Gorilla Patch & Seal Liquid Rubber Waterproof Sealant, Black, 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

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

Love the easy application. this worked great at keeping out moisture that was coming in through our exterior wall that is also a SEA WALL!. Don't ask... building codes in the middle of the pacific, not so much! We needed to keep water from intruding and the walls we treated with this product have faired very well. It has made a huge difference for us. our place always felt so wet and sticky and this has helped keep the moisture out.

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 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.

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.

Works great

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.
