Hirst Conservation specialises in the surveying and treatment of decorative and figurative gilded and painted surfaces found, for example, in historic homes and churches.
The stability and survival of the paint layer and substrate can be detrimentally affected by numerous factors such as deficiencies in the building envelope (leading to water ingress, the formation of salts, and cracking), the presence of inappropriate non-original materials, fluctuations in the environment, pollution, vandalism, accidental abrasion or even an inherent flaw in the original techniques used by the artist.
Approach to conservation treatment:
A visual examination of the decorative surface, as well as trials to formulate an appropriate methodology for treatment, are combined with a technical inspection using UV and raking light. Historic paint research may sometimes be necessary.
The services offered for the treatment of decorative surfaces include:
Consolidation of flaking paint
Removal of surface dirt and debris using dry, solvent or aqueous methods
Removal of inappropriate coatings such as over-paint and discoloured varnish
Stabilisation and filling of cracks and losses in the substrate
Filling of losses in the paint/ground layer
Re-carving or re-modelling of missing elements of decoration such as bosses, ribs etc.
Retouching of areas of paint loss or abrasion
The application of isolating and final varnishes
Hirst Conservation specialises in the conservation of oil and water gilded surfaces on objects ranging from frames and furniture to historic decorative interiors and architectural features.
The services offered for the treatment of gilded objects include:
Assessment of condition and examination to determine type of gilding and causal factors of deterioration
Consolidation of areas of flaking
Filling and preparation of substrate (gesso or plaster), including the application of bole or appropriately-coloured base coat
Removal of bronze paint and inappropriate layers
Re-gilding, where appropriate, using silver or gold leaf (22 carat or higher and colour matched to surviving), applied either as loose or transfer leaf
Oil or water gilding techniques, used as appropriate
Complementary techniques such as burnishing, stamping and scraffito
Distressing and/or toning down of new gold to match existing
