For building cleaning and paint removal we use the Doff system which is a specialist cleaning method. This system uses a normal water supply which is taken into the pressure pump unit. Here the pressure can be increased to the required level before entering the hotbox. The pressure settings are independent from the temperature settings. If necessary, the temperature can be increased to 150°C. before it passes through a heat resistant nozzle, which is used to direct the super-heated water onto the surface to be cleaned. Buildings are covered in dust, grime, graffiti, moss and algae as a result of pollution, neglect or weather. As well as producing an unpleasant impact for a home or work environment, the structure of the building is also affected. We are well aware of the impact chemicals have on the environment and we always choose the best method in cleaning a surface, having in mind the protection of the building and the client's requirements. Sealants and protective coatings can be applied to protect the area from daily pollutants. Surfaces with a high risk of graffiti attacks will be sprayed with anti graffiti coatings. Applications:
