9.5.4 Conditions for painting and decorating
Painting and decorating shall take account of the climatic and building conditions to ensure a suitable finish.
The painting and decoration of external surfaces should not be undertaken where:
- weather conditions may adversely affect the completed work
- frost occurs, or is due to occur, before the paint has been applied or has dried
- surfaces are moist
- rain is expected before the paint dries.
When decorating internal walls:
- cold surfaces may cause problems with water-borne paints, even though the air temperature may be above freezing
- paintwork should not be adversely affected by dust
- surfaces should be free from condensation before applying paint and coatings; they should not be applied until the moisture has evaporated from the surface.
