The art of 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 Ventian plaster and Marmorino to the rugged look of textured polished plasters.
Polished plaster itself tends to consist of slaked lime, marble dust, and/or marble chips, which give each plaster its distinctive look. A lime-based polished plaster may contain over 40% or marble powder.
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.
