We applied the Armor SX5000 with a roller, it was very easy to apply and it soaked right in. There is a strong chemical smell so make sure you are ventilated and don't breath in the fumes when bending over the pan. I would say it was dry in about 1 hours. After it was dry the driveway was a uniform color, the same as when we started, not patchy colors as some people mentioned. The 5 gallon can barely covered our whole double wide driveway that is about 35 feet long. So our coverage was a little less, around the 125 ft^2/gallon as mentioned on the literature. We were extremely happy on how well packaged the 5 gallon can came and it was delivered on the date as promised. We have a large rain storm coming tomorrow and snow will be here soon, waiting to see how it all works.
