Review on Miracle Sealants PLUS QT 511 Porous Plus Sealer 32 Oz Quart by Brent Shaeffer

We have struggled to find a good sealant for the flagstone coping around our saltwater pool. Products we have tried have not been effective for very long and/or made the stone shiny and very slippery, dangerously so. The stone was chipping and flaking very badly and we were getting lots of sand in the pool. Miracle 511 Porous Plus has sealed the stone and not made it slippery, and it did not change the look of the flagstone at all. The amount of sand in our pool after a long day of kids' swimming has been reduced to near nothing. Water beads up on the stone rather than soaking in (see the photo in this review) but surface is not slippery. No more chipping and flaking.Product is kinda pricey per quart. I needed 3 quarts to put 2 coats on my 110 linear feet X 12 inch surface. One coat might have been enough but I wanted to solve the problem once and for all. The 3 quarts also covered the water-facing edge and the small underside surface of stone, both of which get a lot of water splash. But the cost has been well worth it. I used a 5 inch brush for the main surface and 2 inch brush for edge and underside. I also applied it with water in the pool, just drained the water level down a bit. 2 coats took about 8 hours over 2 days but you can apply a second coat an hour after the first so it can be done in one day. Will have to see if I need to put another coat on next spring or not. I don't think I will, but if I do, it will still be worth it and I will probably need only one coat. This has been by far the best product for a tough problem.
