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.

Real Results

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.
