Salt conversion, backfilling, and back anchoring: the securing of the painted ceiling of the Red Hall in the Neues Museum, Berlin (original) (raw)

In connection with the restoration of the Red Hall in the Neues Museum, located on the museums-island in Berlin (2006-2008), a procedure for salt conversion and backfilling of hollow painted plaster areas with the help of low-pressure injection technology was developed and successfully implemented. The precipitation reaction resulting from the salt conversion was assessed using electrical conductivity measurements and identification of the precipitate by x-ray diffractometric analyses (XRD). For an additional securing of the plaster areas, an extensive injection was carried out and a suspension system for the back anchoring in the hollow pot bricks was developed and implemented.
