Gorilla All Purpose Clear Silicone Sealant

This is a good, versatile sealant that lives up to the Gorilla brand's reputation for strength and durability. Being 100% silicone, it provides a completely waterproof barrier that remains flexible over time, ensuring it doesn't crack or shrink even with slight movement or temperature changes. The mold and mildew resistance makes it a practical choice for moisture-heavy areas like kitchens or bathrooms, helping to maintain a clean and professional look long after application. It applies smoothly and adheres well to a variety of surfaces, making it a dependable staple for both quick repairs and more involved home improvement projects. Bottom Line: A solid and effective all-purpose caulk. It is easy to work with, provides a long-lasting seal, and offers the reliable performance you need to keep your home projects well-maintained and protected.

Works great and dries pretty quickly. Used it indoors and started to skim in about 30 mins. Only bad thing is the strong sour smell when it’s wet and it is a pain to wash off fingers. This is normal for silicone caulk though and a sign it’s 100% silicone which is a sign of quality for waterproofing. Once fully dried to the touch after about 18 hours there was only the faintest sour smell that went away after another 12 hours and it’s fully clear which is great. Good quality for the price.

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.

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.

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!

I got this specifically to seal seams in my all-tile bathroom. The bathroom was renovated almost 7 years ago, so there were 7 years of showers, steam, hot weather, cold weather, etc. The tile holds up; the grout mostly holds up, but seams between planes tend to separate. The separations can be so small that you can't see them, but when someone spills a bowl of water near the corner of the room, it will, for example, show up as a leak on the ceiling of the room below. Hypothetically. <g> I learned a trick for getting a clean caulk line and ensuring the caulk makes full contact with the seams. I use a formica sample, but a credit card will do. It just needs slightly rounded corners. The other thing you need is a spray bottle with denatured alcohol in it. Apply a thin bead of caulk, then immediately spritz with the alcohol. The alcohol keeps the caulk from "setting up" too fast. Typically, people use their finger to smooth the caulk line. Don't do that! Use the credit card or formica sample to smooth the caulk line, wiping off excess caulk as you go along. The alcohol gives you extra time before it evaporates and the caulk gets messy. I did most of the places where the tile walls meet the tile floor, and in the shower where the walls meet at the corner. It's probably better to do it *before* there's a leak!

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!

You can’t go wrong with this silicone caulk. It works great and holds up well. You can’t paint it.

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.
