JB Weld vs Gorilla Glue

JB Weld vs Gorilla Glue

Whether you are looking to complete some construction projects, you need to repair some broken things around the home, or you are doing some arts and crafts, one thing that you can always make good use of is some great glue.

With that said, finding the right kind of glue is very difficult, no doubt because there are so many different kinds out there, not mentioned many different brands as well.

What we want to do today is to compare two of the most popular glues out there, JB Weld and Gorilla Glue. Let’s get right to it and figure out which of these two products is the best one for you to use.

JB Weld Gorilla Glue

Makes a mess during use and is difficult to clean up

Non-toxic formula

The primary application of Gorilla Glue is for wood gluing

Porous materials only

Very high bond strength, but not quite as high as JB Weld

Very little flexibility

This glue is resistant to the same things as JB Weld, but just not to the same degree

JB Weld Review

Jb weld glue

First of all, we have JB Weld which is a very special type of glue. Technically speaking, this is a two part epoxy. One part is the resin. The actual stuff that turns into plastic once it dries and the other part is the hardener.

Do keep in mind that the resin and the hardener need to be mixed together before use and you will only have a few minutes to use it before it begins to set.

Now what is really cool about JB Weld? As you can maybe tell by the name of it, it is steel reinforced. Yes that is right, this stuff has actual steel in it so when it dries it becomes as strong as metal or at least almost as strong. JB Weld has an insane tensile strength of nearly 4000PSI, which is more than most other glues out there.

Moreover, this is also one of the best guns out there because it is waterproof petroleum proof, chemical proof and acid resistant. There are virtually no solvents that can get rid of this stuff once it is dried.

Moreover, once it is dry it is completely nontoxic and it can even resist temperatures up to 500 Fahrenheit, which is totally insane. What’s also cool about this product is that once it is dry, it can be drilled, tapped, sanded, machined, filed, and painted. This is a perfect product used for a variety of construction projects, repairs, arts and crafts, and much more.

Gorilla Glue Review

Gorilla Glue

Something to keep in mind here is that there are many kinds of Gorilla glue out there, but the one we’re talking about today is the original one, the one that is made out of polyurethane.

In other words, Gorilla Glue, the original one, is a polyurethane adhesive. A very important thing to remember here is that this type of Gorilla glue needs to be exposed to the moisture in the air in order to dry and cure.

Now what you might not know is that this type of glue polyurethane glue is most commonly known as what group it is. A yellow type of glue that bonds very well to porous surfaces such as wood. With that being said, this glue can also be used to bond other porous surfaces such as papers, fabrics, porous metals and other such things.

What is important to note here is that Gorilla Glue takes a full 24 hours to dry and cure, which means that you will need to clamp it. This stuff does have a pretty high bond strength, although not quite as much as JB Weld, but what is beneficial here is that this stuff is extremely water resistant. Yet another thing that you might like about this glue is that it spreads out and it expands as it dries, thus allowing for pretty good gap filling capabilities.

Comparing JB Weld vs Gorilla Glue

Now that we have figured out what both JB Weld and Gorilla Glue are, it’s time to compare them on a side-by-side basis. Right now, we want to compare JB Weld and Gorilla Glue based on what applications they can be used for the materials they can bond with, how strong the bond is, how easy they are to clean up, what safety concerns they come with, and more.



In terms of the applications, the number one thing that JB Weld glue is used for is for making repairs.

The reason for this is because JB Weld glue has an extremely high tensile strength of nearly 4000PSI. There is also the fact that it is waterproof petroleum proof, solvent acid and chemical proof, which means that no matter what repairs you make, they’re not going to come undone anytime soon.

There’s also the fact that this stuff is very temperature resistant, and it can be worked with once dry, including sanding, painting and more. Just keep in mind that this product does cure dark grey, so you can’t really use it for anything artistic or for anything that needs to look really nice afterwards, That is unless you decide to paint it after.

Gorilla Glue is very different in this sense as it is technically a type of polyurethane glue and is therefore a type of wood glue.

Therefore, as you can tell, the main application of Gorilla Glue is wood gluing. This could be in carpentry, for wood repairs, or for any other such purposes. That said, Gorilla Glue is also perfectly capable of bonding other porous materials, so it can be used for various arts and crafts and for small repairs.



What’s really nice about JB Weld is that it is such a versatile type of epoxy. This stop can be used to bond virtually any and every material together with the reason for being that it works on both porous and non porous materials.

This means that JB Weld is ideal for bonding wood, paper, fabrics, plastics, metals, beads, jewelry and so much more. There really isn’t any kind of material that JB Weld can’t bond together with extreme prejudice.

On the other hand, we have original Gorilla Glue. Due to the fact that it is a polyurethane glue, its primary purpose is for gluing wood together.

That said, it is capable of bonding various porous materials, such as papers, fabrics, and other such things. However, something that Gorilla Glue cannot do is the bonding of nonporous materials. It needs porous materials to adhere too, so it can’t handle things like smooth metals and plastics.



OK, so if you’re looking to bond what together then Gorilla Glue is probably your better option. However, with all of that said, in the grand scheme of things, JB Weld definitely has way more holding power.

It has far higher tensile strength and gorilla glue, and it’s far more resistant to a variety of factors. Now this is not to say that Gorilla Glue is not waterproof or that it is susceptible to solvents, but it’s just not quite as strong as a two-part epoxy such as JB Weld. The bond created by JB Weld is nearly impossible to break and this is true both in terms of impacts and solvents as well as temperatures too. At the end of the day, JB Weld is just far more resilient against various elements than Gorilla Glue is.

However, do keep in mind like a real blue is much easier to work with because you don’t need to mix it. JB Weld is a two-part epoxy, which means that you first need to mix the two together. Although the bond is much stronger, it’s also harder to use, and it makes quite a bit of a mess as well.



When it comes down to it, neither of these products are very easy to clean up, and it’s because they are such strong glues. With that being said, Gorilla Glue doesn’t require you to mix 2 separate components together, and it’s this costly means that it doesn’t run too much.

Moreover, once Gorilla glue dries, although it is nearly impermeable to water in solvents, it is a bit easier to clean away than JB Weld.

The thing you have to remember with JB Weld is that you have to mix those two components together first and that automatically makes a bit of a mess. Moreover, once JB Weld drives you will be hard pressed to find any kind of solvent or method that will be able to remove it.

Health Warnings

Comparing JB Weld vs Gorilla Glue

What needs to be noted here is that JB Weld has a nontoxic formula. Now it’s obviously not healthy to ingest but if you do happen to ingest a bit of it won’t kill you. Gorilla glue, on the other hand, has expressed safety warning warnings that say that you can in no cases ingest it. Gorilla Glue is extremely poisonous and may lead to death if enough of it is ingested.

Differences Between

Let’s take a quick look at the main differences between these two products.

  • JB Weld is a two-part epoxy whereas Gorilla Glue is polyurethane wood glue.
  • JB Weld can handle both porous and nonporous materials whereas Gorilla glue can only handle porous materials.
  • Really, glue dries to a yellowish colour, whereas JB Weld rise with a grayish colour.


Is Gorilla Glue heat resistant?

Gorilla glue is heat resistant, although not to the same extreme temperatures as JB Weld.

What is Gorilla Glue used for?

Gorilla Glue Original is mainly used as a wood glue, although it can also handle paper fabrics, another porous materials.

What is JB Weld best used for?

JB Weld is best used for making various serious repairs around the home.


At the end of the day, it’s nearly impossible to say which of these Blues is better, because they’re both very different glues with extremely different purposes. It really not the same thing at all. If you need something to glue wood together and Gorilla glue is the way to go, and if you need to make some serious repairs, then JB Weld is the way to go.
