I am finding light blotches on my bathroom wall tiles, they are ceramic from British Ceramic Tile.
I fitted the tiles to the walls of my bathroom three months ago with Dunlop RX 2000, I used a notched trowel and back buttered every tile with a coverage of 100%. Grout is Dunlop as well.
I would say the shower has been used around a dozen times since the tiles were fitted, marks are in the shower and other parts of the bathroom which don't get that wet. There seems to be no particular pattern or location on the tile, some tiles are affected and others are not. The tiles have only been cleaned with water and a wet sponge since being fitted, no cleaner whatsoever.
Can anyone offer an idea what this is? Thanks in advance.
