I used this to coat the inside of a large Tig welder recirculating cooling tank. As other users suggested I had an additional paint brush on hand and I also trimmed its bristles so they were only 1.5 inches long as this stuff is thick. Using it along with this product worked like a champ! I will be using this for many other projects in the future that do not require it to be wear resistant but need to be very water repellant. Great product!

I used a base coat of transparent waterproof sealant first and gave it 3 days to dry. ( my project was a second floor small porch with an old rubberized floor that had been cracking) I wanted to seal it to keep water out and prevent it destroying the first floor porch ceiling. Then I used this rubberized paint. Loved it because it is colored a light gray and it is self leveling. Not bad work for an old lady if I do say so myself.

I used this to seal an outdoor fountain. I coated the entire bowl of the fountain. It easily covered cracks using the supplied patch cloth. It adhered well to old concrete and did a great job of sealing the old fountain. The color was a battleship grey.

This stuff is awesome. Goes on like thick paint and turns into a durable waterproof membrane. I'd wait for you to open it until you have everything ready to seal at once. I used it over 3 days and it was fine as long as you make sure its air tight. It was starting to thicken after 24 hrs in the container on the top, but it was still good to use.

First of all, the smaller sized bucket is much smaller than it appears in the picture. Still, it was adequate to my needs. I had some water damage under the kitchen sink that I wanted to cover and prevent future issues. Also, the area just gets scraped up over time. I used this to make a water proof base to the cabinet. I taped up the edges first. The first coat took for ever, and I used the brush. It went on unevenly and took a long time to apply. I then made a second coat by dumping it out, and using the smoothing spatula tool that was included and it went on very thick, and was much more even. This stuff is THICK. It is very hard to not get lines in it if that is what you are trying to do. Perhaps my application was not the best case use for it. But in the end, it worked. The other downside of this stuff is that it is very very rubbery. It's staticky, and everything clings to it when it is dry. It grabbed on to the trash can and the cleaning supplies I put under there and held on for dear life, so I needed another layer. I ended up getting a non-adhesive drawer liner to lay on top of it. That worked great to make the space more user friendly, plus it is also another cleanable layer that provides more protection against spills and damage. I don't know how this will hold up over time with pulling the trash can in and out over time, but if there's an issue I will revise this review. I also wish the color was a lighter and less bluish gray. It is also very strong smelling to use indoors. I had to ventilate well and used a mask.

OK first, I didn't use it. It may be a good product, the package is solid and instruction is clear. the only issue is, with two coats it only covers less than 11 sq ft and I think buyers should be aware of this. otherwise, it's a very good rubberized waterproof paint. I went with Drylok instead.
