Marble plaster – texture of the noble house (25 photos)
The use of natural stone, such as marble and granite, creates a rich view of the monumental buildings, differing in their strength and outer aesthetic. Apply for finishing natural stone buildings - an expensive and time-consuming pleasure. So now use imitation natural stone surfaces, as created by the marble plaster.
What is marble plaster and its properties
The name of marble decorative plaster filler received thanks from chips made of marble dust and connected to ground limestone. The structure also includes:
- synthetic acrylic copolymer in aqueous emulsion form;
- water-repellent and antiseptic, and other additives;
- preservatives and coloring pigments.
Due to such coating composition based marble chips attached to the surface unique texture and used as finishing. This material has excellent adhesive properties and good adhesion to brick, concrete, gypsum and other surfaces. Decorative plaster "marble chips" does not require labor-intensive work and can be used for decoration of walls kitchen, bathroom and other rooms inside the building, as well as for facing the outer sides of buildings. This finish gives the following surface properties:
- high strength and hardness, providing resistance to mechanical damage;
- resistance to climatic influences: moisture and temperature changes;
- good water vapor permeability, allowing the walls to "breathe";
- resistance to UV, chemical agents and fire;
- environmental security;
- a variety of texture and color.

Types of marble plaster
The finishing material based marble chips are classified depending on the filler fraction. Crushed marble grains should be approximately the same size, so pre-calibrated crumb. This is to ensure that the surface is coated with a crumb, I had a uniform thickness and is flat.
There is a division of the following plaster largest grain:
- fine grain having a grain size of 0.2 to 1 mm;
- medium-grained (fraction 1 to 3 mm);
- coarse (fraction of 3 to 5 mm).
From the grain size fraction depends assignment marble coating. For finishing indoor use fine material and for decorative coating facades - medium-grained and coarse-grained structure.
Divided plaster with marble chips and a color indicator. Whereas previously only been applied crumb having natural shades, often non-uniform in color, but now uses a plurality of tinting callers who give the filler shade of natural character or color other than natural marble. To do this, use light-resistant pigment dyes, not fade from sunlight and keeps the original color of from 15 to 25 years coating operation.
The use of tinting allows callers to create a wide variety of finishing this material.
There are also different types of marble mixtures whose composition is different not only grain fraction and its hue, but also used filler composition. Such materials include granite and marble plaster, Venetian mosaic and varieties.
The composition of the filler Marble mixture contains besides granite marble chips fraction. This greatly affects the characteristics of the coating durability, making it resistant to mechanical damage. However, addition of granite chips in the mixture affects the degree of adhesion to the polymeric binder component, it becomes lower.
Exterior marble plaster is mostly granite and marble because of its high mechanical stability. Use it also for the finishing of the outer surfaces of the foundation and arch designs. In this case, to select economical materials in which the binder component is a cement M500 white color.
Marble Venetian stucco as filler comprises marble dust fraction with addition of granite, quartz, malachite or other stones. Quantitative mixing ratio significantly affects the quality characteristics of the coating and its decorative appearance. The finer the milled components, the drawing evenly, and the surface smoother.
Venetian variety binder material until some time been slaked lime. With modern manufacturing techniques in acrylic resins are more commonly used as a binder. It is added as a pigment both organic and inorganic origin.
There are several types of Venetian plaster mixture composition and density. The higher the density, which is manifested by its tackiness in the finished form, the smoother and higher quality coating is obtained. The surface to be coated, this material must be carefully aligned to a smooth state, or marble dust with bright highlights on drying the composition will give all the problem areas.
Venetian stucco mixture is preferably used for the decoration of surfaces in antique style.
Mosaic plaster marble is a material which is a mixture of filler chips of different colors of marble, granite, quartz, malachite, lazurite. Using different color stones, get a unique view of the mosaic finish. Crumb may also be applied one of these components painted in another color different from the natural color fractions. Color excipient is connected via an adhesive based on the acrylic component.
Using the mosaic drawings can be made in the form of a panel on a wall. Mosaic kind often used for decorative interior of individual fragments of niches, columns, arched constructions.
Technology use marble plaster
Quality finish and appearance of the surface covered marble plastering, depend upon the use of technology. In this case, it must follow the following operations:
- surface preparation;
- marble surface decoration layer.
Let us see how these steps are carried out works.
Any surface on which is applied decorating layer must be cleaned of dirt and grease. Cut down or bring down the hammer all the protruding parts. Cracks and dents to cover composition having good adhesion to the substrate. In the case of large irregularities need to pave the reinforcing mesh. After applying the roughing fillings, a base should be roughened.
For coarse marble plaster applied to the façade, minor cracks and defects are allowed, as they are easily closed by means of a thick decorative layer. Perfectly smooth surface is required only when applied Venetian mixture.
The primer layer aligned necessary to improve the adhesion of the decorative material with a base to prevent delamination of plaster after drying. Before applying the primer is necessary to check how well it is absorbed by the surface layer. Marble coating will stick firmly to the wall with complete evaporation of water from the solution. If the walls are coated with a primer before that, the water from the plaster mixture is absorbed in their surface layer, which leads to the deterioration of adhesion.
By primer can be waived only in the case of a wall coating material, which is almost does not absorb moisture. This is verified by a trial application of the primer. If a few hours after its drying is produced brilliant film, then step priming base can be dispensed with.
Glossy basis in this case it is sanded with a view to roughen the surface layer of the base for better adhesion of decorative plaster with him.
Decorating marble layer
Application of marble plaster base carried on a spatula, whose size is 30 cm or more. The larger size is used when working with large squares façade.
After application to a wall portion of the mixture is spread evenly thereon with sufficient force to ensure good adhesion to the substrate. It is important to finish without stopping to finish one wall, without waiting for drying. Then the joints of extended portions will not be visible.
To ensure color uniformity of plaster in the interior is recommended to apply to the base paint color close in tone to the color of the marble chips. Then you will not see the clearing of dark and light background. Buy stuff one shade better at the same time in one place. This will also save on marble plaster. A particularly important use of base paint for finishing Venetian stucco. Otherwise you'll have to cover the surface of the plaster in several layers.
