Have tried numerous " BIG BOX" store brands over the last several years and was always disgusted with the appearance after just a few weeks. I applied one gallon on 320 square feet of stamped concrete patio 30 days ago and the look is fantastic. I will be adding a 2nd coat soon. The first coat will be absorbed quickly and may not give you the coverage that you want. I would recommend a 2nd coat to make it shine. I did apply 2 coats to a set of steps and they look great, just like being wet all the time... As they say, you get what you pay for, this product is well worth the money.
