    Can I paint on new plaster?

    Painters & Decorators

    When painting on freshly layered plaster, how would be the best way for me to paint over the plaster without causing a mess or any problems to the paint/plaster later?
    The plaster is dry, but it has only been a few days since it has been completed.
    I’ve been advised that I could apply mist coats first to help seal the plaster – is this necessary, or should I just wait a little longer for the plaster to settle before painting?

    "The best thing to do before painting new plaster is to give it a coat of emulsion which has been thinned with 50% water. An alternative is to use a bare plaster sealer before finishing with 2 full coats of emulsion."

    "Once the plaster has completely dried give it a light sand and then apply a mist coat (diluted Matt emulsion paint) to the walls. Once this is has dried, apply 2 coats of the paint of your choice. Alternatively you could seal the plaster with a coat of diluted PVA solution followed by the finishing paint."

    "Hi,

    As long as the plaster is dry (no dark patches where it's still wet) then it's ready to paint. Yes, you must apply a mist coat to it first so it adheres to the wall. To apply a mist coat add around 20% water to some paint (it doesn't have to be expensive paint, anything will do, preferably white. Once misted, apply 2 top coats of decent paint."

    "Hi, you definitely need to give it a mist coat, The watered down paint (50/50) with water absorbs into the plaster making sure you have a much better finish if not it can be patchy and won't cover properly at all and more importantly the paint can peel off if the plaster has been finished to a mirror finish. So yes, always apply a mist coat."

    "Yes, you can, all decorators will give you different advice on this."
