Metal Roof Paint Instructions

"WB" may be brushed, rolled or sprayed. Use smooth, light, even strokes ending with all going in the same direction. Apply thickly at 200 sq. ft. to a gallon coverage. Seals pin holes and other minor defects.

Apply waterborne SHOWER-PROOF "WB" over asphalt coatings, vinyl, copper, or any zinc coated (galvanized) metal, including Follansbee™ Terne IITM.

Clean up:
"WB": use soap and water

Cautions:
Paint only when weather conditions are warm and dry. Apply only at temperatures from 40°F to 80°F (air and surface). Do not paint if rain is forecast within the tack-free time. Starting after 10 am and stopping by 4 pm gives best results. Condensation on wet paint film will not affect adhesion or durability. Never paint over condensation. Painting at temperatures above 80°F could cause coatings to dry too quickly, resulting in poor adhesion and flexibility. Re-coating too quickly can delay thorough drying and cause bubbling and wrinkling. Refer to the Material Safety Data Sheet for complete health and environmental information.

It is suggested that painters wear rubber-soled shoes while working to minimize wear on the metal roof paint. Avoid unnecessary walking on the metal roof. Do not use the metal roof for storage.

Do not apply when ambient or surface temperatures are below 40°F or above 80°F.

Do not apply when there is a threat of rain.

Not recommended for use on EPDM roofing. Not recommended for use on fluoropolymer (i.e. KYNAR) finishes.

Protect "WB" From Freezing

Surface preparation of new Terne II:
Surface to be coated must be clean and free of water, oil, rust, dirt, mildew, soldering fluxes, tree sap, or any foreign matter that can potentially interfere with adhesion. If cleaning is necessary, we recommend a detergent wash and rinse as described below. Apply two coats of SHOWER-PROOF "WB" by brush, roller or spray.

Surface preparation for previously coated Terne:
If the surface is not clean, power wash with TSP to remove "chalk", dirt, rust and loose paint. Rinse thoroughly and let dry completely. Alternately, hand scrape peeling sections either wood or plastic scraper (the sharp end of a cedar shake works well) then clean rust areas with a stiff bristle brush - a wire brush or metal scraper could damage the tin. Then pour a heavy-duty solution of TSP in warm water on roof and scrub with stiff bristled brush or floor broom. Rinse thoroughly and let dry completely. If rust is present after cleaning, spot prime rusted areas with Calbar red oxide primer 10-520.

Tinting/Thinning:
Not recommended, but "WB" only may be thinned up to 2% (3 ounces/gal.) to improve workability in hot, windy conditions.

Stirring:
Stir the paint thoroughly, immediately before using and frequently during application.
