Products / GacoFlex A4271 BleedTrap Base Coat

GacoFlex A4271 BleedTrap Base Coat is a single-component, water-based acrylic sealer for roofing substrates containing bitumen, including built-up roofing, all types of modified bitumen, and smooth or granulated asphaltic membranes. It encapsulates oil exuding from bituminous substrates to help inhibit bleed-through into GacoFlex topcoats, and is not intended for gravel-surfaced built-up roofs. It is red, and the data sheet reports physical properties tested against ASTM D6694 requirements.
