The citizens' masterpiece

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.

One of the largest concerns during any restoration of an historical building from the owner and architect's perspective is that the  building facade remains unchanged in appearance. Therefore, Evonik Industries prepared a test treatment of a sample of the exact surface used during restoration. They treated the sample surface with Protectosil ANTIGRAFFITI®, applied graffiti, and then used a special cleaning agent, also a part of the Protectosil® product portfolio, to remove the graffiti. The test sample was a success. The graffiti was removed without leaving any residue or traces of graffiti behind. Neither the appearance nor the function ality of the sandstone had been altered. "That completely convinced everyone," says Damm.

A facade treated with Protectosil ANTIGRAFFITI® can be cleaned up to ten times—an investment that pays off when funding is tight. "When we compare the maintenance costs for treated and untreated buildings and bridges, we find a saving of up to 70 percent over a period of ten years," observes Dr. Fliedner. Interest throughout the world is growing, and the list of showcase projects is expanding. The Louvre in Paris and the Central Library in Hong Kong, for instance, are both treated with Protectosil®, as is the Museum of Military History in Vienna, which has been specially protected with the product since 1985. Protectosil® also beautifully protects the Opera House in Sydney and the Transamerica Pyramid Center in San Francisco, and shields bridges, tunnels, and harbor installations throughout the world from the wind and elements.

The Wesel Rathaus was completely destroyed in February 1945 and rebuilt in another location in the 1960s. When the city's citizens worked to restore the facade between 2002 and 2011 at its

original site, their efforts reflected the spirit of their ancestors, who built the Rathaus in 1455 in an atmosphere of voluntary civic engagement, spreading the fame of Wesel am Rhein in the process. The donation drive for the facade of the historic Rathaus involved private individuals and regional companies alike, each of whom purchased a symbolic brick. Donors are mentioned by name on a plaque immediately next to the steps that lead to the market square.
