You can add a beautiful appearance to the facade of the house with the help of various finishing materials. These can be brick, wood, siding and plaster. It is noteworthy that it is the last option that is considered the cheapest and is used more often than others. But at the same time, it requires certain labor costs. But such a coating looks pretty nice.
Mineral facade plaster, which has a rich history, is able to radically change the appearance of a house, while being considered the most durable type of facade coating.
Mineral facade plaster
Plaster as a finishing material for walls and ceilings has been used for thousands of years and is still considered, perhaps, the most universal way of decorating various surfaces. She saw the light during the heyday of the Roman Empire, when plastered walls were very popular among the wealthy. However, the Romans of average and low income could also afford to arrange housing with the help of plaster.
It is interesting that even decorative finishing plaster appeared precisely in Ancient Rome, since during the work on the manufacture of large stone blocks, a large amount of small stone debris was obtained, and the ingenious Romans decided to turn it into decorative plaster.
It began to be used to decorate walls and ceilings in temples.

Now there is a huge selection of plaster on the market of building products, all sorts of varieties and color variations of this material appeared. The easiest way to classify them is by the substances that are used in their manufacture.
From this point of view, plaster is:
Each of these types has its own characteristics and features, which are associated not only with the appearance of the material, but also with the technology of application to the working surface.
Types of structures of facade plaster
At the heart of silicate plaster are components of mineral origin. And the binder is potassium water glass. This material is characterized by low elasticity, has high vapor permeability, is not afraid of dirt, and therefore remains clean for a long time, which is why the walls do not require special maintenance.
Silicate plaster is often used on difficult-to-work surfaces, such as cellular concrete, shell rock. It can have a lot of shades and is sold ready-to-use.
The main disadvantage of silicate plaster is the likelihood of small cracks on its surface.

Acrylic plaster is a plastic material that is resistant to sudden changes in temperature. often used specifically for finishing the facade of buildings.It is easy to give it the desired color using colors. It has excellent vapor permeability, elastic, parasites and pathogens do not live on it.
Also, it is acrylic plasters that are especially abundant on the market.

The main disadvantage of using acrylic plaster is its "magnetism" in relation to dirt. All dust will surely settle on surfaces covered with this finishing material. Fortunately, it is easy for the plaster to return its former appearance - you just need to rinse the wall with water, as dirt does not eat into the surface. Also, acrylic plaster is quite difficult to apply due to the high drying rate, therefore, it should be covered with it, if possible, the entire wall at once, taking breaks only when moving to another plane.

Silicone plaster is considered the most expensive. Thanks to the silicone base, any filler can be added to it, for example, quartz sand, due to which a surface plastered with a material such as real stone looks. Silicone plaster does not attract dirt, is elastic, has excellent vapor permeability.

Since the article deals with mineral plaster, we will talk about it separately. This building mixture is often called cement, since the binder in it is precisely high quality Portland cement, as well as lime.
The composition also contains various filler minerals - these are crumbs of granite, quartz or marble. Thanks to this combination of components, a very reliable and high-quality building material is obtained, which is excellent for both interior and exterior decoration of buildings.

Note! There are facade mineral plasters based on silicates, but they are extremely rare due to the high price of the material.
The main advantage of mineral plaster is its strength.
Such a coating is made for many decades and regularly, without crumbling, serves a person. However, this material is more expensive than the same acrylic plaster. Fortunately, this building mixture pays off quite quickly during operation - it will take a long time to re-plaster the walls. Mineral plaster has excellent water vapor permeability.
Features of mineral plaster
There are quite a few mineral plasters on the market, therefore, among all the variety, you can choose the ideal options for finishing and basement, and walls, and other surfaces.
The material can differ not only in color, but also in the size of the filler fractions - the addition of larger inclusions gives the mixture texture.

Important! When buying plaster of any kind, it is important to pay attention to its compliance with GOSTs and international requirements. These are the main signs of high quality and reliability of the material.
Facade finished with mineral plaster
Mineral plaster, in turn, is divided into several types. First, it is worth dividing all its variety of forms into two types - decorative and facade.
Fortunately, they are not very different from each other. Is that the facade plaster, that is, the one that is used outside the house, must necessarily withstand the effects of various natural factors. In this case, it is usually the brands that include large fractions of filler that are usually of the facade type. For example, stone plaster can be used to make the walls embossed. Also, additives that increase resistance to ultraviolet radiation are necessarily introduced into facade plasters.
Application of mineral facade plaster
Note! The consumption of facade mineral plaster is always quite high, since it is usually applied with a layer of at least 5 mm.
In general, both facade and decorative mineral plasters, in addition to protecting the surface and leveling it, give it a beautiful appearance and a certain texture. The latter will depend on the type of filler.
Table. Types of fillers for plaster.
|Glass|| Contrary to fears, such walls will not be scratched, since glass inclusions do not have sharp edges. But they look very impressive.
|Clay|| One of the cheapest options, but it is possible to easily choose plaster by color, since the variety of color variations is quite large. Often used for indoor interior design.
|Ceramics|| Quite a rare type of filler, since the process of making such plasters is considered rather complicated.
But from their use, you can get a rather interesting effect.
|Anthracite|| Waste from coal production allows you to create plaster of a dark shade, but it is difficult to purchase this option - it rarely hits the shelves.
|Quartz|| A fairly common type of filler. Cheap and affordable, but it looks really nice with its addition. In addition, the mixture is easy to apply.
|Marble|| The coating is very durable and looks like a natural stone. Often used not only for facade, but also for interior work.It is difficult to apply marble plaster.
|Mica|| Such plaster is also called terrazite. Due to the peculiarities of the filler, the walls will look very interesting - they will shine gently.
The final result when applying mineral plaster is also strongly influenced by the size of the filler fractions - for example, the following types of compositions are distinguished:

For facades, you can use the types of plasters belonging to the range from coarse to medium texture ... However, sometimes more "gentle" options are acquired.
How to choose facade plaster
Mineral facade plasters have , like any other material, it has its pros and cons, which are associated with the application technology and operation features.
Advantages of mineral plasters:

Another example of using decorative facade plaster
Working with mineral plasters can only be done manually. So labor costs in the process of applying the material to the walls will be great.
Facade plaster for aerated concrete
In terms of technical characteristics, aerated concrete differs markedly from other materials, and these differences must be taken into account when choosing an exterior finish for walls.
Plastering is considered the most popular option, and in order for the coating to match the base material as much as possible, you need to choose the right composition.
The scope of facade mineral plasters is not limited only to the walls of a residential building. Since the plasters have excellent strength characteristics, they are also used in other places, for example, in industrial buildings, cafes, restaurants, cultural institutions, train stations, underground passages and so on. They perfectly withstand almost critical operating conditions. Mineral plaster is often used to decorate the basements of buildings and staircases.
Application of decorative mineral plaster
Note! It is impractical to use mineral plasters for rough work. Usually they are applied to an already prepared and leveled wall surface. But such a material perfectly replaces tiles, wallpaper, and any other coatings both outside the house and inside.
Mineral plaster can also be used for finishing buildings located in large cities, since it is easy to clean. It is used in various climatic conditions, as it perfectly withstands changes in humidity and temperatures.
Another example of the use of such plaster
On sale there are a huge number of types of plaster mixes suitable for facade decoration. Let's get acquainted with how to apply one of the most popular plasters - "bark beetle", which contains granite chips with a grain size of up to 3 mm.
Decorative facade plaster with bark beetle texture
First, we will prepare all the necessary tools:
Important! It is worth preparing the plaster mixture immediately before application. And it is also important to breed it only strictly according to the instructions.
Step 1. First thing preparation of the treated surface is carried out. The wall must be flat and smooth - all irregularities are removed, pieces of cement mortar (if any) must be removed. It is better to grind all joints and seams with sandpaper.
Next, the walls are primed. The procedure can be carried out 30 minutes before starting work with plaster.
Application of the primer
Step 3. Prepare the plaster solution in accordance with the recommendations on the package. The mixture from the bag (strictly dosed) is poured into water and stirred with a construction mixer until a homogeneous consistency.
The dry mixture is poured into the bucket
Stirring the components
Step 4. The mixture is infused for about 10 minutes, after which its viscosity is checked with a spatula - the plaster in consistency should resemble thick sour cream.
Infusing the finished mixture
Step 5. Preliminary application of mineral plaster to the wall using plastic or metal grater. The excess is removed with an ordinary spatula.
The main task of the plasterer is to apply the mortar in an even layer.
Preliminary application of mineral plaster
Note! Do not immediately cover all the walls with plaster - it dries quickly, but you also need to apply a pattern. Therefore, the size of the area that can be covered with a solution at a time will depend on the speed of the plasterer and the speed of drying of the mixture. In the case of "Bark beetle" plaster, the drawing should be applied within half an hour after applying the solution to the walls.
Using a polyurethane float, the texture is formed. The grater is driven up or down along the already applied solution - this is how a decorative pattern appears. First, the float is carried out strictly along the wall from bottom to top, and next time - from top to bottom, next to (parallel) to the previously applied pattern.
Formation of the texture pattern
Step 7. After the plaster has dried, the wall can be painted or covered with special protective compositions.
You can give the walls of a country house a beautiful appearance, arrange a garage or a concrete fence with the help of facade mineral plaster with your own hands. The main thing is to follow the instructions and not rush to finish the work. Facade decoration is a painstaking business, and there is no need to rush.
