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. 4. 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.
5. Omit primer on metal surfaces that have been shop-primed and touch-up painted.
C. Scheduling Painting: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for painting as soon as practicable after preparation and before subsequent surface deterioration.

pressure, and where application of another coat of paint does not cause the undercoat to lift or
lose adhesion. D. Application Procedures: Apply paints and coatings by brush, roller, spray, or other applicators according to the manufacturer’s directions.
1. Brushes: Use brushes best suited for the material applied.
2. Spray Equipment: Use airless spray equipment with orifice size as recommended by the
manufacturer for the material and texture required.
E. Minimum Coating Thickness: Apply materials no thinner than the manufacturer’s recommended spreading rate. Provide the total dry film thickness of the entire system as recommended by the manufacturer.
F. Prime Coats: Before applying finish coats, apply a prime coat of material, as recommended by the
manufacturer, to material that is required to be painted or finished and that has not been prime-coated by others. Recoat primed and sealed surfaces where evidence of suction spots or unsealed areas in first coat appears, to ensure a finish coat with no burn-through or other defects due to insufficient sealing.
