Abstract

The colour of historical façades as well as the traditional plasters which support it, is nowadays considered as a material full of historic significance and of cultural testimonies. The operative instrument defined by the law which is devoted to provide guidelines for the conservation of the historical facades is the “Colour plan”. The content of the Colour plan and the methodological approach for its definition are topics currently under discussion, even if the importance of the diagnostic aimed at the material characterization and at the evaluation of the state of conservation is widely recognized. Moreover, the preservation of the historical centres cannot be only handed by the Colour plan itself, but it should be faced with a wider and more comprehensive approach: the colour plans are currently included into the general “conservation and maintenance plan” of the historical centre. The “Colour project” therefore is necessarily based on a thorough historical research both of direct and indirect source; it then proceed with a geometrical survey at a single-building scale; it studies the constructive techniques, the materials used during the different periods and the chromatic/decorative value of the façades and, finally, it evaluates the state of conservation. As result of a multi-disciplinary methodology, the planner can obtain an organic vision of the updated situation and define the most suitable plan of programmed conservation. This paper will discuss a selection of innovative diagnostic techniques for the characterization of the facade materials, for the evaluation of their state of conservation and for the measurement of their colorimetric parameters before, during and after the project conservation and planned maintenance. These techniques are performed both in situ and in laboratory and are fundamental tools during the whole conservation activity: preliminary diagnostic, survey during the preservation operation, middle or long-term monitoring of the efficacy of the preservation treatments and techniques.
