I have a ceiling that originally had a wallpaper covering over the

over it if I PVA it well? Or will it need to be reboarded?

From experience. I'd be inclined to get a quote to overboard and skim.
Then work out if the effort and likely result in patching the existing
would be worth it. And then factor in if any further cracks might appear.

Or, rip the existing down and board/skim. But factor in some grotesque
mess, especially if it's an older home.

IIRC it was about £300 to overboard/skim a 5m x 4m room and takes a day.
They've worked really well in my house, and the plasterer somehow got it
to merge into ornate coving. Small gains in sound and thermal insulation
too.
