Seachoice Elastomeric Marine Sealants for All-Weather Protection
When it comes to protecting your vessel from water intrusion and the harsh marine environment, Seachoice delivers practical, affordable solutions through their line of elastomeric caulks and sealants. Designed specifically for boating applications, these marine-grade sealants provide the permanently flexible, tenacious adhesion needed to withstand constant exposure to moisture, temperature fluctuations, and UV radiation.
Fast-Curing Formulation for Above and Below Waterline Use
Seachoice elastomeric sealants cure in 1 to 7 days at temperatures ranging from 40°F to 130°F, making them versatile enough for year-round marine maintenance projects. Unlike traditional silicone sealants, these formulations can be used in place of silicone for both above and below waterline applications, including through-hole fittings. This dual-purpose capability makes them ideal for bedding deck hardware, sealing portlights, waterproofing hatches, and securing hull penetrations.
The sealant adheres tenaciously to fiberglass, wood, metal, glass, plexiglass, Lexan, and other plastics, providing the substrate compatibility that boat owners need when working with the diverse materials found on modern vessels. Whether you're maintaining a classic wooden runabout or a contemporary fiberglass cruiser, Seachoice sealants bond effectively to the surfaces that matter most.
Non-Staining and Sandable for Professional Results
One of the standout features of Seachoice's elastomeric formula is its non-staining, non-sagging characteristics. This means you won't see unsightly discoloration bleeding onto white gelcoat or teak trim—a common problem with lower-quality marine sealants. The cured sealant is both sandable and paintable, allowing you to achieve a clean, finished appearance that integrates seamlessly with your boat's aesthetic. Cleanup is straightforward using mineral spirits, making application and finishing more manageable for DIY boaters and professional marine technicians alike.
Affordable Marine Protection from a Trusted Brand
Seachoice was established in 1988 as a supplier of high-quality marine hardware and OEM replacement parts, and has since grown to offer thousands of marine products across multiple categories. The company is committed to delivering premium quality products at a competitive price, and offers a no-hassle warranty on everything they produce. This value-focused approach makes their elastomeric sealants an excellent choice for boaters who need reliable performance without the premium pricing of specialty marine brands.
Available in both clear and white formulations and multiple packaging sizes, Seachoice caulks and sealants provide the flexibility, durability, and ease of use that modern boat maintenance demands—whether you're preparing for a season on the water or making emergency repairs at the dock.
