This is a sealant and adhesive that will serve you well in just about any scenario. Able to work on just about any surface, this is the sealant you’ll want to keep in your house or on your boat. A clear dry, the only tell that this sealant caulk was even used is the fact that whatever it is that you used it for, it won’t be coming apart or leaking soon.

Who Is This Product For?

In short, this product is for anyone that needs a strong adhesive and sealant. Be it for a DIY project you’re looking to do, or a simple repair job you need doing around the home, this sealant will serve you faithfully and dutifully. It can also work very well in the bathroom, acting as a sealant between tiles. Its waterproof nature makes it excellent for this job.

What’s Included?

When making your purchase, you can expect a tube of Gorilla 100% Silicone Sealant Caulk and an additional nozzle with a finer point. Nothing else comes with the purchase, and you need not purchase anything further, thanks to how user-friendly its use is.

Overview of Features

As stated earlier, Gorilla makes incredibly strong adhesive products, and this is an excellent example. It is its strength that makes it so versatile, able to withstand high levels of punishment and resist the elements. This makes it suited for both indoor and outdoor use, and on any surface, regardless of how rough or uneven, it may be.

Its versatility comes in when you try to find a use for it. Able to work on just about any surface, no matter how uneven, or whether it is indoors or outdoors, Gorilla 100% will do the trick. The only material it loses its effect on is wood, for which we recommend Gorilla Wood Glue, another of their products.

But while it comes within a hair’s breadth from it, it isn’t perfect. Its one major downside is that it isn’t the best for when it comes to sealing, repairing, or gluing wood. For woodwork, it is recommended that you instead use Gorilla Wood Glue. Otherwise, Gorilla 100% Silicone Sealant Caulk will be gold.

How To Use It

As with any other sealant of this type, applying it is secure. You would use it as you would any other glue, gently squeezing the adhesive out the tube onto the area you want to seal and then spreading it as needed. It dries clear and can be easily cleaned with solvent, so you don’t have to worry about accidentally going overboard.


  • It is completely clear once it has dried
  • Entirely waterproof for use in the bathroom and kitchen
  • Resistant to weather and moisture, meaning you won’t get mildew and mold
  • Incredibly durable, able to withstand much punishment, making it great for indoor and outdoor use


  • Not very good when working with wood
  • Cannot be removed with water, requires solvent instead


While it is a very popular sealant and can see you through any task, there are a few alternatives that can help you get around the one major negative of Gorilla 100% Silicone Sealant Caulk

Anti-seize RTV Silicone Sealant

Anti-seize RTV Silicone Sealant is a fantastic sealant and one of the few that can outclass Gorilla 100% Silicone Sealant Caulk. This is because it can work with any material, including wood. It has many of the same features, being waterproof, transparent, and resistant to almost all damage. Its only weakness is torque damage, which causes it to crack and peel. Otherwise, if you won’t be working with wood, Gorilla 100% Silicone Sealant Caulk is the way to go.

Gorilla Wood Glue

If you don’t want to break your loyalty to Gorilla, or don’t want to invest in a different sealant simply because of wood, perhaps invest in Gorilla Wood Glue. While not an alternative exactly, it works well alongside Gorilla 100% Silicone Sealant Caulk and covers the only weakness that it has: not working well on wood. This allows you to cover all bases and work with any and all materials, including wood.

Final Thoughts

An all-around excellent adhesive and sealant, Gorilla 100% Silicone Sealant Caulk will quickly become your best friend for all your adhesive needs. Incredibly robust and versatile, you can use it on just about any surface, and for those that you can’t – namely wood – there are easy workarounds. Gorilla 100% Silicone Sealant Caulk is a top of the range adhesive that delivers quality.
