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.


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