Gorilla 100% Silicone Waterproof Caulk, Clear, 10 oz Cartridge

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.

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.

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.

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.

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!

It was caulking just as I ordered.90 sec in microwave salt and pepper it was filling.but be careful it may stop ya up.

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
