Remove all foreign material from joint substrates that could interfere withadhesion of joint sealant, including dust, paints (except for permanent,protective coatings tested and approved for sealant adhesion and compatibilityby sealant manufacturer), old joint sealants, oil, grease, waterproofing, waterrepellents, water, surface dirt, and frost.

2. Clean porous joint substrate surfaces by brushing, grinding, blast cleaning,mechanical abrading, or a combination of these methods to produce a clean,sound substrate capable of developing optimum bond with joint sealants.Remove loose particles remaining from above cleaning operations byvacuuming or blowing out joints with oil-free compressed air. Porous jointsurfaces include the following:

a. Concrete.b. Masonry.c. Unglazed surfaces of ceramic tile.

3. Remove laitance and form-release agents from concrete.


4. Clean nonporous surfaces with chemical cleaners or other means that do notstain, harm substrates, or leave residues capable of interfering with adhesion ofjoint sealants.

a. Metal.b. Glass.c. Glazed surfaces of ceramic tile.

B. Joint Priming: Prime joint substrates where recommended in writing by joint sealantmanufacturer, based on preconstruction joint-sealant-substrate tests or priorexperience. Apply primer to comply with joint sealant manufacturer's writteninstructions. Confine primers to areas of joint-sealant bond; do not allow spillage ormigration onto adjoining surfaces.

C. Masking Tape: Use masking tape where required to prevent contact of sealant withadjoining surfaces that otherwise would be permanently stained or damaged by suchcontact or by cleaning methods required to remove sealant smears. Remove tapeimmediately after tooling without disturbing joint seal.

3.3 INSTALLATION OF JOINT SEALANTS

A .General: Comply with joint sealant manufacturer's written installation instructions forproducts and applications indicated, unless more stringent requirements apply.

B .Sealant Installation Standard: Comply with recommendations of ASTM C 1193 foruse of joint sealants as applicable to materials, applications, and conditions indicated.

C. Acoustical Sealant Application Standard: Comply with recommendations ofASTM C 919 for use of joint sealants in acoustical applications as applicable tomaterials, applications, and conditions indicated.

D. Install sealant backings of type indicated to support sealants during application and atposition required to produce cross-sectional shapes and depths of installed sealantsrelative to joint widths that allow optimum sealant movement capability.

1. Do not leave gaps between ends of sealant backings.2. Do not stretch, twist, puncture, or tear sealant backings.3. Remove absorbent sealant backings that have become wet before sealant

application and replace them with dry materials.

E. Install bond-breaker tape behind sealants where sealant backings are not usedbetween sealants and back of joints.

F. Install sealants by proven techniques to comply with the following and at the sametime backings are installed:

1. Place sealants so they directly contact and fully wet joint substrates.2. Completely fill recesses provided for each joint configuration.


3. Produce uniform, cross-sectional shapes and depths relative to joint widths thatallow optimum sealant movement capability.

G. Tooling of Nonsag Sealants: Immediately after sealant application and beforeskinning or curing begins, tool sealants according to requirements specified below toform smooth, uniform beads of configuration indicated; to eliminate air pockets; andto ensure contact and adhesion of sealant with sides of joint.

1. Remove excess sealants from surfaces adjacent to joint.2. Use tooling agents that are approved in writing by sealant manufacturer and

that do not discolor sealants or adjacent surfaces.3. Provide concave joint configuration per Figure 5A in ASTM C 1193, unless

otherwise indicated.

3.4 CLEANING

A. Clean off excess sealants or sealant smears adjacent to joints as the Workprogresses by methods and with cleaning materials approved in writing bymanufacturers of joint sealants and of products in which joints occur.

356 PROTECTION

A. Protect joint sealants during and after curing period from contact with contaminatingsubstances and from damage resulting from construction operations or other causesso sealants are without deterioration or damage at time of Substantial Completion. If,despite such protection, damage or deterioration occurs, cut out and removedamaged or deteriorated joint sealants immediately so installations with repairedareas are indistinguishable from the original work.
