Boat Life

<h3>About BoatLIFE</h3><p><strong>BoatLIFE</strong> has been one of the most trusted names in marine maintenance for over 65 years. Founded in 1959 by Edwin Kehrt — a veteran of the U.S. Army Corps of Engineers whose wartime experience introduced polysulfide compounds to the marine world — the brand has grown from a single pioneering product into a comprehensive line of boat care solutions. Manufactured in North Charleston, South Carolina, every BoatLIFE product is proudly made in the USA, and the company's in-house research and manufacturing model ensures consistent quality control across its entire catalog.</p><p>Life Industries Corporation, the parent company behind BoatLIFE, is a privately held, second-generation business that has continuously expanded its formulations to keep pace with the evolving needs of pleasure craft, commercial vessels, and even cruise ship operators. In 1984, the brand extended its reach to major cruise lines, supplying its signature Life-Calk sealant for large-scale deck maintenance — a testament to just how much professional-grade confidence the brand commands.</p><h3>What BoatLIFE Makes</h3><p>At the heart of the BoatLIFE product family are its industry-leading <a href="/7264-boat-life-caulks-sealants-200248">Caulks &amp; Sealants</a>. The flagship Life-Calk&trade; is a permanently flexible marine polysulfide sealant that can be sanded, painted, and applied both above and below the waterline — making it the go-to solution for waterproofing seams, bedding deck hardware, and sealing joints in virtually any marine application. Alongside Life-Calk, the brand offers silicone rubber sealants, teak deck sealants, and polyurethane adhesive/sealers to cover every bonding and sealing scenario a boater might encounter.</p><p>Proper sealant work starts with proper surface preparation, which is why BoatLIFE's <a href="/7264-boat-life-adhesive-cleaner-remover-200068">Adhesive Cleaner &amp; Remover</a> products are such an important part of the lineup. These solvents are formulated to strip away old caulk, residue, and contaminants so that new sealants bond correctly and last as long as they should.</p><p>For boaters with teak decks, BoatLIFE offers a dedicated range of <a href="/7264-boat-life-teak-products-201056">Teak Products</a>, including the well-known Teak Brite&trade; system. Teak is one of the most maintenance-intensive materials found on a vessel, and BoatLIFE's purpose-built cleaners, brighteners, and teak sealants help restore weathered wood and protect it against UV damage, teak oils, and the elements.</p><p>When surface damage goes beyond what a sealant can address, the brand's Fillers step in to restore structural integrity and cosmetic appearance to fiberglass and other hull materials. And to make every application as clean and precise as possible, BoatLIFE also offers a selection of <a href="/200247-caulking-guns-tools-boat-life-7264">Caulking Guns &amp; Tools</a> matched to the cartridge sizes used across its sealant line.</p><h3>Why Boaters Trust BoatLIFE</h3><p>What sets BoatLIFE apart isn't just the longevity of the brand — it's the philosophy behind it. By manufacturing its own product lines entirely in-house, the company maintains direct control over every stage of production. Formulations are continuously researched and refined, and many of the brand's proprietary solutions hold patents developed by its own engineering team. Whether you're a weekend recreational boater or maintaining a commercial fleet, BoatLIFE offers the depth and reliability of a brand that has spent more than six decades solving real problems on the water.</p>
