Gorilla100% Silicone Caulk, Waterproof Sealant, 2.8oz Squeeze Tube (Pack of 2) – Clear -10 Year Mold Resistant Kitchen, Window, Bath, Marine, Door and More

I used Gorilla Waterproof Caulk & Seal for a few small home projects—sealing around the kitchen sink and patching up a few spots in the bathroom—and I’m seriously impressed.The application was smooth and easy, even for someone who doesn’t do a lot of DIY. It comes out evenly, adheres well, and gives you just enough time to work with it before it starts setting. The clear finish dries beautifully and blends in seamlessly with any surface.What really stands out is how waterproof and durable it is. After a few weeks of daily use and exposure to water, the seal is still holding strong—no peeling, cracking, or discoloration. It’s also mold and mildew resistant, which is a huge plus in damp areas.Pros:Easy to apply and smooth outDries clear and cleanExcellent waterproof sealWorks on a variety of surfaces (ceramic, metal, glass, etc.)Mold and mildew resistantMinor Note:It has a bit of a strong smell when first applied, but it fades quickly as it cures.Bottom Line:If you need a reliable, waterproof sealant that’s easy to use and built to last, this is a fantastic choice. Gorilla nailed it with this one—definitely a product I’ll keep on hand for future fixes.

I recently recaulked my 1980's shower glass sliding shower door to the fiberglass insert with this stuff, and I was impressed. It was very easy for me to use - and WITHOUT a caulk presser machine thing. Ha!Once I got the old caulk off (actually pretty satisfying), I watched a YouTube video and conversed with ChatGPT about some specific questions, and then I was off! It took me almost 1 full tube on the shower door, so I'm happy that this 2-pack is offered.It dries much quicker than other brands, I learned. I didn't wait a full 24 hours, but it seemed to be cured enough (with the shower head pointed in the opposite direction just in case) within 18 hours.I've had bad luck with caulk before, and it always seemed so difficult unless you have the right tools, but this was EASY!

Effective but this smells very strongly.

This stuff works great!!. For anyone who owns a camp trailer you know that there’s always going to be some leaks and recently I had a leak in the seal of my roof that I was able to seal up just fine with this clear silicone. I have also used it all around the windows of my camper And it holds up well. I recommend having a tube available for those small jobs that pop up. It goes on easily and because it is clear, you can hardly see it. It makes a smooth and even line and easy to clean up if you do it before it sets. Helps to keep mold from forming from water leaks!!

I use this to seal threaded air lines on my semi truck. Takes about 20 min to solidify, no air leaks from any air line or fitting I've replaced yet. Some replaced air lines and fittings have been on the truck for 5 years now, with no leaks. The only "negative" is this stuff stinks. Have a rag or paper towel to wipe it off your fingers after you finish. Best way I found to apply it on the threads - take the cap off, then press the tip of the tube right on the threads and run it around while squeezing the tube. That way there's no mess. It doesn't matter if you don't run it all the way around the threads, once you start twisting the air line of fitting on the threads, it'll push the silicone around anyway. Good stuff.

I used Gorilla Waterproof Caulk & Seal Silicone Sealant for bathroom and kitchen repairs, and it exceeded expectations. The formula is thick enough to fill small gaps and cracks without running, making it easy to get a clean, solid seal. It adheres well, even on slightly damp surfaces, and dries to a smooth, professional finish. It’s been months, and there's no shrinking, cracking, or leaks. Perfect for anyone needing a reliable, heavy-duty waterproof sealant!

perfect for sealing the lenses on my offroad lights on my jeep and trucks. Note, to cut the tip for a small opening, does not need a very large bead with to do this job

I used a razor blade to cut and scrape the old Dap latex/silicone caulk joints on a fiberglass shower stall. I then used acidic bath cleanser (scrubbing bubbles) and a brush, followed be water rinse on the whole unit. I then used 90% isopropyl alcohol on a nylon scouring pad to clean and prep the areas to be caulked. I then used this to redo the joints. 24 hours later I did a cleanup of caulk on places I missed at application. I was surprised when I discovered the smears rubbed off with my finger. Doing that I pulled up the end of a bead. I was able to pull the entire bead out of the joint in one tear. Very little adhesion. So latex had no problem adhering but this does? I'm confident the surface was clean and dry. I've applied a lot of caulk in my days. I have no answer as to why this adhered so poorly. GE silicone is in there now and seems thoroughly stuck.
