Surface coatings

Sargent appears to have applied coatings to the murals to modify tonality and gloss. This surface coating material, along with coatings applied by past restorers, has discolored over time and obscures the murals. Past restorers applied coatings to saturate the paint surface, and in a few areas retouching to conceal damaged areas. This retouching has also discolored, further disfiguring the murals.
