3.1 PREPARATION

A. Cover and protect finished work and surfaces not to be painted. Use drop cloths of adequate size to protect adjacent areas.

B. Remove hardware, hardware accessories, machined surfaces, plates, lighting fixtures, and similar items in place and not to be painted, or provide surface applied protection. Reinstall removed items when final coat is thoroughly dry.

C. All surfaces to receive paint shall be thoroughly cleaned and prepared to allow proper adhesion of new paint. Do not paint over dirt, rust, scale, grease, moisture, voids and blemishes, or other conditions detrimental to formation of a durable paint film.

D. Mix and prepare painting materials in accordance with manufacturer's directions.

Rev. Date 5/20/19 Perks Rehabilitation 099010-3/4 Painting

E. Apply paint in accordance with manufacturer's directions. Use techniques best suited for substrate and type of material being applied.

3.1 PREPARATION AND FINISHING OF EXTERIOR AND INTERIOR WOOD

A. Preparation:

1. Remove dust by brushing and remove grease and oil by washing with mineral spirits or other solvent. Remove sap on wood surfaces by scraping and washing with turpentine. Sand all interior wood before priming.

2. Seal all knots or resinous areas with knot sealer and allow to dry at least 2 hours before priming. Fill all gouges, dents, and small openings in interior wood with plastic wood tinted for stained or natural appearance. Allow plastic wood to dry before painting.

3. Back prime backs, edges, and ends of interior and exterior wood.

3.2 APPLICATION

A. Follow manufacturer’s directions and apply material evenly without runs, sags, or other defects. Leave moldings, trim, ornaments, edges, and millwork clean and true to details without excess paint in corners or depressions. Make edges of paint adjoining other materials or colors sharp and clean, without overlaps.

B. Paint surfaces behind movable equipment and furniture same as similar exposed surfaces. Paint surfaces behind permanently-fixed equipment or furniture with prime coat only.

C. Finish access panels, grilles, registers, and similar items in the same color as their surroundings.

D. Finish exterior doors on tops, bottoms, and side edges same as exterior faces.

E. Apply materials at not less than manufacturer's recommended spreading rate, to establish a total dry film thickness as recommended by the manufacturer.

F. Drying Time: Minimum time recommended by manufacturer. Do not apply succeeding coats until the undercoat is thoroughly dry.

G. Sanding: Lightly sand between coats to ensure that surface finish is smooth to the touch. Exterior stained siding, soffits, fascia, and rough-sawn material need not be sanded.

H. Apply additional coats when undercoats, stains, or other conditions show through final coat of paint. Final finish shall have uniform color and appearance.

3.3 CLEANING

A. Do not allow accumulation of empty containers or other excess items except in areas set aside for that purpose.

B. Remove all paint, stain, or other finish material where it has spilled or spattered.

C. Remove all new and old paint, or other finish material from window glass and clean windows.

1.03 OWNER’S INSTRUCTIONS

A. Conform to the dimensions and elevations indicated on the Drawings. Suitable bearing may be encountered at different elevations from those on the Drawings. If so, the COR may direct, by written order, that the excavation elevations be changed to the elevation where suitable bearing was encountered. Extend excavation a sufficient distance from walls and footings to allow placing and removal of forms.

Undercutting will not be permitted. Prevent surface water from entering the excavation.
