Gorilla Patch & Seal Liquid Rubber Waterproof Sealant, White, 32 Ounce (Pack of 1) - Seals Out Water, Air, and Moisture

Used this on my two sun windows on top of my sunroom. A huge leak appears around one of the windows after 19 years so I taped off around inside the window about a 1/4 inch in and applied the rubber sealer with paint brush on that 1/4 inch to the sunroom window frame and the leak stopped. A week later we had a 1 1/2 very hard rain and inside sunroom stayed dry. It painted on easily, had the lid off for 1/2 hour while using it and no dry ups in or around the can. It stuck to window and metal sunroom easily. It is thick enough to not cause run off as my sun room roof does tilt down. Great product.

Had a small leak at the edge of my roof.. Didn't want to use the thick black tar sealant Because it's the front of my house and I didn't want it that visible..Tried the Crystal Clear Gorilla Sealant and it was absolutely perfect.It was thin enough that after leaving unopened in the sun for the afternoon it poured easily out if the can - so all I had to do was spread it with a wide paint brush.. I repeated this over 2 days till the can was empty.It hardened after about 30 hrs & not 1 drop of water had gotten through it..It is somewhat visible from the road, but it just looks like a damp spot on that edge of the roof.Couldn't be happier..👍

I’m giving 5 stars because it works really well but there is a BUT, it is very difficult to apply using a roller, I used a foam roller and if your thinking it will apply like paint your sorely mistaken, I started with the spray cans but was getting pricey so I switched to this it’s very hard to work with it leaves clumpy build up but as long as you back roll it all lays nice and flat it goes on heavy so 1 coat only for me if it works, as well as the spray cans then it was worth the troubleForgot to mention that the cans were dented does take a long time to dry/cure been 2 days and it’s still slightly tacky, I used it on some concrete stepping stones loved the spray cans not sure about this stuff, if it dries thumbs up time will tell, water beads up nicely after using spray cans hope this acts the same way

Took a couple coats but for sure stopped my leak. Strong stuff.

This is an excellent product. I used it to repair the bottom in my lawn bag. Better than new. I will buy it again when I need a product like this and I would recommend it.

Can arrived all dented on all sides like it was used or as if it was returned many times. Paint itself is good.

Using this to patch a leak in a very old concrete fountain.Goes on clear. Dries shiny. Instructions say to mix but is it clear with no solids, so hard to tell when it is “mixed”. Goes on like paint but much thicker fluid. Be prepared to throw away your paintbrush after using - no way to clean it.Thick enough to adhere to the underside of a fountain with no dripping. Keep away from any water while curing. Dries to touch in about eight hours - even if coat is very thick.

This is the Best Product Ever!! If you have a Leak, this is the Product you need!! We used this on our roof and it hasn’t leaked any !!!
