SENTINEL® H2O Bonding Adhesive is a water-based polymeric adhesive specially designed for adhering SENTINEL PVC membranes and flashings to a variety of substrates for horizontal or vertical applications. SENTINEL H2O is expressly formulated to provide superior bonding strength while containing zero VOC’s.
SENTINEL H2O Bonding Adhesive is designed for use with SENTINEL membranes and flashings over approved substrates. Prior to application, stir by hand to ensure a homogenous mixture. Ensure that the substrate is clean, dry and free of any debris, grease or oil. Apply the adhesive to the substrate using a 3/8” nap roller, mate SENTINEL membrane while substrate is still wet and broom into place. Coverage rates vary for fleece backed and non-fleece backed applications. SENTINEL H2O Bonding Adhesive should only be applied when temperature is 50°F (10°C) and rising.
