i know its horrible to do but have you seen it since and seen where it may have gone wrong?
ive had similer problems in the past with painted surfaces bubbling....... but i reckon the existing plaster was either painted with silk straight out of the tin or the ceiling was once papered then striped and painted. the paste residue could have reacted and made the plaster bubble. but dont quote me on that ;D

i'd be looking at where the plasters lifted ........it could be the paint/old artex (plus paint) etc and take it from there ..........it sounds like a s**t mate a usual job gone wrong ......but if i would redo it i'd either over/reboard the ceiling or scrape the defective stuff off the wall and gypbond/wba the ceiling
cant remember the last time i pvaed and skimmed a ceiling i always advise overboard reduces the chance of cracking, more sound barrier and extra fire protection. That ceiling your on about would of been 15 pounds in materials to over board and you wouldnt have this problem. Tell him to keep some of the skim thats fell off it will have the paint on the other side its the paint thats loose or could of had paper, ive nearly come unstuck in the past with paper thats had 3 or 4 coats of paint and you couldnt tell. 15 pounds of material to overboard, its quicker than waitin for pva to dry and the cost of the pva and the chance of it goin pearshaped and believe me when you tell a customer they will get an extra hour before the fire travels they usually say yes

The risk you run when overskiming emulsions etc ,i always tell the client that the plaster is only as good as the background it's applied to, Flinny's right it is just as quick to over board and the costs of the board are relativley cheap, but then you have to consider labour and i'd be damned if i am gonna board it and skim it for pretty much the same price, so in short you have tried the cheaper alternative and it has not worked so you need to explain to the client you tried to help him out by doing an overskim but you cannnot be held responsible for the substructure and any other materials applied to it, hopefully the client will see it your way , and you should be able to reach a mutualy beneficial remedy. You have had and will no doubt receive a lot more advise , but you no your client and should be able to make a decision on which way to approach and address your small problem.
As they say " s**t happens" so wouldn't lose sleep over it, and just try to be more diligant in your approach, (hope that does not sound too condecending, was not meant to be).
Good Luck

well...
my bread and butter is overskimming artex ceilings..
9 out of 10 is one or two coats of pva, thick first one, top as normal, nip it up into the coving line, comes up nigh on perfect, and by that i mean good as board...
if it is overboard, and it is coved, the coving comes off and gets redone..
if i want the job, ill price accordingly, coving cost about 20 quid a room, takes under an hour and can be put up soon as the ceilings gone dark.. in other words, an extra HOUR and an extra 20 quid...
blending the ceiling into the cove looks pants..
i only overboard if it needs it though, and these days that isnt that often..
