Venetian plaster is a wall and ceiling finish consisting of plaster mixed with marble dust, applied with a spatula or trowel in thin, multiple layers, which are then burnished to create a smooth surface with the illusion of depth and texture. Venetian plaster techniques include marmorino, scagliola, and sgraffito. When left un-burnished, Venetian plaster has a matte finish that is rough and stone-like to the touch.
When applied correctly, Venetian plaster can be used to create a highly polished, rock-hard, marble-like finish. Venetian plaster is especially useful on surfaces where marble panels could not be installed easily, and on surfaces that would be too expensive to have carved from real marble such as columns, corbels, and curved walls.
Venetian plaster can be tinted, or colored using natural or synthetic colorants. The ability to tint Venetian plaster is especially helpful when a specific color of “marble” is desired, or when a color that does not exist naturally is wanted.
Marmorino Veneziano is a type of plaster or stucco. It is based on calcium oxide and used for interior and exterior wall decorations. Marmorino plaster can be finished via multiple techniques for a variety of matte, satin, and glossy final effects. It was used as far back as Roman times, but was made popular once more during the Renaissance 500 years ago in Venice.
Marmorino is made from crushed marble and lime putty, which can be tinted to give a wide range of colors. This can then be applied to make many textures, from polished marble to natural stone effects. Widely used in Italy, its appeal has spread through North America especially, but now worldwide. Because of the hours of workmanship, the pricing places it in the high-end market. However, many examples can be seen in public buildings, bars, restaurants, etc.
Its waterproofing and antibacterial qualities as well as visual effects have also made it very desirable for luxury bathrooms, honeymoon bedrooms and other wet areas. Not confined to interior use, it can be seen on the exterior of many buildings to great effect.
