298 Asphalt Emulsion may be used as a surface protectant or as a waterproofing compound using polyester and or fiberglass reinforcements. Applied as a roof protectant, 298 Asphalt Emulsion's unique formulation allows the film to 'breathe' while drying and is waterproof upon curing. Roof surfaces protected or surface primed with 298 Asphalt Emulsion are especially suited for application of Western Colloid 525 SilverWhite Aluminum Reflective Coating.
