Expert Verdict Reviewed by the SuperArbor Pro Desk

On porous concrete, gypsum and masonry decks a penetrating asphalt primer is the difference between a membrane that bonds and one that delaminates. Apply PRO #3 in an even coat with no puddles and let it dry fully before torching, mopping or coating. On weathered BUR, priming before a black or reflective coating restores a uniform bonding surface.

Asphalt primers contain solvents; apply with adequate ventilation, keep away from ignition sources and follow the product safety data sheet.

Order TopShield PRO #3 Asphalt Primer in the 5-gallon pail to prepare your deck for built-up roofing.
