Acrylic roof coating: An acrylic roof coating also protects against the wind and sun and is resistant to moss and algae growth, similar silicone roof coatings. Manufacturers create these coatings from acrylic resin. They can be applied on various roof membrane surfaces, such as metal systems and single-ply membranes. Typically, one or more coats are applied. Keep in mind that it’s best not to apply acrylic coatings in extremely cold temperatures, as they cure well in warm weather with low humidity.
