The restoration: reasons and objectives

The restoration is necessitated by acute adhesion problems between the paint layer and the canvas. The black areas, which were applied with diluted paint, contain insufficient binding agent and are all at risk. Tiny areas of the paint layer are already being lost.
The white, somewhat more impasto areas exhibit minute craquelure. Here too, flakes of paint are lifting and coming loose.
To prevent the paint loss from progressing and preserve the painting in its current condition, extensive consolidation of the paint layer is essential.

Before this work can begin, tests are being carried out to establish which consolidating agent and form of application will achieve the desired effect. The surface of the very matt black paint is exceptionally sensitive. The challenge is to find a medium that will not leave glossy residues or cause colour saturation.

Once the conservation is complete, areas of paint loss will be coloured to match the surrounding paintwork, improving and/or restoring the original aesthetic impression.

New findings will be documented on the website.
