National Coatings has the unique ability to address the difficulties and failures that aged single-ply roofing experiences. Most roof coatings require caustic primers, acid etching agents, or high VOC solvents that need to be rinsed off and sometimes collected for disposal, adding additional cost to a roof life extension project. NCC's products have the unique ability to coat to single-ply roofing membranes without the need to use any of these harmful products. Our state of the art single-ply coating systems adhere directly to single-ply substrates providing a monolithic membrane without any of the seams that can be prone to failure. Coating restorations do no count as a new roof under most building codes, eliminating the need for periodic and costly tear-off's. This process allows for a truly sustainable roofing system by performing coating maintenance every 10 years.

AcryPly_Acrylic_Diagram_-_A502_eliminatedWhat's our secret? The AcryShield® A502 base coat! This single-ply base coat is the industry leader, ultra low VOC, high performance base coat for hard to coat surfaces such as Hypalon®, TPO, EPDM, and PVC roofing. A502 base coat eliminates the need for costly roof replacement and provides unique AcryLock technology to tenaciously adhere directly to EPDM, TPO and Hypalon without the need for additional primers or an etching rinse. A502 also provides an additional layer of waterproofing, superior adhesion, and resistance to ponded water.
