Applied this a month ago on our stamped concrete patio that hadn't been sealed for a few years. I pressure washed with a cleaner a few days in advance. We were in a hot spell at the time and I applied in late afternoon as the it was cooling down. Application was quick and easy. The last product I used was not as user friendly. Had to wait a few days as the weather turned wet before I applied the second coat with the fine anti-slip additive. This product really brought the colors back to life in the patio. I think the next time I will use the coarse ant-slip additive as I think the fine doesn't work as well as I thought it would. I would recommend this product to anyone. It was easy to apply (I used a roller) and looks great and feels fine our your feet. Patio is 16 x 35 feet and I used most of the five gallons. Price was competitive and shipped quickly. Will use again.
