Monument protected building in Berlin

This monument base was polluted for a long time with graffiti. Basically you could say: the longer graffiti stays on a surface the more difficult it is to remove it. Especially on the south side graffiti tends to burn into the object.

When this happens it is nearly impossible to remove the paint without any remainings. While cleaning this monument the very fine blasting medium Jetglass SG 150 has been used. The surface of the natural stone has not been harmed during the cleanup.

The very busy street "Heerstrasse" with many pedestrians, was not a problem during the cleaning of listed monuments. Without blocking street and sidewalk the jobs could be done quick and easily.

Other blasting methods such as sandblasting or dry-ice blasting would only be used with great effort, extensive barriers and substantial folow-up work. The cost of the graffiti removal and the risk of damage are much higher than using the cleaning equipment Tornado ACS.
