    Applying anti mould pain onto plaster

    Painters & Decorators

    I have a patch of mould in a bedroom. I’ve had it checked by a damp specialist who says it’s to do with the temperature of the external wall not penetrating water or other causes of damp. I’ve treated it with mould killer but can I apply anti mould paint directly onto the plaster or do I need to do something else first?

    "Good afternoon,

    I would use Zinsser self priming paint satin. It's a very good mould killer and stain block it guarantees to kill mould for 5 years.
    It's £15 for 1L but worth having.

    Then you can crack on with your white wash and paint!"

    "Yes you can apply anti mould paint directly onto plaster, but try and give the plaster a wipe down with bleach first."

    "You will find this happens when hot air and the cold air from outside meet it causes black mould. Get a good air flow in the room, stain block and repaint"

    "Yes you can put anti mould paint straight on to plaster because it can act as a primer or undercoat"
