Cleaning and painting the facades of Palazzo Bacialli

Palazzo Bacialli is a fine example of 18th-century civil architecture. It consists of four above-ground storeys, the ground floor of which has a portico with seven arches in continuity with the entire street front. The cusped façade on Via delle Lame follows the course of the street and with its window frames and moulded stringcourses, typical of historical architecture, shows greater architectural value than the more modest façade on Via Otto Colonne.
Both façades showed evident and widespread degradation, with recent interventions of repainting with vinyl-based paints to hide the vandalistic inscriptions made with spray cans. After stratigraphic investigations, the plasters were beaten to probe the consistency of the substrate and then hydro-washed to remove surface dirt deposits. The old paintwork was then scraped off, and a pointwise smoothing of the old plasterwork was applied with the same mortars and paintwork. All the moulded projections were protected with a final water-repellent treatment of an oil-hydrophobic breathable impregnating product based on fluorinated polymers in water dispersion. The eave overhang was sanded, impregnated with anti-parasitic liquid and painted with satin synthetic enamel while checking the correct connection between the waterproof layer and the eaves.
