Gorilla Waterproof Caulk & Seal Silicone Sealant, 10oz Cartridge (Pack of 1) - Clear Caulking Sealant for Kitchen, Window, Bath, Marine, Door and More

Been using this product for a long time on construction sites. Needed to glue down some plywood for a home renovation where we raised a sunken living room and these product did the job perfectly! Will continue to buy whenever needed! Just cut the tip, stab the seal, and start caulking! Works as intended.

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!

We had our shower replaced totally past the studs two years ago. The construction sealant used started to fail. Ordered this on a hunch. Cut out the old. Treated the areas with bleach. Let it dry thoroughly and applied your product. Very easy to use. Holding up quite well.

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.

It goes on bright white and stays that way after it dries. Easy to work with. It dries fast, so work quickly.

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.

It didn't stick to my smoth services. Had to remove all the services and start over with a different caulk. Brent

This stuff is great. Dries quick and stay white. The only con is the smell but its worth it once it dries. This caulk blows any other I've ever used out of the water. It is super bright white compared to others but I've ended up using it on my whole bathroom. Highly recommend buying this product

Very nice product

Can save a lot of money

Nunca había usado la marca, pero francamente me quedé asombrado por su calidad. Se adhiere bien a las superficies, además de ser muy buen sellador. Muy recomendable.

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.
