3.02 PREPARATION

A. Remove electrical plates, hardware, light fixture trim, and fittings prior to preparing surfaces or applying any finish. Re-install the above after the Painting Work has been completed.

B. Correct minor defects and clean the surfaces that affect the Work of this Section in accordance with

the Paint Manufacturers written instructions. Schedule the cleaning and painting so that contaminants from the cleaning process will not fall onto wet, newly painted surfaces. Do not paint over dirt, scale, rust, grease, or conditions otherwise detrimental to the formation of a durable paint film.

C. Touch-up any shop-primed or galvanized steel surfaces which have been damaged. Sand and

scrape to remove loose primer and rust. Feather edges to make touch-up patches inconspicuous. Clean surfaces as directed by Manufacturer.

DIVISION 9 PAINTING

SECTION 09900



3.03 PROTECTION

A. Protect: the work of other trades, whether it is scheduled to be painted or not, against any damage by the Work specified herein. Repair all damage as directed by Architect, at no cost to the Agency.

B. Furnish drop cloths, shields, and protective methods to prevent spray or droppings from disfiguring

other Work. C. Remove empty paint containers from the Site, and dispose of legally.

3.04 APPLICATION

A. General: Apply products in accordance with the Manufacturer’s written instructions. Do not apply

finishes to surfaces that are not dry. Apply each coat to a uniform finish. Sand lightly and vacumn and/or wipe with tack cloths between coats. Allow applied coat to dry for the time period recommended by the Manufacturer before applying the next coat.

C. Minimum Coating Thickness: Apply each paint system at not less than the Manufacturer's

recommended wet/dry film thickness, or spreading rate. D. Additional Prime Coats: Re-coat primed and sealed surfaces where there is evidence of suction

spots or unsealed areas, as required to assure a finish coat with no burn through, or other defects.

E. Additional Finish Coats: When undercoats, stains or other conditions show through the final coat of paint, apply additional finish coats of paint until the paint film is of uniform finish, color and appearance, and is acceptable to the Architect.

F. Application: Apply each coat of paint free of cloudiness, spotting, holidays, laps and brush marks,

runs, sags, ropiness, or other surface imperfections. Apply by brush, spray, or roller as deemed needed for best finish.

3.05 MAINTENANCE

A. As the Work proceeds, promptly remove paint where spilled, splashed, or spattered. B. During the progress of the Work, maintain the premises free of unnecessary accumulation of tools,

surplus materials and debris.

C. Collect cotton waste, cloths, and other materials that constitute a fire hazard, place in closed metal containers, and remove daily from the Site.

3.06 CLEANUP AND PROTECTION

A. Clean Up: Remove from the Site on a daily basis all discarded paint materials, rubbish, cans and rags. Upon the completion of the Painting Work, clean all window glass and other paint spattered surfaces. Remove spattered paint as directed by the Manufacturer of the product, using care not to scratch or otherwise damage any finished surfaces.

B. Provide "Wet Paint" signs: as required to adequately inform the public of newly painted surfaces.

DIVISION 9 PAINTING

SECTION 09900



C. Protect: newly painted surfaces from any kind of damage until the Date of Substantial Completion. If any painted surface should be damaged in any way, repair damaged areas by cleaning, sanding, priming and finish painting the surface as required by the Architect.
