Gorilla Spray Adhesive vs. 3M 77

The Gorilla and 3M 77 spray adhesives are permanent, durable and can be used on a range of materials. But the Gorilla adhesive is more affordable than 3M 77.

Key Takeaways

  • The Gorilla spray adhesive is a permanent adhesive suitable for painted and unpainted surfaces.
  • The 3M 77 is also permanent, dries faster, and has a higher temperature resistance.
  • The 3M 77 is slightly more expensive than the Gorilla spray adhesive.

Gorilla and 3M are two of the most popular names among all the available spray adhesive brands on the market.

That’s why I have compared the Gorilla spray adhesive vs. 3M 77 for today’s article.

So feel free to stick around until the end!

Overview of Gorilla Spray Adhesive

The Gorilla spray adhesive is a permanent and durable sealant for heavy-duty applications.

It is made with advanced adhesive technology to repair and seal a vast range of materials at any temperature.

With its clear form, this adhesive is easy to conceal on any surface, and you don’t have to worry about it turning yellow due to exposure.

Overview of 3M 77 Spray Adhesive

3M sells a range of spray adhesives. And the Super 77 is one of the best-selling ones due to its ability to bond most objects and materials.

Along with its fast drying ability, the 3M 77 offers better coverage thanks to its nozzle mist spray pattern.

This spray adhesive is reliable for use both indoors and outdoors, and it doesn’t turn yellow either.

Gorilla Spray Adhesive Vs. 3M 77: Features Comparison

Adhesive Formula

The Gorilla spray is an ethylene-vinyl acetate adhesive and contains acetone, methyl acetate, cyclohexane, etc.

Thanks to that, this sealant offers a durable performance, adheres faster with a colorless texture, and works on painted and unpainted surfaces.

And the 3M 77 comes with a synthetic elastomer base formula, which is known for its robust performance.

On top of that, such adhesive material is highly reliable for use on porous and non-porous surfaces.

Application Type

Both Gorilla and 3M 77 are spray adhesive. They come in aerosol cans in gas form.

And the cans have attached nozzles for easy and even spraying.

Compatible Materials

The most impressive part of both of these adhesives is that they work on materials beyond your expectations.

Take the Gorilla spray adhesive, for example. It can be used on a variety of materials, such as plastic, metal, wood, fiberglass, fabric, leather, paper, etc.

Quite similarly, the 3M 77 works on a range of materials, such as fabric, paper, leather, foam, wood, cardboard, plastic, metal, glass, etc.

Weather Resistance

Because these adhesives are water- and temperature-resistant, they are suitable for use indoors and outdoors.

The best part is that they won’t turn yellowish due to exposure to the sun.

The Gorilla spray adhesive can resist temperatures up to 130°F. However, I must add that the Gorilla adhesive is slightly sensitive to moisture.

But I had no such issue with the 3M 77 as it can resist temperatures up to 150°F.

Drying and Cure Time

Usually, the Gorilla spray adhesives dry within 1-3 minutes.

But in some cases, it can take up to 10 minutes to dry completely.

On the other hand, the 3M 77 dries a lot faster, taking only 15-30 seconds in most cases.

The highest it takes is 10-15 minutes, which is pretty rare.

And though they harden and cure within a few hours, I advise waiting at least 12 to 24 hours to let them cure properly.

Strength

These adhesives don’t compromise when it comes to bonding materials.

Both Gorilla and 3M 77 offer a strong and durable bond in most cases.

Convenience

One of the advantages of using Gorilla and 3M spray adhesives is that they are very convenient.

The spray application feature minimizes mess and offers a more controlled application.

On top of that, they have a longer shelf life, which allows you to use these sealants later.

Besides, the nozzles don’t usually get clogged, unlike low-quality adhesives.

However, you must store them on the recommended surface and temperature.

Popularity

Even though both Gorilla and 3M are popular brands, the user ratings and feedback for these spray adhesives are very different.

Turns out, users like the Gorilla spray adhesive more than the 3M 77.

I would say the difference in cost is one of the factors behind it.

Cost

Despite its high-grade components and top-notch adhering quality, the Gorilla spray adhesive comes at an affordable price.

For example, a 14 oz Gorilla spray adhesive can cost around $12.

On the other hand, the 3M 77 is slightly more expensive as a 13 oz can often cost around $14.

However, the price often varies depending on various factors, such as can size (it affects the cost per ounce), location, availability of the adhesive, discounts or offers, etc.

Which One Is More Durable?

When it comes to durability and long-term use, both Gorilla and 3M 77 get all the points. 

All the projects I used them on are still doing just as great as ever.

However, it is best not to use the Gorilla glue outdoors where it will be exposed to humidity or moisture.

As I mentioned before, this glue isn’t exactly the best when it comes to dealing with moisture.

Editor’s Opinion

Comparing the Gorilla spray adhesive vs. 3M 77 and choosing only one is a tough battle.

But the Gorilla spray adhesive is more convenient if you want a sealant that will give you enough time to reposition the material.

Moreover, it is more affordable and widely available compared to the 3M 77 sealant.
