The restoration of the fresco copy began with surface cleaning. Where there was good attachment to the substrate, the results were satisfactory. Where there was flaking, however, cleaning was difficult due to the lack of cohesion, so the surface was first consolidated.
There was also some repair in areas of extensive loss of the painting surface. The repair helped increase the cohesion and retention of the layers of the copy.
The materials used for the repair were gypsum, a material related to the construction technology of the fresco substrate, and acrylic filler, suitable for filling cracks due to its elasticity. Finally, where the painting surface was lost, powder pigments were used with acrylic mortar, in the same colour as the existing paint.
