Crafco Asphalt Primer is a specially formulated solvent-based asphalt primer that is used to improve adhesion of asphalt products to various surfaces, including asphalt concrete, Portland cement concrete, wood and metal. The primer is applied to the surface at the correct application rate, and then allowed to cure, prior to installation of the asphaltic product which will adhere to the surface. Typical uses include improving adhesion of asphaltic plug joints, self adhesive membranes and hot applied patching materials. The primer penetrates the surface, binds loose dust or other particulates, and cures to a hard, well bonded surface. VOC = 431 g/l.
