Caulking & Adhesives

Professional Adhesives and Caulking for Lasting Boat Protection

Maintaining the structural integrity and watertight seals of your boat is non-negotiable. At Fawcett Boat Supplies, we stock only the highest quality sealants, bonds, and fillers specifically formulated to withstand the harsh marine environment. From flexible seam sealing to permanent structural bonding, we are your trusted source for professional-grade products that deliver lasting protection.

Finding the Right Marine Sealant

The choice of sealant is critical to preventing water intrusion and damage. Our selection of marine caulk and marine caulking is engineered for superior adhesion and flexibility, ensuring a watertight barrier that resists UV damage, temperature fluctuations, and movement. We feature products to help you find the best caulk for marine use on deck joints, portlights, and thru-hulls. Always look for the marine grade caulk designation.

Our inventory includes trusted brands and specific products such as:

• BoatLIFE Life Calk®: A long-lasting polysulfide compound, ideal for teak decks and below-the-waterline seams.
• Sikaflex® 291 LOT: A popular polyurethane marine caulk and adhesive used for general sealing and bedding.
• 3M™ Marine Grade Silicone Sealant: Excellent white adhesive caulk for above-the-waterline applications, providing a mildew-resistant, non-yellowing seal.

Structural Bonding and Adhesive Solutions

Beyond sealing, many boat projects require a permanent bond. We offer advanced formulas that function as both a sealant and a powerful adhesive. Products often referred to as adhesive caulk or caulk adhesive provide an excellent dual-purpose solution for non-structural tasks.

When seeking a powerful, reliable bond, customers often ask what is the best marine adhesive. Our inventory includes industry-leading polyurethane and epoxy compounds. You can find the best adhesive caulk for jobs ranging from simple trim attachment to heavy-duty structural bonding. Top sellers include:

• 3M™ Marine Adhesive Sealant 5200: The industry standard for a permanent, high-strength bond on through-hull fittings where leakage is not an option.
• 3M™ Marine Adhesive Sealant 4200 Fast Cure: A strong adhesive sealant offering less permanence than 5200, making it ideal for deck hardware that may need removal later.

Adhesives, Removal, and Best Practices

While many boaters ask caulk can be used as an adhesive, a dedicated structural adhesive is necessary for critical components. For repairs, knowing how to remove marine caulk effectively is key to a successful new application. We stock specialized solvents and tools to safely strip old sealants.
