I recently had a ceiling come down on me even though I prepped it with PVA as I always have in the past. the only thing I could put it down to was the fact that the paper on the ceiling came down very easily and might have left the wallpaper paste on the ceiling and this started to come away when wetted up by the PVA and plaster.
More hairline cracks on newly plastered ceilings every day

I dont think he could have got the finish plaster on the ceiling if he didn't pva first. How long did the job take him and how much did he do? I suspect that there is wall paper adhesive under the skim that hasn't been removed properly and has reacted with the skim. Personally I would be stripping it all off and sugar soaping the hell out of the ceiling a few times, some spreads are just going to get the paper off, PVA and skim to get the job done. The thing is you could easily spend a day getting the paper off and sugar soaping, when the customer comes home they wonder what you have been upto all day....
The thing is it took him and a mate, three days to do 5 medium sized and 1 big ceiling.
This included stripping off paper from 3 of the ceilings and also taking off a artex like finish from the big ceiling.
The cracks are now visible on all (!) of the ceilings so it can't be down to the wallpaper paste or at least not only.
So you think that without PVA he would have not been able to put the plaster up in the first place? But why all these cracks now and the hollow sound underneath?
I will have to get this re-plastered, but what a pain ...
Thanks

One method that could be used if the majority of it is good would be to scrape off the loose bits, scrim up all the cracks and over the patches that have come down, give the whole ceiling a tight bonding coat and then plaster over.
In an ideal world the ceiling ought to be suspended and boarded with insulation installed at the same time.
