Condition
After nearly 150 years, the outdoor statues had been eroded and stained by rain, weather and bird droppings, as well as being covered in leaf litter from nearby trees, biological growths and spider webs. Some of the statuary had graffiti, and some had highly polished surfaces from repeated manual contact and climbing by the public.
The indoor statues were more protected from the elements, their condition mainly affected by dust, bird droppings, spider webs and erosion by manual contact.
Treatment
In April 2021, ICS completed maintenance conservation on the 21 statues. The objective was to clean the statues and remove the dirt before it could stain the marble. The treatment methodology included dry manual cleaning and wet pressure washing, followed by an application of biocide to treat ingrained biological growth.
Outcome
Ballarat’s heritage-listed marble statues are now regularly maintained to preserve their value and beauty for future generations.
