I am tiling this en-suite, in removing the old tiles, this boxed in area in plasterboard was partly damaged and loose, so I cut the damaged area out and replaced it with 18mm ply, solid as a rock. However, it meant when rest was plastered, it sits back maybe 4mil. How best to bring it out to same level, without removing it and putting fillets behind?
Would a skim of rapidset flexible do the trick, I will be tiling ceramic tiles on Bal Green Star 330x250.
