Protectosil® has a history of preserving and protecting valuable structures, as well as increasing the lifespan of bridges, industrial facilities, and buildings of all kinds. Therefore, the citizens of Wesel am Rhein chose Protectosil® when reconstructing the facade of their city hall.

Over the centuries, emperors, kings, and dukes have walked the steps from the market square into the city hall. Lothar Damm, chairman of Historisches Rathaus Wesel e.V., is proud of the citizens' initiative and dedication to restore the historic Wesel City Hall. The facade of the former city hall has rich tracery, stone crockets, and rosettes that extend upward into the beautiful blue sky. As the symbol of the city, the Rathaus is now once again the pride of the citizens of Wesel. Their donations funded the reconstruction project, which lasted from 2002 to 2011. One of the restoration projects included restoring some of the Flemish architecture from the Gothic period of 1400-1450. "It's truly the citizens' masterpiece," says Damm. Such a masterpiece deserves special protection, not only from the elements, but from vandalism, too. Protecting this masterpiece of Udelfangen sandstone is so important that Protectosil ANTIGRAFFITI® was chosen to provide an anti-graffiti coating. As Dr. Christine Fliedner of Evonik Industries states, "Protectosil® products are used in all kinds of buildings to extend their life and maintain their value." Protectosil® products protect all mineral-based materials, such as sandstone, natural stones, brick, concrete, clay, marble, and concrete masonry units from the elements, corrosion, graffiti, water, and pollution.
