Paints and coatings based on lime are the best solution for the restoration of historic facades and for the protection from atmospheric and polluting agents. The recovery of facades of historical centers requires the application of natural and ecological products that can restore the ancient effect of the masonry, maintaining its breathability for a long time. In the past, the construction techniques that included the use of lime were known and handed down by the workers, who knew how to use the materials, treating them wisely. Unfortunately, over time, this wealth of knowledge has been disappearing due to the use of new coatings, less effective than lime in the case of restoration and decoration. With the Calce Line, Paulin wanted to create a series of ready-to-use products that draw on tradition, expressing the technology of the most innovative paints. The excellent adherence of this line is a consequence of the natural reaction of the slaked lime with the carbon dioxide present in the air: the formation of calcium carbonate crystals allows the paint to hook firmly to the plaster and to protect for a long time the masonry. Breathable and resistant to ultraviolet rays, these products make it possible to obtain a rich palette of colors with interesting chromatic characteristics, impossible to achieve with other paintings. The final effect is ancient or rustic, but with modern features.
