MasterWeld 941 is a one-component polyurethane based trowel-grade, waterproof adhesive. Its elastomeric properties enable it to move with wood and other materials as they expand and contract. MasterWeld 941 contains no solvents or water, so it will not cause wood to expand. MasterWeld 941 proves excellent initial green strength and outstanding bond strength. It is formulated for indoor and outdoor applications.
