I used this product on my stamped concrete driveway and pool deck. It had been about 6 years since I sealed and the old sealer was worn away. The pavers had also started to lose their color, they looked dull in some areas and there was a lot of discoloration. I put down this product in a test area and I love the results. My stamped concrete patio looked new. The entire surface was darkened, almost as if it was wet. I did notice that it took 2 coats to get the nice wet look, which was fine. The outcome was well worth it. Very happy with this product.
