Airless sprayers use a hydraulic pump to atomize the coating. Can you spray roof coating with a paint sprayer?Īn airless sprayer is the most efficient way to apply roof coatings. These types of materials are typically used in combination of base coat and topcoat. There are two types of polyurethane roof coatings: aromatic and aliphatic. Polyurethane coatings provide the best rates of all coatings for impact resistance and for foot traffic. They do increase reflectivity and UV protection to the roof substrate but do not improve appreciable mil thickness to the roof. Unlike acrylic coatings, aluminum coatings do not provide any waterproofing properties. This is important because the higher the level of viscosity, the less likely the coating is to run. The extra fibers in fibered coatings reinforce their strength and also control the viscosity (thickness) of the liquid. What’s the difference between fiber and non fibered roof coating?Īs you might guess, fibered coatings contain extra fibers, whereas non-fibered coatings do not. It may be applied to smooth surface BUR, SBS modified bitumen membranes, metal roof surfaces and roll roofing as a protective coating.ĪPPLICATION: Rust-Oleum 15 Year Fibered Aluminum Roof Coating can be applied by brush, roller, or spray gun to specified coverage rates. 71 Fibered Asphalt Roof Coating is designed to provide excellent weathering protection on most roof surfaces.
