Several rooms are much the same, I cant afford to get the rooms skimmed

DIY options.

Strip the lining paper, replace any sections of plasterboard that need
it, remove the machine-gunning of rawlplugs, rake out anything loose,
undercut a sharp edge in the face of the plasterboard, use a wide taping
knife to "bridge" to nearby level surface, fill (ready-mixed joint
filler is good for buying as a bulk filler and sands very fine) and sand
it down ... expect lots of dust.


I too noticed the line of wall plugs that hadn't been removed and are
sitting proud.

The bumps dips are from fixtures/fittings/shelves that have just been
removed and the "holes" not filled before putting up the lining paper.
What may be found is that in the past the walls have been painted with
the fixtures and shelves in place so no paint gets behind these objects.
When they have been removed the dips are the thickness of the paint (and
possibly a paint ridge around the removed object.

I agree the starting point is to remove the lining paper. Just fill
dips with a fine pre-mixed filler and sand down. If you don't go too mad
with the filler hand sanding using a large sanding block will minimise
the dust. Hand sanding tends to allow the dust to directly fall to the
floor where it and be easily vacuumed up.

To remove wall plugs I just screw a screw into them but just enough so
it bites hard and then I use a pair of water-pump pliers to pull the
screw straight out, still attached to the plug. The water-pump pliers
can be used to lever out the screws/plugs by using a piece of scrap wood
against the wall to form a fulcrum point, and protect the surface of the
wall. With these types of holes I would paint them with PVA/water mix
to seal the edges before filling (or inject them with the same mix using
a syringe - available cheaply on Ebay for filling ink cartidges). With
wall plug size holes you may want to fill in a two stage process. Fill
the hole to be flush with the wall surface but it may shrink back by
0.5mm as it dries so then just fill a second time.
