TLDR: What do I fill these larger holes with before skimming, and do I use bonding, undercoat plaster, hardwall, or just skim with multifinish?
Currently doing our bathroom. All the walls except one are plasterboard, so they're about to get boarded, but the last wall is render/plaster over brick:
The bit that's currently got the old pinky paint on it is going to be the 'show' bit, everything below the bottom edge of the window will be tiled so it just needs to be flat. I've hacked out all the loose, so everything that's still there is solid. There's a pretty big hold below the window - bit unsure what to fill this with. Just a bit of sand and cement? I'm probably going to sand and cement the top jaggedy part in where I've replaced the ceiling too.
I've skimmed a wall that's similar to the top half of this one, and I just got all the loose off, PVAd and skimmed it, came out fine - but this is quite a bit rougher and is really mixed surfaces.
Do I use bonding for this, or undercoat, or hardwall? I can't really work out what's appropriate, they seem similar. Can anyone fill me in (no pun intended)
The bathroom is extremely tiny so I don't want to batten and plasterboard, or dot/dab and plasterboard, I don't think. It's about 1200mm from the door to the wall! Every mm counts.
Thanks
