Works Great, Just Dries with a Shine
I actually asked Alexa to help me find a caulk that dried without a shine, and this is what came up. When it cures, it definitely still has that glossy, shiny silicone finish, so it wasn't quite what I thought I was getting in terms of appearance. That said, Iโm not knocking any stars off for it because itโs still a great product that did the job well. The silicone applies smoothly, sets up fast, and creates a solid, watertight seal that holds up strong. If you need a reliable, waterproof caulk and don't mind the standard clear shine, this is good quality and gets the work done.

Gorilla 100% Silicone Waterproof CaulkโReliable Protection and Finish
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.

Great
This is very good product but unfortunately the gun I bought for it is a piece of crap and won't keep the tubing place.

Great caulking, goes on smooth
Great caulking, goes on smooth so application was pretty easy. Dries quickly as promised. The only thing is the very strong smell. I havent had it on the tub for very long so I cannot speak to it's versatility or how it stands up.

Gets the Job Done Even When You Don't Know What You're Doing
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.

Reliable, Fast-Drying Sealant That Lives Up to the Gorilla Name!
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 โ 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 โ better than generic brands and on par with premium ones like GE or DAP. It gets consistent 4.5โ4.8 star ratings across sites, and for the price (usually $10โ$15), it's a solid choice for home repairs. Highly recommended for anyone tackling wet areas! I'd buy it again in a heartbeat.

GOOD
Works good. I like the screw on cap, because if it dries up in the cap, you can unscrew it and poke it out.

Incredible 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.
