Hi. I have recently partly laid a bathroom floor using 2'x1' porcelain tiles in my home. The tiles are laid on a 3 ply substrate secured at 6" centres on a new 22mm chipboard batroom grade floor. The tiles were wet cut and laid using Ultratile ProRapid flexible tile adhesive. The day following laying I noticed staining of about 70% tiles which could not be removed using proprietary agents - Flash etc. Appeared as though the stain was under the glazed finish. Inspection of other tiles in the same batch does show staining (before laying). A simple water test on the tiles show water will cause temporary staining of the tiles before they dry out, the supplier arguing that this 'is acceptable and normal for their porcelain tiles' - I thought porcelain was impervious to water? However, on the tiles I set out, cut and laid there was no staining apparent at the point of laying them. The supplier argues that I should not have laid a clearly defective producy, but I contend the stains on the tiles I laid were not visibly stained during laying process (otherwise I would not have laid them). It is the consequential issues of the time cost of ripping up the sub floor and relaying alternative tiles that concerns me but not the tile supplier. Can anyone offer advice please.
