I purchased this product after a neighbor recommended it to me - he had recently sealed his (paver) driveway with great results and I was interested in the same. After powerwashing and allowing the surface to dry for 24+ hours, I applied my first application with a roller and could instantly notice the nice sheen that I was looking for. After another 24+ hour drying period, I applied a second coat to finish the project, using in total just under the 5 gals. purchased. Very pleased with this product!
