painting plaster?

[OutOutLetItAllOut]

hey, can you paint straight onto a newly plasterd wall? it was dont about 6-8 weeks ago
any ideas?
thanks!!

No, you need to seal it with a Mist Coat of diluted white matt emulsion, although i can't remember the percentages now. otherwise, the new plaster sucks the moisture out of the paint and the paint peels off.

SoupDragon's right.

I think our painter did a half and half solution.

i thought that, i have heard, i think, that you can do a 4 -2- 1 solution of pva...any idea?

you can do a pva solution i use that on all my walls to seal them. no problems and been doing this many years!

Half and half water and matt emulsion.Just had ours plastered top to bottom and dp and I plan to do the sealing and plasterer says not to use pva but that may be our house But emulsion diluted is what we have always done and it is good

if you have a period property that needs to breath dont use pva use the above.

Our plasterer advised against PVA, we just used a mist coat as described above -- watered down emulsion. Our plasterer said the consistency should be 'like milk'.

PS Did not mean to imply that PVA was necessarily not right for you -- our house is 1930s and the plaster was a skim on top of the old stuff, so the advice against PVA may have been specific to that situation.

Heartsease-i do hope your plasterer has not skimmed with gypsum plaster over all lime plaster.Gypsum (brown) plaster stops the walls breathing.Moisture collects behind it and it falls off as well as causing damage to your walls.If you have lime plaster it should have been knocked back to brick or else hydrated lime (white)plaster should have been used

You can buy trade paint which is especially formulated for new plaster.

Brassband I don't know the details but he was brilliant and highly experienced and he identified various issues which needed special treatment. He came with glowing plaudits from our friends who both restored and extended their much older house. All the tradesmen who have worked there since have admired the plstering. So I'm not worried, thanks.
