Cleaning and protection of facades is generally done because of the lifespan extension of the building and for aesthetic reasons. New facades are cleaned before the building is delivered; older facades because pollution, salt outgrowths, algae and moss growth are likely to have caused or will cause damage. A study by Prof. dr. Dr. Ir. P.C. Krijger has found that at known building damage cases, 40% is caused by moisture. Preventing moisture in the facade construction, for example through hydrophobing, is one of the main protection methods.
