Del-Val 305 SBS Modified Aluminum Roof Coating is a highly rubberized aluminum roof coating. Formulated using selected asphalts and blended with high quality aluminum pigments, refined solvents and SBS rubber. Del-Val 305 SBS Modified Aluminum Roof Coating provides outstanding expansion and contraction along with excellent reflectance. When the product is applied, it dries to a flexible rubber-like film that protects the roof’s surface from destructive UV rays and reduces roof temperatures.


Del-Val 305 is formulated for applications over metal roofs, new or existing built-up roofs, APP, SBS, smooth or granulated surfaces and mobile home roofs.


Prepare the roof surface by sweeping clean any dust, dirt or debris. Use a wire brush to remove rust from metal. Roof surface must be oil-free and free of moisture both on and beneath the surface. Repair all leaks and problem areas.


Apply with a soft bristled brush, paint roller or heavy-duty spray equipment. Product should be mechanically mixed for several minutes before applying. Spread the product uniformly over the roof surface. Do not apply over wet substrates or in inclement weather. Do not apply if ambient temperature will drop below 32° F in a 24-hour period or dew will settle before coating is allowed to dry.


Apply at the rate of 1.5 to 2 gallons per 100 sq. ft. Coverage may vary on different roof surfaces.

DO NOT THIN. DO NOT HEAT CONTAINER. DO NOT store in an area where temperatures exceed 120°F. DO NOT APPLY IF THERE IS A THREAT OF RAIN OR DEW WITHIN 24 HOURS. Applying Del-Val 305 directly over hot applied asphalt can result in alligatoring. Allow roof to cure thoroughly before coating.
