The intervention of restoration of Centoris Palace in Vercelli , saw the Primat commitment for the study and the analysis of the historical surface, first through diagnostic investigations aimed at defining the state of conservation of the plasters (humidity, soluble salts, detachments of plasters), then through the study of the historical mortars and a formulation of an “ad hoc” mixture for restoration.
Through the collection of small original fragments of plaster, it was possible to analyze the binders, the aggregates, and the sands used to then identify the ideal formulation for the intervention of restoration.
Thanks to this targeted formulation and to the care of the support, the stuccos were perfectly integrated with the pre-existence, allowing to perform the veiling phase and painting reintegration with maximum transparency.
For this last operation, were used pure natural pigments , bonded with potassium liquid silicates.
The intervention allowed to restore the original pictorial decoration of the facade, restoring brillance and depht of the surfaces.
A restoration that was the result of a course of study and analysis conduced with rigor and competence by all the subjects involved and that allowed to enhance one of the most important Palace in Vercelli.
