Painting newly plastered walls

MascaraMinx

Quick question - can I paint with emulsion directly onto the plaster or do I have to put some kind of protective coating down first. We've just had our hall and stairs replastered and I'm dying to get it painted, but have a sneaky feeling I should do something else first!

You can paint directly onto the new plaster... you will probably have to put an extra coat on as the first coat will soak in a little

My plasterer advised me to wait a couple of weeks (for a skim - a month for full plastering) and then make the first coat diluted, by adding 50% water to the emulsion. Had no problems after a couple of years.

Hi we always PVA the walls first... just had a bungalow built into a house and did this on every wall and ceiling and weve had no problems at all (touch wood):rotfl:

Please read this thread before you do anything, specially posts from handyman.

I use diluted PVA in one of those pump up fence sprayer things. Only takes 5 minutes but remember to clean the sprayer out afterwards!

Watered down emulsion paint will work just as well.

What you are attempting to do is seal up the pores in the plaster and also stick any remaining plaster dust to the surface of the wall.

The danger with using PVA is that if you put on too heavy a coat you'll have problems getting paint to stick to it. I use 50/50 water and cheapo emulsion, works a treat.

Incidentally, this coat is termed a "!!!! coat". Wonder if that'll get past the swearie-warie filter?

you dont use pva, read link misgrace pasted on this thread.

I think i'll start recommending doing your own gas work, as this site appears to allow info to be posted thats incorrect........lets start causing explosions

handyman.

the first coat of paint on new plaster is called a mist coat. You follow instructions on tub (of dulux trade supermatt, get it in bnq) which state to water down first coat by 20%, then paint as normal.

Nowhere on the tub does it say anything about PVA, and for that matter, nowhere on any tub of paint (for walls) does it say anything about pva.

It is wrong, so dont do it

You might call it a *mist* coat

Incidentally, there's nothing wrong with doing your own gas work, not for reward, as long as you're competent. Corgi would have us believe otherwise, of course.
