J-B Weld

Although it sounds like being a real metal weld, it actually isn’t.

J-B Weld is a cold weld two-part epoxy glue. (Homepage)

It helps to repair metals and different surfaces through a permanent bond.

Curing the liquid weld is done at room temperature in 15-24 hours. When completely cured, J-B Weld will withstand temperatures up to 550°F.

As an alternative to epoxy glue try welding with a MIG welder. Real weld seams will withstand much higher temperatures. Of course, you should not glue safety critical parts (like car frames), anyways.

How to remove JB Weld?

Apply extreme heat to JB Weld

The easiest way to remove J-B Weld is to heat it up with a propane torch. JB Weld does not withstand more than 600 degrees Fahrenheit [Source].

High heat will damage the internal chemical structure which means, the glue will get off a lot easier. To get started, use a torch with a low flame and heat the material up. Once the temperature goes above 600 degrees it will come off. Moreover, you can help with mechanic force and scrape or brush it off.

Another possibility for small areas is to use a soldering iron. Although for bigger parts and large areas this will take too much time until the glue is completely hot.

Grinding the cured epoxy

If you don’t have a heat source, you can also try mechanical force with a grinder. Use a tool like an angle grinder, a Dremel and sandpaper to completely remve JB weld. When grinding, please make sure to wear a mask or respirator to avoid inhaling the dust, because it can be dangerous.

Remove JB Weld with chemicals

Although we have not tried this ourselves, some people were reporting that chemicals like vinegar and acetone made the weld soft and helped to remove it.

I’d recommend not to mix techniques because applying chemicals and grinding at the same time will result in a huge mess.
