The speed with which the technical progress is moving, sometimes stunned. Building stores almost every week increase their range with a new building material. But there is something that never comes out of fashion, and no one century is used. I am now talking about natural materials, such as stone and building mixes with stone crumb.
Stucco with marble crumbs will always occupy one of the leading positions.
Features
Whatever materials for the walls of the walls existed, the plaster with marble crumb will always occupy one of the leading positions, and there is a logical explanation, namely, a huge set of advantages with which it is very difficult to compete with other materials.
Honestly, a separate article will be needed to list all the advantages of stone plaster, so I will dwell only on the most relevant.
Interesting! Decorative coatings using stone crumbs are used from the Middle Ages. The most famous material known since that time is Venetian plaster.

The advantages of plaster with marble crumb
- Complete resistance to temperature drops and does not have thermal expansion.
- Resistance to water and moisture. Marble plaster is not only not afraid of rains and snow, but it can be intensively soaked even with the use of strong detergents.
- High coating strength, which is very difficult to damage, but it is this nuance that often becomes a minus, as it is almost impossible to remove the coating with marble crumb.
- This material is completely neutral to all types of solvents used in construction. And including alkalis, which are most often found in repair or finishing work.
High coating strength, which is very difficult to damage
- There are no chemical components as part of plasters with marble crumb, which makes them completely safe and makes it possible to use this material in the decoration of the walls inside the apartment or at home.
- Very high vapor permeability. The argument that immediately raises marble plaster for several points above its competitors.
- A huge selection of colors and textures, which allows not only to create designer compositions, but also mix different types of plaster, creating a truly exclusive design.
- Stucco with stone crumbs has excellent adhesion with any surfaces, and with the necessary processing it can be applied even on metal.

Disadvantages of plaster with marble crumb
Unfortunately, even such a unique material, they are, and they can not be mentioned. And despite the fact that the mines of this coverage are significantly less than the advantages, they can to some extent limit the use of stone plaster.

Unfortunately, even such a unique material, they are, and they can not be mentioned. And despite the fact that the mines of this coverage are significantly less than the advantages, they can to some extent limit the use of stone plaster.- Pretty high value of the material.
- There are certain difficulties with applying, especially if the work is carried out with their own hands, and there is no appropriate experience.
- Large material consumption. On average, one square meter of the square leaves two to four kg of the finished mixture.
- Big weight coverage. The stone crumb creates an additional load on the walls and should be taken into account by applying it to lightweight structures.

Type of plaster with marble crumb
The main difference between the mixtures with marble crumb is not only the color, but also the size of the granules itself. The composition with different granules differs in weight as shown in the table below.
Plaster mixture | Granule size, mm | Weight per m2, kg |
Small fraction | From 1 to 2 | Less than 2. |
Average fraction | From 2 to 4 | 2.5-3. |
Large fraction | From 4 or more | More than 3.5 |
There is a difference in the binder component, which can act acrylic or mineral cement.
The main difference between the mixtures with marble crumb is not only a color, but also the size of the granules itself
In principle, it is possible to create mineral plaster with stone crumbs on their own, it is enough to add to the cement solution of marble granules and a puncturing paste, but this mixture will significantly give up quality. Since plasticizers and various additives, which not only improve the adhesion of plaster with the surface, are added to the finished plasterings, in addition to the main components, which not only improve its high-quality characteristics.
Important! An independently made mixture cannot comply with all quality standards, and therefore the positive nuances described above lose their relevance.
If you return to the conversation about the magnitude of the fraction, then some kind of mixture, there is no. It all depends on personal preferences, for example, plaster with a large fraction, most often used on the facades, it creates a feeling of solid stone coating, even when viewed from afar.
Smaller fractions, try to apply for interior decoration, where small granules in the coating will not rush into the eyes.

How to apply
In fact, the process of applying a mixture with a stone crumb is not much different from ordinary plaster, with the only difference that this material is more severe and immediately is a decorative element, which means that it does not require additional coating, and the errors will be clearly visible.
There is another substantial difficulty - fast drying. The mixture is frozen in about 30-40 minutes, and during this time it needs not only to apply, but also to sand. After overlooking the moment of drying, it will be useless to swee, and everything will have to start first, pre-removing the defective coating.

The process of applying a mixture with stone crumb, is not very different from ordinary plaster
So, the process of applying marble plaster consists of several stages:
- We remove all irregularities and damage from the surface. If there are cracks on the wall, they need to be expanded and laid a reinforcing grid.
- Born the wall with an antiseptic. The greater the soil, the better because the surface, before applying the solution, should have a humidity of about 10%.
- If the wall with strong defects, it is desirable to pre-align with simple plaster. In principle, this stage can be skipped, and it is done to save marble plaster, which is subsequently applied to a thinner layer.
The mixture is frozen in about 30-40 minutes, and during this time she needs not only to apply, but also sand
- Now we will drag marble plaster according to the instructions specified on the package and give the mixture to pamp for 10 minutes.
- We apply a mixture on the wall with metal culma moistened in water. The process should go from top to bottom, closing a small area for each approach.
- When the whole wall is covered, Okrew irregularity with a metal mesh holder.
Marble plaster is ready, and it remains to give it a carefully to dry out, which may take several days depending on the temperature.
