CertainTeed FlintPrime Low VOC Asphalt Primer is formulated with low-VOC, penetrating solvents that promote the adhesion of roofing materials to the roof surface. FlintPrime Low VOC Asphalt Primer is available as either a quick-dry aerosol or a liquid grade. It is a superior prime coat for sealing masonry, roofing surfaces and metal. It is very thin bodied and is designed to seal and penetrate the surface, bonding contaminants that can contribute to adhesion failure, and provides an excellent base to which coatings can adhere. It is the ideal base coat before applying asphalt peel-and-stick membranes.
