J-B Weld 8277 2oz WaterWeld Water & Oil Resistant Epoxy Putty

J-B Weld 8277 2oz WaterWeld Water & Oil Resistant Epoxy Putty – World’s Strongest Bond

J-B Weld WaterWeld (8277) is a hand-mix, moldable epoxy putty engineered for permanent repairs in wet or submerged conditions. Tear off what you need, knead to a uniform color, and press it into place—no measuring tools required. WaterWeld sets in 25 minutes and cures in 1 hour to an off-white finish rated at 4,370 PSI. Once cured, it can be drilled, tapped, filed, sanded, and painted, making it useful for shaping patches and rebuilding worn edges. The putty adheres to fiberglass, PVC/plastic, copper, brass, iron, aluminum, wood, and more, and it holds above or below the waterline. It’s labeled NSF/ANSI 61 Drinking Water Safe, and resists water, oil, gas, diesel, hydraulic fluids, and most chemicals, with service temperatures to 250°F. From tubs, showers, and pools to marine fittings, fuel tanks, and automotive parts, WaterWeld delivers dependable, waterproof repairs right from the stick.

The hand-mix epoxy putty presses into cracks, seams, and pinholes on PVC, fiberglass, and metal without dripping. A 25-minute set limits clamp time, and the 1-hour cure supports same-shift turnaround. On boats and pools, crews can patch components under water; in plumbing, the NSF drinking-water safe label covers potable systems. With strong adhesion and resistance to fuels and oils, it also handles fuel tank repair and light automotive work—all from a compact 2 oz stick.

Why Customers Select the J-B Weld 2oz WaterWeld Water & Oil Resistant Epoxy Putty

Crews choose this underwater epoxy because it bonds where other adhesives fail—on wet, dripping, or submerged surfaces. For pipe repair, pool repair, and marine patches, the putty format presses into cracks and pinholes and sets in about 25 minutes. After a 1-hour cure, it can be drilled and sanded so hardware fits cleanly. The off-white cure looks right in bath and galley spaces, and the NSF potable-water listing covers work on drinking-water lines. With 4,370 PSI strength and resistance to fuel and oil, WaterWeld also handles emergency fuel-tank and automotive fixes, providing a reliable, waterproof solution from tool bag to jobsite.
