The traditional color of Venetian facades is a pinkish-brown hue, and there is a unique reason for this. In the past, the facades of this old city were often coated with a Terracotta plaster made of lime and clay. The clay was sourced from old bricks and roof tiles, because exporting waste or importing raw materials was very costly in this city surrounded by shallow waters. This plaster was a derivative of an ancient Roman plaster, which was made by combining lime with Terra di Pozzuoli (today pozzolana), an earth containing a high percentage of clay. Indeed, Romans had discovered that the addition of clay conveys hydraulic properties to lime. This type of lime hardens even underwater, making it ideal for building in the midst of rivers and in the presence of high humidity, such as in the city of Venice.
LimeClay is the improved version of this terracotta plaster typical of the Venetian architectural tradition. It is an ideal plaster for exterior walls due to its incredible durability and moisture resistance. LimeClay, however, is also a healthy choice for indoors, as it helps regulate the balance and healthiness of the environment. How is this possible?
LimeClay Plaster is produced with hydrated lime and baked clay. The benefits of using clay plaster are well-known. Clay regulates relative interior humidity and protects the environment from infectious bacteria. Moreover, clay produces negative ions. Negatively ionized oxygen molecules attach themselves to red blood cells, which improves blood quality.
