Marineweld Epoxy Adhesive, 1-oz., 2-pack

J-B Weld MarineWeld is a specially formulated two-part epoxy cold weld system designed for strong, lasting repairs on boats, marine equipment, and water-exposed surfaces. This adhesive bonds aluminum, metal, composites, fiberglass, and other dissimilar materials, making it ideal for hull repairs, saltwater equipment fixes, and any application where waterproof durability is essential. Whether you're fixing a surfboard, repairing a boat hull, or maintaining marine equipment, MarineWeld provides permanent bonding that withstands extreme conditions.

MarineWeld cures as hard as steel and remains impervious to saltwater, chemicals, oil, and other corrosive materials. Once fully cured, the bond retains full strength above or below the water surface, making it perfect for both recreational and commercial vessel maintenance. The dual 1-ounce tubes give you enough material for immediate repairs plus a spare for future fixes.
