If you have ever wondered if you can use JB Weld on your plastic projects, then this article is for you! JB Weld should not be used on any type of plastic because it will eat into the material causing damage which will make it unable to be repaired. That being said, there are plenty of other things that JB Weld can be used on besides your plastic projects! So let’s take a look at some alternatives to help you get your hands on that DIY project you have been itching to tackle.

Can Jb Weld Be Used On Plastic?

JB Weld is a two-part epoxy that is used to repair broken or cracked plastic. It is a type of adhesive that is sometimes used to fix things like water bottles and toys. JB Weld is not made to be used on plastic.

What Is Jb Weld?

1. Parts of the JB Weld Mix

The first step in using any epoxy product, including JB Weld, is to read through and follow the directions on the package very carefully. This will help you know how much product you will need and how long it will take for your epoxy to set up. There are two ingredients that make up the product: resin and hardener. The resin makes up about 70% of the mix and hardener makes up about 30%. The resin can either be clear or colored depending on what color you want your epoxy to be once it dries. The hardener comes in either a red squeeze tube or a blue one depending on what type of hardener you need to buy. You may want to purchase a hardener that will work in cold or hot temperatures depending on how you plan on using the epoxy.

2. Mixing the Epoxy

The next step is mixing the two ingredients together. This process will take a few minutes and you should try to keep your epoxy at room temperature during this time. Make sure that you mix them thoroughly in order for them to set up properly and for your project to turn out great! You can mix these two ingredients by hand, but if you are not careful, you may end up with lumps in your epoxy which will cause it to fail when drying. A better option would be using a drill bit or paint mixer and mixing it very well until there are no more lumps in the product.

3. Using JB Weld

JB Weld can be used on many different things like metal, wood, glass, ceramics and more. It is a great product to use on plastic projects because it is water resistant and will not yellow over time like some other products.

JB Weld can be used to repair cracked or broken plastic products, as well as make them stronger by filling in any holes or cracks that may have developed over time.

1. JB Weld is a Strong Bonding Epoxy

JB Weld is a bonding epoxy that will help you repair broken or cracked plastic products. The epoxy works great on glass, metal and many other materials, but will not work well on plastic. This type of product is thick and dense and needs to be used in a situation where there is not much movement or pressure being applied. The ingredients in the epoxy are designed to bond with different types of materials and will not hold up in a situation where there is a lot of movement or pressure being applied to it.

2. Using JB Weld

The best way to use JB Weld is by mixing the hardener with the resin part of the product first. After mixing them together thoroughly, you should then apply this mixture onto your project with a putty knife or other tool and spread it into place until it covers all cracks or holes that you want to fill in. You should then let this mixture sit for about 10 minutes before applying more layers of the epoxy until it covers everything that you want covered properly. Once this has been applied, allow your project to dry for 24 hours before using it again!

3. Is JB Weld Waterproof

JB Weld is not waterproof, so you should not get it wet! The epoxy will start to break down when it is in contact with water and can even start to dissolve if it is left in water for too long.

5. How To Get JB Weld Off Plastic

If you have accidentally gotten some of the epoxy onto a plastic surface, do not panic! You can use acetone or lacquer thinner to get the JB Weld off of the plastic surface that you want to remove it from. If you do not have these products available, you can use paint thinner instead. Make sure that whatever product that you choose does not contain water or any other chemicals because this could damage your plastic surface or cause your JB Weld to become loose and slide off of the project. Once you have removed all of the product from your project, wash off the area with warm soapy water and dry it before using again.

6. Can I Use JB Weld On My Glass Top Stove

JB Weld is not going to work well on glass top stoves because heat can get into the product and cause it to break down over time! If you need something that will help keep your glass top stove from breaking, try using a ceramic stove guard instead!


JB Weld may seem like a great way to get your hands on some DIY projects. Unfortunately, this product can be used on plastic, but it is extremely risky to use. Instead of using JB Weld, there are plenty of other alternatives to choose from. These include Gorilla Glue epoxy cement, Liquid Nails dripless nails adhesive, Hammerite vinyl glue, and Gorilla Glue waterproofing. Each of these products are designed to work on plastic and are very safe. They are also great glues to use for your DIY projects.
