Options for decorative plaster inland walls. Color and texture. Outdoor activation technique for mineral wool, polystyrene foam or penplex

The facade finish is a very important process that determines appearance Buildings and its compliance environment. Several variants of facade plasters are isolated, which differ in composition, texture and type of binder. On the advantages, technology of application and the peculiarities of each of them will be talked further.

Benefits of facade plaster

Before moving to the advantages of the use of facade plaster, we will define the functional features of the facade finish:

• outdoor finish protects the building from negative atmospheric and mechanical impact;
• gives the building an attractive appearance and desired texture.

For tinting and adjusting the color of plaster, a dye is added to it. This finishing material is distinguished by a wide range of gamut.

Among the main advantages of the facade plaster, we note:

1. High adhesion with base, elasticity and high-quality composition.
2. The possibility of long-term storage, in non-divided form.
3. Resistance to mechanical effects, moisture, temperature regimens, ultraviolet radiation.
4. Environmental safety - material during operation does not emit toxic substances.
5. It is characterized by minimal absorbability of dirt, it is easy to clean. Some plaster options are self-cleaning.
6. Paropropusability - provides comfortable conditions for accommodation in the room. The coating passes air, creating natural ventilation.
7. The ease of application and a variety of plastered options for texture, composition, color, method of applying.

In the ratio of the compositions of plasters, options are allocated:

• mineral;
• silicate;
• acrylic;
• silicone origin.

The first option consists of cement with the addition of polymer inclusions, which improve the adhesion and give the composition of greater elasticity. Silicate plaster mass contains fiberglass inclusions and plasticizers, has good performance characteristics.

Plaster by acrylic basis Contains an acrylic resin, and silicone - silicone. If the wall is made of natural materialThe plastering formulations of mineral, silicate or silicone origin are used for its finishes. These compositions have high vapor permeability, well interact with insulation in the form of mineral wool. For polystyrene insulation systems, options for plastering on an acrylic basis are suitable.

Outdoor plaster for the facade on an acrylic basis is characterized by good characteristics and the greatest service life. Mineral plaster is the cheapest, but also in operation - the least durable. Average resistance to exposure external environment The plaster with silicate and silicone makeup is different.

The structure of plaster also determines the duration of its operation. The greater the surface differs, the faster it is covered by cracks. Therefore, we recommend to give preference to rough surfaces.

Stucco resistance Before burning is directly determined by the saturation of the tones. The lighter tone of plaster, the better it retains the color indicators.

Types of facade plaster and their characteristics

Read more with the main types of plaster for outdoor decoration Buildings. First of all, consider the main types of plasters in the ratio with the composition.

Stucco with acrylic binders - is distinguished by good parpropusk abilities. This composition, with a lack of moisture in the room, gives it, and with an excess - absorbs, thereby maintaining optimal microclumatic conditions. This is ensured by the presence of a resin dispersion on a synthetic basis. Among the additional advantages of this composition, we note: good resistance to temperature fluctuations, elasticity, resistance to microorganisms: fungus and mold.

Despite this, acrylic plaster has certain disadvantages, namely:

• it is easily contaminated, as it does not have electrostaticity;
• differs high cost.

The facade plaster of silicate origin also has high record permeability. This coating is distinguished by a wide range of applications, as it has neutral electric static. The main element of this plaster is a potassium-based liquid glass. The coating is not prone to pollution, it is well tolerated by moisture, fluctuations in temperature, ultraviolet radiation is not cracking.

Mineral plaster - one of the most popular finishing materials consists of cement with additional polymeric substances. The material is characterized by the highest strength characteristics available to the cost and wide range of use. In addition, we note the following advantages of mineral-based plaster:

• high level of vapor permeability - no condensate on the walls, adjust the microclumatic conditions indoors;
• high pH provides stucco resistance before the advent of fungus and mold;
• frost resistance, resistance to precipitation and ultraviolet radiation;
• fire safety - the material is not inclined to burning;
• environmental safety - in the composition of plaster does not have toxic substances, harmful to health;
• ease of washing - Conventional water or additional detergents are used to clean the walls;
• after drying, it is not amenable to shrinkage and does not crack, subject to the technology of applying plaster on the wall.

However, mineral plaster is characterized by a limited color scheme, although after drying, it is painted with facade paints in almost any color. The process of applying plaster requires compliance with strict technological standards and dosages, otherwise the coating will not have the necessary strength.

The duration of the coating operation is about ten years, the material is characterized by sensitivity to vibrations, under their influence cracks.

Silicone plaster is distinguished by maximum durability, good dirt-repellent abilities and resistance to atmospheric precipitation. The walls on which this finishing material is applied is not inclined to form mold or fungus. Silicone Plaster - Universal Composition, which combined all the advantages of plasters on mineral and acrylic basis:

• excellent moisture-repellent abilities;
• good vapor-permeable characteristics;
• resistance to fungus, mold and other microorganisms;
• increased level of resistance to temperature fluctuations;
• the absence of not only cracks, but also microcracks on the facade part of the building;
• high level of elasticity;
• high-strength adhesion with any of the coatings.

Several textural options silicone plaster:

• coroede - is used to finish the facade, insulated by foam, additionally reinforced with a glasswork;
• lamb - different roughness;
• stone-type plaster - is distinguished by a smoother texture and a stone is added to it as a filler;
• plastering on a Venetian-based basis - contains a marble crumb, in appearance is similar to polished marble coating.

Mineral Type Facade Plaster Mounting Technology

Before the start of applying mineral plaster - align the base. If necessary, remove the old finish, get rid of cracks and other surface defects. Remove bold spots and rust. Next, the surface is covered with a primer on an acrylic basis, this composition has a powerful antiseptic effect and improves the clutch of the wall with further finishing material.

At the next stage, a plaster mortar is prepared. Preview the instructions in which the preparation recommendations are indicated. Two ways of applying plaster are distinguished:

• manual;
• mechanical.

The first implies the use of a metal spatula, and the second is based on the use of special pumping equipment. The optimal air temperature for this kind of work is from +12 to +24 degrees.

Mixed mixing equipment greatly simplifies the process of applying plaster, evenly distributing it on the surface. For use, follow the instructions below:

1. Prepare a tool to work, take a gun in your hands and turn sideways to the wall.
2. Install the pump into the container with the plastering solution. Open the valve, and wait for plaster on the wall.
3. Apply the composition at first upwards, and then right left. First fill in small irregularities and depressions.
4. Upon completion of work, close the valve, then using the rule to split the surface.

Manual application of plaster is a more complex process, since the solution is applied to the surface with a spatula. At the same time, it is important to choose the optimal thickness of the layer. After applying the solution, wait half an hour to grasp it. Next follows the process of manufacturing texture of plaster using a special grater.

Use decorative plaster from one manufacturer and preferably one batch. Perform work with the use of protective equipment in the form of gloves, safety glasses. After applying plaster, at least three days, protect it from excessive solar radiation, wind and moisture.

Application of facade silicone type plaster

At the initial stage of working with silicone facade plaster with their own hands, carefully prepare the surface. In the presence of seams between the masonry material, they are sewn to a minimum to one centimeter. To improve the clutch with the surface, the facade decreases the seams of a deformation character. Next, the surface is dustd and moistened.

At the next stage, a plaster mixture is prepared, the optimal time to use the plaster mortar is 1-2 hours. Next, the composition loses the strength characteristics.

Next follows the process of applying plaster spray. For these purposes, you will need to have a tool for installing facade plaster and certain skills to work with it. Throwing should be sharp and strong, so that the solution is good adhesive to the surface.

• it is forbidden to apply plaster on recently constructed walls, since when shrinking there is a risk of her cracking;
• the gypsum solution is not applied to the concrete base, since in the future such plaster will swell and fall off, first the wall is separated by plaster with the content of lime, and then with a plaster;
• stouting plaster is performed a few days after it is applied, the plaster becomes tough, but not completely captured;
• the thickness of one layer of plaster composition should not exceed two centimeters.

Use a special grater from a tree or aluminum to grout and aluminum, on top of which foam plastic is pasted. Circular movements pierce it to the surface, pushing it with a solution.

Features of the facade coating acrylic type

An ordinary spatula is used to apply on an acrylic basis. This plaster is characterized by the highest drying rate. Therefore, before applying the composition, it is recommended to align the surface as much as possible. The processing of the selected fragment is performed quickly and continuously. Otherwise, there is a chance of the appearance of joints, irregularities and differences in color.

Pre-divide the wall into several sections, to which the plastering solution is stucked. If necessary during the break, before applying plaster, moisten the boundaries of the previous section with water.

A variant of applying acrylic plaster using special equipment in the form of a spraying machine. Up to the complete drying of the composition, protect it from atmospheric precipitation.

Please note that the color of the dry acrylic plaster is always darker than liquid. Therefore, the facade with time after drying it darkens. For the maximum long period of operation of acrylic plaster, apply it to a pre-prepared surface.

Clean the facade from the old plaster or paint, get rid of fat or corrosion stains, drive the surface. The thickness of the applied layer should not exceed three millimeters. The time of setting the composition is 25 minutes, and complete drying from 10 hours. Special rollers use special rollers to impart the walls. For washing acrylic plaster enough use warm water with a sponge.

Facade plaster video

Decorative facade plaster not only creates a visually attractive view of the house, but also increases its operational properties.

Facade decorative finish has many advantages. Consider its characteristics in more detail.

Features of decorative plaster

Its main difference is to create a beautiful design of the building and protect it from the external influences of nature leading to destruction.

Decorative plasters for external work possess the following qualities:

1. Waterproof. The material does not change under the influence of moisture and repels or delays it.
2. Temperature resistance and resistance to climatic changes. High-quality facade plaster opposes direct sunlight and impact of atmospheric precipitation. Some of its species have special characteristics to apply it in the regions where temperature drops constantly.
3. Reliability. If the facade of the house is subjected to any mechanical effects, then for further normal depreciation of the buildings, the finishing base of the exterior walls has the ability to withstand them.
4. Parry permeability. The ability to skip the pair outward keeps the initial structure of the building.
5. Increasing the heat and sound insulation of the building. Decorative facade plaster increases the thermal insulation of the house, due to which you can significantly save money for the payment of heating. It allows you to reduce the noise level.
6. Creating any texture and simplicity in applying a solution.

Types of facade plaster

Standard material has in its composition the basis and additional substances. The quality of finishing, price and appearance, as well as application technology will depend on their content.

Decorative facade plaster happens:

• mineral;
• acrylic;
• silicate;
• silicone.

Consider each of them in more detail.

1. Mineral finish

The most popular and economical finish. It is based on cement, which is complemented by special chemical substances that increase the resistance to moisture. The coating is solved quite enough, and over the years this indicator increases significantly.

But its operating time is quite low - only 10 years. It is unstable to cracks on the facade, and it is impossible to give color (mischieving the dye), if it is contained in the container.

Basically, all mixtures of this type have a poor color gamut.

To achieve an original shade, you need to apply additional staining, which increases the cost of the coating.

The mineral plaster of the outer walls is preparing strictly in the proportions indicated on the package, since the slightest deviation can lead to a deterioration in the properties of the coating.

1. Acrylic finish

Such a mixture perfectly transfers temperature changes and removes extra moisture. As a rule, facade decorative plaster Most people are compared with this substance. This is due to a wide range finishing materialwhich affects the general view and perception of the whole building.

The mixture does not require additional impurities, since it initially contains all the components you need. The life of the acrylic mixture of about 15-25 years.

The disadvantage is its pairs of resistance and instability to dust. Therefore, it is not necessary to apply on buildings that are located near the road, since the front plaster will quickly lose its brightness.

1. Silicate finish

The feature of the silicate composition is that it has high vapor permeability. The mixture consists of liquid glass and auxiliary additives, due to which it is simply applied to the surface and removes the extra liquid. Silicate composition is very resistant to pollution, which is particularly relevant for the buildings near the road.

This suspension is distinguished by its plasticity and economy. The life of its operation is about 20-25 years.

1. Silicone finish

Popular to use (today) Facade plaster. Parotypes and protects the building from any climatic influences. Pushes the dirt that retains its appearance for many years (service life before repair is about 20-25 years).

It does not disregard and a wide selection of colors that allow combining a few shades at the same time. The disadvantage of such a material is the high cost, which slightly reduces its popularity. But in this case the price justifies quality.

The Polish company Bolix produces all of the above four types of plaster. They have an average cost and high enough quality. Today, Bolix is \u200b\u200bquite popular and has proven itself in the building materials market.

Today with resources global Network It is possible to finish the facade with decorative plaster with their own hands, which will save money.

An alternative option can be attracted to the work of specialists. This will contribute to high-quality work and reducing the spent time.

Stucco, do it yourself

Specialized equipment is not required to apply finishing material. It is enough to have in its arsenal tools a standard set for plastering.

To create a finish of the house, you need to perform work in the following sequence:

1. Preparatory work. Check the availability of irregularities (no more than 15 mm is allowed). If they are, you need to apply special leveling mixtures. It will be much easier to perform these works if the house has already been finishing material. Its enough to carefully remove and clean the surface for subsequent finishes.
2. Protecting the surface. To increase the adhesion of materials, it is necessary to apply special primer materials.
3. Preparation of a solution for plastering. Depending on the type of plaster, you need to prepare it for work. If this mineral mixture is to dilute it in the desired proportions indicated on the package. Silicone composition can be simply mixed.
4. Plastering. The first layer must be applied exactly and with particular accuracy, as follow-ups depend on it. It should be borne in mind that one layer of finishing should not exceed 40 mm. The next layer is allowed only after drying the previous one.
5. Pushing the surface. These works must be conducted on a semi-dry surface. To create an unusual coating structure, rollers use various configurations.

The main point is the air temperature when performing work.

Watching can be called the oldest and at the same time the most common way. Plaster is a versatile material that is able to make a complete type of building, and remove visible irregularities or hide the errors arising over time. In addition to creating an aesthetic type of building, this type of facing also has some useful properties.

Benefits

1. Creating a smooth and smooth surface is the main advantage of any type of plaster. It is she who can hide all the shortcomings of the building shortcomings or the error of the material from which the walls are made.
2. Protection of walls from moisture penetration. Creates protective barrierwhich prevents the destruction of the walls of moisture and dampness. At the same time, the layer of plastering is often vapor permeable, which allows the walls to breathe.

"Coroed" - one of the plaster loved by many

1. Allows you to work on various surfaces (brick, concrete). In some cases, the plaster is subject to walls insulated by foam or mineral wool.
2. Many types of plasters allow you to create textured surfaces, carrying out all kinds of designers and, satisfying the desires of many customers.

Main species

There is a huge number of types of plaster. All of them divide depending on which finishing works are used and what materials are included in their composition.

So, all plaster mixes are divided into ordinary, decorative and special.

Normal

Finishing mixtures of this group are used to align basic surfaces and prepare them for further work. They are applied to brick, concrete, slag block walls and are protected from all kinds of atmospheric phenomena.

Such mixtures in the future can be applied putty, varnish or paint.

• Gypsum. Gypsum plaster is used for outdoor work quite rarely. Most often, this type of finish is used to pre-align the various surfaces, as well as to prepare the base for subsequent decorative design.

This species is characterized by a high degree of adhesion with almost any surfaces. It has less thermal conductivity. When operating, dried plaster is not susceptible to cracking.

Tip! Buying this plaster mix, it is worth considering the fact that in this case the price determines the quality of the material. Therefore, by choosing a cheaper mixture - there is a risk of acquiring a low quality product.

At all positive moments gypsum plaster It is impossible not to say that it is often used for interior decoration premises. It is a high degree of exposure to weather conditions that makes it not practical for external design.

• Cement-sand. Perhaps the most common, both for external and for internal work. In construction, such material will be applied for quite some time, and during this time has acquired many adherents.

The main ingredients of the plaster mixture cement and sand in a certain proportion.

The main advantage of such plaster is high strength and versatility. It is often used when aligning brick and slag block walls.

Cement-sand plaster is quite moisture and frost-resistant, which makes it indispensable when construction work in houses and exterior decoration of apartments. In addition, it is not difficult to cook and apply such a finish.

Decorative

Decorative or texture plaster for external work is usually used at the final finish stage. After it is applied, the walls acquire a complete appearance.

This type of plaster is characterized by color gamut, relief and texture.

• Mineral.

Pretty common view facade finish. Acceptable price allows you to choose this type of plaster at much more often. The main ingredients of the plastering are minerals And various additives that allow it to apply it to most types of surfaces.

The most popular representative of mineral decorative plaster is a croroede (photo). Most often it is used to design facades of houses, less often with interior finishing works.

• Coroede.

This type of finishes received its name due to the effect, which is created when applied and resembles a cutting of a tree damaged by the vertoon beetle.

Coroed has nearby positive momentsThanks to which it became the most popular material. The main advantage is that it has high strength. This allows not to change its structure and appearance under various weather conditions (aggressive sun, an increased level of humidity, sharp differences of temperature).

Plastering mixture of coroede can be prepared and applied without the help of specialists. It is enough to adhere to all the recommendations that the instruction offers. Also, this coating is not prone to resolve and cracking.

It should also be noted that the plaster of the croroede is applied for external work on any surfaces.

Tip! For the best adhesion, the basis must be necessary to process the soil mixture.

• Acrylic.

This type of plaster is different long time operation (up to 25 years). Among the components of such mixtures, acrylic resins play the main role, allowing to hide even the smallest cracks.

And due to the fact that it is rather plastic and can slightly stretch - shrinkage and cracking is not terrible. This type is able to maintain its original appearance for a long time.

However, it is impossible not to say about the minuses of such a finish. Since this textured plaster for external work is a steamproof, most experts recommend to apply it only to foam. In addition, she pretty strongly attracts dust, which can affect its original color.

• Silicate.

Like the previous view, this finish also has a long service life. The main substance that is part of this type of plaster, potassium liquid glass, which gives the strength to the final coating.

The main advantage of such plasters is parpropuscular ability. Therefore, these mixtures are used when the facades of basalt wool are insulation.

Also silicate plasters due to the plasticity are not subjected to cracking. In addition, this type of finish has antistatic properties that contribute to the repulsion of dust. Due to this, the appearance of facades remains unchanged for a long time.

• Silicone.

Of all the above silicone plaster mixture, the most expensive. The service life of such a finish is more than 25 years. It is manufactured on the basis of silicone. Packaged in buckets, it is usually ready for use.

This type of plaster usually applies when repair work, held in old buildings, due to its ability to apply to any type of base. In addition, it has the greatest degree of elasticity and is not subject to cracking.

The effect of self-cleaning and rich color range allows the use of silicone plaster for finishing houses that are located in various zones, starting with industrial.

Among the disadvantages of this material is the need for its use solely with the construction mixtures of the silicone group.

• Polymer. This type of finish is quite new on the market. building materials And used exclusively in decorative purposes. Polymer plaster for external work is used to finish facades of buildings, as well as the ground.

A thin layer applied, it provides impact resistance and frost resistance to the walls. And water resistance helps to prevent even the leakage of excessive dampness into the room.

Special

Special plaster mixes are a finish that is selected depending on the necessary effect. They are used as additional protection against moisture, noise, frost. Also, such a finish can be used as a basis for decorative plaster.

Among all species special plasters Select the following:

• Waterproof;
• Sound insulation;
• X-ray-protective.

However, it is worth noting that the frost-resistant plaster for external work is particularly popular in view of its relevance. Moreover, except for protection from cold in the winter season, it has both insulating properties, preventing the heating of the building and in hot months.

Summary

We dismantled the most popular types of plastering mixtures for outdoor work. Now you can easily decide which exactly choose. And the video in this article will show visual information on the agreed topic, see!

The modern market offers a rather diverse selection of materials for outdoor work. One of the oldest and proven finishes is plaster.

Usually this building mixture consists of a binder component and any filler (gypsum, cement, sand or lime). Depending on the composition allocate different types Facade plasters.

All of them can be used for the finishing coverage of the outdoor walls of the building. For the application of facade plaster requires pre-processing of the facade of the primer, grout and putty.

Benefits of facing plaster

1. Watching does not miss steam and moisture, protecting the facade of water. The walls "breathe", as in attachment facades, by preserving the main principle - increase the moisture permeability of the material from the inner wall to the outer.
2. With the help of facade finishing materials, it is not only a smooth, but also embossed facing. A wide range of textures allows you to implement original design ideas.
3. It is possible to apply mixtures for external work not only on brick or stone walls, but also on the insulated foam or mineral wool facade.
4. Facade plaster allows you to change the color of the house with minimal cost time, forces and financial resources. For comparison: To change the color of the house, lined with siding, you will have to dismantle siding and install a new one.

Types of plastecocks

Building materials manufacturers offer four types of finishing mixes for the facade:

• mineral;
• acrylic;
• silicate;
• silicone.

These plaster mixes differ not only by the components and properties, but also the features of application.

Mineral Plaster

The basis of this category of the facade mixture is ordinary portland cement, due to which it is the most durable type of coating.

It is sold in bags and today is the cheapest. Its importantly, its dignity is the infertility of the appearance of fungi and mold, which is explained by the properties of components included in its composition.

The disadvantage is the small color scheme. But this can be corrected due to silicate paint, which is applied on top of this type of plaster. Silicate paint can be any shade, it deeply penetrates the mineral mixture, strengthening it, reduces moisture permeability.

Facade plaster based on minerals is the simplest in applying.

If after docking there are distinctions, they are easy to paint, and then they are practically invisible. That is why mineral mixtures "Cameshkovaya" and "Coroed" are most popular for finishing facades.

Acrylic plaster

The properties of this finishing material directly depend on the composition of the mixture itself, which is water solution Acrylic, which radically distinguishes it from other types of plaster.

It is quite plastic and resistant to the temperature differences material for outdoor work. The only drawback of acrylic plaster is neutral electrostaticity: the material attracts dirt and dust.

However, due to the low absorption acrylic, the dirt is not absorbed and is easily washed off with water. The best way The care of such a coating is rain or water jet.

Another difficulty associated with the acrylic-based finish is the order of its application. The fact is that Acrylic dries quickly, and if you dreamed halfway, and return to work in time, then a noticeable difference in the joint will be found in the joint zone.

Therefore, apply acrylic mixtures preferably planes and take a break, only when moving to another wall of the facade. With the help of various kernels you can give any color.

Do it better with the help of computer equipment, because with manual staining in different buckets It may turn out a different shade. A acrylic mixture is sold in ready-to-applying form.

As positive moments, you can allocate:

• high steaming ability due to which the walls covered with acrylic give excess moisture, and interior not moisturized at the expense of the steam accumulating in them;
• elasticity and resistance to temperature differences;
• low absorption - the accumulated dirt and dust is easily removed by water;
• protected from microorganisms due to biocidal supplements;
• the solution is produced ready for use and already contains all the necessary additives;
• a wide range of decorative options: "lakes", "Coroed" and so on.

Silicate plaster

This type of plaster includes mineral components. The difference lies in the binder element, which is liquid potassium glass.

It is the composition that the high moisturefrost ability and low elasticity is explained, due to which this type of facing coating can be used on difficult surfaces, like a cellular concrete.

Essential plus silicate plaster For external work lies in the fact that it does not attract dirt or dust at all.

So the issue of care for it is removed automatically during operation. Like acrylic, it is produced in the finished use of the form and has an innumerable amount of various shades.

As a minus, the appearance of microcracks on the plastered surface can be called, so the facade plaster based on liquid glass is most suitable for facing the facades from the shell. Often the same composition covers walls from aerated concrete and foam concrete. The reason for choosing consists in high vapor permeability of this material.

Silicone plaster

This is the most expensive kind of facade coating of decorative plasters for outdoor work. After all, due to the silicone basis, the smallest particles of the filler can be added to it.

For example, with the help of quartz sand added to the silicone plaster on the outer walls, you can create a natural stone effect.

As the main advantages of silicone plaster allocate:

• a wide range of color palette (white silicone plaster is easily kernel with painting pigments);
• self-cleaning (silicone compounds are easily cleaned from dust with rain and wind, so the facade will not have to be washed during operation);
• elasticity (silicone plasticity exceeds even acrylic mixtures);
• parry permeability (as a result of this quality, the plastered walls "breathe").

Manufacturers

Selecting decorative plaster, it is necessary to pay attention not only to the properties, composition and view of the mixture itself, but also on the manufacturer's company.

Since the quality and product range often depends on the attitude towards it producers. Since usually decorative coating It is not suited, it is better to give preference to proven trademarks.

Among the manufacturers whose products are distinguished by high quality and invariably enjoy the respect of professionals, such companies can be distinguished as "Knauf", "Bolls", "Ceresit", "Chrysel".

It is these companies that produce universal products whose quality can be fully trusted.

Products of Bolls

Facade plaster "Bolls" is part of the extensive range of the Russian company producing construction mixes. Finishing materials "Bolls" on cement and plaster basis are used for exterior and internal works.

They are perfectly applied to concrete, brick and stone walls. The composition of some "Bolls" plaster is introduced sand for amplification plastic properties Or crumb from marble to strengthen the structure. Decorative mixtures "Bolls" are used to create original patterns on the outer walls. Depending on the composition, they are divided into plaster and cement.

Decorative plaster "Bolls" imitate marble or stone coating, create a radiance effect or wet silk - All this makes it possible to create original facing of any level of complexity.

For external works, the Bollox plaster is made from a mixture of sand, cement and polymer additives. Due to the composition, it hits well with the walls, does not crack from the drops of moisture and temperatures.

Bolls manufactures options for manual or machine application. Also there are frost-resistant varieties of plasters, suitable for applying under conditions of low temperatures.

Products of Knauf

Construction and finishing materials "Knauf" have been known to consumers and specialists for a long time. To date, little construction object costs without dry mixtures "Knauf". Initially, this company was known thanks to his gypsum MaterialsAnd today it also produces plaster mixes on a cement basis.

The range of cement compositions "KNAUF" is rather diverse. Thus, the rather popular "Knauf-Unterputz" plaster is used to finish the facades and internal works. A mixture of "KNAUF-ZOKELPUTTS" has increased strength, it is able to withstand high humidity.

The decorative plaster "Knauf-diamond" on a lime-cement basis is suitable for internal and external work. After applying and structuring, it can be painted.

Also, it is also impossible not to mention the plaster with polystyrene granules called "Knauf Grunband". The foam reduces the density of plaster compared to other mixtures and makes it a truly water repellent. It does not give a shrinkage, increases the thermal insulation of the wall and goes well on any surface.

The main purpose of the facade plaster is the finishing design of the walls of the building outside. This finish is available at a price, the coating is rather durable and has decorative properties. To sort out what plaster is better for the facade, consider it varieties and features.

There are 5 main types of this finishing material. All of them have their advantages and disadvantages, differ in the method of applying and specifications.

Features of facade plastecrockers

Plastering formulations for external work differ from coatings intended for operation indoors. They are present additional additives, enhancing strength, frost resistance, water-repellent properties and plasticity of the coating.

The facade cement-based plaster is made with the addition of high-strength its brands (M400 and higher). The proportions of the main operating components are also distinguished. So when preparing a solution for external work, the percentage of cement and sand will be 1: 3, and not 1: 4, as in the case of a mixture for interior decoration.

Primary requirements

Compositions for external work must comply with a number of requirements. Facade plaster can be considered as only if it is:

• moisture-resistant;
• resistant to temperature drops;
• strong enough to protect the facade from mechanical damage;
• vapor permeable;
• provides heat and sound insulation;
• it has decorative properties.

If you live near industrial facilities, the selected facade coating must have resistance to harmful radiation. The abundance of modern finishing compounds allows you to find plaster corresponding to all listed items.

Heat insulation

The layer of any facade plaster contributes to the preservation of heat inside the building. But if the walls are thin and may not provide due insulation, for the external finish, a composition with a special filler is needed.

The so-called "warm" plaster additionally contains polystyrene foam, perlite, vermiculite, foam glass or sawdust. Their addition significantly increases the thermal insulation characteristics of the walls - the 3-centimer layer of such plaster replaces 15 cm brick masonry.

Soundproofing

Plastering can also serve as a sound insulation material. This property is useful for those who live near the motorway, construction or other objects producing objects.

But with noise insulation, not any plaster mixture will cope. It should be present cement with pumice or slag or pumice and magnesite. Porous inclusions muffle the sound, partially absorbing it.

Of course, it is not worth counting on only the plaster, it is effective as auxiliary. With a high noise level, it is necessary to use additional sound insulation materials - foam plates, mineral wool.

Color and texture

Facade plaster not only protects the walls of the house, but also decorates them. With the help of such a finish, you can achieve an optimal combination of the facade with other elements of the building, pick the desired color and texture.

Stucco for exterior walls is available in a wide color palette. If you need to create a pronounced texture, a mixture is used with the addition of stone crumbs or ceramic granules.

Also, the surface of the plastered layer is treated with special graters, changing the cover of the coating. This method creates popular patterns, such as "Coroed", "lakes", etc.

What a decorative plaster is better for the facade - in each case it is solved individually. With it, you can create any patterns, right up to the simulation of brickwork and natural materials (Woods, stone).

Varieties

There are 5 types of facade plaster. They differ in the composition, properties and technology of application.

Mineral Plaster

Mineral plaster consists of hazed lime, M500 grade cement, and above, stone crumb, color clay or other small fillers. Additional additives that increase the resistance to mold and fungus may be present. Plaster is implemented as a dry mixture in bags, it is required to dissolve it with water.

They are applied by spatulas by manually either by a mechanized way. The finished solution is suitable for work for about 60-90 minutes. After drying, the coating forms a durable non-combustible layer with heat and sound insulation properties. Granules and supplements provide decorative decoration.

Depending on the characteristics of a particular product, mineral plaster retains its properties at temperatures up to -25 or even -50 degrees. The service life of the finish is about 15 years.

But it must be borne in mind that this type of coating poorly tolerates vibration. The use of mineral facade plaster is not recommended near railways, as well as in zones with seismic activity.

Acrylic plaster

In the acrylic facade plaster, acrylic resins are used instead of cement. In addition to them, there are:

• modifiers that increase strength, plasticity and other specifications;
• dyes responsible for the color of the coating;
• filler (sand, granules, stone crumb), creating a surface structure.

Acrylic plaster is sold in the form of a finished solution suitable for applying. The service life of such a coating is about 15-25 years. The plaster with the addition of acrylic is resistant to temperature drops, but easily attracts dirt. However, it is easy to clean, watering with water from the hose.

Before applying an acrylic coating from the surface of the walls, dust and residues of the previous finish are necessarily removed. If there are places affected by fungus and mold, they are previously treated with a special antiseptic.

Acrylic plaster grasps in 20 minutes, but it takes up to 48 hours to complete drying. At this time, the coating must be protected from direct sunlight from entering to avoid cracking. Because of the rapid frost, noticeable joints of the layers are often formed, so professional needs should be performed.

Silicone

Silicone facade plaster contains silicone resins, filler, coloring pigments and additives that increase the durability of the material. It is produced in the form of a finished solution.

Among the advantages of silicone coating, elevated moisture resistance, elasticity, self-cleaning ability, simplicity of application. The service life of such plaster - 20-25 years. The only drawback is a high price.

The solution is well seized on any, pre-purified from dust and dirt, surfaces. The technology of applying and drying conditions of silicone plaster is similar to recommendations for acrylic mixtures.

Silicate

Another expensive, but high-quality material is silicate plaster. It contains the same substances as in mineral, but there is one additional component - liquid glass.

Silicate plaster is realized as a solution. Just like silicone mixtures, it has antistatic properties, that is, repels dust. The finished coating has increased abrasion resistance, waterproofing and elasticity. Service life - 25 years and more.

Of the minuses of silicate plaster, it is necessary to note too fast frozen after applying. Because of this, only a professional who is able to perform work without errors from the first time can be engaged in plastering. In addition, silicate plaster requires the use of special primer.

Cement

Cement plaster - composition, tested by time. This inexpensive type of finishing material is used in Russia when lining inner and outer walls with decades. Its basis, as is clear from the name, - cement. It also includes lime or sand, there may be other additives that increase strength.

The mixture is sold in packaging in the form of a powder and divorced with water immediately before use. Cement plaster is different shades, but the color range is strongly limited. This problem can be solved by subsequent staining.

Obvious shortcomings cement plaster - the need to prepare a solution and low decorative qualities. Given the coverage and service life, on average it is 10 years.

Technology wet plaster

Probably, many have heard the term " wet stucco" Under it implies plastering over the multilayer "cake" from the primer, insulation and the reinforcing grid. Such a finish of the facade makes a point of dew beyond the limits of the house, taking on condensate. As a result, housing is obtained dry and warm, the optimal microclimate is created.

The thickness of the layers and their sequence may be different, but more often the order is as follows:

1. Base (wall).
2. Fixing primer.
3. Adhesive layer.
4. Thermal insulation material fixed by dowels.
5. Reinforcing layer.
6. Primer to improve adhesion.
7. Decorative plaster.

It is very important to choose the appropriate heat insulation material. What insulation is better for the facade under the stucco? A good option in this case - plates OSB., mineral wool or. They are moisture-resistant and reliably preserve heat.

Advantages and disadvantages of facade plaster

Facade plaster, like any method of finishing, has strengths and weaknesses. Various views differ significantly from each other, but you can still highlight the qualities common for this group of facing materials.

The advantages of plastering for external work include:

• fire resistance;
• thermal insulation properties;
• resistance to temperature differences;
• the ability to perform work without special equipment;
• small weight of the material;
• rapid production of decorative coating.

But there are disadvantages. Stickers stability to mechanical exposure lower than in ceramic panels, facing tiles and other similar materials.

If we are talking about decorative coverage, it will require professional skills. In addition, you can only perform work at temperatures above +5 degrees, and complete drying with a thick layer of plaster will take a lot of time.

How to choose?

The choice of facade plaster depends on the material of the walls of the task, the operating conditions of the coating and the requirements for it. Whether the composition with granules or with a smooth texture is a matter of taste. The same applies to color decoration.

If you think that the house requires additional warming, pay attention to the compositions containing perlite, vermiculite, foam glass, etc. Those who wish to repair the facade, suitable plaster with high strength - silicate or silicone.

Previous mix

In cases where it is necessary to perform work quickly, and the experience in this business is not enough, it is better to purchase ready-made compositions. With them, the risk of mistakes when mixing the solution is missing. There is a ready-made mixture and other advantages - convenient storage and transportation.

Selection of plaster for a specific surface

The answer to the question is what plaster will be better for the facade, directly depends on the material of the walls. Even high-quality plastering composition may not justify hopes when applied to an inappropriate basis.

Optimal combination of types of facade plaster and base material:

• Brick walls - cement or silicone mixture.
• Aerated concrete - silicate or silicone composition.
• Wooden walls - silicate plaster.
• The insulation plates - the composition based on acrylic, applied over the reinforcing mesh.
• Other options are a silicate mixture.

Facing with decorative plaster is a modern, inexpensive and reliable way to design the facade of the house. When complying with the technology of applying and compliance with the material of the base composition of the mixture, you will definitely get a solid and decorative coating. If you plan to create a complex pattern, but there are no necessary skills, it is worth contacting professional builders.
