Venetian Plaster – Polished Plaster
Polished plaster is a term for the finish of some plasters and for the description of new and updated forms of traditional Italian plaster finishes. The term covers a whole range of decorative plaster finishes – from the very highly polished Venetian plaster and Marmorino to the rugged look of textured polished plasters. Polished plaster is mainly used internally, on walls and ceilings, to give a finish that looks like polished marble, travertine, or limestone, and is usually sealed with a protective layer.
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 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 coloured using natural or synthetic colorants. The ability to tint Venetian plaster is especially helpful when a specific colour of “marble” is desired, or when a colour that does not exist naturally is wanted.
