Hi all, renovating a wall that has been stripped of paint back down to plaster. During the stripping, some areas have been damage and I am planning to skim coat the wall to fix them. My question however is, can I skim coat bare white set plaster? I ask this because I have been told it's best to seal the gyprock but I don't want to have to Seal the white set plaster, do the skim coat and then have to seal the skim coat too., seems like a lot of sealer wastage. So it was recommended that the skim coat be done first, over the plaster and then seal the whole lot together. Does this sound like the right way to go about it?
