100% Silicone Sealant Caulk, White, 10 oz Cartridge, 2-Pack | All Purpose, Long-Lasting Waterproof Seal, Fast Curing in 30 Minutes, Resists Mold and Mildew, Flexible and Durable

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.

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.

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.

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 picked up the Gorilla Waterproof Caulk & Seal in white (10oz cartridge) to redo the seals around my bathroom tub and a couple of kitchen windows, and it didn't disappoint. As a DIYer who's dealt with flimsy caulks before, this stuff is tough, easy to work with, and holds up well against moisture. Pros: Super Fast Water-Ready Time: It's ready for water exposure in just 30 minutes, which is a huge win for bathroom projects. I was able to use the shower the same day without worrying about leaks. No Shrinkage or Cracking: Unlike some cheaper sealants that crack after a few months, this one stays flexible and looks good long-term. It won't yellow over time either. Mold & Mildew Resistant: Perfect for humid areas like showers and kitchens – no mold buildup even after months of use. Excellent Adhesion: Sticks great to tile, glass, metal, and porcelain. I used it on window frames and tub edges, and it hasn't budged. Easy to Apply: Smooth consistency that tools nicely for clean lines. The 10oz cartridge gives plenty for multiple small jobs. Cons: Not Paintable: If you need to paint over it, this isn't the one (it's 100% silicone, so paint won't stick well). Strong Odor During Application: The vinegar-like smell is noticeable, so ventilate the area well. Cure Time: Full cure takes 24 hours, but the quick water-ready feature makes up for it. Overall, this is one of the best silicone sealants I've used – better than generic brands and on par with premium ones like GE or DAP. It gets consistent 4.5–4.8 star ratings across sites, and for the price (usually $10–$15), it's a solid choice for home repairs. Highly recommended for anyone tackling wet areas! I'd buy it again in a heartbeat.

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.

Worked as described ... setting time actually seemed to be way better then others I've tried in the past. Overall, great value.

Can save a lot of money

Nice product

This is my new go to bathroom sealant. I've tried all the others and as a contractor this one out performed them all. Shop around for the price as I've seen it cheaper else ware but nothing works better.

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
