This high-performance polyurethane adhesive/sealant becomes tack free in 48 hours, completely cures in 5 to 7 days with no shrinkage. The seal is extremely strong, retains its strength above or below the water line. Stays flexible too - allows for structural movement. Stress caused by shock, vibration, swelling, or shrinking is effectively absorbed. Has excellent resistance to weathering and salt water. Easy-to-apply with manual caulking gun. Remains workable with trowel or spatula up to 4 hours after application. Will not sag or flow in vertical or horizontal seams.A permanent solution for bonding marine substrates like wood, fiberglass, and metalPolyurethane chemically reacts with moisture to deliver strong, flexible bondsTough yet flexible polyurethane polymer is ideal for deck housings, hull fittings, porthole mounting, fiberglass transoms, and underside moldingResists saltwater and weathering both above and below the water lineElastomeric bonds seal against the elements, maintain joint movementNonshrinking - bonds dissimilar materials
