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

Very good rubber coating, great value, used on underside of enclosed trailer, very good adhesion from rolling on, very thick after 2 coats

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

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.

Used yesterday on a corrugated roof! went on easy will have to wait for first rain but applied easily and seamed to solidify nicely.

Very thin stuff, kinda whimper. Maybe it works for some applications, im not sure. Doesn't seem to really adhere all that well...but I just used it on some pvc pipes. Can had a large dent in it and the can appears to be made out of very cheap metal so if you attempt to put lid on to keep fresh , it just even stand up to some normal taps with hammer to reseal lid , like what's everyone does with a paint can.

This is definitely a great product for weatherproofing and sealing almost any surface! Ready to use right off the can: just pour or apply with a brush and it dries into a clear hard (a little rubbery) finish in about one hour. It can even be applied in moist surfaces as it displaces water drops while being applied. However dry clean surfaces have a better finish result.The downside is that the contents start to solidify as soon as it comes in contact with air. Meaning, once you open that can some of the product will turn into a trasnparent gel. This will result in some product loss even if you try to seal tightly.Overall, I highly recommend this for quick, easy and effective waterproofing.

Do not purchase from Amazon. I'm sure this product is great but purchased TWICE from amazon and both times arrived dented, not able to close and with paint dry on the inside. It is sticky and messy so I went with the spray one and it does NOT seal the same finish. The spray is matte while the can is shiny and slippery. I recommend getting this in person. Have no doubt it would be actually good.
