PremiCote P79B is a water based environmentally friendly roofing primer developed to be used on BUR, mod bit, cap sheet and metal substrates. This product can be applied as a primer coat for a variety of roof coatings. PremiCote P79B has excellent resistance to heat, cold, moisture and weathering. This primer also sets up quickly to allow the base coat of the desired elastomeric to be applied soon after application. It is used as a blocking or barrier coat to eliminate bleed through to the top coating system.

PremiCote P79B may also be applied to a wide range of substrates which include, but are not limited to, wood, metal, concrete, masonry, various single ply membranes, spray polyurethane foam and most commonly used roof coatings. It is pigmented black to speed the curing process and increase roof surface temperature before application of spray polyurethane foam or roof coatings. The environmentally safe formulation makes PremiCote P79B the ideal solution for applications and projects that require such.
