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.

This worked great for my husband. He said it applied well and sealed things up just right. So it was good quality for him, and it dried well too.

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.

Works amazing. Strong hold. Easy to work with

I used this to seal the shower doors in both bathrooms. It wasn't my first time caulking, but I learned very little from previous attempts, and the mess I made this time was entirely reflective of that. I still don't know how to stop the caulk from oozing out of the gun once I release the trigger, so I over-applied generously and left excess everywhere. One cartridge still covered both doors, which is impressive considering how much material I wasted. The seal itself is great. It goes on and dries pretty clear, cures within the 30 minutes the label claims, and I've had zero leaks. No discoloration or cracking so far either. There's visible excess well beyond what was necessary, but I'm not about to trim or scrape it away because everything is sealed tight and I'd like to keep it that way. I'm confident that if my sloppy first attempt works this well, someone with a modicum of skill would find this stuff an absolute dream to work with.

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!

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.

Recientemente lo use y funciono bien, seco un poco mas rapido que otros productos con los que tuve problemas para que curaran

Applied for 1 week now, working well and no water leakage
