I am refurbing my sisters bathroom (old stone terrace). When the old tiles
were removed a sizeable patch, 2ft x 2ft, of plaster has come away down to
the bricks approx 1" deep. My plastering skills leave a great deal to be
desired! I realise that my plaster surface doesnt have to be perfect for
tiling onto but for other reasons I think it would be better and easier
dotted and dabbed. What do I use to stick the PB to the brick? Can it be
bought in small (readymixed) quantities as I will not need a lot?
I could not recommend filling in a gap in ordinary plaster with dot-n-
You could square off the old hole and find even more plaster came off.
Or try to cut a
funny shaped piece of PB to fit.
I would pour/paint/inject watered-down PVA behind the edges of the old
plaster to ensure
it is well fixed, then PVA the bricks and old plaster, then fill using
bonding plaster. Use the old plaster
around to guide a straight edge over the new plaster to level off. It
does not need to be smooth.
Its actually quite easy. You apply the plaster by pushing up and
against to wall to
make it "stick". You could do it in 2 layers of half-inch each, score
and PVA between layers.
If you want plaster board, use stuff called dry-wall adhesive (bags
are cheap), or some bonding plaster with a bit of PVA mixed in. Or
even car body filler, no-more-nails at a stretch.
Yes, as Simon says it is quite easy especially if the wall will be tiled
Use well watered down pva to thoroughly seal the surface and run it into
any edges etc.. Use, say, 1 part pva to 4 parts water depending on the
porosity of the wall.
Then just before plastering, paint the whole area again with slightly
watered down pva, say 3 parts pva to 1 part water as a bonding. Apply
the plaster before the pva dries.
If you want to dot and dab and put plasterboard up, then Pinkgrip or
similar can be used for a small area but would probably be uneconomic
for a larger area compared to the bags of powder.
Bonding plaster,no need to use plasterboard.
Just start slapping it into the hole till it becomes proud of the hole,then
get a piece of wood wider than the hole and draw it over the hole to bring
the bonding level with the existing plaster.
