The Venetian plaster is one of exclusive types of decorative coats of walls and ceilings. Process of its drawing is very labor-consuming, but the result is worth of the spent efforts.
Composition of the Venetian plaster
The Venetian plaster represents mix of acrylic resins and polymers, plaster, marble dust, lime and additional additives. The exact composition of the Venetian plaster is not disclosed, however it is not identical at various producers. The Venetian plaster will be polymerized in the open air, without allocating in the course of toxic gases. Putting plaster is carried out in several layers therefore the surface takes form of marble cut. In different types of the Venetian plaster not only the structure of components and their proportion, but also extent of crushing of stone powder varies. The fine crushing gives as a result glossy surface with gentle marble stains, powder of coarse grinding allows to achieve effect of hewn stone wall.
Coloring of the Venetian plaster
Initially modern Venetian plaster is produced white and painted just before drawing or after it. As coloring pigments extracts from color soil can be used though recently synthetic dyes gain the increasing popularity.
Paint the Venetian plaster, as a rule, in vibration mixers. They allow to achieve uniform distribution of pigment on structure. If as envisioned by designers marble has to have white streaks, in the Venetian plaster dye is stirred by means of the construction mixer. The applied plaster can also be painted and even to draw on it certain compositions, but the drawing is covered surely with hydrophobic structure: wax, gel or thin translucent group of the same Venetian.
Drawing decorative coat
Process of drawing decorative coat quite difficult also demands certain skills. It is possible to cover with the Venetian plaster any types of walls and ceilings, but for the purpose of decrease in consumption of expensive material the surface is prepared at first: putty, ground, sometimes paint. Also on the Venetian plaster cracks in the wall will surely appear therefore under putty layer usually stack fiber glass grid. Apply the Venetian plaster with dabs, allowing to dry completely to each layer. The structure has transparency therefore on crossing of dabs more dark sites are formed. It is also possible to use plaster of different tones or even shades. The finishing layer is strongly rubbed sometimes with the steel palette because of what the acting parts of relief surface turn into dark marble streaks.
