About Gorilla Glue

Gorilla Glue is an industrial strength, waterproof polyurethane glue that claims to be suitable for indoor and outdoor use, and to bond to virtually any material, including wood, stone, metal, ceramic, foam, glass, and more. As such, Gorilla Glue claims to be incredibly strong and 100% tough for essentially any application you need.

Bonding two surfaces together can be a tricky process, and it’s admittedly difficult to formulate an adhesive that works across as many different surfaces as Gorilla Glue claims. So when it comes down to it, does Gorilla Glue actually bond as well as it claims? When should you use it, and when is something else a better choice?

Gorilla Glue Products

The Gorilla Glue Company, based out of Cincinnati, OH, manufactures a wide variety of industrial strength adhesives, the most popular of which is Gorilla Glue. This polyurethane-based formula is claimed to provide immense holding power by expanding 3X into the tiny folds and crevices of nearly any material, such as wood, plastic, metal, and much more. Gorilla Glue can also be sanded, painted, and stained, making it useful for almost any situation.

With this in mind, to use Gorilla Glue you’ll need to do the following:

  1. Clean the surfaces you’ll be applying Gorilla Glue to, and if necessary, roughen them up for better adhesion. Ideally, you’ll also need to dampen the surface.
  2. Apply Gorilla Glue evenly and sparingly, and spread with a disposable brush if necessary.
  3. Press the objects together and hold in place using clamps, a heavy object, or even rubber bands if small enough.
  4. Gorilla Glue will be 80% dry in 1-2 hours and fully cured in 24 hours. After using, store the glue in a cool, dry place.

In addition to Gorilla Glue, the company also manufactures a wide range of other adhesives in the USA, including Super Glue, Wood Glue, Epoxy, Clear Repair, Tape, and Self-Standing Bags.

Gorilla Glue Pricing & Refund Policy

Gorilla products are not sold through the manufacturer’s website, although their products are available from hundreds of third-party retails, which typically range in price between $3 and $72. As such, returns/refunds will be at the discretion of each retailer.

However, if you’d like to contact Gorilla Glue about questions or concerns, customer service can be reached at 800-966-3458.

What Do Other Consumers Have to Say About Gorilla Glue?

Overall, Gorilla Glue seems to have an overwhelmingly positive online customer reputation, although some of the most common complaints appear to revolve around glue drying inside the nozzle, thereby making it essentially useless after one application, high price when compared to the competition, and that it’s not well suited for small, detailed repairs. Also, while many customers like the fact that the glue expands into each surface, many others felt this caused a big, unnecessary mess.

Is Gorilla Glue the Best Option When Joining 2 Surfaces?

Given the fact that the DIY market is filled with all kinds of adhesives, does Gorilla Glue work as well as it claims? Should you use it for your next repair? Maybe, but remember the following:

Adhesion & Versatility

Based on customer reviews, while it appears that Gorilla Glue does have the ability to bond to most surfaces, it may not bond to every surface equally as well. As such, it seems that it bonds firmly to porous surfaces such as wood, although metal to metal seems to form the weakest bond.

On top of this, Gorilla Glue claims that it can be formed and shaped using sandpaper, a file, or even a Dremel, which can make it ideal for filling holes and cracks.

Relearn How to Use Glue

Do you normally apply as much glue as possible when bonding two surfaces? The more the merrier, right?

Not so with Gorilla Glue. Since it expands 3X in order to work its way into whatever surface you’re applying it to, it probably isn’t like any other adhesive you’ve previously used. As such, it’s important to use Gorilla Glue sparingly. Otherwise, you might have a big, sticky mess to clean up.

Also, compared to most “super glues,” Gorilla Glue has a relatively long bonding time, so it might not be ideal for last-minute fixes. And unless you’re gluing together 2 relatively heavy items, you’ll need to use clamps to achieve the best bond.

A Little Goes a Long Way

Since Gorilla Glue expands up to 3X, a little bit can go a long way. And because it comes with a relatively high price, you’ll probably want to purchase the smallest bottle you’ll need for your intended application.

Speaking of which: According to numerous customer reviews we encountered during our research, Gorilla Glue tends to dry inside the nozzle after only one use, making it essentially useless thereafter. This makes purchasing the smallest bottle required even more important. Tip: You can also cut a small portion off the tip to gain access to the glue each time you use it.

Bottom line:

For most applications, Gorilla Glue appears to be a strong adhesive that can permanently bond to most surfaces. However, it expands greatly and requires water to activate, so getting everything right might take some trial and error.

    Tried to glue toothpicks to plastic to shim a gap to a metal shive and it wouldn't bond toothpicks together.

    Waited 1 hour without any success, I've tried other Gorilla products with the same success, going to literally stick with lock-tight adhesive products.

  • Should be sold in little tiny single-use tubes

    Great glue, but no shelf life (bottle will harden after having been opened and it will be useless when you need it again). Regular white glue or thick crazy glue in single-use tubes is a better option.

  • Worthless Gorilla Glue product

    I have purchased a can of Gorilla Glue spray adhesive for use affixing labels to packages. What comes out of the can is mostly solvent with little actual adhesive. Once dry, I have actually had labels simply fall off the packages they were applied to. Heavier applications cause the printed label addresses to run until they are no longer readable.

  • Very happy customer

    I have used Gorilla Glue for a number of different jobs, including cork to spin aluminum, leather to plastic (sole to a shoe) and cloth to wood.

    As long as I followed the directions and didn't forget to slightly moisten the surface, I found the glue easy to use and very effective.

    I have not had the problems with the nozzle that others have experienced, probably because I am careful to replace the cap as soon as I have applied the adhesive.

    I love this product!

  • Overhyped and pretty useless

    Fell into the trap of believing the hype that this was the toughest glue on the market. Sadly, not so. Used two different Gorilla Glues for fairly straight forward jobs (mending a child's toy, and a DIY job). Used the "expanding" resin for the DIY job, and the "superglue" for the toy. The expanding resin was messy, took ages to bond and dry, and failed within a week. The superglue was a loooong way from "super", and (again) came apart within a few days. Plenty of better and more reliable glues on the market, so I won't be using the Gorilla brand again.

  • Worse than useless

    Tried using Gorilla Glue to fix a prop antler to its plaque, held antler in place for over 15 minutes, glue hasn't even started to set. Proceeded to remove antler from plaque again and attempted to clean glue off of both items, in spite of the glue still not setting AT ALL, this became a difficult task, the viscous fluid was difficult to mop away with a cloth and left a mildly stick (and not in a helpful way) residue on both items, resulting in a need to leave the items to dry overnight before I could attempt a more reliable method of adhesion.

    Gorilla super glue does not work. This glue takes a very long time to set for a super glue, in excess of 10 minutes on plastic. The bond that it forms is very week, in fact, totally useless.

    I tried to repair the broken leg of a pair of spectacles and this product was worse than useless.

    Best stick with the real Loctite Super Glue.

    Love the product but this glue sets with moisture and is really good for my jobs but the "squeeze" bottle SUCKS moist air back in which starts a film setting on the liquid and another inside the nozzle hole. This product is a scam because it guarantees you buy another before this one can be used up and the nozzle cap won't stop the suck-back forever, EH?

    I purchased Gorilla Glue clear 50ml to help with model making. What a complete waste of money. After 24 hours curing and being taped as recommended by Gorilla, the pieces just dropped apart. A problem which has never occurred before with other less expensive glues as this is costly compared to other competitors. I would not recommend this to anyone. I have tried it on different surfaces with the same result.

    So I would not purchase this again.

    Bottom Line: No, I would not recommend this to a friend

    Occasionally I will need an adhesive for something. What guy doesn't? Occasionally I make the mistake of getting Gorilla Glue products and curse my mistake EVERY TIME. From alternatives to small dropper super glue applications to spray adhesive, Gorilla Glue doesn't hold. I would probably get a comparable amount of adhesion from licking the two objects. I have never had an issue with JB Weld, Super Glue, Krazy Glue (not my preferred), even off-brand versions of the above. But Gorilla Glue? Never holds no matter what the material is. This is with me giving it pressure for 10 times as long as I do the others even.

    Buy at your own risk or just save the time and get any alternative. Elmer's school glue would do better.

    Bottom Line: No, I would not recommend this to a friend

  • Sucks

    I can't relay in words how much Gorilla Glue SUCKS! Does not adhere to anything but your fingers. I did exactly as the instructions indicated. I had others tell me it was awful but I had to try. Terrible product. Expands like "Great Stuff" spray insulation. Terrible product. Didn't even hold. Super Glue is a far superior product. I rely on quality gluing in my profession and Gorilla Glue is the worst of the worst. Negative 5 stars for this terrible product.

    Bottom Line: No, I would not recommend this to a friend
