tiling a friends bathroom tomorrow. using the cheapest adh. he wants to put his house on the market and move asap and just wants it sprucing up a bit. i have bought mapei d1 adh. one of the walls is a bit poo so he is leaving the tiles on. they are smallish ceramic. he has bought smallish ceramic tilesat a guess 10 by 6 ". will it be ok to use this adh to tile on tile. also the other 3 walls have quite a few bits where the plaster has come off. would it be ok to fill the holes with rapid set. a few are a bit deep apparently. i will prime the holes first with apd or bond. which is best? just going for a rubi murray and will check on your advise later. cheers folks and thanks in advance ian
