In this article I will show you some tips on how to remove JB Weld easily.
What is 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.
- The Original J-B Weld two-part epoxy cold weld system
- Great for household repairs, automotive projects, plumbing and marine applications, crafts and more
- Sets in 4-6 hours at room temperature and cures dark grey in 15-24 hours and rated at a tensile strength of 3960 PSI
Read on now to find out how to remove JB weld.
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.
- Trigger-start ignition easily ignites the flame
- Versatile webbed flame completes a variety of household projects, including small diameter soldering, thawing, melting and heat application
- Use only with propane fuel, such as the Bernzomatic 14.1 oz. Propane Hand Torch Cylinder
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.back to menu ↑
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.
