Learn More About Coating Over  Aged  Single-Plies

 

AcryShield® A502 is a one component, low VOC, water-borne base coating designed for application to aged single-ply roofing membranes. A502 is the industry standard, high performance base coat for hard to coat surfaces such as aged Hypalon, PVC, aged TPO, and EPDM roofing. A502 eliminates the need for costly replacement and pre-treating EPDM with a caustic solution before the coating is applied.
