Plasterboard paper surface peeling

Don't recognise this problem. Do you mean wallpaper or lining paper, or the outer layer of "card" in the plasterboard sandwich?

Don't think the plasterboard is papered over, it's the layer of paper on the plasterboard that is peeling.

The only options really are

1. glue it back, maybe while leaning something against it. Wallpaper paste softens paper well.
2. Rip it off
3. Skim plaster over it all.
4. Fit lining paper.

Sounds like you have some sort of damp problem. Condensation maybe. Interstitial condensation?

it should have been reinforced with glass tappe.

All you cam do is remove the skim and tape the joint and re skim it

I'd go for ripping off the loose flap, sandpaper to give a smooth feathered hole, fill with lightweight filler, then maybe lining paper (again ripped to feather it) prior to light sand and repaint.

If its stable underneath, yes.

I assumed it wasnt

Agreed. I'd assumed they could get back to something "solid". As I said in my original response I found it hard to understand how this condition had arisen (damp and movement being obvious possible causes).

Still not an answer, is it the card that is stuck to the plaster? our plasterboard does not have paper,just the layer of card, if this is peeling back it can not be stuck back and you must cut affected stuff out and feather and skim with finishing compound.

Carefully peel off the paper leaving a feathered edge. Paint the plaster with diluted PVA, several coats getting less dilute. Stick on lining paper (or even newspaper) with PVA (Several layers) When dry sand down, adding paper layers as necessary or filler.

usually it won't

you only get 1 go with pva. After that the pores are clogged. Slosh loads of very dilute pva on if the plaster is crumbly, but only once. No need otherwise. Skip the strong layer, it'll just make things not stick

wallpaper paste is much better

you can't sand paper, use filler.

You only glue the centre of one layer of lining paper and then you feather it by tearing the edges back towards the centre when its dry. Then you can sand it and fill it as needed.

Does nobody in this group DIY decorate any more?

Partway through decorating the hall, stairs and landing at the moment. Somewhat slowed by having to replace the hall ceiling due to a previous leak and taking the opportunity to run network and satellite cables to upstairs while I have access; put new phone and power sockets in the hall; relocate the wired buglar alarm control panel under the floor (it has remote keypads); replace the gas cupboard door; repair damaged plasterwork; bury the thermostat's wiring; tidy the radiator plumbing; replace the underlay that is breaking up (not replaced when the carpet was changed some years ago); re-fit the PVC around the front door, etc.

I've just thrown out the old underlay, in preparation for painting the woodwork on the stairs.

Doesn't leave a good surface. You can't sand paper, try it & see.

Been doing it for decades. Not any more though.
