Great product !! This sealer was easy to apply, I did a 40x80 and walkways outside I put on two coats wet on wet, I bought 20 gallons when I got done I rinsed my sprayer with soap and water, I used my little John Deere tractor and sprayer man was that easy, I am posting pictures of inside outside walk ways the picture on the walk under porch is where a rain shower had gotten on cement the water was beading up like a wax job on car!!! Not very much of a small, I would say this product is as advertised !!!
