Generally speaking neither glazed ceramic nor porcelain tile needs to be sealed on our shower wall. The grout, however, does need to be sealed assuming a standard grout. We offer AFM Grout Seal for this purpose. Use 2-3 coats. The grout sealer will not hurt if it gets on the surface of the tile, but it might change the appearance slightly and will eventually wear off.If however, your tile is natural stone you could use our AFM Mexeseal. Please, please, please, test first to make sure it adheres properly before purchasing. In some cases the stone is too dense for water-based sealers to penetrate and it will just sit on the surface and not seal properly. We have not found any non-toxic sealer for polished marble, granite, soapstone or other dense natural stone. While they do exist, most do not perform well enough for us to justify selling them. If you find something that is truly non-toxic with no solvents that performs very well, please let us know.
