Vanguard Bleedblocking Primer

Vanguard Acrylic Bleed Blocking Primer is a bleed blocking primer for our Falcon silicone roof systems. Design to be applied to asphalt, mod-bit, and built-up roofs, it blocks discoloration from the asphalt bleeding through to the silicone coating. It also increased the yield of the silicone by filling in the valleys between the granules of asphaltic roofs.
