There are many types of pollution that can affect the facade. This includes black and green deposits. For example, green deposits can form when a surface remains moist for a long time. Deposits on the facade give an unkempt and neglected appearance, but also affect the substrate.
Protection of the surface
In addition to cleaning the facade, maintenance is also very important. For example, you can choose to impregnate the facade or treat it with, for example, a renovation coating. Choice of method depends on which properties are desired. Both the impregnation of the facade and the application of a renovation coating provide dirt-repellent properties such as atmospheric pollution. By impregnating the facade, you ensure that no more water is absorbed or allowed to pass through the facade. The service life of the application is also a choice-determining factor.
