<br />A. Comply with procedures specified in PDCA P4 for inspection and acceptance of surfaces to be painted.
<br />B. Coordination of Work: Review other Sections in which primers are provided to ensure compatibility of the total system for various
<br />substrates. On request, furnish information on characteristics of finish materials to ensure use of compatible primers.
<br />C. Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and similar items already installed that
<br />are not to be painted. If removal is impractical or impossible because of size or weight of the item, provide surface -applied protec-
<br />tion before surface preparation and painting.
<br />1. After completing painting operations in each space or area, reinstall items removed using workers skilled in the trades
<br />involved.
<br />D. Surface Preparation: Clean and prepare surfaces to be painted according to manufacturer's written instructions for each particular
<br />substrate condition and as specified.
<br />1. Provide barrier coats over incompatible primers or remove and reprime.
<br />2. Cementitious Materials: Remove efflorescence, chalk, dust, dirt, grease, oils, and release agents. Roughen as required to
<br />remove glaze. If hardeners or sealers have been used to improve curing, use mechanical methods of surface preparation.
<br />3. Wood: Clean surfaces of dirt, oil, and other foreign substances with scrapers, mineral spirits, and sandpaper, as required.
<br />Sand surfaces exposed to view smooth and dust off.
<br />a. Scrape and clean small, dry, seasoned knots, and apply a thin coat of white shellac or other recommended knot sealer
<br />before applying primer. After priming, fill holes and imperfections in finish surfaces with putty or plastic wood filler.
<br />Sand smooth when dried.
<br />b. Prime, stain, or seal wood to be painted immediately on delivery. Prime edges, ends, faces, undersides, and back sides
<br />of wood, including cabinets, counters, cases, and paneling.
<br />C. If transparent finish is required, backprime with spar varnish.
<br />d. Backprime paneling on interior partitions where masonry, plaster, or other wet wall construction occurs on back
<br />side.
<br />e. Seal tops, bottoms, and cutouts of unprimed wood doors with a heavy coat of varnish or sealer immediately on deliv-
<br />ery.
<br />4. Ferrous Metals: Clean ungalvanized ferrous -metal surfaces that have not been shop coated; remove oil, grease, dirt, loose
<br />mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that comply with SSPC's recommen-
<br />dations.
<br />a. Blast steel surfaces clean as recommended by paint system manufacturer and according to SSPC-SP 6/NACE No. 3.
<br />b. Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming.

<br />mended by paint manufacturer, and touch up with same primer as the shop coat.
<br />5. Galvanized Surfaces: Clean galvanized surfaces with nonpetroleum-based solvents so surface is free of oil and surface
<br />contaminants. Remove pretreatment from galvanized sheet metal fabricated from coil stock by mechanical methods.
<br />E. Material Preparation:
<br />1. Maintain containers used in mixing and applying paint in a clean condition, free of foreign materials and residue.

<br />surface film into material. If necessary, remove surface film and strain material before using.
<br />F. Exposed Surfaces: Include areas visible when permanent or built-in fixtures, grilles, convector covers, covers for finned -tube
<br />radiation, and similar components are in place. Extend coatings in these areas, as required, to maintain system integrity and pro-
<br />vide desired protection.

<br />equipment, paint surfaces behind permanently fixed equipment or furniture with prime coat only.
<br />2. Paint interior surfaces of ducts with a flat, nonspecular black paint where visible through registers or grilles.
<br />3. Paint back sides of access panels and removable or hinged covers to match exposed surfaces.

<br />practicable after preparation and before subsequent surface deterioration.
<br />1. Omit primer over metal surfaces that have been shop primed and touchup painted.
<br />2. If undercoats, stains, or other conditions show through final coat of paint, apply additional coats until paint film is of uniform
<br />finish, color, and appearance.
<br />I. Application Procedures: Apply paints and coatings by brush, roller, spray, or other applicators according to manufacturer's written
<br />instructions.
<br />J. Minimum Coating Thickness: Apply paint materials no thinner than manufacturer's recommended spreading rate. Provide total
<br />dry film thickness of the entire system as recommended by manufacturer.
<br />K. Mechanical and Electrical Work: Painting of mechanical and electrical work is limited to items exposed in equipment rooms and
<br />occupied spaces.
<br />L. Block Fillers: Apply block fillers to concrete masonry block at a rate to ensure complete coverage with pores filled.
<br />M. Prime Coats: Before applying finish coats, apply a prime coat, as recommended by manufacturer, to material that is required to
<br />be painted or finished and that has not been prime coated by others. Recoat primed and sealed surfaces where evidence of suction
<br />spots or unsealed areas in first coat appears, to ensure a finish coat with no burn -through or other defects due to insufficient seal-
<br />ing.
<br />N. Pigmented (Opaque) Finishes: Completely cover surfaces as necessary to provide a smooth, opaque surface of uniform finish,
<br />color, appearance, and coverage. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfec-
<br />tions will not be acceptable.
<br />0. Transparent (Clear) Finishes: Use multiple coats to produce a glass -smooth surface film of even luster. Provide a finish free of
<br />laps, runs, cloudiness, color irregularity, brush marks, orange peel, nail holes, or other surface imperfections.
<br />P. Stipple Enamel Finish: Roll and redistribute paint to an even and fine texture. Leave no evidence of rolling, such as laps, irregular-
<br />ity in texture, skid marks, or other surface imperfections.
