AFM Safecoat, Penetrating WaterStop requires a porous, absorbent surface in order to work. We suggest you first test your tiles and stone for porosity. Sprinkle some water onto the surface. If the water is absorbed quickly, then your stone is porous enough to absorb the AFM Safecoat Waterseal. If the water droplets bead up on top of your stone, then this product will not work.
