Polished Plaster is not only the name of the material, but also a special technique for applying it. It is used to obtain a coating that simulates polished marble on the walls of facades and in the interior.
Two types of Polished plaster:
Acrylic A binder is an aqueous acrylic latex
Polished plaster is applied in several layers (usually 2-5), with the compaction of each layer (but except for the first layer). Layers can be monochrome or with different shades. For added protection and a more polished surface, Polished plaster is coated with wax.
It is believed that the birthplace of Polished plaster is Venice. In fact, such a technique for applying plaster began to be used in ancient Rome, from about the 900s BC. In those days, marble was used as the main building material. In the process of manufacturing marble blocks and slabs, a lot of marble dust remained. We noticed that when marble dust is mixed with slaked lime, a material is obtained which, under the influence of air, becomes stone (carbonized). It becomes similar to marble in its properties and appearance. To improve the properties of the composition began to add clay. To obtain color shades, natural dyes began to be added to the plaster, minerals, plant juice, animal blood. Grab more info about the right services right here.
The best Usages
Using this plaster of this plaster it became possible to obtain a beautiful seamless coating that imitates polished marble. Over time, they noticed that in addition to durability and aesthetics, the plaster tolerates high humidity well, is not subject to mold and rot.
- The influential European architect Andrea Palladio gave a second life to Polished plaster in the mid-16th century. Andrea Palladio is the creator of the classical architectural style of Palladio. The book “Roman Antiquities” published by him became a manual on ancient architecture until the 18th century. In this Renaissance, the well-known history of Polished plaster began. Due to the location of Venice on the water, in a climate with high humidity, ordinary materials quickly lost their properties on the facades of buildings. The ideal material for wall decoration was Polished plaster.
Since during the application of the Polished plaster, each layer is compacted, the coating is durable, not subject to mold and rot. When it becomes necessary to restore the walls, the next layer of Polished plaster is simply applied. As a result of overlapping layers, a coating with the effect of “depth” and naturalness, similar to marble, is obtained.
Differences between calcareous and acrylic Polished plasters:
Currently, along with lime-based Polished stucco, modern Polished stucco based on water-based acrylic latex is used. Such Polished plaster is easier to apply, more durable. Unlike calcareous Polished plaster, it has almost unlimited possibilities for tinting, including in very saturated and vibrant shades. They are environmentally friendly, non-toxic.
