    • Amazing glue. I love gorilla glue products and use a lot of it. It is the best glue out there.
Color: Clear Size: 2 Pack
Amazing glue. I love gorilla glue products and use a lot of it. It is the best glue out there. I know I tried all brands and this one by far is the best. Once you glue something it will never come off. So don't every plan on taking it off because it won't. So easy to apply. It seales evening out including water. I love the clear color. The smell is not that bad. Over dried there is no smell. I always use it to keeps the bugs out of my shed. It's a great barrier. Highly recommend. ... show more

    • GREAT PURCHASE FOR BATHROOM CAULKING!
Color: White Size: 1 Pack
This caulk worked great on my tub! The consistency was just right not too runny and not too thick which made it really easy to apply. It smoothed out nicely and gave a clean, professional-looking finish. I also like that it’s mold and mildew resistant, which is perfect for bathroom use. Overall, very easy to work with and the results came out looking smooth and neat. Definitely a great product! ... show more

    • Gorilla Waterproof Caulk & Seal: Premium Quality When Time Matters
Color: White Size: 1 Pack
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. ... show more

    • Strong, Reliable Seal & Easy to Use
Color: White Size: 1 Pack
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! ... show more

    • Reliable, Fast-Drying Sealant That Lives Up to the Gorilla Name!
Color: White Size: 1 Pack
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. ... show more
