Yeah this is one of the problems on re-skimming over paint had it loads of times, we started using thistle bond it on every over skim now not had the problem since.

Some times get a little bit never a massice bit. Some times I score it, other times I use a wire brush. Pain in the arse

will bond it stableize the paint?,,
we go back to the old "your only as good as what your going onto" hoping paint is going to hold the skim is looking for problems ..
think its going to be devil all over then wba or bondit form now on :-\

pva too thin, make it thicker like carping also let it dry before you skim if you suspect there could be a problem with the paint, this tends to work, sometimes it does not.

we are not talking about the new skim not bonding to the paint..my skim bonded fine as i could see because as i took off the blown part, the paint was well bonded to the back ..it was a case of the old paint came away from the original surface

The water in the plaster soaked through the pva, then the original paint, causing it to blow. could also be that the original paint never really adhered to the original plaster.

get you now del, as it happens the part that came away was very dry and the paint came off in big sheets..not like paint that was well bedded ,if that makes any sense
