Bleed Blocker (PrBB) is a single component 100% acrylic, water-based, plasticizer-free primer in fluid-applied roofing systems formulated to block discoloration and bleed-through associated with asphaltic roofing substrates.
PrBB has excellent adhesion to most surfaces, including metal, concrete, smooth, BUR asphalt and modified bitumen, granular cap sheets, properly prepped single-ply membranes, and other approved surfaces.
General Purpose Primer (PrGP) is a single-component 100% acrylic, water-based, plasticizer-free black primer.
PrGP warms quickly in direct sunlight. It’s a “breathable” primer, allowing water vapor to transit the dry film and leave the substrate. The result is a warmer, drier substrate that offers better SPF adhesion and yield.
PrGP has excellent adhesion to most surfaces, including aged asphalt, concrete, primed metal, wood, smooth BUR, aged spray foam, and other approved surfaces.
