertical abutting edges unless otherwisespecified. Attach the gypsum board to Steel Studs withType S Drywall Screws using an electric, drywallscrewdriver with a #2 Phillips bit. For vertical gypsumboard application with studs 24" o.c., erect the gypsumboard on one side of the partition, screw attaching to openend of stud flange first at vertical gypsum board joints.Complete the gypsum board application to the entire sideof the partition in this manner. For the opposite side, cutthe first gypsum board 2' wide so that joints will bestaggered. Fasten this and succeeding gypsum boards to allstuds on this side. When partition face is complete, returnto the first side and complete screw attachment of gypsumboard to all intermediate studs.

Make door and window framing openings of such size thatwhen the gypsum board is secured to the studs, it will fitsnugly into the steel frames.

3. FACE LAYERMechanical attachment of face layer for fire or sound rated

constructions shall be made in accordance with thespecifications for the system selected. When the face ply isattached with mechanical fasteners and with no adhesivebetween plies, the maximum spacing and minimumpenetration recommended for screws should be the sameas for single ply application.

DESCRIPTION

STANDARD APPLICATIONStandard application (single

nailing) Regular Gold BondGypsum Board is usuallyapplied directly to woodframing members. Ceilingsare applied first, thensidewalls. Boards should beaccurately cut and jointsabutted but not forcedtogether. Horizontalapplication, long edges atright angles to nailingmembers, is preferred for itminimizes joints andstrengthens the wall orceiling. Nails shall bespaced not to exceed 7" onceilings, or 8" on sidewalls,a minimum of 3/8" and amaximum of 1/2" fromedges and ends of gypsumboard. Gypsum board nailsor annular ring nails, suchas the GWB-54 illustratedabove, are recommended.For a description of thevarious types of Gold BondGypsum Boards, refer topages 58 through 89.

DOUBLE NAILINGDouble nailing is an alternate

method of attachmentdevised to minimize nail-pops. This system requiresdoubling up on the fieldnails. The total quantity ofnails used does not double,however, since maximumnail spacing is increased to12" o.c. and conventionalnailing is used on theperimeter. Application isaccomplished by first singlenailing the field of theboard, starting at the centerand working toward endsand edges. Another nail isthen driven in closeproximity (2" to 2 1/2") toeach of the first nails. Thefirst series of nails are thenstruck again to ensure theboard is drawn tightly tothe nailing member.

FLOATING ANGLEMETHODFloating angle method of

gypsum board applicationeliminates the use of theperimeter nails at interiorcorners and where ceilingsand walls meet. Thismethod reduces the stressand strain on the board ifframing settles.Reference ASTM C 840,Section 9.

ADHESIVE NAIL-ONMETHODApply drywall adhesive to

face of studs or joists incontinuous beads.Reference ASTM C 840Section 10.

FIRE RESISTANCE RATINGSWhere fire ratings are

required, refer to pages 12, 13, 22, and 23. Forcomplete constructiondetails consult the specifictest report.

SCREW APPLICATIONScrew application is often

preferred as the screwholds the gypsum boardtight against the framingwhen applied asrecommended. Type W 1 1/4" Drywall Screws aredriven with an electricscrew gun equipped withadjustable screw depthcontrol and a #2 Phillipsbit. If framing is spaced upto 16" o.c., screws arespaced 12" o.c. max onceilings and 16" o.c. maxon walls. If framing isspaced 24" o.c., screwspacing must not exceed 12" o.c. Minimum screwpenetration shall be 5/8" forwood studs.

RECOMMENDATIONSCut gypsum board to allow for

a 1/8" to 1/4" gap betweengypsum board and floor toprevent potential wicking.

1/2" or 5/8" gypsum boardsingle layer application isrecommended for interiorfinishing of all buildingswith wood frameconstruction. The use of

5/8" gypsum board or 1/2"High Strength CeilingBoard on ceilings willminimize sagging. Duringcold weather the use ofpolyethylene film as aceiling vapor retarder is not recommended unlessceiling insulation isinstalled prior toapplication of gypsumboard.

LIMITATIONS1. 1/4" Gold Bond Gypsum

Board should be appliedonly to existing surfacesand should not be applieddirectly to framingmembers, except whenused with other thicknessesin double layer systemstested for specific purposes.Existing walls and ceilingsshould be sound, flat, leveland without void spaces.1/4" thick gypsum boardshould be applied with acombination of mechanicalfasteners, nails or screws,and adhesive that will bondto the substrate surfacecovering. Nails or screwsshould penetrate framingspaced not over 24" o.c.Adhesive should be appliedbetween framing membersto bond the gypsum boardto the substrate.

2. 3/8" Gold Bond GypsumBoard should not be usedon nailing members over16" o.c. When applied toceilings, the gypsum boardmust be applied with thepaper bound edges at rightangles to the nailing mem-bers and shall not be usedto support insulation. 1/2"or 5/8" Gypsum Boardshould not be used onnailing members over 24"o.c. When applied toceilings with the nailingmembers exceeding 16"o.c., the gypsum boardmust be applied with thepaper bound edges at rightangles to the nailingmembers.

3. If gypsum board ceilingboards are nailed to crossfurring, these membersshall have a minimumcross section of 2" x 2"(nominal) with same

spacing limitations asabove. With screws,nominal 1" x 2" furring maybe used. Spacing of theframing members toreceive furring must notexceed 24" o.c.

4. In single ply installation, allends and edges of gypsumboard should occur overframing members or othersolid backing except wheretreated joints occur at rightangles to framing or furringmembers.

5. Hold the gypsum boardfirmly against the framingwhile fastening with nailsor screws. Start at thecenter and work towardeach end and edge,spacing the fasteners asrecommended for eachtype of application.

6. Lighting and other fixturesshall be supported byframing; do not use gypsumboard to support them.

7. Gypsum board ceilings tobe decorated with water-thinned spray texture shallbe 1/2" or 5/8" thick andapplied perpendicular tothe framing. Framing shallnot exceed 16" o.c. for 1/2" regular gypsum board and24" o.c. for 1/2" HighStrength Ceiling Board and5/8" gypsum board.

8. Gypsum board ceilings toreceive a spray texturefinish must be primed witha sealing latex primer andallowed to dry beforespraying. This is tominimize sagging of thegypsum board anddiscoloration problems.

The use of water-based spraytextures may cause un-primed gypsum board tosag when any one or moreof the following conditionsexist:

1. Unventilated buildings.2. Use of vapor retarders

under certain conditions.3. Periods of prolonged high

humidity due to eitherweather conditions orclosed building units (poordrying conditions).

4. Inadequate framing support(can occur where framingchanges direction).

5. Improper type or thicknessof gypsum board.

SCREW APPLICATIONFast, positive, fewer heads to treat.

ADHESIVE/NAIL-ONIdeal for prefinished boards.

DOUBLE NAILINGMinimizes nail-pop.

SINGLE LAYER GYPSUMBOARD APPLICATION (alsoBase Layer of Double Layer)1. NAILSNails shall be GWB-54 or

cooler type located 3/8"min. to 1/2" max. fromedges and ends of board.Nails shall be a max. of 7"o.c. on ceilings and a max.of 8" o.c. on walls, exceptfor “Double Nailing”Procedure.

2. SCREWSDrywall screws for attaching

gypsum board to woodframing shall be 1 1/4",

Type W spaced not toexceed 12" o.c. on ceilings,16" o.c. on sidewalls wherestuds are 16" o.c. and 12"o.c. on sidewalls wherestuds are spaced 24" o.c.Screws for attachinggypsum board to gypsumboard shall be Type Gspaced as required.

3. STAPLESBase layer gypsum board may

be applied with power-driven staples spaced 7"o.c. on ceilings; 8" o.c. onsidewalls. Staples shall beU.S. Standard 16 gaugegalvanized wire staples

with 7/16" wide crownwith legs having divergentpoints. Legs shall be notless than 1" long for 3/8"base board, 1 1/8" long for1/2" base board or 1 1/4"long for 5/8" base board.

4. CORNERBEADSCornerbead shall be nailed

with gypsum board nailsspaced no greater than 9"apart on each flange of thebead with the nailsopposite. In lieu of nailing,cornerbead may be crimpapplied 6" o.c. with aspecial tool.

5. ADHESIVE APPLICATIONTO FRAMING

A. Apply gypsum boardadhesive to the woodframing with a caulkinggun.

FLOATING INTERIORANGLES To minimize fastener popping

in areas adjacent to walland ceiling intersections,the floating angle methodshould be used for eithersingle or double layerapplication of gypsumboard to wood framing.This method is applicablewhere single nailing,double nailing or screwattachment is used.Gypsum board should beapplied to ceiling first.

REPAIRING NAIL-POPS Nail-pops are caused by

lumber shrinkage afterboard application; loosegypsum board; improperlyaligned, twisted or bowedframing; or impropernailing.

Pops appearing before/duringdecoration should berepaired immediately.Those which occur afterone or more month’sheating are usually causedby lumber shrinkage andshould not be repaired untilafter heating season. Torepair, renail about 1 1/2"from the popped nail alongthe framing while applyingsufficient pressure adjacentto the nail to bring board infirm contact with theframing. If the popped nail

was improperly driven,remove it. If properlydriven, reseat just belowthe board face. Removeany loose material overreseated nail before treat-ing nail heads with jointcompound andredecorating.

ADHESIVE NAIL-ONAPPLICATIONThe adhesive nail-on system

for application of gypsumboard to wood framingmembers strengthens thewall and minimizes thepossibility of nail-popping.It reduces the number ofnails in the field, providesfor intimate contact and acontinuous bond betweenthe gypsum board andwood framing. All surfacesthat come in contact withthe adhesive should be dry,free of dirt, grease, oil orother foreign materials.

SCREW APPLICATIONDrywall screws attach gypsum

board to wood or steelframing or to other gypsumboards. They pull the boardtightly to the supports,minimizing surface defectsdue to loose boards. Whenproperly driven, they makea uniform depression freeof ragged edges and fuzz.

Finish layer is temporarilynailed or braced untiladhesive dries. On walls,prefinished boards, appliedvertically, can be pre-bowed, nailed just top andbottom.

RECOMMENDATIONS1. Double layer gypsum board

application over woodframing is recommendedfor the ultimate in wallsurfacing and in areaswhere increased fireprotection and better soundinsulation are desiredbetween rooms. (For testresults see pages 13-14 ofthis guide.) Custom builthomes, commercialbuildings and party wallsbetween apartments wouldbe considered appropriateareas for double layerapplication.


09 29 00/NGC

2. Laminating is an excellentway to apply Durasan, thevinyl-surfaced gypsumboard. This methodeliminates any visible attachment.

3. Sta-Smooth Compound or Sta-Smooth Lite is recommended for laminating as well as forjoint treatment where fasthardening is required.

LIMITATIONS 1. Joints of succeeding layers

must not fall at the samelocation. For greateststrength, it is recom-mended that the boards ofeach layer be staggered sothat joints of each layer areat least 10" apart.

2. During cold weather, maintain a room temperature of not lessthan 40˚F during mechanical attachment ofgypsum board, andbetween 50˚F and 70˚F for 48 hours before lamination, joint treatment,texturing and decoration,and continuously thereafteruntil completely dry.

A. Z FURRING CHANNEL 1. Application of Foam.

Z Furring Channel is usedto secure rigid insulationand gypsum board tomasonry walls. Insulationthickness (1", 1 1/2", 2")determines depth of Zfurring web. The channel isapplied vertically andfastened to the masonrywall through the short (3/4")flange with suitablemasonry fasteners 24" o.c.maximum. Application isprogressive. After fasteningeach Z Furring Channel, a24" wide floor-to-ceiling-high insulation board is fitbetween the wall and thewide (1 1/4") flange.

2. Application of GypsumBoard. Erect Gold BondGypsum Board eithervertically or horizontally tothe Z Furring Channels.Gypsum board edges orends that run parallel to thechannels shall be centeredand abutted over channels.Fasten gypsum board with1" Type S Drywall Screwsspaced 12" o.c. Whengypsum board erection iscomplete, finish all jointsand screw heads inaccordance with ProFormJoint Finishing System.Prefinished gypsum boardmay be laminated verticallyto the channels with screwsat top and bottom.

Limitations Power driven fasteners should

be used to secure furringonly when wall ismonolithic concrete.Regular concrete nails canbe used for fastening to unitmasonry. If block is old,test nailing should be donein advance to determineoptimum size and type of nail.

B. LAMINATION 1. Application of Foam.

Insulation may be urethanefoam or extrudedpolystyrene. Expandedbead polystyrene is notrecommended. Forhorizontal gypsum board

application, install woodfurring strips (nominal 2"wide x 1/32" greater thanthe foam thickness)horizontally along the wall-ceiling and wall-floorangles, where horizontalgypsum board joints willfall, and around door andwindow openings. Forvertical gypsum boardapplication, furring stripsare required at thehorizontal wall-ceiling andwall-floor lines and arounddoor and windowopenings.

Masonry surface must be dry,clean and free of dust, dirt,form release agents, oil,grease or water solublematerials. Treat paintedmasonry as recommendedfor laminating to paintedsurfaces. Apply adhesive tothe foam insulation in 3/8"dia. beads continuouslyaround the perimeter andthrough the field in the longdirection with the beadsspaced 16" o.c. Contactadhesive manufacturer forcompatibility with foam.

Apply the foam boardshorizontally to the wallwith a sliding motion andhand press entire board toensure full contact ofadhesive and wall surface.

2. Application of GypsumBoard. ProForm All-Purpose Joint Compoundsmay be used. (Do not usewater base compounds forlaminating prefinishedboards to foam.)

Permanent nails or screws 12" o.c. are required tofasten gypsum board towood furring. Gypsumboard must be installed aminimum of 1/8" from thefloor. Use temporary nailsor bracing as necessary tohold gypsum board boardsin firm contact to the foamuntil adhesive has dried orset.

Limitations 1. Nails or screws used for

attachment of gypsumboard to furring strips mustnot penetrate through thefurring.

2. Power driven fastenersshould be used to securefurring to monolithicconcrete. Regular concretenails can be used forfastening to unit masonry. Ifblock is old, test nailingshould be done in advanceto determine optimum sizeand type of nail.

3. During cold weather, roomtemperature between 50˚Fand 70˚F must bemaintained uniformlyduring application anduntil adhesive is thoroughlydry or premises areoccupied. Provideadequate ventilation.

4. Gypsum board is notrecommended in areaswhere it will be exposed toexcessive moisture orcontinued high humidity.

5. Since the use of foamplastic insulation isregulated by many buildingcodes, consultation withlocal building authorities isrecommended beforeinstallation.

Since unprotected foaminsulation may represent afire hazard, it should becovered promptly andcompletely with gypsumboard.

INSTALLATION

Z FURRING CHANNEL HORIZONTAL INSTALLATION WITH DRYWALL ADHESIVE

DAUB METHOD USING JOINT COMPOUND

Z FURRING1. Begin application of

Z furring members bypositioning first piecevertically at a corner.Locate the piece on thewall adjacent to the wallbeing insulated first.

2. Insulation thicknessdetermines distance of Z furring web from wallbeing insulated. At theappropriate distance, andwith wide flange pointingtoward applicator, secure Z furring with appropriatefasteners through shortflange. (Note to Specifier:Power driven fasteners arenot recommended for usewith masonry block.)

3. Install 24" wide floor-to-ceiling insulation board,pressed snugly against webof first Z. Install next Z withwide flange overlappingedge of first insulationboard. Fasten to wallthrough narrow flange.

4. Continue in this manner,with Z furring 24" o.c. toend of wall. Locate last Zso that web is located adistance equal to insulationthickness from adjoiningwall. Cut last insulationboard to fit remainingspace.

5. At exterior corner, attachthe Z through its wideflange, with narrow flangeextending beyond thecorner. Begin with anarrow strip of floor-to-ceiling insulation, widerthan insulation thicknessbut not exceeding 3".Continue application offurring and insulationprogressively as describedabove.

6. At windows, doors and trimareas, use wood nailers(nom. 2" wide x insulationthickness plus 1/32"). Usethe nailers also at wall-floorangles to support trim andprovide backing for base.

7. Apply gypsum board with1" Type S Screws throughflanges of Z furring, 12" o.c.

LAMINATION1. Masonry or monolithic

concrete shall be abovegrade, dry, free of dust,loose particles, oil, greaseor other foreign material.

2. Joint compound used asadhesive shall be mixed toa consistency thick enoughto allow a 2" daub to stickto the underside of a broadknife held parallel to thefloor.

3. Apply 2" to 2 1/2" diameterdaubs of adhesive 1/2"thick, 16" o.c. in bothdirections to the masonrywall. The adhesive layoutmust provide for a row ofdaubs located a maximumof 2" from board ends, andcare must be exercised tocenter daubs on verticaljoints. No more adhesiveshall be applied to the wallthan will be covered withboard in 15 minutes.Approximate coverage forjoint compound (powder)used as an adhesive is 30-35 lbs./1000 sq. ft.

4. Cut gypsum board to allowfor 1/8" to 1/4" clearancebetween board and floor toprevent potential wicking.

5. Install gypsum board byhand pressing each boardtight to the wall makingcertain that all daubs are inpositive contact with theboard.

6. Support boards at eachcorner to keep them fromslipping to the floor by useof a concrete nail driventhrough a small block ofnominal 1" lumber.

7. Butt boards to eachpreviously positionedboard to ensure flush joints.

8. If necessary to hold boardsstraight, plumb and inproper alignment, drivemasonry nails throughsmall wood blocks and intomasonry at high pointsonly. After adhesive is dry(24 - 48 hours) removetemporary nails.

9. Fill all holes and treat jointswith tape and jointcompound.

for fast spray application to interior ceiling surfaces.Its shredded polystyreneaggregate gives this texturingproduct greater whiteness,better hide and bold accent.Recommended for interiorceilings that are formed ofnew or previously paintedgypsum board or monolithicconcrete or plaster.Available coarse, medium,and fine (40 lb. bag).

ProForm BRANDPerfect Spray EM

Perfect Spray EM is a non-aggregated texture product used to create a wide range of wall surfaces.When used in conjunction with texturedceilings Perfect Spray EM can be applied without overspray affecting the ceiling previously sprayed with (aggregated) Perfect Spray. By adjusting mixture consistency and/or varying the atomizing pressure, Perfect Spray EM creates an almost endless variety of textures, the most typical of which are Spray Spatter, Spatter Knockdown and Orange Peel. Surfaces can be finished with a coat of paint. Perfect Spray EM (nonaggregated) is specially formulated for easy mixing and easy pumping and is available in 50 lb. bags.

Perfect Spray EM Texture ApplicationTexturing can be, depending

on desired pattern, a single-or multiple-coat operationusing a spray texture gun fedby a piston or Moyno-typepump. An Orange PeelFinish is achieved with ahigh atomizing pressure andthin mix. A Spatter Finishuses a low atomizingpressure and heavy mix.Other finishes can becreated by combiningmethods in two coatoperations or trowelingspatter patterns before fullydried (Spatter Knockdown).

Caution: Where a vaporretarder has been installedabove a gypsum boardceiling, adequate ventilationmust be provided during thedrying period. Thisprecaution is necessary inorder to minimize thepossibility of gypsum boardsagging due to moistureabsorption.

Note: It is recommended that theprepared surface be coatedwith a drywall primer prior to the application of finalfinishes. See painting/wallcovering specificationin this regard.

This level should be specifiedwhere flat paints, lighttextures, or wallcoveringsare to be applied.

In critical lighting areas, flatpaints applied over lighttextures tend to reducejoint photographing. Gloss, semi-gloss, andenamel paints are notrecommended over thislevel of finish.

The weight, texture, andsheen level of wall-coverings applied over thislevel of finish should becarefully evaluated. Jointsand fasteners must beadequately concealed if thewallcovering material islightweight, containslimited pattern, has a glossfinish, or any combinationof these finishes is present.Unbacked vinyl wall-coverings are notrecommended over thislevel of finish.

The following has beenexcerpted from a consensusdocument prepared by theAssociation of the Wall andCeiling Industries-International (AWCI),Ceilings & Interior SystemsConstruction Association(CISCA), GypsumAssociation (GA), andPainting and DecoratingContractors of America(PDCA) as a guide togypsum board finishing.The members of theseinternational tradeorganizations are dedicatedto providing the bestpossible job for the mostreasonable cost. Byincorporating theappropriate sections of thisrecommended specificationinto the project documents,the architect, generalcontractor, and buildingowner can better anticipatethe final appearance of thedecorated wall and ceilingsystem.

This has also been issued bythe Gypsum Association asdocument GA-214.

SCOPEThis recommended

specification describesvarious levels of finish ofgypsum board surfacesprior to the application of specific types of final decoration. Therecommended level offinish of gypsum board walland ceiling surfaces varieswith the final decoration tobe applied and can also bedependent on their locationin a structure and the typeof illumination striking the surface. Eachrecommended level offinish is described withtypical applications.

ManufacturerRecommendations.

The recommendations ofindividual manufacturers ofgypsum board, joint tapesand compounds,accessories, drywallprimers, wallcoverings,adhesives, texturematerials, and paints mayvary from what isrecommended herein andas such are not a part ofthis recommendedspecification.

DRYWALL PRIMERApplied as a first coat to the

entire prepared gypsumboard surface with brush,roller, or spray, prior todecoration. Where finalappearance is critical, theapplication of high quality,high solids, drywall primerwill minimize mostdecorating problems.

For finish paints: A goodquality, white, latex drywallprimer formulated withhigher binder solids,applied undiluted, istypically specified for newgypsum board surfacesprior to the application oftexture materials and gloss,semi-gloss, and flat latexwall paints.

An alkali and moisture-resistant primer and a tintedenamel undercoat may berequired under enamelpaints. Consult with thefinish paint manufacturerfor specificrecommendations.

For wallcoverings: White, self-sizing, water base,“universal” (all purpose)wallcovering primers haverecently been introducedinto the marketplace for useon new gypsum boardsurfaces. These productsare claimed to minimizedamage if wallcoveringsare subsequently removed,bind poor latex paint, allowhanging over glossysurfaces and existing vinyls,hide wall colors, and to bewater washable.

TEXTURINGTexture material is applied by

brush, roller, spray, ortrowel, or a combination ofthese tools, depending onthe desired result. Texturedwall surfaces are normallyoverpainted with thedesired finish; overpaintingof textured ceiling surfacesmay not be deemednecessary where anadequate amount ofmaterial is applied toprovide sufficient hiding

shall have tape embeddedin joint compound and twoseparate coats of jointcompound applied over allflat joints and one separatecoat of joint compoundapplied over interiorangles. Fastener heads andaccessories shall becovered with three separatecoats of joint compound. Athin skim coat of jointcompound, or a materialmanufactured especially forthis purpose, shall beapplied to the entiresurface. The surface shallbe smooth and free of toolmarks and ridges. Note: It isrecommended that theprepared surface be coatedwith a drywall primer priorto the application of finishpaint. See paintingspecification in this regard.

This level of finish is highlyrecommended where gloss,semi-gloss enamel ornontextured flat paints arespecified or where severelighting conditions occur.

This highest quality finish isthe most effective methodto provide a uniformsurface and minimize the

possibility of joint photo-graphing and of fastenersshowing through the finaldecoration.

COMMENTSCritical (Severe)

Lighting Areas.Wall and ceiling areas

abutting window mullionsor skylights, long hallways,or atriums with largesurface areas flooded withartificial and/or naturallighting are a few examplesof critical lighting areas.Strong sidelighting fromwindows or surface-mounted light fixtures mayreveal even minor surfaceimperfections. Light strikingthe surface obliquely, at avery slight angle, greatlyexaggerates surfaceirregularities. If criticallighting cannot be avoided,the effects can beminimized by skim coatingthe gypsum board surfaces,by decorating the surfacewith medium to heavytextures, or by the use ofdraperies and blinds whichsoften shadows. In general:gloss, semi-gloss, andenamel finishes highlightsurface defects; textureshide minor imperfections.

Gypsum drywall shaftconstruction has becomethe preferred alternative totraditional masonry shafts.One-inch Shaftliner boardwas developed as alightweight, easy-to-installreplacement for masonry inthe interior core ofbuildings for shaftwalls,stairwells, other verticalchases and mechanicalenclosures. Shaftliner board is also used as acomponent of 2" solidpartitions, and areaseparation walls with alayer of 1/2" Regular orFire-Shield Gypsum Boardattached to each side.

Historically, heavy masonryweighing 20 to 45 lbs. persquare foot was used forshaftwall construction.With the use of Shaftliner,shaftwall assemblies weighin at a remarkably low 10to 13 lbs. per square foot.

The benefits of gypsumdrywall shaft systems go farbeyond the difference inweight alone. The corewall of a shaft can beinstalled from the exteriorof the shaft and requires no scaffolding. Erection is speedy and clean.Shaftliner also providesexcellent sound controland can achieve the fireratings necessary for today’sbuilding construction. Bestof all, gypsum shaftwallsystems are moreeconomical than masonryshaft construction.

National Gypsum producesShaftliner board with greenmoisture-resistant paper orpurple moisture/mold/mildew resistant paper onboth sides with a bevelededge configuration allowingfor simple installation intothe Shaftwall Systemframing.

Cavity Shaftwall systems are anonload-bearing drywallpartition made up of twobasic components, gypsumboard and metal framing.Gypsum board includes 1"Fire-Shield Shaftliner or 1"Fire-Shield Shaftliner XPpanels, 1/2" Fire-Shield C

and 5/8" Fire-ShieldGypsum Board face panels.1/2" XP Fire-Shield C or 5/8"XP Fire-Shield GypsumBoard face panels may beutilized for extra protectionagainst mold and mildew.The framing includes I-Studs, C-T Studs and C-Hstuds with integraltabs/flange which hold thepanels in place and J Trackfor runners at top andbottom, as well as verticallyat partition ends and toframe openings.

The Cavity Shaftwall Systemswere developed to encloseelevator shafts and othervertical chases in buildingswhere it is advantageous toerect these walls from oneside only and where fireresistance and resistance toair pressures are required.

National Gypsum CompanyCavity Shaftwall Systemsmay be constructed with C-T, C-H or I-Stud shaftwallframing.

Lightweight. Cavity ShaftwallSystems are very lightweightcompared to conventionalshaftwalls, weighingapproximately 10 lbs. persq. ft. of wall when finishedwith two layers of 1/2" Fire-Shield CGypsum Board.

Economical. Shafts can bequickly enclosed with shaftwall framing andShaftliner under mostconditions in whichinstallers can work, wellbelow temperaturelimitations for finish gypsumboard applications.

Practical. The 1" Shaftliner is faced with light greenmoisture-resistant paper andShaftliner XP is faced withpurple moisture/mold/mildew resistant paper forprotection against weatherduring installation.

RECOMMENDATIONS

FRAMING AND SHAFTLINERCAVITY SHAFTWALL1. Locate and lay out partition

floor and ceiling lines toensure plumb partition.

2. Insure accurate studspacing to maintaingypsum board face layermodule.

3. Position top and bottom JTrack with long leg towardthe shaft along ceiling, floorand vertically at columnand/or wall where erectionof shaftwall will begin.Attach with power drivenfasteners 24" o.c. max.

4. Frame all openings cut into partitions for ducts, etc.with J Track as shown inaccompanying details toprotect cut gypsum coreedges and to provideresistance to bending andother stresses.

5. Cut shaftliner panels 1" lessthan ceiling height andinstall first by placingoutside vertical edgeagainst long leg of verticaltrack, plumb and attachwith Type S 1 5/8" Screws24" o.c.

6. Place studs within flangesof floor and ceiling trackand rotate into place. Slidestud tabs/flange snugly overedge of shaftlinerpreviously installed.

7. Install next shaftliner panelbetween tabs/flange ofstuds. Continue in thismanner until end ofpartition run. Occasionallycheck spacing of studs tomaintain 24" module.

8. At end of run, cut vertical J Track at least 2" short ofpartition height. Cutshaftliner 1/4" less thanremaining width ofpartition and 2" short of full height. Lay piece ofshaftliner 2" wide x lengthof opening in floor track assupport for last shaftlinerpanel. Fit cut edge ofshaftliner into vertical trackand, holding shaftliner andtrack together, slide paper

bound edge of shaftlinerinto stud. Align last paneland fasten the vertical trackwith appropriate fasteners24" o.c. max. Fastenshaftliner to vertical trackwith 1 5/8" Type S or S-12Screws 24" o.c. Seedrawing on page 126 foralternate detail.

9. Locate shaftwall horizontalend joints within the upperand lower third points ofwall. Stagger joints inadjacent panels to avoidcontinous horizontal joint.Shaftliner horizontal endjoints do not require taping,back blocking or framing.When using I-Studs theshaftliner panels shall be ofsufficient length to engagea minimum of two I-Studtabs along the edge.

GYPSUM BOARDApply first layer of 1/2" Fire-

Shield C (5/8" Fire-Shield)Gypsum Board horizontallyto face of studs with screwsspaced 24" o.c. Applysecond layer vertically withscrews spaced 12" o.c.(Use 1" Type S Screws onfirst layer, 1 5/8" Type SScrews on second layer for25 gauge nominal framing.)(Use 1" Type S-12 Screwson first layer, 1 5/8" Type S-12 Screws on secondlayer for 20 gauge orheavier framing.) Stagger allvertical and horizontaljoints. For proper jointtreatment, maintainuniform room temperaturebetween 50˚F and 70˚Fduring cold weather. Treatjoints of face layer withtape and joint compound.

CAULKINGCaulk Cavity Shaftwall system

with acoustical sealantwherever the wall isenclosing shafts wherepositive or negative airpressure exists. Caulkperimeter of wall and atany other place wherevoids create the possibilityof moving air causing dustaccumulation, noise orsmoke leakage. Caulkingshall be done incompliance with detailsspecified by thearchitect/designer.

AIR SHAFTSThe System is not designed to

serve as an unlined airsupply duct. Caulking isrecommended atperimeters and penetrationswherever the I-Stud Systemis used to enclose elevatorsor other shafts wherepositive or negativepressures will exist. Thecontractor installing thisSystem shall caulk incompliance with detailsspecified by the architect/designer. Proper caulkingwill seal perimeters andpenetrations to minimizeair noises and dustassociated with airmovement.

FRAMING FOR OPENINGSFrame doors and duct

openings with J Track. Use adequate structuralsupport for openings over48" wide. For openings upto 48" wide, use vertical JTrack on either side ofopenings. For head and sillof openings, place J Trackhorizontally acrossopenings. Cut J Track about12" longer than openings.Then cut flanges and foldback to nest over vertical J Track and fasten webs orflanges with two 3/8" TypeS or 1/2" Type S-12 PanHead Screws perconnection. When nesting J Track to J Track, cut offshort flange of horizontal J Track so it will fit oververtical J Track.

CALL BOXES ANDPOSITION INDICATORSProtect call boxes, position

indicators and fireman’sswitches as shown indrawings on page 130.

CHASESWhen possible, locate all

vertical rise, conduit, stairhangers, etc., within wallcavity. If the cavity in the 2 1/2" stud wall is not ofsufficient width, the 4" or 6" studs can be used forchases or erect chase wallsas shown on page 134.

ELEVATOR DOORSElevator door frames must be

braced and supportedindependently of the

shaftwall. However,shaftwall must be tied intoelevator door frames bybeing attached to jamb andanchor clips with pan headscrews. The 3" leg, nominal20 gauge J Track shall beused at the juncture of theelevator door frame and theCavity Shaftwall System. Seedrawings on pages 128 and129 for details.

Door frames (other thanelevator door frames) shouldbe formed from not lessthan 18 gauge steel, shopprimed, with throatopenings accurately formedto the nominal wallthickness plus 3/32". Framesmust have trim returns notless than 7/16" in width tobear flush against thegypsum board surface. Flooranchor plates should be 14gauge (min.) steel, firmlywelded to frames anddesigned with not less thantwo anchor holes 3" o.c.minimum to prevent framerotation. Anchor platesshould be securely fastenedto the floor with powerdriven fasteners havingminimum dimensions of3/16" diameter and 3/4"length. The type and size offastener is dependent on jobconditions, type of concreteor steel framing, etc., andmust be sufficient to providerigid, continuous anchorageto the frames. Jamb anchorclips should be formed from18 gauge (min.) steel, andwelded to jambs to provideadequate anchorage to jambframing as shown on details.Elevator door frames mustbe fastened to andsupported by the buildingstructure, separately framedand independent of thepartition. They shall besecurely anchored to thesills and to the buildingstructure or to the tracksupports. Anchors orfastenings to suit the wallconstruction are requiredand shall be not more than2' apart. See details onpages 128 and 129 forconnection of partition andelevator door frames.

DESCRIPTION

SOLID TYPE AREASEPARATION WALLThe H-Stud Area Separation

Wall consists of 2" light-gauge steel H-Studs whichsecure two layers of 1" Fire-Shield Shaftliner or 1" Fire-Shield Shaftliner XP boardbetween adjacent studs.

Shaftliner board is faced withgreen moisture-resistantpaper and Shaftliner XPboard is faced with purplemoisture/mold/mildew-resistant paper on bothsides for protection againstweather during installation.Shaftliner panels have abeveled edge configurationallowing for simpleinstallation into the H-Studs.

The H-Studs are secured at thefoundation floor by theflanges of H-Stud Track.The same track is usedback-to-back atintermediate floors toprovide a splicing meansso that the System can beerected one floor at a time.H-Stud Track is also used atthe roof line or at theparapet and at wall ends.

For a fire-rated assemblywithout the need forbattens, a minimum 3/4"air space shall bemaintained between the H-Stud assembly and

Steel framing and XPGypsum Board productspermit temporary exposureto inclement weatherduring construction, butthe constructed AreaSeparation Wall should beprotected from inclementweather as soon aspossible. Materialssupplied to the job siteshould be stored properly,supported off the groundand protected frominclement weather.

TECHNICAL DATA

RECOMMENDATION

*When a 3/4" air space cannot be maintained between the H-Stud assembly and adjacent framing members, 1/2" Fire-Shield C Gypsum battens arerequired to cover H-Studs and H-Stud Track.

Order H-Studs and 1" Fire-Shield Shaftlineraccording to the followingoutline:

Basement wall section –length equal to distancefrom foundation floor toapproximately 3" abovefloor line of first floor.

Intermediate floors – lengthequal to distance betweenfloor lines.

Topmost floor – length toextend to top of parapetwall or to roof inter-section, depending on detail.

BASEMENT WALLINSTALLATION1. Beginning at foundation

floor, attach 2" H-StudTrack to concrete withpower-driven fastenersspaced 24" o.c. Applyacoustical sealant alongedges of track at floor line.

2. Install H-Stud Track onfoundation walls whereArea Separation Wallintersects, if applicable.Fasten with power-drivenfasteners 24" o.c. Caulkedges as with floor track.

3. At intersection offoundation or exterior walland Area Separation Wallbegin erecting by insertingfirst layer of 1" Shaftlinerinto floor and wall track.Insert second layer back-to-back with first and seatinto floor and wall track.Shaftliner and studs may

be set into position fromthe basement floor or feddown through the spaceprovided in the woodframing from the floorabove.

4. Making sure that bothpieces of Shaftliner areseated all the way into thefloor and wall tracks andthat their edges are flush,insert an H-Stud into thefloor track and engage theH-Stud legs over the longedges of the Shaftlinerboards. Seat the H-Studfully so the board edgescontact the stud web.

5. Continue in this manner,erecting two thicknessesof Shaftliner, and installingthe legs of the H-Stud overthe Shaftliner edges untilwall is completed. Again,make sure all studs andboards are tightly pushedtogether. Floor track maybe screw fastened to H-Studs with 3/8" Type Span head screws to assistwith installation.

6. If the Area SeparationWall terminates at afoundation wall, the lasttwo Shaftliner boards willhave to be inserted fromthe floor above. Boardsare pushed down into thechannel formed by theprevious H-Stud’s legs andthe legs of the wall track.

7. If the Area SeparationWall terminates at or pasta framed wall, insert thelast boards conventionallyand cap the end of theArea Separation Wall with

2" H-Stud Track. Fasten H-Stud track flanges at allcorners on both sides with3/8" Type S pan headscrews.

8. The top edge of theerected wall is thencapped off by placing 2"H-Stud Track over studsand boards. Track may bescrew fastened to H-Studswith 3/8" Type S pan headscrews to assist withinstallation.

9. Attach studs to adjacentwood framing with ASWClips. Secure the clips tothe studs with one 3/8"Type S Pan Head Screwthrough the short leg ofthe clip. The ASW Clipsmay be attached directlyto the steel studs orthrough the gypsum boardbatten face into the studs.

10. A minimum 3/4" air spaceshall be maintainedbetween the H-Studassembly and anyadjacent framingmembers.* When a 3/4" air space cannot bemaintained, gypsum boardbatten strips are installedover H-Studs and H-StudTrack on both sides of thewall. 3" wide battens areinstalled over H-StudTrack at foundation androof. 6" battens are screw-attached to H-Studs with1" Type S screws spaced12" o.c. screwed intoalternate legs of H-Stud.Battens are cut from sheetsof 1/2" Fire-Shield CGypsum Board.

INTERMEDIATE FLOORSAND ROOF INSTALLATION1. Attach 2" H-Stud Track to

the already installedcapping track of the lowerfloor’s wall. This back-to-back track installationallows the Area SeparationWall to be erected onefloor at a time. Secure thetwo tracks together withtwo 3/8" Type S pan headScrews 24" o.c. Staggerback-to-back track joints a minimum of 12".

2. Erect Shaftliner and H-Studsin the same manner as forthe basement wall, steps 4-10, except that starting andending procedures varydepending on the exteriorwall intersection detail. Seedrawing details.

3. At roof intersection thewalls are capped-off withH-Stud track. Track may befastened to H-Stud with3/8" Type S pan headscrews to assist withinstallation. H-Studs arefastened to wood framingwith ASW Clips. Thespecific framing procedurevaries according to roofjunction drawing details.

4. Fire blocking must beprovided at intermediatefloors and roof locations asshown in drawing details.Mineral wool or gypsumboard filler may be used.

An ideal substrate for exteriorapplications such as:

� Tile applications

� Stucco applications

� Countertops

� Soffit panels

� Sheathing panels

� Decks

� Outdoor kitchens/grills

GENERAL: All framing should comply with local buildingcode requirements and bedesigned to provide supportwith a maximum allowabledeflection of L/360 under allintended live (including wind)and dead loads.Note: Cut or score PermaBaseon rough side of panel. Installtile and tile setting materials inaccordance with current ANSIspecifications and Tile Councilof America (TCA) guidelines.CONTROL JOINTS: For exteriorinstallations, allow a maximumof 16 lineal feet between controljoints. (For exterior tile applica-tions, control joints should bespaced a maximum of every12'.) A control joint must beinstalled but not limited to the following locations: whereexpansion joints occur in theframing or building (discontinueall cross furring members locatedbehind joint); when boards abutdissimilar materials; where fram-ing material changes; at changesof building shape or structuralsystem; at each story separation.Place control joints at corners ofwindow and door openings, orfollow specifications of architect.Control joint cavity shall not befilled with coating or othermaterials.DECKSSUBFLOOR: Plywood shouldbe securely glued and fastenedto floor joists spaced a maxi-mum of 16" o.c. Subfloorshould be sloped at a mini-mum pitch of 1/4" per foot. Thefloor surface should be true toplane within 1/8" in 10'.

UNDERLAYMENT: Using a 1/4"square-notched trowel, apply a setting bed of latex-Portlandcement mortar to the subfloor.Immediately laminatePermaBase to subfloor, leaving a1/8" space between boards at alljoints and corners. Leave a 1/4"gap along walls. Stagger all jointsso they do not line up withunderlying substrate joints.Fasten PermaBase every 8" o.c.throughout board field andaround all edges while settingbed mortar is still workable.Around the perimeter of eachboard, locate fasteners 2" fromthe corners and not less than3/8" from the edges. Fill all jointssolid with bonding material. On non-tapered joints such as buttends, apply a 6" wide, 1/16"thick coat over the entire joint.For all joints, immediatelyembed alkali resistant fiberglassmesh tape fully into appliedbonding material; ensure thattape is centered over joint. Applybonding material over fastenersto fully conceal. Remove allexcess bonding material andallow to cure.WATERPROOF MEMBRANE:Trowel apply waterproof mem-brane to the entire surface ofthe PermaBase, followingmembrane manufacturer’sinstallation instructions indetail.

WALLS & CEILINGSWALL FRAMING: Studsshould be spaced a maximumof 16" o.c. Edges/ends ofPermaBase parallel to framingshould be continuously sup-ported. Provide additionalblocking when necessary topermit proper PermaBaseattachment. Do not installPermaBase directly over pro-trusions from stud plane suchas heavy brackets or fastenerheads.CEILING FRAMING: Thedeflection of the complete ceil-ing assembly due to dead load(including insulation,PermaBase, bonding materialand facing material) should notexceed L/360. The dead loadapplied to the ceiling frameshould not exceed 10 psf.Ceiling joist or furring channelshould not exceed 16" o.c.(Edges of PermaBase parallel toframing should be continuous-ly supported.) Provide addition-al blocking when necessary topermit proper PermaBaseattachment.

EXTERIOR APPLICATIONS

WEATHER BARRIER: WhilePermaBase is unaffected by moisture, a water barrier mustbe installed to protect the cavi-ty. It should be installedaccording to the manufacturer’sspecifications.PERMABASE CEMENTBOARD: Apply PermaBasewith ends and edges closelybutted but not forced together.Stagger end joints in successivecourses.

APPLICATIONS

INSTALLATION


Cement Board Stucco is awater-managed exterior wallsystem designed to provideincreased high-impact andweather resistance andimproved dimensional stabilitywhere exterior insulation valueis not required. For the purpos-es of meeting structural rackingor fire code requirements, it isapplied over the followingapproved sheathings: Exposure1 or exterior plywood (grade C-D or better); Exposure 1 OSB;glass mat gypsum substratemeeting ASTM C 1177; orwater resistant core gypsum(ASTM C 1396).It combines the strength anddurability of PermaBase CementBoard with the performanceand beauty of reinforced basecoats and textured finishes. Allfinishes are available in a limit-less color selection and offer performance enhance-ment options ranging fromextra mildew resistance toadded flexibility.Behind the system, a weather-resistant barrier complyingwith ASTM D-226 protectsapproved sheathings and otherstructural components andserves as a component to evac-uate incidental water. CementBoard Stucco allows you toenclose and finish a project inas little as two days, speedingoccupancy.

For high-impact and weather-resistant exterior wall in resi-dential and low-rise commer-cial applications.

DURABILITY/STRENGTH:Moisture resistant, durablePermaBase Cement Board sub-strates applied over a primarysheathing provide extraordi-nary impact and punctureresistance to the system.WEATHER RESISTANCE:100% Acrylic base coats andfinishes repel weather at thesystem’s surface.WATER-MANAGED DESIGN:The water-managed design ofthe system provides drainage tothe exterior of incidental waterthat might enter around orthrough window or door open-ings and penetrate behind thecladding in frame construction.

WATER-MANAGED, HIGH-IMPACT RESISTANT WALL SYSTEM

DESIGN OPTIONS:Cement Board Stucco providesthe popular stucco look,including the attachment ofspecial pre-molded shapes anda wide variety of finish textureand color options in standardcolors and custom colors.Contact exterior coatings manufacturer for color and installation instructions.

� Use is limited to residentialand low-rise commercialapplications.

� Thin veneer construction willtend to reveal planar irregu-larities in the frame construc-tion.

� Minor cracking at jointsmight become visible in thefinished exterior surface.

� For exterior finishes applieddirect to PermaBase, rein-forcing mesh must beembedded in basecoat.Consult exterior manufac-turer for additional installa-tion requirements.

� For conventional PortlandCement plaster systems, self-furring metal lath must be used over PermaBaseand adhered to studs.
