Great Stuff Polyurethane Subfloor Construction Adhesive is a heavy-duty, single-component adhesive designed for superior bonding of subfloors, drywall, foam panels, and various construction materials. Its moisture-cured formula ensures strong adhesion on dry, damp, or frozen lumber, providing fast grab and long-lasting strength.

Ideal for anchoring insulated concrete forms and sealing gaps during concrete pouring, it prevents leakage and enhances structural stability. The 16 oz. can features a smart dispenser for precise application and can be reused up to 30 days without dripping, making it a reliable choice for professional construction projects. Applies in 1/2 in. beads and 1 can replaces up to 8-quart tubes of traditional 28 oz. caulk adhesive at 1/4 in. beads.
