Create A New AccountJ-B Weld WaterWeld is a specially formulated epoxy putty that plugs leaks and patches holes and cracks in almost any material — even underwater. Ideal for plumbing, fuel tanks, tubs, showers, drains, pools, spas, boats, and potable water tanks, it sets in 15–25 minutes and cures rock-hard in one hour to an off-white finish.
Once fully cured, WaterWeld can be drilled, tapped, filed, sanded, and painted, making it a versatile permanent repair solution. It delivers a tensile strength of 900 PSI and withstands temperatures up to 300°F, giving you a reliable, long-lasting bond in demanding wet and high-heat environments. Pack of 6 × 2 oz units.
