Newly plastered walls- smoothing for painting?
 

I have just had a stud wall partion built in the lounge diner to split
the room, at the same time the plasterer filled in channels I had made
for power sockets etc. Around the edge of his work the plaster is
rough. Can I lightly sand these areas prior to applying emulsion/PVA
to smooth them out?

How long should the plaster be left before I can PVA then paint it?


Many thanks

Yes, you can sand them as much as you like.

Until it's dry.

If it's just a skim on plasterboard then a few days (say 3) should be
sufficient.

Where it's thicker such as the channels it might take a little longer

To seal the new plaster. bare fresh plaster is very absorbent (it has a
lot of 'suction', painting emulsion onto it out of the tin isn't a good
idea - one it's harder to do, as you can't spread the paint so easily,
two the paint may not adhere properly and come off at a later date.

I prefer just to use diluted emulsion paint as the first coat instead.

That's what I do. Just didn't know there was another option.

The idea of Trade Emulsion is to give the plaster a coat through which
it can breathe, Some 6 months later it requires a couple of coats of
real paint.

The PVA may be an option. It is used over fresh plaster when another
coat of skim has to be put on it. I'd go with the old fashioned method.

(It's cheap and effective.)

As far as I'm concerned there isn't... I used dilute PVA for this purpose a
few months ago, rather than my usual dilute emulsion, on the advice of my
plasterer, and it was an unmitigated disaster. The PVA sealed the plaster,
sure, but the ensuing paint would not adhere to it, and you can pretty well
peel it all off with a fingernail.

DON'T!!

Not quite.
Dulux -and presumably others, do make a specific trade paint for newly
plastered walls that are not fully dry - called Supermatt.

The standard Trade Emulsion needs treating in the same way as the
'comsumer' emulsion paint, it certainly doesn't need overcoating again
'real' paint.

Previous plasterers told us to dilute PVA and apply to the plaster to
seal it. Then emulsion over the dry diluted PVA, this worked fine.

So that's how DIYSOS get away with it :-)

It needs to be dry, not just set.
