John,

We were under the same impression. The builder and the homeowner were VERY insistent that it is marble… Could there be something on it, like Tuff-Skin or something similar? We saw no sign of a topical coating, but the lack of reaction is leaving us scratching our heads…

Thank you, we appreciate your business!

If you used Muriatic acid and there was no reaction you are not dealing with a marble product. Marble is a calcium carbonite product and acids will react with all marble.

Are you sure you are not dealing with a porcelain tiles that looks like marble? If it is a porcelain tile then you probably need to diamond hone it or try some other acid based anti slip products.

Subject: Non-Slip Treatment on Manhattan Marble

Hey everyone!

We have a homeowner with a Manhattan marble shower that the floor pan is slippery. They want it to be as slip resistant as possible. We have tried invisi-tread with no result at all as well as a 50/50 mix of muriatic acid/water and it didn’t etch the surface or even show any signs of a reaction. Any ideas?

Thank you!!
