This should only be done once the conditions improve or when the condensation problem is resolved. Resins present in knots causing light coloured paints to discolour or even flake. Resin bleed and flaking is a common problem where dark colours are used on south facing elevations. This is because dark colours absorb more heat than light colours.

Begin by laying down a dust sheet underneath the area that you will be working in, to prevent any primer or paint spillages from staining your floor. Then clean the surface you will be working on with soap and a sponge, removing any algae, mould or surface coating, and allow the area to dry. Tape up any metal hardware such as handles or doorknobs with masking tape prior to priming and painting, to prevent stains and paint splatters.Using the wrong type of roller can cause foaming of a paint film. Sponge or foam rollers should be avoided with water-based paints. Long pile rollers must be wetted out properly. Foaming happens when air gets into the wet paint film to create air bubbles. When these bubbles burst craters are left on the film surface. Sometimes these craters dry to give an even film.
