Description

The interiors of Transport House, located in Macquarie Street, Sydney, are distinguished by their use of marble and scagliola marble wall finishes. Scagliola (from the Italian scaglia, meaning "chips"), is a technique for producing architectural elements that resemble marble. The scagliola finishes at Transport House had had a number of varnish and wax finishes applied over the years, resulting in a darker colour than originally intended. In addition, some the varnish applications had saturated into the scagliola causing dark patches. ICS was commissioned to undertake conservation work to return the scagliola close to its original condition. Thus the applications of additional varnish layers were removed and damage repaired, but cracks in the scagliola tiles were seen to be part of the ageing process and were left untreated. 

Scope

  • Develop appropriate conservation strategy
  • Undertake a trial clean and treatment to assess feasibility and limitations of proposed treatment
  • Sand, clean and polish heritage scagliola
  • Supply new scagliola tiles to match original tiles
  • Infill patching of in-situ scagliola on columns in main building atrium area
