Hall lining paper

Hi

after a spot of advice decorating a long drop in the hall/stairs.

It’s currently covered in lining paper but there are some patches, about the size of saucers that look like large blisters.

Repairing the plaster underneath is no problem but will need to cut a hole in the lining paper. After plastering, is it possible to bring this flat with the lining paper? Or is this likely to be poor? Never tried this before.

Stripping off all the lining paper would need a professional as too high for me.
I’d also be unable to replaster it either and could cost a lot to get someone in.

So if it was stripped and re-papered, is it possible to paper up to an external corner?
To the left of the external corner I’ll need to replaster the hall as it had a radiator changed and a rewire so chases to sort. Which I can resolve, but not sure about skimming up to the external corner with lining paper on the other side.

Those blisters could be where someone has filled a hole and not sanded it back enough.

You can cut a hole , sand it back then patch with a fresh piece of lining paper and use some powder filler to lose the join

Do you know the thickness of the lining paper that's on there at present?

Thanks for the reply and help.
I don’t know what thickness unfortunately. I would say slightly thicker than recent wallpaper we’ve put up elsewhere so maybe something medium. I guess better to be thinner rather than thicker on patching, where you could apply bit more filler.

Those blisters look like plasteboard screws or nails that have popped. If you push the wall slightly above the blister does it move at all?

Use a Stanley knife to cut them out. Run the knife about 5 mm out from the edges of the blisters, you need to remove the loose edges of the paper as well as the blown plaster. If you see a screw head or nail head in the crater either try to tighten the screw or punch in the nail. Do not drive the screw/nail bellow the surface of the plasterboard. If you still see bounce then drive in two screws, one above and one under the crater. You may need to use a countersink to get the head bellow the plaster skim.

Fill with a lightweight filler such as Toupret RedLite and sand back with 100 grit paper when dry. The hole should be virtually invisible but you might need to stab the paint with a brush to replicate the existing texture left by the previous rolling.

Fill chases with bonding plaster, use a wet brush or sponge to make sure that the bonding is 0.5mm-1mm below the surface of the paper and fill with RedLite.

If, as sircerebus666 suggests, they are the result of bad filling cut back, sand flat and RedLite. I would only try to patch in lining paper if the area to be repaired was significantly bigger.

Lining paper is great stuff, if you have a decent random orbital sander connected to a dust extractor, you can sand lumps flat and feather out the edges of the paper. I assume that you don't have either though.

The blisters are solid. Given them a tap all round. There are two, one above the other about 3ft apart. the walls are block/brick with undercoat plaster/skim. No plasterboards used.
Good advice and comprehensive reply - thank you.
