I did a lot of research on cleaning and sealing my decorative concrete driveway and paver pool deck. I had previously sealed both and was disappointed. I expected them to shine like when it rains. It also did not last long and I noticed quite a bit of fading. I had a friend who used Mold Munchers and was impressed with how their deck turned out. I was not disappointed and want to thank Steve and his team for an excellent job.
