J-B Weld WaterWeld™ Epoxy Putty 57g – Waterproof Leak & Pipe Repair

J-B Weld WaterWeld™ Epoxy Putty 57g is a hand-mixable waterproof epoxy putty designed to plug and seal leaks and patch holes and cracks in a wide variety of materials. Specially formulated for wet environments, WaterWeld™ can set even underwater, making it an excellent choice for plumbing, marine, pool, spa and water-related repairs.

Ideal for repairing plumbing, pipes, fuel tanks, baths, showers, drains, pools, spas, boats and portable water tanks, WaterWeld™ provides a versatile solution when a strong, water-resistant repair is required.

The putty works on a range of materials, including fibreglass, PVC plastic, copper, brass, iron and aluminium. Its mouldable consistency allows it to be pressed into cracks, holes and damaged areas before setting, making it particularly useful where conventional liquid adhesives may be difficult to apply.

J-B Weld WaterWeld™ has a 1,300 PSI bonding strength and can withstand temperatures up to 148°C (300°F). Once cured, it is resistant to water, oil, gas, diesel, hydraulic fluids and most other chemicals, making it suitable for a broad range of demanding repair applications.

WaterWeld™ sets in approximately 25 minutes and fully cures in approximately 1 hour. Once cured, the hard repair can be drilled, tapped, filed, sanded and painted, allowing it to be finished to suit the surrounding surface.

For anyone looking for a waterproof epoxy putty, underwater repair compound, plumbing leak sealer, PVC pipe repair putty or epoxy for patching tanks, J-B Weld WaterWeld™ provides a strong and versatile repair solution.
