Highly reflective roof coating reduces roof surface temperature and prolongs life of roof. Forms a longer lasting bright aluminum finish. Reduces interior temperatures in summer. Use on prepared roll roofing, asphalt built-up roofs, weathered, galvanized iron and tin. Apply to dry surface only. Apply with good quality soft bristle brush, long-napped roller, or commercial grade spray equipment. Apply liberally, brushing in 1 direction only. Do not overlap. Over-brushing will interfere with leafing action of aluminum. Coverage is 1 to 1.2 Gal. per 100 Sq. Ft. Application rate may vary according to the type, age, and condition of the surface. Aluminum paste meets ASTM D-2824 Type 3.
