    Hi,

    I'm about to start painting some fresh plaster which has fully dried out and some old plaster as well but there is currently no heating in the house.
    Am I ok to paint in this cold as its currently 0C in the house?

    Thanks

    personally I always let it dry out as much as possible. then mist coat and crack on from there.

    With it being so cold you'll possibly waiting a little longer for it to dry fully.

    How fresh is it?

    NOPE

    Sorry, emulsion needs about somewhere between 5 and 10 degrees C to cure properly. Granted you could open windows and find that it will become touch dry within a couple of hours but the curing process could fail as the water particles freeze.

    Waterbased paints start by evaporating, then it coalesces, the molecules compress down during this process. This takes days and will not happen properly without sufficient heat, airflow enough is not sufficient.

    I recently told the bloke working for me not to apply masonry paint on an exterior wall last week. I explained that it needs a min of 5 degrees. He ignored me and 4 days later it was still wet to the touch.
