    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."

    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."

    "You could just dilute the paint with some water for the first coat just to help the top coats finish smoothly. As long as the plaster hasn't got dark patches it'll be fine."

    "Good day,

    Regarding your question, it is best to give yourself a primer before painting the wall, this adds protection on the wall and paint."

    "Yes absolutely, apply a mist coat first. I personally always do 2 mist coats.
    If the plaster has changed from dark to light all over then it's good to go but if you aren't 100% sure then leaving it another day or 2 is advisable."

    "Wait for the plaster to dry properly then white wash the walls before you apply your main 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."

    "It needs a mist coat because the paint will soak in. Around a 50/50 mix will be fine."

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

    "First coat on fresh plaster should be watered down emulsion."

    "Would definitely follow what you've been told regarding the mist coat."

    "No, you would have to apply a mist coat no matter how long you leave the plaster to dry. It needs to be sealed to stop sucking all the moisture out of the paint too quickly."
