Hello,
I've just had a room skimmed. Before the plasterer left, he told me I could get rid of any blemishes by gently sanding down before I painted.
This seemed to make sense, so that's what I did. What I did not do, was wipe the walls down after with a damp cloth to get rid of the dust that seems to cling to the walls.
So I started to paint with watered down emulsion on a roller (Crown Matt), and the first coat went on ok. When I went over the paint again with a second coat, the paint started to peel off in places.
After asking around, I have been told that this is because the walls were dusty - my mistake.
I've searched this forum for a remedy, and the advice seems to be to dampen the walls down with a sponge and scrape the emulsion off my hand.
I've tried this and while it does work, it's going to take me weeks. Every square inch has to be fought over to get the paint off. I've got 30 Sq Meters to do (screwed up on a large scale here..).
So I started asking decorators what they would do and the response is varied.
One decorator told me to SIZE the wall and then re-paint it. I've bought some packets of SIZING but it seems to be wallpaper paste?
The next decorator told me SIZING was wrong, and that I should PVA the wall prior to a new coat of emulsion.
I went back to my plasterer to ask his advice, and he told be to gently sand the wall down and repaint it. I've done that but the paint still comes off on the roller. It doesn’t seem to budge when I use sand paper.
Either I'm being told pork pies or they’re all correct.
Yours,
Confused.
EDIT:
Just spoken to Polycell who told me their Wall Size product would be of no help whatsoever. That decorator who put me onto this, and the bloke in B&Q who sold it to me were very convincing though!
The chnical help line at Polycell told me to use hydrostrip 1003.
