3.2 SUBSTRATE

A. PREPARATION

1. Mask and protect all materials and surfaces that could potentially be sensitive to chlorine bleach solution.

2. Cover or mask any openings, holes or damaged areas to prevent water or

cleaning solution from entering the wall cavity.

solution. Spray pressures must never exceed 300 psi. 3. If the wall is warm or if working in the sun in warm weather, wet the wall with

clear water. 4. Starting at the top of a wall area, apply cleaning solution to the wall with a low-

pressure spray or stream. Use horizontal sweeps to apply the cleaning solution. Keep a six to twelve inch run-down of cleaning solution on the wall surface below the stream. Adjust the spray or stream to avoid excessive misting and bounce-back of the cleaning solution.

5. Treat entire vertical sections of wall area before moving to the next area. 6. Allow the WATER to have three to five minutes of contact time with the wall

surface. Thoroughly rinse the wall surface beginning at the top with a clear water spray.

3.3 RE-APPLICATION

A. Wall areas may be re-cleaned one additional time, if necessary, following the above procedure to achieve a more thorough result. This will be determined by visual inspection after the first cleaning a permitting sufficient time for the wall area to dry.

3.4 JOB SITE CLEANUP

A. All excess materials, tarps, equipment and masking shall be removed from the job site by the applicator.

3.2 PREPARATION

A. Do not start work until surfaces to be finished are in proper condition to produce finished surfaces of uniform, satisfactory appearance.

B. Clean surfaces thoroughly prior to coating application. C. Stains and Marks: Remove completely, if possible, using materials and methods

recommended by coating manufacturer; seal with shellac or other coating acceptable to paint manufacturer stains and marks that might bleed through paint finishes which cannot be completely removed.

D. Remove or protect hardware, electrical plates, mechanical grilles and louvers, lighting

fixture trim, and other items not indicated to receive coatings which are adjacent to surfaces to receive coatings.

E. Remove mildew from impervious surfaces by scrubbing with solution of trisodium

phosphate and bleach. Rinse with clean water and allow substrate to thoroughly dry.

H. Metals - Ferrous, Unprimed: Remove rust or scale, if present, by wire brush cleaning, power tool cleaning, or sandblast cleaning; remove grease, oil, and other contaminants which could impair coating performance or appearance by solvent cleaning, with phosphoric-acid solution cleaning of welds, bolts and nuts; spot-prime repaired welds with specified primer.

I. Metals - Ferrous, Shop-Primed: Remove loose primer and rust, if present, by scraping and sanding, feathering edges of cleaned areas to produce uniform flat surface; solvent-clean surfaces and spot-prime bare metal with specified primer, feathering edges to produce uniform flat surface.

J. Metals - Galvanized Steel (not passivated): Clean with a water-based industrial strength cleaner, apply an adhesion promoter followed by a clean water rinse. Alternately, wipe down surfaces using clean, lint-free cloths saturated with xylene or lacquer thinner; followed by wiping the surface dry using clean, lint-free cloths.

K. Metals - Galvanized Steel, Passivated: Clean with water-based industrial strength cleaner. After the surface has been prepared, apply recommended primer to a small area. Allow primer to cure for 7 days, and test adhesion using the "cross-hatch adhesion tape test" method in accordance with ASTM D 3359. If the adhesion of the primer is positive, proceed with a recommended coating system for galvanized metal.

L. Metals - Stainless Steel: Clean surfaces with pressurized steam, pressurized water, or water-based industrial cleaner.

M. Plaster: Repair cracks, holes and other surface defects as required to maintain proper surface adhesion. Apply patching plaster or Joint compound and sand to produce surface flush with adjacent undamaged surface. Allow a full cure prior to coating application as recommended by the patching compound manufacturer's recommendations.

N. Polyvinyl Chloride (PVC) Pipe: remove contaminants and markings with denatured alcohol scuff sand and wipe with solvent for maximum adhesion. Test adhesion before starting the job.

O. Fiberglass Doors - remove contaminants with cleaning solvent (alcohol) scuff sand and wipe. Test adhesion of primer before starting job.

P. Textiles - Insulated Coverings, Canvas or Cotton: Clean using high-pressure air and solvent of type recommended for material.

3.4 APPLICATION

A. General:

A. Apply paint in accordance with manufacturer's directions. Use applicators and techniques best suited to substrate and type of material being applied. Do not use roller or spray for wood and plywood, or roller for metal, unless specifically approved by the Contracting Officer.

B. Apply additional coats when undercoats, stains or other conditions show through final

coat of paint, until paint film is of uniform finish, color and appearance. Give special attention to insure that surfaces, including edges, corners, crevices, welds, and exposed fasteners receive a dry film thickness equivalent to that of flat surfaces.

C. Paint surfaces behind movable equipment and furniture same as similar exposed

surfaces.

D. Paint back sides of access panels, and removable or hinged covers to match exposed surfaces.

E. Sand lightly between each succeeding enamel or varnish coat.

F. Omit first coat (primer) on metal surfaces which have been shop-primed and touch-up

painted, unless otherwise indicated. Spot prime any damaged areas. B. Scheduling Painting:

A. Apply first coat material to surfaces that have been cleaned, pretreated, or otherwise prepared for painting as soon as practicable after preparation and before subsequent surface deterioration.

B. Allow sufficient time between successive coatings to permit proper drying. Do not

recoat until paint has dried to where it feels firm, does not deform, or feel sticky under moderate thumb pressure, and application of another coat of paint does not cause lifting or loss of adhesion of the undercoat.

C. Minimum Coating Thickness:

A. Apply materials at not less than manufacturer's recommended spreading rate, to provide a dry film thickness per coat as indicated, or if not indicated, as recommended by coating manufacturer.

D. Mechanical and Electrical Work:

A. Mechanical items to be painted include, but are not limited to, the following (where present):

a. Piping and supports, roof vents, louvers, grilles, registers, fans and curbs.

B. Electrical items to be painted include, but are not limited to, the following (where present):

E. Prime Coats:

A. Apply prime coat to material which is required to be painted or finished, and which has not been prime coated by others.

B. Recoat primed and sealed surfaces where there is evidence of suction spots or

unsealed areas in first coat, to assure a finish coat with no burn-through or other defects due to insufficient sealing.

F. Pigmented (Opaque) Finishes:

A. Completely cover to provide an opaque, smooth surface of uniform finish, color, appearance and coverage. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections will not be acceptable. Cut in sharp lines and color breaks.

3.5 CLEANING

A. During progress of work, remove from site discarded paint materials, rubbish cans and rags at end of each work day.

B. Upon completion of painting work, clean window glass and other paint-spattered surfaces.

Remove spattered paint by proper method of washing and scraping, using care not to scratch or otherwise damage finished surfaces.

C. At the completion of work of other trades, touch-up and restore all damaged or defaced

painted surfaces.

D. Vacate space for as long as possible after application. Wait a minimum of 48 hours before occupying freshly painted rooms.

3.6 PROTECTION

A. Protect work of other trades against damage from paint application. Correct damage to work of other trades by cleaning, repairing, replacing, and refinishing, as approved by Contracting Officer, and leave in an undamaged condition.

B. Provide "Wet Paint" signs as required to protect newly painted finishes. Remove temporary

protective wrappings provided by others for protection of their work after completion of painting operations.

3.7 SURFACE PREPARATION
