Product Information Sheet
A100 AtcoCoat
Asphalt Coating & Adhesive

USES: A100 AtcoCoat protects surfaces exposed to the weather. AtcoCoat is a superior asphalt protective coating for roofs, foundations, gutters, concrete, metal, and wood. Also, use AtcoCoat to cement in place rigid insulation boards, to adhere Fields reinforcing sheets, to install Fields reflective cap sheets, and to apply Fields reflective minerals. AtcoCoat is compatible with SEBS, APP, and SBS roofing products, and will adhere to most surfaces including roofing, skylights, foundations, wood, metal, glass, and concrete.

DIRECTIONS: A100 AtcoCoat is friendly to apply, especially in warm temperatures. Apply with a medium stiff bristle brush, a squeegee, or asphalt cutback spray equipment. Warm AtcoCoat to room temperature for easiest application. Clean gravel, dirt, vegetation, and debris from the application area. Make sure the application surface is smooth, firm, frost-free, and dry. Apply AtcoCoat directly from the container without diluting. Generously apply a protective coating with AtcoCoat at the uniform rate of 5 gallons per 100 square feet. First repair fissures, seal leaking penetrations, fix broken flashings, and reinforce degraded areas. Make a 3 layer repair with AtcoCoat and PolyWeb over fissures or to reinforce degraded areas. Refer to the PolyWeb label for installation directions. Install a Fields new roof, reroof, recover roof, reinforced coating, or waterproof membrane with AtcoCoat. Uniformly apply 5 gallons per 100 square feet of AtcoCoat as an adhesive under and between each layer of sheets, and as the protective surface coating. Refer to the label on the Fields reinforcing sheet selected for installation directions. For maximum protection and reduced energy costs, apply M800 RubrStar over the AtcoCoat. Allow the AtcoCoat a minimum of 90 days to set up before applying the RubrStar.

DESCRIPTION: A100 AtcoCoat is a quality asphalt coating and adhesive manufactured from 100% oxidized reroofing asphalt. Select raw materials have been formulated to make AtcoCoat a premium product. AtcoCoat provides superior elastic performance against thermal shock, the daily expansion and contraction of a roof caused by temperature changes. In addition, the sun's UV rays attack the roof membrane making it brittle and weak, inducing membrane ruptures during thermal shock cycles. AtcoCoat is your best defense against these attacks. With AtcoCoat your roofing and waterproofing installations will perform much longer. AtcoCoat has a UL Class A fire rating and is asbestos free.

SPECIFICATIONS: A100 AtcoCoat exceeds the standards of the American Society for Testing and Materials ASTM D 4479 Type 2. Maximum VOC is 350 grams per liter.
