Amazing glue. I love gorilla glue products and use a lot of it. It is the best glue out there. I know I tried all brands and this one by far is the best. Once you glue something it will never come off. So don't every plan on taking it off because it won't. So easy to apply. It seales evening out including water. I love the clear color. The smell is not that bad. Over dried there is no smell. I always use it to keeps the bugs out of my shed. It's a great barrier. Highly recommend.

This caulk worked great on my tub! The consistency was just right not too runny and not too thick which made it really easy to apply. It smoothed out nicely and gave a clean, professional-looking finish. I also like that it’s mold and mildew resistant, which is perfect for bathroom use. Overall, very easy to work with and the results came out looking smooth and neat. Definitely a great product!

The Gorilla Waterproof Caulk & Seal Silicone Sealant is a truly exceptional product. When you need a reliable, professional-grade seal that you know will hold up against the elements, this is the cartridge to reach for. The application is smooth, the gray color is clean and consistent, and the resulting seal is absolutely watertight and durable. It lives up to the Gorilla reputation for being tough and long-lasting—this is a 100% waterproof solution that provides real peace of mind for window and door projects. The only reason this isn't a five-star perfect rating is purely a function of convenience versus cost. I needed this caulk quickly for a weekend project and ordered it online. I have no doubt that I could have saved a few dollars if I had been able to go to my local hardware store to purchase it, but the quick delivery and knowing I had a premium sealant ready to go made the extra cost acceptable. If you prioritize quality and need immediate results without waiting for a trip to the store, this caulk is absolutely worth the investment. It’s a top-tier sealant that performs exactly as advertised.

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!

This is the best caulk I have ever used. It stays exactly where I apply it and almost behaves like adhesive caulk—perhaps it really is! At 68 years old, I have tried various types of caulk over the years, but the brands I used in the past have changed, and not for the better. The great thing about this caulk is that you can get it wet after about half an hour. If I could give it 10 stars, I absolutely would!

Ah, the Gorilla Waterproof Caulk & Seal 100% Silicone Sealant! Let me tell you, this stuff is like the superhero of sealants. It swoops in, capes flapping, and saves the day—no, scratch that—the entire week! Why Gorilla’s Clear Magic? Instant Bonding: Picture this: You apply it, and within 30 minutes, it’s ready for action. No waiting around like a wilting flower. All-Weather Warrior: Rain, shine, or snowstorm, this sealant laughs in the face of Mother Nature. It’s like the Chuck Norris of caulk—unyielding and impervious. Mold & Mildew? Not on Its Watch!: Gorilla’s got your back. No creepy crawlies setting up camp in your bathroom corners. Crystal Clear Brilliance: It’s like liquid glass. Transparent, glossy, and oh-so-sleek. Your windows, doors, and plumbing will thank you. No Yellowing, No Shrinking, No Cracking: Unlike that old rubber ducky you left in the sun, this sealant won’t age a day. The Gorilla Whisperer’s Tips: Sing to It: Yes, you read that right. Serenade your sealant. It loves a good tune. Name It: Call it “Silicone Steve” or “Sealant Sally.” Trust me, it’ll bond better. Throw a Mini Celebration: Invite friends over, raise a tiny toast, and say, “Cheers to leak-free adventures!” But Wait, No Recommendations? Oh, dear reader, I won’t push this on you. I won’t whisper, “Buy it now!” Instead, I’ll just wink and say, “You do you.”

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.

Very nice product

Can save a lot of money

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.

Nice product

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.
