SP-1500 is a high-quality, single-component acrylic primer intended for spray brush or roller application. The plasticizer-free formula is water-based and designed to provide excellent adhesion as well as resistance to plasticizer migration. The primer features the ability to maintain a watertight barrier while still permitting the passage of trapped moisture. It also demonstrates exceptional adhesion to the majority of single-ply surfaces, which include Hypalon, aged TPO and PVC.
