How to Remove JB Weld? (All Solutions Explained)

JB weld has been a top choice for both professionals and DIY-lovers alike. This two-part epoxy adhesive not only shows excellent performance but also withstands high-temperature. But once you have applied it, it is not uncommon to want to remove it if things don’t go well.

As this adhesive is one of the strongest glues, you might need a little help if you want to remove it. Today, I’ll be describing everything you need to know when you want to remove this glue. Stick with me until the end, and you won’t have to scrape the internet looking for ways to remove the JB weld glue anymore.

So, how to remove JB Weld?

There are three main ways. You can use liquid that contains alcohol or apply extreme heat. Forcefully removing using a grinder would work well too.

What Makes JB Weld Different From Others

Let us go through the basic mechanism of how glue works in layman’s term. Some substances that contain moisture are mixed with hardener, together they make the glue.

Once you put the glue out of its tube, reactions take place and the moisture slowly evaporates leaving the hardener to do the rest of the work. These types of glues are referred usually referred to as two-component adhesives or 2k or epoxy.

JB weld is an epoxy glue that has an equal ratio of resin and hardener. The resin and hardener have a very long shelf life. Yet when these are used to make glue the reaction starts as soon as they come in touch with the environment. As a result, the glue starts to solidify. It is the ratio that makes JB weld glue the top contender when you are looking for the strongest.

What Will Dissolve JB Weld?

No matter how hard JB Weld can get it has weaknesses just like everything in the universe. The answer might not be something you expected. Alcohol as solvent can dissolve this weld. The alcohol molecules when come in touch with the weld, they weaken the structure. The tougher solvent you can manage the quickly it will dissolve. Even then the process will be painfully slow.

A way to speed up the process is to apply heat when the weld is in the solvent. In short, you need to put the weld in alcohol, then heat it up. I would not recommend this procedure if you are not experienced, as accidents can occur if you are not careful.

How to Remove JB Weld

Mistakes are inevitable in this mortal world; it is even more so when you work with epoxy glues like JB weld. In case you need to remove it for some reason, let’s see what you should do. As the procedures vary, we will see how to remove this glue from different surfaces.

Removing from Metal:

There are mainly three ways to remove JB Weld from metal. They are extreme heat, grinding the epoxy and chemicals.

Removing jb weld with heat is a reasonable choice. If it is exposed to high temperatures like 600 degrees Fahrenheit, the glue would lose its integrity. A heat gun would be handy in this situation. Or, removing this adhesive with soldering iron is possible if the surface is small.

The mechanical force from the grinder can help you to get rid of it. Although you will have to be extra careful not to harm the structure. Also, if the material is resistant to vinegar or acetone you could try applying those. They are likely to soften the weld, then you can easily remove it with some force.

Removing from Plastic:

If you want to remove the glue from plastic, then try borrowing a trick we discussed earlier. As plastics are unlikely to withstand high temperature or grinding the best choice would be acetone and vinegar. You can also try applying thinner. They should make the glue soft enough to remove it with force.

Removing from the Skin:

If it is often that you get the weld on your skin then you should try out Fast Orange hand cleaner. It is readily available to use anytime, or you could try any hand cleaner you have nearby. If they don’t work then I would suggest using acetone or lacquer thinner. You can also use vinegar to remove the adhesive.

What Will JB Weld Not Stick To?

Even though as mighty as this weld seems, it cannot conquer everything. It is the flexible rubber surface that this one fails to fix. Even though it is completely resistant to gasoline, petroleum, water, and automotive chemicals, you won’t get positive results when used with rubber.

The main reason you can fix rubber with this one is that the rubbers are polymers. It cannot bond with this sort of substance.

So, in case you have anything that requires attaching rubber surface, don’t waste your time on JB Weld then. There are few other alternatives out there like Slime 1050 Rubber Cement for working with rubbery stuff.


Is JB Weld stronger than welding?

It is indeed as strong as weld if applied properly.

Is JB weld toxic?

When fully cured, it is not toxic. However, it is heavily recommended not to consume the product.

What do you use JB Weld for?

You can use it for almost anything you need to fix or repair. The list includes metal, ceramic, glass, steel, PVC, wood, fabric, etc.

Is JB Weld stronger than Gorilla Glue?

Yes, it is stronger than Gorilla Glue.

Is jb weld food safe?

Although it is non-toxic, it is not food safe.

Bottom Line

The JB weld is a very handy tool when you need something to repair. Even though it holds excellently even under harshest conditions, I would recommend against using any parts that are responsible for your safety. That being said, it is as important to know how to remove JB Weld as it is to know how to apply it. Mistakes happen, and when they do, it is better to have a way out than to be stuck with it.
