Timber, which has been exposed to the elements for more than four weeks, should be sanded back to a fresh, new surface. A grey or weathered surface makes an unsound base and will encourage peeling and flaking. Sand the surface to remove all greyed timber. Punch any nails well below the surface, spot prime and fill the nail holes with an exterior timber filler, such as Selleys Plasti-Bond. Sand smooth and apply Dulux 1 Step Acrylic Primer Sealer Undercoat to maximise paint durability.

How do I remove mould on an interior brick wall that has not been painted? We are going to paint it after that.
