Condition
ICS conservators assessed the mosaic and determined that overall, it was structurally sound, and was well-bonded in a cement substrate. There was some cracking of the slab and general abrasion due to wear and tear of the glazed tile surfaces in a pedestrian traffic area.
The large panel had a small amount of tile loss and a network of fine cracks. The cracks ran northwards from a central point, and while no tiles were loose, there were small tile and grout losses along the cracks.
The smaller panel had some cracking and some small loss of surface cement and tile. These cracks were considered when coming up with a methodology for lifting the mosaic. There were also some characters on the mosaic that were missing eyes due to missing resin.
Treatment
ICS and the client considered the artist first and foremost, as a living and recognised indigenous Warimiri artist, and felt strongly that Yumbulul was the only person with the cultural permissions to produce the artwork and should continue to be consulted with matters pertaining to the artwork.
Upon consideration and research, the client decided to proceed with a conservation treatment in only one section with damaged tiles.
ICS undertook a wet and dry localised clean to reduce the adherent and loose dirt deposits, and then carefully filled and colour-matched the damaged tiles.
Treatment outcomes
Repairing the mosaic to reveal its original design and glory has made a large visual difference to its state, so that it is intact and secure. The integration of the repairs and fills to match them with the existing surface has made the repairs cohesive and blend in.
The mosaic has responded well to treatment and is now looking in great shape.
