Stone Grip - Non-Slip Tile Treatment

Miraculous! I love this stuff!

It works

We installed large scale porcelain tile around our pool with a slip rating of R11. However stepping out of the pool and walking in wet bare feet felt very slippery and dangerous. I applied Stone Grip and left it on for 18 minutes, rinsed it off, and voila, it worked. Nice and grippy. Not like concrete or cool-coat, but much improved. So far very pleased. Not sure how long it will last and I wonder if the etching does any damage to the tile surface. But so far, so good.

Zero effect

Product does not do anything. I put it down in sections and gradually increased the time in each. There is no change on the slickness of the stone.
