    I just had my house plastered. It's a brand new house so no heating in it to help the plaster dry. How long should I wait before painting it?

    Not trying to be smart, but when it's dry! When the plaster's gone white and is bone dry, then paint.

    Hiya,
    The longer you can wait to paint the better ..
    We renovated our house two years ago and just a heads up w.r.t painting plaster , we dry lined and re- plastered all the internal walls of our house and now after two years we are seeing spots appear everywhere on the plaster throughout the house .It is know as ghosting ! Now we have a legal issue on our hands with our builder as we are going to have to fix this and repaint the entire house . Make sure that you seal your walls . Some painters will tell you not to , but trust me it is worth it but get advice from a good painter . In our case when the walls were dry lined , where they used nails to attached panels to the walls they did not plastic cap them . Now what's happening is the damp/condensation is coming through these nails to form spots on the walls. We will either have to strip back the plaster and plastic cap each hole or we could put PVA over the areas , the put another sealants on top and then repaint ...
    Hopefully your builder did everything correctly so you wont have this problem ..

    Thanks for that. I think I will get the painter to hold off for a couple of weeks. He is using a sealer so hopefully that will help. The last thing I want is for the paint to peel or even worse have to replace or repair plasterwork.

    Just another question. I am getting a family member to paint it and trying to work out a price for his work. The house is a 4 bed over 3 levels (dormer)with 2 en suites, a main bathroom and a toilet downstairs. Downstairs has a kitchen, dining room and a sitting room and hallway. Think it is around 1800sq ft in total. Would anyone have any idea of what a rough price would be to paint it? I'm going for white ceilings and magnolia walls with white doors and skirting and I'll be supplying all paint.

    As said earlier, when plaster is fully dried, make sure house is ventilated or it will never dry sufficiently. Also wait until it is a little warmer. Surfaces should idealy be above 7 degrees for most paints.

    Thanks for that. I've decided to hold off till Easter for the painting as I'm hoping to get the heating on by then which should help to dry everything out.

    In the meantime make sure that you have a few air vents open, or if its an air tight house, crack open a few windows 24/7. Heating isn't essential imo as long as its warm enough for paint to stick. Concrete continues to cure/give off moisture for about 2 years after it sets. If your windows are streaming with condensation, you need more ventilation.

    Thanks. The house is airtight and as its over three levels would it be enough to leave a couple of upstairs windows open as I wouldn't feel comfortable leaving downstairs windows open? With regards to concrete I bought the house unfinished and the blockwork was done 7 or 8 years ago..or does the same apply to plaster?
