Where damp is a problem it may be due to a defective or missing DPC, broken or defective rainwater pipes and gutters, defective pointing in brickwork, unsuitable cladding, solid wall construction or other general building defects. The source of the dampness should be found and cured. The surface must be allowed to completely dry before painting. A shellac based sealer can then be applied prior to overpainting in the finish required.
