Son's bathroom (top floor of block of units with roof space above) has plaster ceiling that has had a dividing wall made much less "jutting out" so there is now a hole in the plaster about 300mm x 600mm. Hubby took a look today. Patching with a piece of plaster will be easy, as will re-cutting the cornice to fit the new smaller bit where the pipes have been condensed into a smaller jutting out section.
Problem is that the ceiling has a speckle paint (?) finish. I'm fairly sure it is simply a paint finish and not vermiculite.
I've looked around a renovation (plaster) forum but cannot post there even though I joined a while ago (not sure why).
Two options -
1. Patch the hole, tape up the join and skim it, and then try to match the textured paint (probably will look bad).
2. Sand back the paint, or try to scrape it off and then sand it, and then skim the whole ceiling.
Best option would be a flat ceiling and the room is small, so it would not take long, but I'm wondering if the skim coat would stick to the speckle paint if it doesn't sand easily.
Some suggestions on the other forum seem to say to skim with cornice cement. Anybody done this?
Any tips?
If it all turns to custard, it would not cost much to knock out the old ceiling and bung up new plaster, in which case we could use bathroom grade plaster, but this has worn well for 50 years with no exhaust fan, so I don't think we need to do this. Ceiling fan will be installed with this work.
