Since its initial opening more than 120 years ago, the Pergamon Museum has been rebuilt once, destroyed during the Second World War and reconstructed, and has been undergoing comprehensive renovation since 2013.

The Pergamon Museum stands as a symbol of rebirth and continuous development.

We were tasked with the cleaning and retouching the exposed concrete surfaces in front of the entrance to achieve a unified appearance. The objective of these measures was to harmonize the color of the concrete, as variations had occurred due to uneven application of form-release oil and casting joints.

Since the concrete had turned out significantly darker than originally planned and intended by the architects it was part of the post-treatment process to brighten the surfaces using a glaze. In the column areas, several holes were also filled and selectively retouched to create a uniformed surface finish.
