I'm worried. I've recently heard that you shouldn't PVA plastered walls
when planning to tile. Fair enough, I wont add PVA to our newly
plastered walls. However, before the plastering, I did add PVA to the
one plasterboard wall, which our plasterer has now skim-plastered over.
I need to tile on this wall, and am now worried that his plaster may
fall off the plasterboard...resulting in tiles coming down! Any ideas?

Yes - stop worrying, it'll be fine.
