Customers like the quality of the sealant. They say it's a miracle sealant that truly seals granite, travertine, or marble with sanded grout.

56 customers mention41 positive15 negative

Customers like the appearance of the sealant. For example, they mention it leaves a very natural look to the stone, is easy to apply, and resists scratches. Some say that it leaves their countertops with a beautiful shine, and does not change the look of the stone at all. The finish is matte, and there was no change in color or finish when it was dry and ready to use. That said, some say it adds a smooth appearance and makes natural colors come out.

Customers are mixed about the water absorption of the sealant. Some mention that it beads up on the tile and there's no sign of any water seeping into the grout. However, others say that the water didn't bead up even after two coats and was soaking into the stone.

47 customers mention26 positive21 negative

Customers are mixed about the stain resistance of the sealant. Some mention that water stains, food stains wipe right up without residue, and it keeps the surface perfectly resistant to stains. However, others say that it kept staining and looked terrible. It has a rough touch to it and water would leave marks.

"...Now I'm worry free! No filmy residue, just my beautiful, stain resistant tile.6. Finally, throw out any rags you use after the fact...." Read more

"...number of “good” sealants on our bathroom counters, yet the counters continued to stain with anything that wasn’t pure water hitting them...." Read more

"...Also, the sealant did not discolor my granite stone which I was originally worried about before I applied it...." Read more

"...There is a slight risk of white residue (dried and too thickly applied product) becoming visible on surface...." Read more

46 customers mention23 positive23 negative

Customers are mixed about the value of the sealant. Some mention it's a bit pricey, but well worth the price. Others say that it'd be better off with a cheaper sealant, as it works better long term.

"...Easy to apply with a sponge or mop and well worth the price to avoid water damage to the patio...." Read more

"...Other thoughts - It was on the pricey side but when thinking about it, one could spend thousands on nice stone countertop and have it ruined if not..." Read more

"...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...." Read more

"...This stuff is not cheap, but you get what you pay for in sealer." Read more

Great product for sealing flagstone around a pool (even a saltwater pool!)
5 Stars
Great product for sealing flagstone around a pool (even a saltwater pool!)
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.
