I put the product on according to the directions in the evening before the sunset. The concrete pad I rolled on like you would roll on paint on a wall. Extremely easy to put on there were no complications. As far as the wall it was extremely rough and had to be sprayed on. The liquid is a little bit thicker than water and you need a tremendous amount of pressure to force out the liquid. I was told that The product may not come out evenly. I was able to move the wand around to get the sealer spread out evenly. For cleanup I use just dish soap and water. Love the product
