Reason for treatment
Organics: Clean and consolidate wood and gesso if necessary.
The surface of the wood and gesso is slightly dirty.
The gesso is lifting from the surface of the wood. There also appears to be some fresh losses along the edges of the extant gesso.
The surface of the gesso was lightly cleaned using small cotton swabs on cocktail sticks lightly moistened with saliva. The surface was then cleaned using cotton swabs lightly moistened with deionised water.
The edges of the gesso were consolidated using Lascaux Medium for Consolidation (Lascaux 4176 acrylic copolymer dispersion) applied with a small sable brush. Any excess was removed using small cotton swabs with saliva. The larger loose fragments of gesso were adhered using 10% Paraloid B72 (ethyl methacrylate copolymer) in 50/50 Industrial methylated spirits (ethanol,methanol) / Acetone (propan-1-one/dimethyl ketone) applied with a brush. Any excess was removed using small cotton swabs lightly moistened with acetone.
