Having the bathroom tiled in the new year, it has been decreed that that the wall will have a band of mosaic tiles and that the band will probably be travertine(sp?)
I know that it should be sealed, but when?
On the basis that I am happy to do the donkey work I have no issue preparing the tiles rather than have the tiler do it, but do you? or is the sealant applied at the end? Does it matter???
