3m 10 Oz. White Marine Adhesive Sealant 5200

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.
