<br />sides 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 />C. Touch up bare areas and shop -applied prime coats that have been damaged. Wire -brush, clean with solvents recom-
<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 />2. Stir material before application to produce a mixture of uniform density. Stir as required during application. Do not stir
<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 />1. Paint surfaces behind movable equipment and furniture the same as similar exposed surfaces. Before final installation of
<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 />4. Finish exterior doors on tops, bottoms, and side edges the same as exterior faces.
<br />5. Finish interior of wall and base cabinets and similar field -finished casework to match exterior.
<br />G. Sand lightly between each succeeding enamel or varnish coat.
<br />H. Scheduling Painting: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for painting as soon as
<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.
