PART 3 - EXECUTION

3.1 EXAMINATION

A. Examine substrates, areas, and conditions, with Applicator present, for compliance with requirements for coating application. Proceed with coating application only after unsatisfactory conditions have been corrected and surfaces receiving coatings are thoroughly dry.

B. Start of coating will be construed as Applicator’s acceptance of surfaces and conditions within a particular area.

C. Review other Sections in which primers are provided to ensure compatibility of the total system for various substrates. On request, furnish information on characteristics of finish materials to ensure use of compatible primers.

D. Notify General Contractor and Government about anticipated problems when using materials specified over substrates primed by Others.

3.2 PREPARATION

A. Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and similar items already installed that are not to be coated. If removal is impractical or impossible because of size or weight of the item, provide surface-applied protection before surface preparation and coating. After completing finishing operations in each space or area, reinstall items removed using workers skilled in the trades involved.

B. All surfaces to be finished shall be power-washed and/or scraped and wiped cleaned free of loose dirt and dust before finishing. After the first coat, putty holes, cracks, etc. with putty of a color to match that of finish. Bring putty flush to the adjoining surface.

C. Metal surfaces which are not galvanized or shop-coated shall be washed with mineral spirits to remove dirt and grease. Remove rust or scale by wire brushing or sandpapering clean.

D. Clean and treat galvanized metal chemically with a compound designed for this purpose, such as "Lithoform", "Stibley", or "Solfo Metallic Coat", in accordance with the paint manufacturer's instructions.

E. Sand hard, glossy and previously-painted finishes to insure adhesion. Spot prime with primer specified for new surfaces where existing paint or primer has been partially removed by blistering, peeling, rupture, or cracking. Completely remove existing finish if 25 percent or more of the existing finish has failed or can be easily scraped off the surface.

WICA - 304936 09 90 00-5

3.3 APPLICATION

A. Apply all materials under adequate illumination.

B. Do not coat over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to formation of a durable coating film.

C. Provide finish coats that are compatible with primers used.

D. The term “exposed surfaces” includes areas visible when permanent or built-in fixtures, grilles, convector covers, covers for finned-tube radiation, and similar components are in place. Extend coatings in these areas, as required, to maintain system integrity and provide desired protection.

E. Coat surfaces behind movable equipment and furniture the same as similar exposed surfaces. Before final installation of equipment, coat surfaces behind permanently fixed equipment or furniture with prime coat only.

F. Sand lightly between each succeeding enamel or varnish coat.

G. Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for coating as soon as practicable after preparation and before subsequent surface deterioration.

H. The number of coats and film thickness required are the same regardless of application method. Do not apply succeeding coats until previous coat has cured as recommended by manufacturer. If sanding is required to produce a smooth, even surface according to manufacturer’s instructions, sand between applications.

I. If undercoats, stains, or other conditions show through final finish coat, apply additional coats until final coat film is of uniform finish, color, and appearance. Give special attention to ensure that edges, corners, crevices, welds, and exposed fasteners receive a dry film thickness equivalent to that of flat surfaces.

J. Allow sufficient time between successive coats to permit proper drying. Do not recoat surfaces until previous coat has dried to where it feels firm, and does not deform or feel sticky under moderate thumb pressure, and until application of another finish coat does not cause undercoat to lift or lose adhesion.

K. Apply finish coatings by brush, roller, spray, or other applicators according to manufacturer’s instructions, and as follows:

1. Brushes: Use brushes best suited for type of material applied. Use brush of appropriate size for surface or item being coated.

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

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

L. Apply coating materials no thinner than manufacturer’s recommended spreading rate to achieve dry film thickness indicated. Provide total dry film thickness of the entire system as recommended by manufacturer.

M. Painting of mechanical and electrical work is limited to items exposed in occupied spaces. Mechanical items to be painted include, but are not limited to, the following:

1. Uninsulated metal and plastic piping

2. Pipe hangers and supports

3. Tanks that do not have factory-applied final finishes

4. Duct, equipment, and pipe insulation having “all-service jacket” or other paintable jacket material

5. Mechanical equipment that is indicated to have a factory-primed finish for field painting

WICA - 304936 09 90 00-6

N. Before applying finish coats, apply a prime coat, as recommended by manufacturer, to material that is required to be coated 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.

O. Pigmented (opaque) finishes: Completely cover surfaces as necessary to provide a smooth, opaque surface of uniform finish, color, appearance, and coverage. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections will not be acceptable.

P. Match approved samples for color, texture, and coverage. Remove, finish, or recoat work not complying with requirements.

3.4 FIELD QUALITY CONTROL

A. The Government reserves the right to invoke the following test procedure at any time and as often as the Government deems necessary during the period when paint is being applied:

1. The Government may engage a qualified independent testing agency to sample paint material being used. Samples of material delivered to Project will be taken, identified, sealed, and certified in the presence of Contractor.

2. The Government may direct Contractor to stop painting if test results show material being used does not comply with specified requirements. Contractor shall remove noncomplying paint from Project site, pay for testing, and repaint surfaces previously coated with the noncomplying paint. If necessary, Contractor may be required to remove noncomplying paint from previously painted surfaces if, on repainting with specified paint, the two coatings are incompatible.

3.5 CLEANING

A. At the end of each workday, remove empty trash cans, rags, rubbish, and other discarded paint materials from Project site.

B. After completing painting, clean glass and coating-spattered surfaces. Remove spattered paint by washing and scraping without scratching or damaging adjacent finished surfaces.
