05206 Marine Adhesive Sealant, White, 1 Oz Tube

3M 5200 is a one-component, high-strength, moisture-curing polyurethane sealant designed for permanent bonding and sealing in marine environments. This gap-filling adhesive creates a firm, rubbery, waterproof seal on joints and boat hardware both above and below the waterline. It bonds wood, gelcoat, and fiberglass with exceptional strength and flexibility, making it ideal for hull seams, porthole installation, through-hull fittings, deck work, and other marine repairs.

The sealant accommodates structural movement and stress caused by vibration, swelling, shrinking, or shock, ensuring your marine projects withstand the demanding conditions of saltwater and weathering. Its flexibility prevents cracking and failure when boats experience the constant motion and temperature changes of the marine environment. Whether you're a professional boatbuilder or a DIY enthusiast maintaining your vessel, 3M 5200 delivers the reliability that has made it a trusted choice in the marine industry for over 50 years.
