F.J. Martyn Roberts painting Evening (Mt Coot-tha from Dutton Park) 1898 is an important Brisbane landscape so a six month project carrying out a delicate conservation treatment to clean and restore this work was scheduled. Due to the aging process of the upper varnish layers, and the restoration treatment that had taken place before the painting came into the Gallery’s Collection, the work required careful removal of the aged, discoloured varnish layer and old restorations that has accumulated on the surface.

Cleaning the painting with small conservation tools and gel carefully allows the removal of the upper varnish layer without disturbing the original paint layers below, thus revealing the original colours and tonality of the painting. The cleaning took some weeks to complete, followed by the stabilisation of the paint layers – varnishing and the filling and retouching any losses in the composition.
