Marmorino Classico (Roman Plaster)

A Natural Mineral Product

Approved as an Eco construction material in Europe with optimum breathability 90% – 95%, prohibits mold forming bacteria that creates mold, 0% – 1.85% VOC (<30g/lt).

Marmorino plaster has been in use since Roman times, and is in fact mentioned by the Roman author, Vitruvius, in his writings 100 BC, “De Architectura”. Other cultures such as the Egyptians, Ancient Greeks, and the Etruscans, used tinted Marmorino to decorate walls and is still existent on intact walls in these historical sites. It was used as a finish wall surface on Roman Lime Cement, which was applied 10 centimeters up to permit the absorption of mineral salts from humid walls in contact with the ground, to provide transfer of moisture to the outside, maintain breathability, and structural stability. Marmorino plaster is an ideal plaster that can withstand centuries of moisture when applied to the external wall surfaces, and internal wall surfaces.

This technology as with Antica Calce disappeared at the end of the Roman Empire and did not resurface until the Middle Ages. Marble plaster in this time period was used as the first base coat for eventual fresco painting. This use of Marmorino plaster, curiously enough, in this time period was limited to the area of Veneto in northern Italy, possibly due to influences from their origins in the Eastern Roman Empire.

In the 1400s AD, during the Renaissance, there was a new effort to design and build based on Roman Architecture. And in this period re-began the use of smooth finished walls with mineral colors integrated in the lime plasters, to create the undulated colour effect commonly associated with Venetian Plaster. By the 1500s, Andrea Palladio had brought the use of Marmorino to its maximum exposure collaborating with Alessandro Vittoria as a master plasterer to achieve the fame that Venetian Plaster endures until today. The Inactive Lime (Slaked Lime), as found in Antica Calce (Antique Lime Wash), Marmorino, and Venetian Plaster acts as an anti-mold/fungus prohibitor. Being a porous material, but with an extremely hard surface, and used in conjunction with other porous wall support materials, Marmorino and all Slaked Lime Products used in traditional Roman composition have incredible capacity to absorb moisture and wick that toward the external walls of the house.

Absorbing oxygen and humidity, Marmorino and slaked lime products are proven to absorb carbon monoxide and other toxins in your house and passively remove them toward the outside environment. It is for this reason that the EEC has mandated eventual building code requirements for any Eco Certifications to use these natural materials for the purpose of self cleaning, and breathability. Surprisingly enough, with the right wall construction and use of these materials, Slaked Lime products have natural climate controlling aspects. You will have noticed this with any travels in Italy upon entering a restored Roman or a Renaissance Villa.
