When it comes to using adhesives for any sort of repairs, JB weld comes to mind for many people. The company’s products excel at bonding between two parts of materials which is superior to most other brands.
However, while JB weld offers superior bonding for most materials, it’s not recommended to use on few items. This article will discuss whether JB weld works on plastics or not.
So, does JB weld work on plastic?
For many plastics, JB weld creates strong bonding to hold two pieces over time without bending. Again, it isn’t produced to work on some types of plastics those will be discussed below. The company has designed different epoxies to be used on different types of plastics for different situations.
Here’s a list of JB weld products that can be applied to different types of plastics:
|J-B Weld Plastic

How Well Does JB Weld Work On Plastic?
If you are searching for a reliable and long-lasting epoxy to be used on plastics, JB weld won’t disappoint you certainly. The company offers Plastic Weld that is available both as epoxy putty form and two-part liquid epoxy.
The epoxy putty is hand-mixable which forms a durable bond to almost all plastic types. After mixing, it forms a polymer compound. The compound can be molded or used to build up and repair just about anything made from plastic.
The Plastic Weld has 20-25 minutes of work life and the functional cure occurs in 2 to 3 hours. Once cured, you can saw, drill, sand, and paint on it.
The two-part adhesive, on the other hand, is a specially formulated epoxy filler system that provides for strong and lasting repairs. “Does JB weld work on plastic to metal?” If you have come across a question like this, the Plastic Weld syringe is here that bonds a variety of surfaces, such as metal, composites, fiberglass, and others. It sets in 5 minutes usually and is fully cured in 1 hour to deliver superior performance and quality.
If you are looking for an adhesive that would protect the wet plastic parts, JB weld has you back. The Water Weld epoxy putty is designed to work on plastic PVCs that would be underwater most of the time. The easy setup takes 1 hour of cure time. Then it delivers strong and long-lasting bonding between parts of plastics beneath the water.
Which Plastics Aren’t For JB Weld?
Well, does JB weld plastic bonder work on polyethylene? The answer is negative. The original JB weld products don’t work on polyethylene or polypropylene surfaces.
Polyethylene is used for water and gas containers largely. Polypropylene, being a harder plastic, is used for radiator parts of cars. The materials offer low-surface energies that make them non-stick surfaces for any sort of glues.
How Do You Use JB Weld On Plastic?
Applying JB weld on plastics demands clean surfaces that are free from oils, grease, dust, or ashes. Both the pieces need to be wiped out carefully so that no residue is left for the best welding performance. You can use alcohol or white vinegar while wiping to get rid of greasy films.
Next, you have to roughen the surfaces you want to bond together. Glues simply don’t last long on a smooth surface. Use sandpapers to roughen the bonding surfaces and clean the residue with a damp towel.
Once you’ve prepared the pieces to bond, it’s time to apply JB weld. The products come in two tubes. You have to mix them with hand in the same ratio to turn them into epoxy that creates bonding between materials.
Afterward, you have to apply the epoxy to the joining surface of the two pieces. Rub the mixture equally throughout the surface carefully.
Finally, arrange a way to hold the pieces together until the JB weld cures. The plastic material becomes usable like before when the weld is cured. Isn’t that really easy and straightforward?
Does JB weld work on ABS plastic?
That’s another common question I’ve got frequently. Acrylonitrile Butadiene Styrene (ABS) is made of an amorphous polymer. The thermoplastics can be heated to their melting points without getting burned. This property lets them to be molded and recycled rather than getting ruined under high-temperatures.
JB weld, being one of the most premium adhesives, works on ABS plastics too. JB weld Plastic Weld epoxy is designed for DIY plastic repairs on ABS plastics along with PVC and C PVC pipes and plastics.
1. Does JB weld steel stick work on plastic?
Ans: Yes. JB weld steel stick works on PVC and plastics along with Iron & Stainless Steel, Copper & Brass, Aluminum & Bronze, and Fiberglass.
2. How strong is a plastic weld?
Ans: If you prepare and apply JB weld properly on the plastic surfaces, it is expected to get back 98% of its previous strength after the weld is cured.
So, does JB weld work on plastic?
Most certainly it does. If you’ve chosen the right product for the right application, you can expect to have an excellent performance.
I hope you’ll find the best product for the purpose after reading my article. Let me know if you have anything more to know about the JB weld.
