It sets in 4 minutes and cures in 4-6 hours, while J-B Weld sets in 4-6 hours and cures in 15-24 hours. Because it is faster setting, KwikWeld has about two-thirds the strength of J-B Weld; however, they are both strong enough for most projects and repairs.

At room temperature, J-B Weld™ sets in 4-6 hours to a dark grey color. A full cure is reached in 15-24 hours. J-B Weld™ has a tensile strength of 5020 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.

Beside above, is JB Weld permanent? J-B Weld is The Original Cold Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces.

Consequently, can you make JB Weld dry faster?

“DRYING: Allow 4-6 hours for drying before handling. Allow to dry overnight (approximately 15 hours) before putting object to use. J-B WELD works faster if used in a room with a temperature above 50? F. After J-B WELD has cured for six hours, a heat lamp or light bulb placed near the weld will speed drying time.”
