Provide finish coats that are compatible with primers used. <br />4. The number of coats and the film thickness required are the same regardless of the application method. <br />Do not apply succeeding coats until the previous coat has cured as recommended by the manufacturer. <br />Sand between applications where sanding is required to produce a smooth even surface according to <br />the manufacturer’s directions. <br />5. Apply additional coats if undercoats, stains, or other conditions show through final coat of paint until <br />paint film is of uniform finish, color, and appearance. Give special attention to ensure that surfaces, <br />including edges, corners, crevices, welds, and exposed fasteners, receive a dry film thickness <br />equivalent to that of flat surfaces. <br />6. The term exposed surfaces includes areas visible when permanent or built-in fixtures, convector <br />covers, covers for finned tube radiation, grilles, and similar components are in place. Extend coatings <br />in these areas, as required, to maintain the system integrity and provide desired protection. <br />7. Paint surfaces behind movable equipment and furniture the same as similar exposed surfaces. Before <br />the final installation of equipment, paint surfaces behind permanently fixed equipment or furniture <br />with prime coat only. <br />8. Paint interior surfaces of ducts, where visible through registers or grilles, with a flat, non-specular <br />black paint. <br />9. Paint back sides of access panels and removable or hinged covers to match exposed surfaces. <br />10. Finish exterior doors on tops, bottoms, and side edges same as exterior faces. Sand lightly between <br />each succeeding enamel or varnish coat. Omit primer on metal surfaces that have been shop-primed <br />and touch-up painted. <br />B. Scheduling Painting: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for <br />painting as soon as practicable after preparation and before subsequent surface deterioration. <br />1. Allow sufficient time between successive coats to permit proper drying. Do not recoat until paint has <br />dried to where it feels firm, does not deform or feel sticky under moderate thumb pressure, and where <br />application of another coat of paint does not cause the undercoat to lift or lose adhesion. <br />3.5 PROCEDURES <br />A. Apply paints and coatings by brush, roller, spray, or other applicators according to the manufacturer’s <br />directions. <br />1. Brushes: Use brushes best suited for the material applied. <br />2. Rollers: Use rollers of carpet, velvet back, or high-pile sheep’s wool as recommended by the <br />manufacturer for the material and texture required. <br />3. Spray Equipment: Use airless spray equipment with orifice size as recommended by the manufacturer <br />for the material and texture required. <br />B. Minimum Coating Thickness: Apply materials no thinner than the manufacturer’s recommended spreading <br />rate. Provide the total dry film thickness of the entire system as recommended by the manufacturer. <br />C. Mechanical and Electrical Work: Painting mechanical and electrical work is limited to items exposed in <br />occupied spaces. <br />1. Mechanical items to be painted include, but are not limited to, the following: <br />a. Piping, pipe hangers, and supports. <br />b. Heat exchangers. <br />c. Tanks. <br />d. Ductwork. <br />e. Insulation. <br />f. Supports. <br />g. Accessory items. <br />2. Electrical items to be painted include, but are not limited to, the following: <br />a. Conduit and fittings, including hangers. <br />b. Switchgear. <br />D. Block Fillers: Apply block fillers to concrete masonry block at a rate to ensure complete coverage with pores <br />filled. <br />Docusign Envelope ID: 52FACC74-DA96-491B-B0B8-04AC3961737D
