JB Weld Waterweld 2oz Epoxy Putty, Underwater Repair for Boats, Plumbing, and Fuel Tanks
JB Weld Waterweld 2oz Epoxy Putty, Underwater Repair for Boats, Plumbing, and Fuel Tanks
JB Weld Waterweld 2oz is a kneadable epoxy putty made to plug or seal leaks, holes, and cracks in almost anything, including plumbing, fuel tanks, tubs and showers, drains, pools and spas, boats, and potable water tanks. Its standout feature is that it can be applied and will set up even underwater, making it a practical fix for below-the-waterline hull repairs, thru-hull leaks, and other wet or submerged surfaces where a standard adhesive cannot be used. To apply, the putty is thoroughly kneaded with the fingers until it reaches a uniform off-white color, then pressed firmly onto the surface that needs repair. Waterweld begins to set in 25 minutes and cures hard within one hour. Once fully cured, the repair can be drilled, tapped, filed, sanded, and painted, allowing it to be finished and blended into the surrounding surface. The cured epoxy reaches a strength of 4370 PSI and will withstand water pressure up to 500 PSI and temperatures up to 250 degrees F, giving it the durability needed for ongoing exposure to water and heat. It bonds well to aluminum and fiberglass and is also suited to automotive use. This makes JB Weld Waterweld a versatile, go-to repair compound for boat owners and anyone dealing with a leak that needs a fast, waterproof fix.
