Great Silicone, The BEST!!
Gorilla products are the absolute best! Used around the inside of our bathtub and is working as a champ of course. Going to be getting more Gorilla products to go around our windows where needed.

Strong, Reliable Seal & Easy to Use
I used the Gorilla Waterproof Caulk & Seal Silicone Sealant for a few spots around my bathroom tub and kitchen sink, and it performed exactly as advertised. The sealant goes on smoothly with a steady bead, sticks well to tile and metal, and cures into a flexible, waterproof finish that feels tough and long-lasting. I love that it’s truly waterproof once set — no shrinking or cracking after a few days of showers — and cleanup was simple with just a damp cloth before it dried. Ideal for bathrooms, windows, doors, and even small outdoor jobs. For anyone needing a dependable sealant that holds up to moisture and everyday wear, this Gorilla silicone is a solid choice!

product works, just make sure you wipe the excess off before it dries/sets
For those of you who aren't expert caulkers don't make the same mistake I did--I went through the trouble of using painters tape to get crisp lines, BUT I didn't wipe the excess off after 30 minutes...I think I waited much longer than that not thinking of the consequences. Well to my huge disappointment I pulled the painters tape off days later expecting a perfect finish but instead I realized the thin excess of caulk that was on the tape clung on so crazily hard that it just remained connected/fused to the main line of caulking if that makes sense. It does not behave like excess paint on painters tape if you get what I mean. I ended up having to razor blade off the excess caulk thus making the whole thing into an ordeal, which I may end up having to redo way sooner in the future. ugh. Minus one star because it smells pretty bad but otherwise the product is what it says it is.

Excellent product
We had our shower replaced totally past the studs two years ago. The construction sealant used started to fail. Ordered this on a hunch. Cut out the old. Treated the areas with bleach. Let it dry thoroughly and applied your product. Very easy to use. Holding up quite well.

Smells like hell. Works well. A bit hard to squeeze, but even flow. Looks great, much more clear than the last one I tried and the skin forms better than some others in my opinion. Easy clean up. Just wish it didn’t feel like I was gassing myself out or having to use two hands to get any product

Small size, big price
It works great, but its very difficult to smooth out, nearly dries instantly and becomes impossible to maneuver or work with. very expensive for the small bottle you get. if doing your tub, you will need 2 bottles minimum. looks nice, came in white so not clear, small size.

Nunca había usado la marca, pero francamente me quedé asombrado por su calidad. Se adhiere bien a las superficies, además de ser muy buen sellador. Muy recomendable.

We used this to try to fix the lint trap on my dryer. The metal screen was rusting and tearing along the edge. No way to replace the screen or purchase a new lint trap. One bad of silicon asking the torn edge and seems to work perfectly fine.
