O’Sullivan Conservation was engaged to condition report, deinstall, treat, and reinstall a memorial plaque dedicated to public school teachers who fell in the First and Second World Wars. The plaque was carved in low relief from Queensland Maple and measured 1,450mm wide by 745mm high. It is displayed mounted on a wall at the AEU NSW Teachers Federation Branch in Surry Hills.

The condition assessment was completed on-site prior to the commencement of works. A materials lift was employed to carry the weight of the plaque during deinstall. It was removed from the wall and solvent testing was performed to determine the most effective means of removing the dust, dirt, overpaint, and accretions, as well as to ascertain the nature of the wood finish. Based on the tests conducted it was decided that water would be sufficient for most of the cleaning, with white spirits and cotton swabs used on the more stubborn areas. The plaque was then brush vacuumed and cleaned, and the surface was buffed. A light coat of fresh wax was applied, and the plaque was reinstalled.

Recommendations for future care and cleaning were provided to the client with the treatment report.
