New Plaster: how to treat and paint correctly

Anonymous user 06/03/2024 - 2.31 PM

I have recently [October] had an entire house[circa 1930's] replastered. There appears to be some debate and/or controversy as to how new plaster should be treated and painted correctly...without plastering marks appearing or indeed cracks in paint later down the line. Can some one give me a definitive on this..to mist or not to mist and rub down before primer..or just stick on a primer and 2 full coats?

Are you a tradesperson and able to answer this question?

The specification for new plaster surfaces.apply a mist coat of emulsion,followed by 2 full coats of emulsion,however if you are including painting a bathroom, we do recomend using kitchen and bathroom paint

hi i would advise you to give all the new plaster a mist coat of matt emulsion not vinyl matt as this stops the walls breathing, do not rub the walls down until the walls have been mist coated

For new plaster simply sand lightly to remove any nibs and trowel marks dust off then apply one coat matt emulsion thinned 30 percent with clean water this is called mist coating and will strike into the new plaster and stop it from absorbing too much water from subsequent coats which are only thinned by 10 percent maximum

There is no definitive I always advise to do a mist coat of 50/50 water and cheap white emulsion with a glug of pva in and allow to dry. Then two coats of a good quality paint. There are a dozen different variations on this from a hundred different tradesmen and none are wrong but never just paint straight on to plaster as it will peel in no time.

I'd recommend once the plaster is completely dry, a pole sand then a mist coat of 5 parts water to 1 part emulsion. Then put a lamp on it and look for the low, high spots and drinks. The mist coat should help. I usually fill, sand then mist again to avoid flashing then pole sand and two top coats. Crown also do an obliterating emulsion which you can put straight on and it allows the plaster to breathe. Hope this helps.
