I was hesitant based on the price of this, but after applying it, it looks amazing! My 5-year-old stamped concrete backyard looks so good now! It was a very dull gray/brown color and is now extremely dark brown, I love it! I have 1,000 sq ft of concrete and used exactly 5 gallons of this sealant using a sprayer I bought from a big box store that begins with a W. I did not roll it at all and it is absolutely beautiful! I finished applying it at 2 pm when it was 79 degrees outside and then re-applied at 7 pm. The second coat was much thinner than the first but I just needed to get a few of the cracks and things I missed on the first pass. I wish I could post pictures on here to help you see the evidence, but if you want to share your email address, I'll send you the before and after pictures.
