P-305 Asphalt Bleed-Block Primer
$110.00 - $5,500.00
305 Asphalt Bleed-Block Primer is a water-based acrylic primer designed to control asphalt bleed-through and smooth granulated surfaces prior to silicone coating application. It fills surface voids on granulated modified bitumen, helping silicone coatings build to required mil thickness more efficiently. P-305 is a cost-effective priming option and is specified for warranty silicone systems over asphalt-based substrates.
- Asphalt Bleed Control: Blocks asphaltic compounds to reduce staining and discoloration of silicone coatings.
- Surface Smoothing for Improved Yield: Fills granulated valleys to improve silicone coverage efficiency and help achieve required mil builds.
- Warranty-Driven System Component: Specified for warranty silicone applications over asphalt-based substrates. Typical coverage: ~1.5 gal/sq on granulated surfaces and ~1.0 gal/sq on smooth surfaces to support required silicone mil build.
