Teakdecking Systems (TDS) SIS 440 Teak Deck Caulk Cartridge 10.3oz - Gray

• HIGH QUALITY MARINE POLYMER – 10.3oz Cartridge of boat sealant waterproof caulking made with a one-part silane polymer that forms a solid, rubber-like compound. 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. Stays flexible over time and requires no primer, making it an efficient marine sealant choice. Solvent-free and low waste, it's an environmentally conscious solution for marine use.
• 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 68°F (based on ¼" x ¼" seams). Larger seams may require more time. A dependable marine grade sealant for demanding environments.
• INDUSTRY-STANDARD FORMULA & PACKAGING OPTIONS – Available in black, white, and gray, with a 15-month shelf life from the date of manufacture (printed on cartridge). Meets ASTM C920 standards and manufactured in an ISO 9001-certified facility, making it a consistent and compliant option for ongoing marine caulking and decking work.
