RESTORATION OF PAINTINGS

A paintings restorer is an expert who deals with works of art done on canvas, wood panels and polychromatic objects. The repair of damage caused by pollution, natural ageing or other traumatic events, such as inadeguate or incompetent previous restoration work constitutes the bulk of his or her work. After consulting academie, iconographic and photographic resources, the restorer draws up a restoration plan and only then intervenes on the work of art.
