Exterior wall plastering: types, preparation, finishing of brick and concrete surfaces. How to plaster brick walls correctly: the choice of material, technology and nuances The better it is to plaster a house outside

Properly carried out external plastering of the house allows not only to ennoble the facade, but also significantly improve its performance.

It is not surprising that, despite all the innovations that have appeared in the field of cladding buildings from the outside, many prefer plastering.

Advantages of plaster

Regardless of the chosen type of cladding for the house, plaster has a number of advantages:

• democratic cost (price is perhaps one of the main factors explaining why so many people who want to ennoble their cottage or Vacation home, prefer to plaster);
• aesthetic appearance (if you plaster the facade correctly, it will look very attractive, because a wide range of textures and shades of modern decorative plasters allows you to give the facade any look);
• water permeability (covering the house with a plaster mixture protects the facade and insulation from moisture and precipitation);
• resistance to external influences (anti-corrosion and frost-resistant qualities);
• simplicity and ease of use (in order to properly and efficiently plaster a house, you just need to know the correct sequence of actions and have a minimum set of tools);
• dozens of shades and textures.

Textured plaster

Textured plaster mixtures are obtained when granular granules of various diameters are introduced into the solution. It can be marble or granite chips, linen, wood fibers, quartz.

If you plaster the facade with these solutions, you get a unique look: granular inclusions create an original relief.

Thanks to the heterogeneous texture, you can easily hide small defects in the walls of the house from the outside (various recesses and protrusions) organically fit into the overall picture, complementing the texture in its own way.

Another plus of textured mixtures is the ability to paint the plastered facade in any color. To do this, it is enough to add a dye to the solution before plastering the house outside, or to paint the walls after applying the plaster.

How to plaster the walls of the house

To properly plaster the house outside, you can use a special plastering machine, or you can apply the mortar with your own hands.

For independent application of plaster compositions, special equipment is not required, only a standard set of tools is needed. However, to create special textures, you need curly spatulas and, of course, some experience in this area. However, with a little training, you can easily learn how to plaster facades correctly.

The main thing is to strictly follow the manufacturer's recommendations on the use of plaster, its application and drying time. In case of any doubts about one's abilities and capabilities to make the cladding with plaster correctly and efficiently, it is better to seek the help of qualified workers.

Preparing for plastering

To plaster the house outside correctly and without a hitch, before you start facing work, you should prepare the facade.

The main thing is to prepare the wall itself for applying plaster: remove the remnants of the previous finish, clean the surface, get rid of dust and dirt.

By using special means you should degrease the surface and remove the fungus and mold, if any. After preparatory work priming is carried out.

In order not to waste expensive facade plaster, it is better to caulk all seams and defects with a special putty for the facade. If it is supposed to use relief plaster, then it is not necessary to level the wall.

Tool preparation

To properly plaster the facade, no special tools are needed. Everything you need can be bought at a regular building materials store: several spatulas of various types, a roller, a brush, a container for mortar and sandpaper.

The plaster can be applied to the walls with a sprayer, then the work will be done faster and easier.

To avoid skin irritation and contact with the solution in the eyes, carry out plastering work Better goggles and gloves. (To protect the instruments, it is better to wash off the solution from them immediately after use).

Plastering

It is better to plaster during the absence of wind, with a humidity of no more than 65% and at a temperature of five to twenty-five degrees Celsius.

At the first stage, “spraying” is carried out: it is necessary to throw the solution onto the wall with sharp movements. If there is a plastering machine, then it will be easier to do this, although more expensive. The first layer should not exceed 4 centimeters.

When the first layer dries, the second is applied. In the future, depending on the type of plaster mixture, grouting or shaping with rollers is carried out.

On final stage plaster is painted in the desired color. If the solution is already tinted, then there is no need to paint the walls.

The final stage

When the facade is plastered, it will be useful to stock up on a small amount of plaster of this color and texture for the future. So you can tint the places of defects that may arise as a result of the interaction of walls with any objects.

Caring for such a lining is quite simple: depending on the type of mixture used, you can wipe it with a dry or damp sponge, or blow it with compressed air.

Features of plastering a wooden house

Plaster for outdoor work is in excellent contact with any building materials: brick, concrete, drywall and wood.

Plastering a wooden facade is necessary to seal the gaps between the boards, prevent them from drying out and the appearance of mold and fungus.

You can not plaster wooden house immediately after construction, because the house must stand and sag.

If you start plastering immediately, then in a couple of years the lining will become unusable.

Plastering wooden house can be carried out with any solution for outdoor use. The main thing is to decide for what purpose it will be applied: how self-finishing or with subsequent painting.

Mineral and acrylic solutions are well suited for self-cladding. Mosaic solutions with quartz grain or marble chips help to change the appearance of the facade, visually ennoble it.

In order for mineral plaster to adhere well to wooden facade and protected it from external influences, plasticizing components are added to the mixture.

Perfect finish for wooden walls country house there will be acrylic plaster, which has excellent adhesion to the treated surface and retains natural air exchange, allowing the walls to "breathe".

A wide range of colors of acrylic mixtures allows you to embody any architectural idea and change the facade beyond recognition.

Modern facing materials for a wooden house perfectly protect it from negative influences environment, from mold, cracking, which significantly extends the life of the facade and the building itself.

Conclusion

Plastering is far from the easiest way outdoor processing facades, but it has a lot of advantages over other building materials.

The abundance of colors and textures, as well as the relative low cost, in comparison with other types of cladding, allows you to give your home a unique and original look which will make it stand out from the rest of the buildings.

Plastering the walls of a house from the outside is a simple, easy, and cheap process, however, like any business, the ode has its own nuances and "pitfalls" that are dangerous for beginners. What is it about?

To save money and time associated with redoing or restoring plaster, you must clearly understand some of the main actions that will negatively affect the quality of the plaster:

The plaster should not be applied in several layers (that is, the layer is dry, you applied the next one) - it will have poor strength, and then, due to the uneven drying of the layers, cracks form in the joints on the walls, which will lead to subsequent repairs.

It is strictly forbidden to apply plaster on walls that have not been treated with impregnations - this can lead to peeling of the plaster. This is especially common for concrete walls.

It is forbidden to plaster the walls when the ambient temperature is extremely high, for example, over 30 ºС. The erroneous opinion is that if the plaster dries quickly, then it is of high quality. Drying of the plaster should take place at 15 ºС, when no direct Sun rays. Compliance with these standards will allow you to get plaster that does not have cracks, stains and other “cutting eyes” blunders.

If a brick wall is being plastered, then the seams must be deepened. You must clean the seams with any metal tool. This is done so that additional heat losses do not occur and adhesion increases.

Work should not stop for longer than 1-2 hours. If you do not follow this rule, then the wall will have characteristic spots that do not betray the building of a pleasant appearance.

Plaster mortar for outdoor work must be well mixed, and have a uniform consistency, the application of plaster with visible lumps or with unmixed impurities is prohibited.

Both the wall and the plaster must not be exposed to water, dust or dirt. Any of these impurities will help the plaster peel off faster. This is especially important for external plaster, which is subject to precipitation and temperature changes.

Proper facade plastering video:

In addition to the decorative purpose, according to all modern trends, plaster has a number of significant advantages:

• Prevents the ingress of moisture into the room, and does not prevent the penetration of air;
• The special composition gives the coating heat-insulating and noise-absorbing qualities;
• Wide choose textures allows you to give the coating a very different structure;
• Has the ability to implement visual changes in the future.

Plastering the exterior walls of the house will be a great way to make the structure brighter, more noticeable against the general background. Plaster mixtures are:

• silicate;
• Silicone;
• Mineral;
• Polymer;
• Self cooked.

In all these compositions, in addition to the main components, the content is allowed:

• Polymer particles that provide heat retention;
• A crumb of stone, for a visual effect;
• Glass sand will give shine;
• Small particles of crushed stone will help create an original texture.

How to plaster exterior walls? It is necessary to consider in more detail:

• Silicate solutions are ready for use immediately after hiding the original packaging. Such mixtures are not presented in the widest color scheme. Full use of the product is necessary, since it can no longer be stored after the container is opened. This type of plaster is a reliable barrier to moisture penetration, well withstands moderate mechanical loads;
• Silicone mixtures are also quite elastic, have good resistance to various atmospheric phenomena, and are prone to self-cleaning. The plaster coating has high performance characteristics. The disadvantages include a fairly high cost in comparison with other finishes;
• mineral mixtures. Cement is the main ingredient. Dry components require dilution with water according to the manufacturer's recipe. Plaster mixtures of this type are inexpensive, remarkably "breathe", they are easy to work with. The disadvantages include not very good elasticity, and high requirements for the surface, which will serve as the basis for the plaster layer.

If you are a beginner and do not know what is the best way to plaster the exterior walls of the house, use polymer plaster mixes. They are applicable to almost all substrates, resistant to temperature changes, create an attractive cladding that is different long term services.

Similar properties are made possible thanks to the artificial resins that make up the composition.

You can also do your own mixing. To do this, you need to take cement, fine sand and water, and then mix them in the proportions specified by the recipe. This is an affordable, but rather laborious way, which is very attractive for its financial availability.

It is important not only to know how to plaster exterior walls, but also on which surfaces the mortar will adhere well:

• stone surface;
• Wooden;
• Reinforced concrete;
• Monolithic concrete.

For concrete pavement a separate approach is needed. When choosing how to plaster the outer walls of the house, it is necessary to take into account the fact that the material both absorbs moisture and gives it back. It turns out that exterior finish should be softer than the main surface. Such measures will help prevent cracking, and the right product will not lead to evaporation and condensation.

The plastering of external walls from gas silicate blocks should occur differently than brick or concrete surfaces. It is unacceptable that the plastering of the outer walls of the blocks is carried out cement-sand mortar, since in this case it is not necessary to allow a violation of vapor permeability and the internal climate in the house.

Plastering of exterior walls made of aerated concrete is carried out using special light plaster mixes. One of the best options is a mixture of lime, sand, a small proportion of cement.

And if the outer walls are made of gypsum, how to plaster? For such a foundation, gypsum will be the most the best option. You can also use gypsum mixtures with the addition of lime. cement mixtures are not suitable for these purposes, since chemical incompatibility is formed.

Do-it-yourself plastering of external walls requires careful surface preparation. This stage is very important, since the final result will depend on it and further terms surface operation. The process includes:

• Removal of the old layer of plaster material;
• Inspection and verification of the base for integrity, strength;
• Removal of visible contaminants in the form of dust, oily stains. Creating a dry and clean surface will ensure good adhesion to the applied product;
• When working with brick wall you will need an additional increase in joints and the creation of holes that will improve adhesion;
• The next step is to treat the surface with a primer. The product can be applied with a brush or roller. Give preference to deep penetration formulations;
• Now you need to mount the paint grid on the wall, and remove all the irregularities and cracks found with putty. The use of a reliable and proven method is also welcome - installing beacons. Observing with accuracy all the rules for their installation, you can get a perfectly flat surface.

The technology of plastering external walls includes enough simple steps. If you have some experience repair work- you can do everything yourself.

To plaster outer wall at home, you need to learn certain steps:

• splashing. To perform this stage of work, it will be necessary to prepare a liquid solution into which liquid PVA glue is added. The resulting composition is sprayed onto the surface using a small bucket capacity. The process must be done in a measured manner. The more roughness is formed on the wall, the better the whole material will hold. Before continuing work, you need to wait for it to dry;
• Application of the base layer. The finished composition should be like thick sour cream. The application takes place by applying between the beacons. The layer should not exceed 5 mm. Having attached the rule with the narrow side to the lighthouses, move it from side to side, and then smoothly heading up;
• The finished composition should be like thick sour cream. The application takes place by applying between the beacons. The layer should not exceed 5 mm. Having attached the rule with the narrow side to the lighthouses, move it from side to side, and then smoothly heading up;
• For the final grouting of the coating, it is necessary to use a special grater, which will help in smoothing out small cracks. We move in a spiral from a small circle to a large one;
• Drying also needs a certain amount of time. It will take about 5 days to set;
• The plaster, which gives the wall texture, is not applied in a continuous layer of mortar, but at small intervals. They are closed by stretching the solution when it begins to dry out.

For those who decide to learn all the information on how to plaster a wall on the street with their own hands, you need to learn how the material is applied to the basement and corners of the building.

The basement refers to special areas of the house that need special protection. That is why it is covered only with moisture-resistant cement-based compounds. Also, at the turn of the wall and the basement, installation will be required waterproofing materials. If this area is solid, then it is plastered with a wall, which is not typical for a speaker.

Work on the corners is left for later. To finish them, you need to use polymer types decorative plaster, which is characterized by a high degree of resistance to mechanical stress.

No one will argue that exterior wall plastering is important during construction. The materials used for this do not always provide a quality result if important requirements and technologies have not been met.

For those who are so interested in the question: how to plaster the outer wall with your own hands, you should follow a number of rules:

• On a newly built house, the process of applying plaster becomes possible after a couple of months. Ideally, if this period is extended to six months. Otherwise, as a result of shrinkage of the building, cracks may appear;
• Plastering outside is carried out only after implementation internal works fully finished;
• Before plastering the outer wall of the house, it is important to complete all types of repairs - to carry out all communications, eliminate all holes, fill openings if necessary;
• It should be borne in mind that the base must always be stronger than the applied material. Do not allow reverse situations. Cement mixtures can be classified as durable plasters and lime-based materials as weak ones;
• Having chosen a specific plane for finishing, it is necessary to gradually complete the entire range of work without interrupting the finishing;
• Monitor the outside temperature during renovations. It should be moderate and not fall below 5 degrees Celsius. This is due to the fact that the plaster will not stick to the frozen wall as it should, but if it is too hot, it will simply slide off. If the air is still hot outside, spray the plaster with water to prevent cracking.

There are a number of the most popular types of plasters that are successfully used to create an original facade part: textured, cement-lime, thin synthetic. In composition, they have significant differences, but all are equally well suited for decorating walls.

The pebble structure can be attributed to the most popular finishing option. This plaster looks pretty, but also has good practicality. To obtain a certain result, the plaster layer can be processed almost immediately after finishing and after hardening.

The crumb can be both in the composition and on its surface using a special sprayer. After drying, the surface is fixed with adhesive, which contributes to good fixing and creating a surface resistant to damage.

Very original solution there will be an imitation wooden surface, spoiled by the bark beetle. To create this effect upper layer processed with a grater, which is held at a certain angle.

Colored cement-lime plaster looks very colorful. You can replace lime with marble dust, and then the effect will be simply amazing.

This option is not cheap. However, a complete surface decoration may not be performed. It is enough to select some important areas, and the rest, for example, to cover with pebbles.

Thin-layer plasters are very plastic, and allow thin plastering due to the reduction of layers. They are excellent in composition, suitable for use on the most various surfaces. Silicate plaster can also be classified as thin-layer. It is great for processing large areas of facade buildings.

After reading this article, you will know how to plaster exterior walls with your own hands. Let's do this process. The main thing is to follow the prescribed instructions. By following the recommendations, you will definitely achieve positive results, and beautiful facade your home will delight you for a long time.

How and with what to plaster the outer walls of the house with your own hands: video

Finishing product range external walls buildings and structures, quite extensive. Of course, buildings lined with newfangled materials look impressive. But the old fashioned way design - applying the solution - does not lose its popularity.

Before talking about the methodology for carrying out this work, it is worth understanding why the plaster does not go into oblivion?

• Firstly, all activities can be carried out in a short time. Many new facing materials cannot be attached directly to the surface - a supporting frame must be mounted under them. Plus - the features of the attachment. And this time and additional costs for materials.
• Secondly, working with some of them has many nuances, so quite often you cannot do without the services of professionals. At the same time, any person can do the external plastering of the walls on their own, if desired.
• Thirdly, this is practically the most economical way to embellish any building, and the easiest one, since you don’t have to set up a full-fledged construction site on the site and think about where and how to store materials. For reference. If you hire craftsmen, then their work will cost about 210 - 220 rubles / m2.
• Fourth, expediency. What is the point of spending money on expensive cladding for country house, garage, barn and a number of other similar buildings?

All buildings differ in the material from which the walls are built. Therefore, when preparing for external plastering of walls with your own hands, you should take into account the specifics of their decoration.

• Surface treatment of reinforced concrete products is carried out according to the following scheme: the primary layer of the solution (to ensure reliable adhesion) - priming - topcoat.
• A layer of small thickness (0.5 - 1 cm) is laid on the walls of aerated concrete, since this base does not absorb moisture well.
• For brick walls, such mixture components are used - cement, asbestos, sand. Since the base absorbs water well, the minimum layer thickness is 2 cm.
• If the solution is applied to the insulation material, then a reinforcing mesh is necessarily mounted.
• When finishing wood surfaces, shingles are used for such reinforcement.

The quality of the external plaster of the walls largely depends on the correct choice of this finishing material. There are several varieties of mixtures that differ in composition and, accordingly, properties. This must be taken into account based on local conditions.

Types of plasters

• Acrylic

The most convenient, as they are already ready for use, therefore, the mistakes often made during self-cooking solutions. The applied layer has good vapor permeability, so the likelihood of development of putrefactive processes is minimized. The elasticity of the composition allows you to "work" with surfaces of any configuration. Large selection of color tones.

• Silicone

They have higher quality than the previous ones, but their cost is quite high. Therefore, it is advisable to use only in certain cases.

• silicate

The basis - liquid glass(potassium). Sold ready for use. A feature of the product is the high vapor permeability of the hardened layer. Excellent for finishing surfaces made of cellular concrete.

• mineral

They are made on the basis of cement, therefore they are distinguished by increased strength. However, in terms of elasticity, they are inferior to their counterparts. The cost is the cheapest, and therefore most often used for self-plastering walls.

Step-by-step plastering technology

Let's consider the process from scratch, without going into the details of partial, "spot" plastering. Moreover, "general" operations that are carried out for any surface.

Preparation

Whoever thinks that it consists only in "cleaning-washing" makes a big mistake. Yes, you need all old finish remove and clean the wall. After that, it must be examined.

• All defects (slots, cracks, chips) are eliminated.
• It is desirable to level the wall as much as possible. This will slightly reduce the consumption of the mixture. But if it is smooth (concrete), then in order to ensure a reliable “coupling” of the primer, it is necessary to make notches or apply reinforcement over the entire surface.
• You need to understand that this stage- the only chance to extend the life of the base itself. After all, after applying the plaster layer, the wall will be completely closed. Therefore, depending on its material, surface treatment is performed. It is advisable to impregnate with antibacterial agents, for wood - also with fire retardants.
• Wall priming.

Installation of beacons

As a rule, purchased profiles are used. They are more comfortable to work with. In the direction from top to bottom, "ribbons" from the solution are laid, into which beacons are pressed. With the help of a plumb line and a rail, they are aligned in the vertical and horizontal planes.

Plastering

Produced between adjacent beacons, a wide strip from top to bottom. After applying the layer, it must be leveled. When it hardens a little, the beacons are removed and the voids are sealed with mortar.

Depending on the specifics of the structure of the layers, there may be several. But the “finish” is necessarily smoothed out, and after hardening it can be sanded. For him, when preparing the solution yourself, you need to use sand with fine fractions.

Helpful Hints

• Often, with independent external plastering of walls, the owners prefer to prepare the solution on their own. It should be noted that without much experience quality composition cannot be obtained. All proportions recommended in various sources are approximate. Much depends on the brand of cement, its shelf life (in 4-5 weeks it loses up to 40% of its properties), sand grain size and a number of other factors. Therefore, it is more expedient to purchase ready-made "pastes" or dry mixes.
• To save on plastering, you can buy cheap white mineral plaster, and then paint the wall with silicate paint of any color.
• When finishing brick surfaces, it is advisable to deepen the joints between the bricks. This will increase the reliability of the “coupling” of the plaster with the wall.

It should be noted that all work is carried out only at positive temperatures, in order to avoid water crystallization (formation of ice floes).

Now external plastering of walls is one of the most commonly used types of home decoration. Moisture, penetrating into the plastered walls, damages them and significantly worsens the thermal insulation. At the same time, the outer decorative trim can not only give the building a neat appearance, but also protect it bearing walls from destruction.

Advantages of plaster finish

In addition to ennobling the appearance, do-it-yourself outdoor plastering has a lot of other advantages:

• prevents the penetration of moisture inside, without retaining air;
• special components that make up the plaster mixture help to improve heat and sound insulation;
• a variety of textures for finishing houses on the outside allows you to give any structure to the outer layer facade plaster, as well as in the future to change not only the color, but also the texture itself.

What surfaces are suitable for plastering

The quality of work and the reliability of the coating directly depend on what material the facade of the house is made of. For applying plaster with your own hands are well suited:

• tree;
• stone;
• reinforced concrete slabs;
• monolithic concrete.

The sequence of work

The process of such wall decoration from the outside can be divided into 4 stages:

1. Selection of the necessary plaster mixture.
2. Surface preparation.
3. Installation of special beacons.
4. Plastering of the surface of the facade.

External plaster - its types

Most often, do-it-yourself external facade plastering of walls is performed using a special decorative composition. The mixture can be applied on the main layer or on the installed insulation. It can also be mixed with a variety of artificial or natural pigments to achieve the desired color or volumetric components in order to create a texture during application to the surface to be treated.

The color scheme of the exterior plaster

Before you determine which mixture is better to use in your work, you should know at least the basic physical properties certain types of solutions. Usually, some types of decorative mixtures are used during construction.

They are conditionally divided into:

• silicate;
• silicone;
• polymeric;
• mineral;
• and homemade mixes.

Differences in decorative mixtures

Silicate solutions are made liquid, that is, they can be used immediately after opening the container. But their main drawback is a small selection of colors. In addition, such mixtures must be consumed immediately, otherwise they will dry out quickly. Such facade plaster guarantees excellent waterproofing and is not afraid of mechanical damage.

Do-it-yourself plastering outside the walls of the house, subjected to stable negative influence high temperatures and solar radiation, most often performed by polymer mixtures. Synthetic resins can also be included in their composition: acrylic-styrene, polyvinyl-acetate, etc. These mixtures bond well with almost any kind of bases.

Like polymeric, silicone mixtures can withstand the harmful effects of solar radiation and various mechanical factors for a long time. They have a long service life and storage, and are also able to provide good waterproofing.

house plaster

For the manufacture of mineral mixtures, dry cement is used. To get started, it is enough to dilute this mixture with water to the desired consistency. Mineral-based plasters are non-flammable and allow the wall to breathe. However, their main drawback is poor adhesion, which requires additional preparation of the base. The main advantage is its self-preparation.

Preparations for work

In order to properly prepare the surface of the walls for applying the plaster mixture, it is necessary:

• Remove old, weakly adhering plaster, if present.

If possible, remove the sagging and bumps. Being too lazy, you will be faced with the forced application of thick layers of plaster, which will cause waste of materials, effort and time during the work.

• Remove any contaminants from the surface.
• If you are dealing with a brick wall at home, then it is worth embroidering the seams, that is, expanding and deepening the joints. Thanks to this, the applied facade plaster will “cling” to the base of the wall more firmly. It happens that a new brick laying is carried out in advance “into the wasteland”, which can significantly reduce the time of preparation for the main work. After stitching brick walls you need to prime and let them dry completely. And only then you can start plastering.

If blocks larger than standard bricks were used in the construction of walls, then there is no need for jointing. There will be much less seams here and places for a hook too.

• If the wall of the house was erected using the "rough" masonry method or smooth reinforced concrete slabs, then proceed as before. On the surface of such a wall, you can immediately stuff a special plaster mesh. The wall must be pre-treated with a deeply penetrating primer.

Walls made of concrete or aerated concrete require a different attitude. Before proceeding with the finishing process, you need to figure out how to plaster them correctly. The selected facade plaster must be weaker in strength than the base. This will help to avoid the appearance of layer tension at the joints. The mixture should allow the wall to breathe, because concrete can accumulate and release moisture. The ability of the solution to penetrate steam will protect against condensation and the appearance of fungi.

Fungus on the plaster surface

Decorative facade plaster is applied only on the main layer of the mixture, the thickness of which is from 1 to 5 cm. Before this, the base must be primed or finished with a special mounting grid installed on a liquid basis. If work is carried out at high temperatures, then the layer must be periodically sprayed with water for uniform drying. Otherwise, the outer layer dries earlier than the inner one. This will inevitably lead to cracks.

Installation of special beacons

Plaster beacons - rails fixed to the wall from metal profile. Moving along them, the spout of the trapezoid rule turns the freshly applied solution into a perfectly flat plane. To achieve this result, you need to make them properly installed.

How to do it right:

• The prepared wall is hung with a load to determine its vertical deviation from the level. If the tops “sink”, then the vertical deviation is greater at the top than at the bottom. Therefore, during the installation of beacons, you will have to add a solution under them. And vice versa.
• Take the beacon and shorten as needed. The thickness of metal beacons is 6 or 10 mm, and the length is 3 or 4 meters. Please note that 6 mm beacons are more flexible. In view of this, it is more reasonable to use 10 mm. However, because of this, the thickness of the plaster layer will increase by 4 mm.
• Smear the wall approximately 20 - 30 cm from the corner with one line in the form of dots. Leave approximately 50 cm between the beacons. The mixture should be thick. Piglets should be 5-15 cm in diameter, and the height will depend on the thickness of the future facade plaster. The height is greater, the thicker the layer. Also don't forget to consider where the biggest shift from the level is.
• Attach the beacon and lightly press it into the mixture. Then attach a rule with a built-in level to it and, pressing or pulling the beacon, reach the desired wall vertical. We immediately clean the lighthouse from sagging, and smooth out the protruding places with a spatula.
• When the solution adheres, carefully seal the voids that remain under the beacon. Do the same in reverse.
• Try not to have more than 1.7-1.8 m between adjacent beacons. It is more convenient to handle the 2-meter trapezoid rule during leveling work.

If the size of the wall exceeds 2 meters, then add guides between the beacons placed at the corners.

How to properly apply plaster

Plaster work is also divided into 3 main stages.

splashing

The cement mortar is diluted to the state of rare sour cream. If you are using dry or ready-made mixes for outdoor use, then everything must be done following the manufacturer's instructions.

Then, with a ladle, we spray the solution on the entire wall. The mixture should not splash, but pounce, and with reasonable diligence. The more “roughness” comes out, the better. We are waiting for it to dry.

Application of the main layer

Dilute the solution to a state of thick sour cream and sprinkle between two lighthouses on an area equal to 40-60 cm in height. The largest total thickness of all layers of plaster should be no more than 5 cm. Having attached a trapezoid rule to the beacons with a narrow side, begin to move it from side to side. Try to ensure that the edges of the rule do not leave the lighthouses, while at the same time slowly moving up.

So all the excess will be cut off and the plaster of the outer walls will become as flat as possible. If in some places the solution was put a little less than necessary, then you need to throw it in and perform all the steps again.

Grouting plaster

If you used cement plaster, then after the mixture has dried, grouting is performed. To do this, use a wooden or plastic grater. The purpose of the process is to prevent the appearance of cracks, as well as to smooth out the smallest irregularities and close up minor shells remaining after the rule.

Grouting is carried out in a circular motion in a spiral. From a larger circle to a small one, we “stretch” the solution to make a tubercle. And in the reverse order - we level it completely.

The technology of plastering the facade from the outside with your own hands is not so complicated as it might seem at first. With simple tools, time and desire, all these types of work are quite doable without outside help.
