Looking for help. I have about 8 holes like the images and had various
recommendations. This is what looks like plaster or browning straight onto
breezeblocks. No plasterboards.
Some say, use pva and the pollyfilla then sand and PVA again. Others say just
Not sure what to use for the best.
PVA inside of the hole or the water will be quickly sucked out of the
plaster or filler you use to fill the hole and it will crack up. Use a
50:50 mix of PVA and water and paint the whole inside of the holes. Let
it dry and just before applying the pollyfiller just give it a quick
coat of PVA/Water again.
You may want to apply two coats of filler, the first one to just below
the finished surface and a second thin coat level with the finished
surface. This will help minimise any sanding. You could use a finishing
plaster as the "filler"

Ditto the use of PVA, but I would use Wickes one-coat filler
as a base coat then Wickes fine-surface filler on top.
why is the surrounding wall stippled ?.
Is this a textured coating or painted woodchip ?.
Either way you need to remove it (woodchip) or
having the entire wall skimmed professionally if it
is a textured coating.
matching that stippled finish will not be easy
(though my grandmother did some fantastic pottery
dinosaurs when we kids and used Grandpas aertex underpants
to make the stippled appearance.
One last point, is this Cornwall in a property made of
Mundic block ?. You need to keep this dry or it will
Go with the PVA, seal with a very dilute mix and just before applying the p
laster apply a second adhesive coat approx. 50:50. I would then fill with b
onding coat 11mm at a time. Strike off any excess with a straight edge or D
erby filling any depressions. Scarify the finished surface once set and app
ly finish whilst base coat has plenty of moisture. If you have to apply fin
ish at a later date then seal the base coat surface again with dilute PVA.
One of those holes looks like the plaster on one edge is coming away from t
he wall, you need to enlarge the hole until you reach sound plaster. Using
a hammer and chisel may cause more plaster to loosen and you end up replast
ering more than you wish. A gentler way of removing the plaster is to tap i
t to establish where it is sound and use a carbide blade in a multitool to
cut an edge then use a decent scraper to prise away the plaster to your gro
