"... In order for plasters to have a good duration and not be defective, roughing with cocciopesto and lime is required, which acts as a bond between the parts" (Vitruvius "De Architettura", book VII chapter IV, I century . AC). For 2000 years we have been aware of the processes that allow clay, baked and ground or obtained from volcanic deposits, to provide optimal solutions to the particular problems of hydraulic engineering applied to the construction of aqueducts, cisterns, fountains and above all thermal complexes from highly sought after technical and functional solutions. Recent studies, performed on historic mortars, confirm that aerial mortars can have a hydraulic character if the compound has cocciopesto. Hydraulicity is given by glassy components, contained in the clay, such as silicates and aluminates which, combined with lime, give the mortar resistance in damp environments and greater mechanical performance.
The plaster does not only play an essential role in the architectural definition of the building, but it assumes decisive importance in countering degradation actions. The rustic wall is more easily attacked by atmospheric agents, the cladding is a barrier against water, capable, at the same time (due to its permeability to water vapor, that is for its ability to "make breathe the wall ") to help maintain the thermodynamic balance between the building and its environment. Thus on the basis of the Vitruvian indications, the plaster was prescribed in several layers, so much so as to imagine it as "the skin of the building". Each layer, like the skin, contributes to fulfilling specific functions, performance and aesthetic characteristics. The "Cocciopesto Guglielmino" plaster, based on natural hydraulic lime and cocciopesto, is made up of three well-cohesive layers that together form a "plaster system" capable of protecting and embellishing the walls. It stands, in its own right, in the tradition of natural plasters, with which skilled craftsmen and artists have characterized, over the centuries, the colors of the historic centers of our country. It is particularly suitable for the recovery and restoration of buildings in historic centers and for new architectural solutions.
