Seal tops, bottoms, and cutouts of unprimed wood doors with a heavy coat of varnish or sealer immediately upon delivery. 6. Ferrous Metals: Clean ungalvanized ferrous metal surfaces that have not been shop-coated; remove oil, grease, dirt, loose mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that comply with recommendations of the Steel Structures Painting Council (SSPC). a. Blast steel surfaces clean as recommended by the paint system manufacturer and according to requirements of SSPC specification SSPC-SP 10. b. Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming. c. Touch up bare areas and shop-applied prime coats that have been damaged. Wire-brush, clean with solvents recommended by the paint manufacturer, and touch up with the same primer as the shop coat. 7. Galvanized Surfaces: Clean galvanized surfaces with nonpetroleum-based solvents so that the surface is free of oil and surface contaminants. Remove pretreatment from galvanized sheet metal fabricated from coil stock by mechanical methods. 3.3 PREPARATION OF EXISTING SURFACES A. Existing Painted Gypsum Board: Touch up all holes, dents, etc with drywall patching components approved by the paint manufacturer for the intended purpose. Scrape all loose paint off. Sand and taper smooth all rough spots and blemishes. Provide same number of finish c B. Existing Ferrous Metals to Remain: Grind and sand all loose and peeling paint. Sand and feather all edges smooth. Prime bare metal before painting C. Materials Preparation: Carefully mix and prepare paint materials according to manufacturer’s directions. 1. Maintain containers used in mixing and applying paint in a clean condition, free of foreign materials and residue. 2. Stir material before application to produce a mixture of uniform density; stir as required during application. Do not stir surface film into material. Remove film and, if necessary, strain material before using. 3. Use only thinners approved by the paint manufacturer and only within recommended limits. D. Tinting: Tint each undercoat a lighter shade to facilitate identification of each coat where multiple coats of the same material are applied. Tint undercoats to match the color of the finish coat but provide sufficient differences in shade of undercoats to distinguish each separate coat. 3.4 APPLICATION A. General: Apply paint according to manufacturer’s directions. Use applicators and techniques best suited for substrate and type of material being applied. 1. Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to formation of a durable paint film. 2. Paint colors, surface treatments, and finishes are indicated in the schedules. 3. Provide finish coats that are compatible with primers used. 4. The number of coats and the film thickness required are the same regardless of the application method. Do not apply succeeding coats until the previous coat has cured as recommended by the manufacturer. Sand between applications where sanding is required to produce a smooth even surface according to the manufacturer’s directions. 5. Apply additional coats if 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 ensure that surfaces, including edges, corners, crevices, welds, and exposed fasteners, receive a dry film thickness equivalent to that of flat surfaces. 6. The term exposed surfaces includes areas visible when permanent or built-in fixtures, convector covers, covers for finned tube radiation, grilles, and similar components are in place.
