I'm a bit of a novice at tiling, so here goes with a couple of questions :-} (the tiles are large "bumpy" whites, so the first question might be moot anyway, as i'm sure they hide a multitude of sins !)
I've patched up some holes in the walls - the biggest being about 8" diameter from a Ventaxia fan (the walls are plastered, not plasterboard by the way) but they're probably not what you'd class as perfectly flat :-} - I know you can get away with a bit of uneven- ness, but how much is too much ?
Would a splash of PVA over any fresh plaster be good enough to tile onto ?
Since it might be a few months (hopefully worst case scenario) before the bathroom gets replaced, what's the score about tiling onto emulsion (just to brighten it up in the meantime) - ok, or leave as-is (bare plaster) ?
Ta :-}
