Before the removal of the Riza, the most fragile areas will be secured with small strips of Japanese paper and adhesive.
The metal is attached to the wood support by about twenty motley and rusty nails. They will be removed gently with a small clamp after applying a sobering to their base.
The Riza removed, the total area of the work is accessible. It will then be necessary to remove the microorganisms, to reposition as best as possible the fragments of usable pictorial layer and to apply a fungicide on the entire colored layer.
The wood support must also be treated with insecticide injections and a synthetic resin.
At the end of these treatments, the consolidation of the painting can be carried out safely fraction by fraction. It will be a question of injecting between the pictorial layer and the wood support natural glues and then reactivating them hot. This operation makes it possible to restore the flatness and adhesion between the pictorial layer and the support of the work thus ensuring its durability.
