JB Weld is an incredible adhesive that can stick literally any material together. It doesn’t matter if you are using it on steel, aluminum, plastic, or any other surfaces; this glue will create a strong bond for long-lasting results.
However, even though this adhesive forms a strong bond, have you ever wondered what type of surfaces JB Weld doesn’t stick to.

I bet you have. To help you understand, I have discussed what surfaces JB Weld will not stick to so that you refrain yourself from using it on those materials.
So, without any further ado, start reading!

Does JB Weld Work on Everything?
JB Weld is an extremely popular adhesive that is known for its strong bonding capabilities. It can be used to bond surfaces made from different types of metals, glass, fiberglass, marble, ceramic, wood, and others.
However, to your utter surprise, JB Weld isn’t compatible with all the materials and doesn’t work on every surface. While it creates super strong bonds on some, it simply doesn’t adhere to the others.
What Will JB Weld Not Stick To?
Now, if you are wondering where or on which surface JB Weld will not stick to, I have a list for you.
Go through the list below to learn more.
Rubber
JB Weld adhesives are not made for surfaces like rubber. And as they are not specifically designed for bonding rubber, these glues are not at all effective on any type of rubber and silicone surfaces.

It doesn’t matter how well you prepare the surface or how much JB Weld you apply, it just won’t work on rubber and hence, you shouldn’t try too.

A Few Types of Plastics
Even though there are more than a few types of JB Weld adhesives that work excellent on most plastics, like PVC, these glues don’t bond with a few types of plastics as well.
Some of the most common plastics that JB Weld will not stick to are:
Polyethylene
Polyethylene is a very thin kind of plastic that is mostly used in food and beverage packaging and medical devices and containers.
And as it is super thin, JB Weld will not form a strong bond with polyethylene. Therefore, you should refrain from using this adhesive on this type of plastic.
Polypropylene
Just like on polythene, JB Weld won’t work on polypropylene also. Even though it is a hard plastic, this adhesive will still not adhere to its surface and create a strong bond.
In fact, JB Weld is so unsuitable for polypropylene that it might crack the plastic when you apply it on the surface.

A Few Types of Metals
Although JB Weld adhesives provide the strongest bonds on steel, aluminum, and other metals, they also do not work on a few metal surfaces.
I have discussed about these metals so that you do not waste time bonding these metal surfaces with JB Weld.
Zinc

JB Weld adhesives don’t work on Zinc. As these adhesives are stronger than zinc, they might melt the surface instead of creating any bond.
Gold/Silver
Just like zinc, JB Weld adhesives are also not suitable to bond gold or silver. Because these glues are super strong, they may damage the metal even before you know it.
Glass Ceramic
Glass ceramic is a special type of material that is made using silica, alumina, and other compounds. Even though the composition seems strong, JB Weld adhesives aren’t suitable for this material.
They will not bond to the surfaces and might also damage it quicker than ever.
Will JB Weld stick to metal and plastic?
Yes, JB Weld is designed to adhere to both metal and plastic surfaces. It’s a versatile adhesive known for its ability to create strong bonds between various materials.
Just follow the manufacturer’s instructions for the best results.
Can JB Weld be used on painted surfaces?
JB Weld can be used on painted surfaces, but it’s important to prepare the area properly.
Clean the surface, lightly sand it for better adhesion, perform a small test if uncertain, apply JB Weld evenly, and allow it to cure as directed.
Keep in mind that the bond’s strength may vary based on paint type and conditions. When in doubt, consult the manufacturer or conduct a test.
Last Opinion
Now that you know what will JB Weld not stick to, I can assume that you will avoid this adhesive for bonding those materials.
It doesn’t matter how well you prepare these surfaces or how much glue you use; they will simply not bond together with JB Weld. You would need other forms of adhesives for these surfaces.
