Hirst Conservation undertakes the recording, analysis and conservation of wallpaintings from the Middle Ages to the 19th Century, in various techniques from ‘true frescos’ to oil paintings executed on plaster. The dedicated team includes conservators who specialise in the treatment of wallpaintings, trained to post-graduate level.
The services offered for the treatment of wallpaintings include:
Comprehensive condition surveys, including photographic and diagrammatic recording. This includes assessment of previous treatment documentation and archival records
Analysis of the fabric to inform and facilitate treatments, including the measurement of moisture levels within the stonework
Discrete sampling of the plasterwork to determine soluble salt content, hygroscopicity and aggregate/binder content
Environmental recording of relative humidity, absolute humidity (vapour pressure), temperature and dew points, which have an important bearing on the stability of the wallpainting
Treatments to the substrate include:
Structural consolidation of areas showing granular disintegration
Consolidation of flaking, scaling and delamination between plaster layers
Mortar repairs to losses within the plaster and to fractures
Treatments to the paint layers:
Consolidation of flaking and/or powdering paint layers
Removal of surface coatings including dirt, over-paint and inappropriate retouching
Sympathetic retouching of losses
