TWO skim coats AND a TOP coat??
How thick
is the paint on the ceiling?
IMHO this is a lot of work and effort for a NOVICE. The additional cost for purchasing the materials, though not too expensive, is more than what is required.
I have done this type or repair and there is really
only one way to do it properly and that is to strip the ceiling back to the plasterboard. This too is a lot of effort, but it is the
ONLY way to know that the "base" from which to work, ie to repaint, is
COMPLETELY sound.
Even IF it was feasible to place three "skim" coats of "plaster" within the thickness of a coat of paint, there would still be doubts about the remaining surface. The remaining surface *may* last but for how long??
Gooner, if you do not want to strip back the remaining ceiling, then I recommend you feather the edges of the remaining paint and SEAL the ceiling with an OIL BASED sealer paying particular attention to the feathered edges.
You could also consider painting the "exposed" parts of ceiling (only) with several coats of sealer to build up the level of paint to that of the remaining "sound" paint. (This is easier to do with a paint roller than to plaster with a trowel). Then seal the whole ceiling with the OIL BASED sealer.
Acrylic sealers are very good but an oil based sealer is even better and they don't smell as pungent as they used to
Be aware though that if you don't remove the existing "sound" paint, you may need to do the job again. Stripping the paint is not too hard if you
carefully use a quality paint stripper, obviously trying not to damage the paper surface of the plasterboard.
Paint the ceiling with a low sheen finish. This will help minimise any moisture being absorbed into the ceiling paint and it will help hide the ceiling "blemishes" better than a semi-gloss. The light fitting you currently have as per the photo (providing it DOES have a shade) will also help "disguise" any minor errors in the feathered edges or paintwork.
If you do not have a ceiling fan in the bathroom I recommend you have one fitted. This will help dramatically with the prevention of moisture absorption in the ceiling painwork.
Good luck with whatever method you choose
