Offers excellent UV and chemical resistance, superior temperature stability, and is easy to sand. This marine grade sealant improves project turnover time and is trusted in long-term marine caulking applications.
• FLEXIBLE & PRIMER-FREE Thixotropic paste that does not drip or sag, allowing for controlled application on vertical and horizontal seams.

• FIRST-CLASS APPEARANCE Our marine caulking sealant is designed for seams 3 to 10.3mm wide to achieve a clean, uniform finish on teak decks. Seam depth should be equal to or greater than seam width for proper adhesion. When used with bond-breaker tape, this marine caulk helps support long-lasting, visually consistent deck seams.
• OPTIMIZED CURE TIME FOR CONSISTENT RESULTS Cures to a firm, flexible bond with reliable adhesion and durability, offering advantages over traditional polysulfide, polyurethane, and MS polymers. Gray caulk is sandable after a minimum of 15 days at 68F (based on " x " seams). Larger seams may require more time. A dependable marine grade sealant for demanding environments.
