Products / GacoRoof GR16 Series

GacoRoof GR16 Series is a single-component, 100% silicone, elastomeric, air-dry roof coating that forms a seamless membrane to seal and repair existing roofs and protect against leaks, permanent ponding water, and severe weather. It adheres to most substrates, including built-up roofs, cap sheet, metal, modified bitumen, and sprayed polyurethane foam (SPUF), without a primer in most cases, and remains permanently flexible under ponding water or snow load. The product data sheet states it meets ASTM D6694 and carries a UL 790 (ASTM E108) Class A external fire exposure rating.
