3.03 PAINTING

A. Surface Preparation:

1. General:

b. Remove incompatible primers and reprime substrate with compatible primers or apply tie coat as required to produce paint systems indicated.

2. Ferrous Metal Substrates:

a. Remove rust, loose mill scale, and shop primer if any. Clean using methods recommended in writing by paint manufacturer.

1) Begin with SSPC-SP2 - Hand Tool Cleaning method first.

2) If needed use SSPC-SP3 - Power Tool Cleaning method. Obtain Architect's written approval first.

3. Wood Substrates:

a. Remove obsolete nails and screws from wood.

b. Remove loose or flaking paint. Sand all bare wood surfaces and feather edges of sound coatings to provide smooth transition between coated and uncoated surfaces.

c. Repair damaged and deteriorated wood per Section 06 01 40 - Repair and

Restoration of Architectural Woodwork.

d. Sand surfaces that will be exposed to view, and dust off.

e. Treat bare wood with wood preservative.

f. Fill holes and imperfections in finish surfaces with wood filler. Sand smooth when dried. See Section 06 01 40 - Repair and Restoration of Architectural Woodwork.

09 90 00 - 6 Painting and Coating

D. Application

1. Apply paints according to manufacturer's written instructions and recommendations in

"MPI Manual".

a. Use applicators and techniques suited for paint and substrate indicated.

2. Tint undercoats same color as finish coat, but tint each undercoat lighter shade to facilitate identification of each coat if multiple coats of same material are to be applied. Provide sufficient difference in shade of undercoats to distinguish each separate coat.

3. If undercoats or other conditions show through finish coat, apply additional coats until cured film has uniform paint finish, color, and appearance. Give special attention to edges, corners, crevices, welds, exposed fasteners, and similar surfaces to ensure that they receive dry film thickness equivalent to that of flat surfaces.

4. Number of coats and film thickness required is same regardless of application method. Do not apply succeeding coats until previous coat has cured as recommended by manufacturer. Where sanding is required, according to manufacturer's directions, sand between applications to produce smooth, even surface.

a. Number of coats specified for paint systems in Paint Schedule is minimum. Provide additional coats as necessary to provide durable coating complying with application and appearance requirements.

5. Apply each material no thinner than manufacturer's recommended spreading rate unless otherwise stated in this Section. Provide total dry film thickness of entire system as recommended by manufacturer or as otherwise indicated.

6. Application Procedures: Apply coatings by brush, roller, spray, or other applicators according to manufacturer's directions.

a. Brushes: Use brushes best suited for material applied.

b. Rollers: Use rollers of carpet, velvet back, or high-pile sheep's wool as recommended by manufacturer for material and texture required.

c. Spray Equipment: Use spray equipment with orifice size as recommended by manufacturer for material and texture required.

7. Apply material evenly without runs, sags, or other defects. Work each coat into material being coated at average rate of coverage recommended. Cover surfaces completely to provide uniform color and appearance. Make edges of paint adjoining other materials or colors sharp and clean, and without overlaps.

8. Do not apply paints over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to forming durable paint film.

9. Do not apply paint over mortar joints or sealant.

10. Apply paints to produce surface films without cloudiness, spotting, holidays, laps, brush marks, roller tracking, runs, sags, ropiness, or other surface imperfections. Cut in sharp lines and color breaks.

11. 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.

a. Allow sufficient drying time between successive coats. Do not recoat until paint has dried so it feels firm and does not deform or feel sticky under moderate thumb pressure and where applying another coat does not cause undercoat to lift or lose adhesion.

E. Field Quality Control:

1. Dry Film Thickness Testing: Owner may engage services of qualified testing and inspecting agency to inspect and test paint for dry film thickness.

a. Contractor shall touch up and restore painted surfaces damaged by testing.

b. If test results show that dry film thickness of applied paint does not comply with paint manufacturer's written recommendations, Contractor shall pay for testing and apply additional coats as needed to provide dry film thickness that complies with paint manufacturer's written recommendations.
