Does J-B WELD Conduct Electricity? The Facts Explained


Anytime you’re working with electricity, safety is of the utmost importance. This means it’s crucial to know what tools and materials conduct electricity. One of the most popular epoxies on the market today comes from the J-B Weld Company, but is it safe to use around electricity, or will it conduct a current?

J-B Weld does not conduct electricity. As with most epoxies, J-B Weld is considered a good insulator that should not conduct electricity. It will also often perform better at bonding materials together at high temperatures than soldering alone might. Of course, there are other safety aspects to consider when using JB-Weld.

Now that we know that J-B Weld is generally safe to use around electric current free from the fear that it will conduct electricity itself, let’s look at a few other items that are worth noting when it comes to the epoxy. Be sure to read on below as together we will look at how to use J-B Weld safely around electricity, some pro-tips for using J-B WELD correctly, and what to avoid at the same time. All that and more coming up next!

Is J-B WELD Safe to Use Around Electricity?

While J-B Weld should be safe to use around electricity, in general, any home improvement projects that involve electric work should be done by a certified professional, especially if the homeowner is uncomfortable undertaking such work or has little experience working with a home’s electrical system safely. 

Working with J-B Weld is much like working with any epoxy and electricity. As long as some simple rules are followed, everything should be fine:

Turn Off the Current at Your Breaker Box:

Whenever you are undertaking any electrical work around the home, the first thing you should do is turn off all electrical current directly at the source, your breaker box. Cutting off all power will give you the peace of mind that is required to undertake electrical work without having to rely on a previous owner’s labeling system.

Be Cognizant of the Temperature 

Are you going to be applying your J-B Weld in a high-temperature area? Normally this should be fine, as J-B Weld, like most epoxies, does very well in high-temperature situations. 

Most normal epoxy can handle heat between 68- and 195-degrees Fahrenheit, J-B Weld can handle up to 500 degrees Fahrenheit. If the temps you are dealing with may regularly exceed this, it may be better to go with an epoxy rated for high temperatures.

Don’t Force It

If you have done everything right in terms of preparing the surface for using your J-B Weld and you still don’t feel comfortable applying it, don’t do it. There is no need to force it if you are unsure if you are undertaking the proper fix. Consider your problem again, consult an expert if necessary, and attack your issue anew when you feel up to it.

And there you have our three keys to always keep in mind when working with J-B Weld around electricity. Next, we will focus on further advice for general J-B Weld use, be sure to read on below to ensure optimal results with your project.

Tips For Best Results When Using J-B WELD

The following are a few basic tips that will make using J-B Weld a breeze and have you finishing your projects like a pro.

  • Prepare the surface: Like any epoxy you use, J-B Weld will be most effective when it is applied to a clean surface free from dirt or residue. Avoid any alcohol-based cleaners that may leave petroleum residue behind, use an acetone or lacquer thinner instead. If you don’t have these items, simple soap and water will do. Make sure the area is completely dry before J-B Weld is applied. 
  • If you need a quick setting epoxy, consider something else: J-B Weld is a great product, but it can take up to 6 hours to set up. 
  • Let the product cure properly: Similar to the time it takes J-B Weld to set, the curing process for the product can take up to 24 hours. During this time, it is best to avoid disturbing the bonding process, as this can permanently weaken the hold that the epoxy can provide.

So, now that we know a few things we can do to help make our projects go right let’s next look at pitfalls to avoid when using J-B Weld.

Problems to Avoid When Using J-B WELD With Electrical Projects

While J-B Weld is an easy-to-use and consumer-friendly product, that doesn’t mean that there aren’t problems that can arise from its misuse. Below we have highlighted a couple of such issues that can crop up that are best avoided when it comes to your use of the epoxy.

  • Adhering to unsuitable materials: In addition to our tips above, it’s best not to try to use J-B Weld for bonding between incompatible materials or surfaces. Such materials that J-B Weld will not adhere well to include leather, vinyl, canvas, plastics, and rubber surfaces.
  • Beware of high temps: Do not be fooled into using J-B Weld in consistently high-heat environments, such as in a car’s engine or exhaust system. The temperatures in these areas are too high for too long for the product to remain effective. A high heat epoxy rated for at least 450 degrees Fahrenheit is recommended.
  • Once it’s cured, it’s stuck: Removing your J-B Weld can be a major pain in the butt after it’s set and cured. Doing so requires filling away at the epoxy or hitting it with extremely high temps, neither of which is pleasant. For this reason, it is always best to be certain you have your J-B Weld where you want it BEFORE it cures!

Avoiding the above mistakes when it comes to J-B Weld use should help ensure its proper use and a smooth project for any homeowner.
