Plasters used to be made from sand, cement, and lime; but, in the last fifty years, these ingredients have been replaced by gypsum, which results in a plaster that is substantially lighter. In addition to that, there is a new product on the market called “marble plaster,” which is colored and has the appearance and texture of marble. However, “marble plaster” or “venetian plaster” has been around for over 500 years, making it neither new nor contemporary. It was in Venice, Italy, where the venetian plaster technique was developed. The term “v/p” refers to a number of different plaster finishes that were developed in Venice in the 1500s. In order to prevent structures from sinking into the mud, architects and builders were required to locate a lightweight alternative to marble. A color pigment is combined with lime putty that has been blended with marble flour, and then the mixture is placed in anywhere from two to seven extremely thin layers. The last coat is given a brilliant sheen by using a steel trowel to buff it. After that, the wax is polished and applied. The first kind of contemporary Venetian plaster is called venetian stucco, and there are two more forms. This is the finer of the two and is used to create a pattern that looks like marble by applying it in a random fashion. The second option is marmarino, which is characterized by a coarse aggregate. To get the appearance of stone, this is applied in layers and may be sculpted in a variety of various ways. As long as the substrate is level and the appropriate surface preparation has been carried out, v/p may be applied to almost any substrate. It takes a lot of experience to acquire the correct finish, and various plasterers will produce finishes that seem different from one another.
