Course topic / Argomento del corso

Removing retouching layers on easel paintings is often a complex operation, due to the tenacity of aged binders and the fact that they often overflow onto the original paint as well. The complexity increases when their location is then extended in the form of overpaints that cover the entire surface, as often seen in the case of polychrome wooden sculpture. The presence of oxalates, formed by the decomposition of the original oil and protein binders, further complicates the removal.

We will discuss four strategies that can be effective in removing added layers from retouched and overpainted areas, avoiding the use of highly toxic paint removers and strippers. These will be the topics addressed: how to increase the solvent power of Ethyl Lactate; the removal of layers in the presence of oxalates; the use of rigid oil-in-water polymer emulsions; a safer use of the dipolar solvent DMSO.
