I have a hole in a plasterboard wall about the size of a 20p piece. Its
fairly neat - originally drilled for passing cable through. It's no
longer needed - so ho wdo I fill it and cover it over ??
Can I cover some newspaper in polyfilla and pack it, then use more over
the top and repaint ?? Any other suggestions??
A piece of ply (or similar), wider than the hole, with dabs of no more
nails on each end, slotted through the hole, pulled tight to the back of
the plasterboard and left to dry should do it.
To pull it tight, knock a small nail into the center of the ply and pull
the head of the nail towards you with your fingers - or maybe tie some
string round the head of the nail and pull tight (you may be able to tie
the other end off around a fixed point opposite the hole to keep it
tight for a while).
If you can make sure that the nail head does not jut out in front of the
wall you can just plaster over it, otherwise you can probably just pull
it out after plastering and smooth over the remaining nail hole.
this sounds like a plan - thanks for the suggestion. Do you think filling
back up to the ply will be ok with Polyfilla ?? I have plenty lying about
afetr a decorating spree and dont really want to have to start mixing up
plaster, waiting for it to dry, sealing it before painting etc etc.
That indeed is the standard method for filling bigger holes but for a 20p
sized hole ??
Probably get away with stiff Polyfilla for initial fill but I'd use filler
foam, but then I use it everywhere :-)
Paint the area around the hole with PVA glue and water mixture (1:1 mix),
let it go tacky for a couple of hours, then fill it with stiff mix of
polyfiller or plaster. Make sure the filler is stiff enough to just be able
to work with it. Smear it around the edges of the hole first to let it get
a grip, then fill it fully and smooth it off.
Just Polyfilla would be fine. Do it in two passes and then sand. Make it
fairly thick on the first pass, and slightly below the finished surface.
Second pass should be wetter and up to the surface. If it is in a concealed
location, just do it in one pass.
