Not sure if this is one for this section or tiling, but I'll try here first. I have a small utility room with uneven tiled walls(not flat) that I would like to level & cover with lining paper then emulsion, as the tiles are stuck direct to plasterboard & removing them would destroy the walls. Can anyone tell me if it is ok to skim tiles with board finish or bonding & what sort of prepping is required or perhaps suggest an alternative solution. Dot & dabbing is not feasible due to all the things fitted to the walls. Thanks.
