J-B Weld KwikWeld Cold Weld Epoxy 2 oz.

J-B Weld KwikWeld Cold Weld Epoxy is a fast-setting, two-part cold weld system designed to deliver a tough, lasting bond on metal, wood, ceramics, glass, concrete, fiberglass and many plastics. Whether you’re repairing a broken bracket under the hood, filling gaps in a ceramic vase or reinforcing a cracked countertop edge, this 2 oz. tube gives you shop-grade strength in minutes. With a simple 1:1 mixing ratio and no drawers-down wait time, KwikWeld lets you tackle urgent repairs and precision projects alike.

Once mixed and applied, KwikWeld sets in as little as 6 minutes, cures to a dark gray finish in 4–6 hours, and remains workable—meaning you can file, sand, drill or tap it to shape. The fully cured epoxy resists water, petroleum, chemicals and acids and withstands temperatures up to 300 °F, making it ideal for both indoor and outdoor fixes.
