J-B Weld is the Original ColdWeld two-part epoxy, and it provides strong, lasting repairs to surfaces such as metal, wood, plastic, tiles, concrete, fibreglass and PVC. It is mixed at a ratio of 1:1, and forms a permanent bond that can be shaped, tapped, filed, sanded, and drilled after curing.

How strong is J-B Weld after 4 hours?

JB Weld QuickWeld is a fast-setting version of the original JB Weld. It sets in just 6 minutes and cures in 4 hours. It can be used on most materials, including metal, wood, plastic, ceramic, and more. It has a tensile strength of 3090 PSI.

Why is it difficult to weld aluminium?

Aluminium alloys pose a range of difficulties when welding, including: High thermal conductivity. This results in excessive dissipation of heat, which can make welding difficult and/or result in unwanted distortion of the parts, owing to a larger heat input being required.

Can you put 2 coats of J-B Weld?

JB Weld can be applied in layers. Just clean the surface thoroughly, apply the JB welding, and wait at least 8 hours to re-apply. When applying additional layers, it's important to wait to apply until the first application is fixed.

What is the fastest way to cure J-B Weld?

It's an epoxy, so should cure faster with heat. Another trick is to embed a piece of window screen in the putty to hold it until it sets up. x2 on the window screen, but heat, while making it cure faster will also tend to make it thinner until it starts tacking up.

What can J-B Weld be used for?
