So I have stripped this kitchen wall back and the skim coat has come off most of the wall with the tiles. Underneath is a bonding /base coat plaster. That is sound and level. But for the lack of a skim coat the wall is in great condition. I know that you can't tile on bonding and I would normal reboard but there isn't the depth at the back of the hob to do so. What plaster do you use that can i skim on that is suitable for use on an undercoat and will set off sharpish?
