    Mine is to use a high quality eggshell paint.
    A couple of coats covers and copes with most stains/bleeding and can cope in a hostile environment like swimming pools, showers etc"

    "Use Zinsser shellac. Apply with a medium pile roller. Ensure the finish is smooth.
    Don't hang about, this will start to dry within minutes, especially if the room is warm. Keep the area well ventialted.
    Stir the tin thoroughly and stir every few minutes of use."
