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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e JB Weld\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e JBWE8277\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Waterweld Epoxy Putty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrength:\u003c\/strong\u003e 4370 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Pressure Resistance:\u003c\/strong\u003e up to 500 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Resistance:\u003c\/strong\u003e up to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart Time (Set Time):\u003c\/strong\u003e 25 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCure Time:\u003c\/strong\u003e 1 hour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor, Cured:\u003c\/strong\u003e Off White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials:\u003c\/strong\u003e Aluminum, Fiberglass, Automotive surfaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnderwater Application:\u003c\/strong\u003e Yes, can be applied and set underwater\/wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinishing:\u003c\/strong\u003e Can be drilled, tapped, filed, sanded, and painted once cured\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eCan JB Weld Waterweld be applied underwater?\u003c\/strong\u003e Yes, JB Weld Waterweld epoxy putty can be applied and will set up even underwater, which is why it works for below-the-waterline hull repairs and other submerged leaks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long does Waterweld take to set and cure?\u003c\/strong\u003e Waterweld begins to set in 25 minutes and cures hard within 1 hour, after which it can be drilled, tapped, filed, sanded, and painted.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the strength of JB Weld Waterweld once cured?\u003c\/strong\u003e Once fully cured, JB Weld Waterweld (part JBWE8277) reaches a strength of 4370 PSI.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat water pressure and temperature can Waterweld handle?\u003c\/strong\u003e JB Weld Waterweld will withstand water pressure up to 500 PSI and temperatures up to 250 degrees F once cured.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat surfaces and materials does Waterweld bond to?\u003c\/strong\u003e Waterweld can be used with aluminum and fiberglass, and it is also suitable for automotive applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do you mix and apply JB Weld Waterweld?\u003c\/strong\u003e The putty is thoroughly kneaded with the fingers until it reaches a uniform color, then pressed firmly onto the surface being repaired;
