National Coatings’ AcryShield A500 roof coating is the industry-standard acrylic, elastomeric coating for sprayed polyurethane foam (SPF) roofing systems. AcryShield A500 has optimum adhesion to SPF. It can also be applied over single-ply and metal roofing in colder climates where additional low temperature flexibility is required. A500 exceeds ASTM D6083 requirements. The product may be used as a topcoat on BUR, mod bit, EPDM, SPF, asphalt, Hypalon, TPO, and metal roofs.
