Facade plasters are only good for bricks. It's no secret that often brickwork leaves much to be desired. Even if the masonry is made of facade decorative bricks, but crooked and sloppy, the house looks sloppy.
Facade plaster well hides the flaws of bricks and brickwork.
Of course, now there are a huge number of techniques and materials for decorating the facade, but plaster remains the leader in this matter. Not only because it is affordable, cheap and easy to process, but also because the development of this material also does not stand still: today, facade plaster is presented in many types. Therefore, it is so important to be guided in the question of how to properly plaster the facade with brick and what types of coating can be used in this case.
Ideally, plaster correctly and efficiently brick house can a team of professional builders, those who have special schools and long experience. But as soon as you take on this work yourself, it is important to know the sequence of the performed manipulations:
- It is necessary to prepare the facade of the house: remove dirt, embroider the seams.
- Next - prime the walls, that is, treat them with a special compound, on which the plaster fits better.
- It is necessary to reinforce the walls. For this, a conventional facade mesh is used, which is nailed to the brick.
- Then beacons are installed - metal strips along which the surface is further leveled.
- After that, the plaster solution itself is applied.
- And the last thing is grout.
Building codes assume the installation of a mesh before starting plastering, only if the thickness of the outline is more than 3 cm.However, it makes sense to use it in any situation. It will prevent cracks on the facade and improve the adhesion between brick and plaster.
It is imperative to use a grid when plastering the basement of the building. This part is usually made of concrete, so reinforcement is necessary.
To carry out facade work, you will need the following tool:
- rule;
- ladle;
- grater;
- half-scraper;
- putty knife;
- maklovitsa.
Sequence of work
Algorithm of actions:
- After fixing the mesh over the entire area of the facade of the house, the guide profiles of the beacons are installed. They are fixed strictly vertically along a plumb line and horizontally along the water level on alabaster. The distance between the profiles is slightly less than the length of the plastering rule.
- Internal and external are installed on all window and door openings metal corners... They will also prevent the appearance of cracks in the plaster.
- A thin layer of very liquid plaster is applied to the walls, the method is called spray.
- Further, the plaster is thrown between the beacons, creating a layer of soil. The layer can be thick, so the material must have a thick consistency.
- After the plaster dries a little, after about 20 minutes, as a rule, the top is carried out from below along the metal beacons, smoothing out the irregularities. The resulting holes in the surface of the coating are again covered with a solution. Again, they carry out the rule. And so as many times as necessary, until the surface becomes level, without pits and potholes.
- The next day, when the plaster has dried, you need to remove the metal beacons and wipe the resulting voids with a solution.
- Before applying the finishing layer, it is necessary to properly prime the surface with a solution suitable for the plaster.
- Finishing, decorative facade plaster is applied in a thin layer. Different tools are used for this, depending on the desired pattern. They can be metal, rubber or regular rollers.
It is necessary to plaster the facade in dry weather: even if it rains in summer, the water will wash out the wet plaster very quickly, and heavy rain can remove it all the way to the brick.
To avoid the appearance of cracks, do not plaster at sub-zero temperatures.
Types of facade plaster
As mentioned above, plaster can be of several types:
- Mineral. It is the most common due to its low cost. Well suited for plastering bricks and concrete. However, it is unstable and short-lived. The range of colors is very narrow, so such plaster has to be painted.
- Silicate. The composition of the material includes liquid glass, so this plaster is quite durable. The price is quite high, on the other hand, when using this material, facade work needs to be done very rarely. Also suitable for work on brick and insulated surfaces.
- Acrylic. This is a very flexible facade mixture that is suitable for working with any walls: brick, concrete, and insulation. This plaster is vapor-permeable and water-repellent. Easily washed away from dirt. It dries quickly, so she needs to plaster more actively.
- Silicone. Any surface can be treated with such plaster, it is very elastic and durable. Due to its characteristics, it never cracks. However, vapor permeability is low. And one more drawback is the very high price.
In general, all facade plasters have certain advantages and disadvantages, therefore, before starting to perform facade work, consult with experienced builders. They will tell you which plaster is better for brick, which for concrete, which for insulation. In this case, rely on your financial capabilities, because facade work has always been quite expensive.

A little about pricing
As mentioned above, facade work and materials are very expensive, no matter what surfaces you need to work on: brick or concrete. The price for brick plastering work is comparatively lower than for insulation. Also, the price depends on the thickness of the plaster outline. Thus, the most low price is approximately 350 rubles per 1 m².
It should not be forgotten that the casting of door and window openings is charged higher than the plaster of flat walls, again due to the laboriousness of the process.
The price for the material also has a wide range and depends on the manufacturer. So, the usual facade mineral plaster can cost from 400 to 700 rubles for a standard 25-kilogram bag.
A bucket of acrylic plaster weighing 25 kg can cost at least 1,700 rubles. The same bucket of silicone plaster costs from 2,000 rubles.
It is necessary to buy material based on the coverage rate. For example, consumption ordinary plaster for 1 m² - about 3-4 kg. That is, a standard package weighing 25 kg will cover 7-10 m² of the facade.

When planning facade work, remember: if you managed to save on materials and labor costs for workers, then, most likely, such plaster will not last long. Since this means that the material is of poor quality and the workers are most likely not professionals. And all the work in a year will have to be repeated, since the miser pays twice.
Correctly carried out external plastering of the house allows not only to refine the facade, but also to significantly improve its operational characteristics.
It is not surprising that, despite all the innovations that have appeared in the field of facing buildings outside, many prefer plastering.
Benefits of plaster
Regardless of the type of cladding chosen for the house, plaster has a number of advantages:
- democratic cost (price is perhaps one of the main factors explaining why there are so many people who want to improve 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 correctly 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 mixes 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.
Due to the heterogeneous texture, you can easily hide small defects in the walls of the house from the outside (various depressions and protrusions); they organically fit into the overall picture, complementing the texture in their 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 from the outside, or to paint the walls after applying the plaster.
How to properly plaster the walls of a house
To properly plaster the house from the outside, you can use a special plastering machine, or you can apply the solution yourself.
For self-application of plastering 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 the facades correctly.
The main thing is to strictly follow the manufacturer's recommendations on the use of plaster, its application and drying time. If you have any doubts about your abilities and capabilities to make the plastering correctly and efficiently, it is better to seek the help of qualified workers.
Preparation for plastering
In order to plaster the house from the outside correctly and without a hitch, before starting the facing work, you should prepare the facade.
The main thing is to prepare the wall itself for plastering: remove the remnants of the previous finish, clean the surface, get rid of dust and dirt.
Using special tools, you should degrease the surface and remove fungus and mold, if any. After preparatory work a primer is being 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 you intend to use embossed plaster, then leveling the wall is not at all necessary.
Instrument preparation
To correctly carry out the plastering of the facade, you do not need any special tools. Everything you need can be bought at a regular building materials store: a few spatulas different kind, roller, brush, mortar container and sandpaper.
The plaster can be sprayed onto the walls, making the job quicker and easier.
To avoid skin irritation and contact with the eyes, it is better to carry out plastering work with glasses and gloves. (To protect instruments, it is better to rinse 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: you should throw the solution onto the wall with sharp movements. If you have a plastering machine, then it will be easier, although more expensive. The first layer should not exceed 4 centimeters.
When the first layer is dry, the second is applied. In the future, depending on the type of plaster mixture, grouting or the formation of a relief using rollers is carried out.
On the final stage the plaster is painted in the desired color. If the solution is already colored, 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 the 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 off with compressed air.
Features of plastering a wooden house
Exterior plaster has excellent contact with any building materials: brick, concrete, drywall and wood.
Plastering a wooden facade is necessary to seal the gaps between the boards, to prevent them from drying out and the appearance of mold and mildew.
You cannot plaster a wooden house immediately after construction, because the house must stand and sink.
If you start plastering right away, then in a couple of years the cladding 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 mortars 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 the mineral plaster to adhere well to the wooden facade and protect 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 surface to be treated and maintains 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 extend the life of the facade and the structure itself.
Conclusion
Plastering is far from the easiest way external processing facades, however, it has many 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 view, which will favorably distinguish it against the background of other buildings.
Any owner of a country house, summer house or cottage sooner or later faces the need to repair or restore the outer surface of a building, which, during operation, is negatively affected by significant changes in humidity and temperature, various climatic phenomena such as snow, rain, wind gusts, frosts, etc. .d.
Traditionally, for leveling the surface of the outer walls of the house, they are used different kinds plasters that modern domestic and foreign manufacturers offer in a huge range. Knowing how to plaster the facade of a house, and choosing the right materials, you can quickly and efficiently finish any surfaces, regardless of their volume and structural complexity.
The advantages of modern plasters
Modern plasters for preliminary and finishing facades have excellent operational and technical properties:
- waterproof;
- soundproofing;
- thermal efficiency;
- fire protection;
- water-repellent qualities;
- excellent vapor permeability;
- frost resistance;
- increased mechanical strength.
The combination of these properties makes plaster an optimal material for facades, and affordable cost, low requirements for preliminary surface preparation and ease of application make this material one of the most optimal in its price category.
Currently, there is a large selection of plasters on the market, which can be decorated and painted and can give the surface a different structure and texture. With the right choice and application, such materials can achieve a stylish, aesthetically pleasing effect. The composition of modern plasters can include various fillers:
- Quartz sand.
- Marble chips.
- Granules of various colors.
- The smallest elements of glass and other materials.
Decorative plaster can be immediately sold with a color tint or tinted with special paints to match the required range.
It is most convenient to tint the plaster according to the catalog using special equipment directly in mall or in a specialized organization. This is very convenient if in the future you have to buy additional material in case of a shortage or for maintenance cover.
Features of applying plaster
For plaster, the best surface is a wall with a slight roughness, which ensures high-quality adhesion of the material. Expanded clay concrete and brickwork are excellent for applying facade plaster. However, it should be remembered that in case of significant differences in level, a preliminary leveling of the base should be carried out using a cement-sand mortar and a reinforcing mesh. For better adhesion, a preliminary spray of plaster is made on a smooth surface, and then a fine finish is applied. IN wooden houses, before how to plaster the facade of a house panels of insulation or sound insulation are mounted on the walls: mineral wool, cellular plastic, sprayed thermal insulation, etc.
Facade plaster is applied only on a dry surface, subject to the temperature and humidity conditions. For different types materials have their own rules of work, which should be familiarized with before starting work on plastering surfaces.
Plastering technology
Before starting work, an external hydro and vapor barrier must be applied, the roof and fasteners for the drainage system must be installed. The surface of the facade walls is cleaned of dirt and dust, bitumen stains and salts protruding from the masonry. At ambient temperatures above 25 degrees in dry weather, the external walls to be plaster must be moistened.
Experts recommend applying a preparatory layer with a thickness of at least 20 mm under any decorative plaster in order to avoid further efflorescence.
Depending on the materials used and the ambient temperature, the precoat must be cured for at least 7 days.
The finishing layer is applied in several steps, usually 2-3 steps are used, each 10-15 mm thick. You can create a certain texture on the surface of the walls using a still plastic solution while it is not frozen. For this, special spatulas or a bristle brush, a bevel with semicircular teeth and other painting tools are used. For example, by drawing along the rule, a small groove can be obtained, the parameters of which depend on the size of the teeth of the small.
A beautiful decorative surface on the facade can be obtained using a raised roller, spray from a brush or even a regular broom. The originality of the facade will be given by various pebbles, crushed stone or gravel added to the finishing solution.
Video
Today plaster is very popular, which in a simple way is often called "bark beetle". This video will show you how to do the job of applying this plaster.
Facade plaster for a brick wall is used quite often. After all, this is a fairly comfortable and durable material. Plastering of external insulated walls can also be made, for example, it is successfully used for finishing foam on the outside of the room.
How to plaster the outer walls correctly, we will consider today. Also in the video in this article you can see all the details.
Plastering the walls outside the house is done different materials and when buying, it is advisable to pay attention to the packaging. It can be packed in a bag or bucket, which will give the information necessary for familiarization regarding the characteristics of the plaster and the places of its application. Let's look at how to plaster the walls outside and what to look for when buying materials.
The packaging contains the following data required by the consumer:
| Plaster type | It can be purely cement based or with added limestone, restorative or thin layer. |
| Terms of use | Plaster can be for interior or facade. |
| Weight of one package | This information is required in order to calculate the required amount. Most often, packing is carried out in twenty-five kilograms. |
| Application temperature | It talks about the temperature range at which work can be performed. |
| Adhesion and compressive strength | These indicators indicate the strength of the applied plaster and its ability to adhere to various substrates. It is desirable that the numbers are as high as possible. |
| Layer thickness | As a rule, this indicator is indicated in a certain range. |
| Steam resistance coefficient | The higher the index, the worse the permeability. |
Attention: Before applying the plaster to the facade of the building, it is necessary to carefully prepare the base for a stronger adhesion of the material to it. If you neglect the preparation, then the plaster will not last long.
How to plaster external walls: the video will show the entire further progress of the work and the instructions will describe everything point by point.
Surface preparation
To prepare the surface, the following procedures must be performed:
- Removing old plaster and other materials from the surface. This is necessary to improve the adhesion of the new plaster to the surface. You need to take a hammer or piece of wood and knock on the surface of the old coating. If a dull sound is heard, this indicates that the old plaster is not holding onto the base. You can knock it down with the same hammer or puncher.
- Removing surface protrusions. This can be done with a hammer drill or chisel hammer. If the base has large protrusions or irregularities, then thick layers of plaster will have to be applied, which requires additional costs for related materials and more time.
- Cleaning the base from construction dust, dirt, oil and other traces.
- Treatment of the cleaned surface with a primer (see What a primer is for: technological nuances of finishing work) or impregnation for the corresponding surface.
Attention: In the case when plastering is done on brickwork, you can additionally deepen the seams with jointing. It will help improve the adhesion of the plaster with brick wall because it will penetrate the seams and hold on more firmly.
- There is an option when the brick is initially laid with an empty seam on the outside, which excludes the jointing process in the future.
- If the wall is made of blocks, it makes no sense to deepen the seam, since it is much thinner than in brickwork and the adhesion to it will be negligible.
- Smoother surfaces, such as reinforced concrete slabs, need to be impregnated deep penetration, it will remove the remaining dust and improve the subsequent adhesion. After that, it is necessary to fix the plaster mesh on such a surface, which will create an additional hook for the solution. After you can read preparatory stage finished.
Installing beacons
Plaster beacons are straight guides made of metal, which are mounted on the wall alternately in accordance with the required level.
So:
- A plaster mortar is stuffed between them and leveled by the movement of the rule along these guides. This approach to plastering allows you to create an incredibly flat surface with your own hands, even for a person who has no experience in finishing. All that is required for this is to perform competent correct installation beacons. Consider the sequence of installing beacons.
- Using a manual plumb bob or electronic level it is necessary to measure the deviation of the wall from the vertical. If at the top or bottom of the wall is heaped further from the plane, then in this place more mortar will be required for attaching the beacons. The most common are lighthouses with a thickness equal to six or ten millimeters. The standard length is three meters.
- It is necessary to measure the height and cut the beacon in accordance with the obtained values. Thicker beacons are recommended. They have greater strength than thin ones, which easily bend when held by a rule and can distort the intended level. But it should be borne in mind that the thickness of the applied layer will be greater.
- At a distance of thirty centimeters from the corner, apply the required layer of mortar along a vertical line for attaching the beacon to the wall. The distance relative to the attachment points of the beacon should be about fifty centimeters. The beacon is attached to a densely wound plaster solution for quick drying and preventing slipping.
- We attach a beacon to the applied solution and press it a little.
- To the installed beacon, we apply a rule with a level and with light movements aligns the beacon vertically. It is advisable to buy a longer rule, it will allow you to more accurately set the level. If the solution on the wall goes beyond the level of the lighthouse, then it must be leveled. The rule should be cleaned of the solution immediately, otherwise adhering particles will knock down the level.
- It is necessary to fill the solution into the space under the beacon between the fasteners and wait for it to dry. This procedure will reliably fix the beacon.
- In the same way, you need to install other beacons on the surface. The distance between them should be no more than one and a half meters. This will be more convenient and will allow you to work with a two-meter rule, but you can also place it under a shorter one.
- A few beacons will be enough for a wall in the room, but the facade of the building is long, so you will need to install significantly more rails. They are installed in exactly the same way.
Plaster finishing
Facade plastering of a brick wall is done in three stages. Moreover, it does not matter at all whether it is plastering old external walls or new ones.
Attention: Before starting the application, it is important to determine the unevenness of the walls. This is best done with a fishing line and pull it diagonally across the plane. Then, by placing a level, you will immediately see all the errors and deviations.
| Pouring over solution
| The process begins by mixing the solution to the consistency of sour cream.
|
| Application of a starter layer
| The solution must be diluted to the required consistency and applied in strips between two beacons. This can be done using the starting mixture, it has a larger fraction.
|
| Grout mortar
| After applying the cement mortar to the wall and drying it, wipe it off.

Exterior foam plaster
Many people do the plastering of the exterior walls of a house using polystyrene foam (see Plastering using foam plastic - how and why it is needed). This is done after the insulation has been carried out.
This work is somewhat different from applying simply to the plane of the wall.
Everything is done as follows:
Note: It is assumed that you have correctly applied the foam to the plane. You can read about this on our website. That is, your entire plane is in one axis.
- First, we apply a construction mesh over the surface of the foam. The plaster will hold on to it and the bond will be strong enough.
- Now, using a wide spatula, apply a starting layer of plaster. After all, we already have a flat plane, so the layer will not be large and the price of plaster will be lower than when leveling the surface.
- We are waiting for the surface to dry completely and apply a small layer of finish.
- We are waiting for drying and walk along the plane with a construction mesh. We will immediately see all the shells.
- We putty the sinks and grind the plane.
- Cooking for painting, applying a primer. We are waiting for complete drying and apply the dye.
Finishing plaster for external walls is applied entirely by hand, since the technology is not particularly difficult. The main thing is to get acquainted with the process of preparation, application and grouting, purchase necessary materials and fixtures, and then get to work. If you take your time and follow all the recommendations, everything will definitely work out!
Plaster is today considered one of the most demanded materials for exterior decoration of a building. It protects the facade from unnecessary heat loss. If carried out correctly renovation works, it is possible subsequently to significantly save energy costs for heating the house.
Also improves the appearance of the building. The surface of the walls after proper processing is not subject to negative environmental influences, does not deteriorate for a long time. How plaster is applied correctly should be known to every builder or repairman.
Advantages
Today it is quite high if you seek the help of professional builders. The average price of such works today is about 350-400 rubles / m². Therefore, many decide to perform all the actions on their own.
Using the presented type of finish, you can get high quality the end result. First of all, it should be noted the aesthetic appearance. A variety of textures, shades allows you to create a fashionable, stylish design outside of the house.
The price of which today is acceptable for almost every real estate owner, is easy to use. Depending on the type, manufacturer of dry mixes, you can purchase dry mix (25 kg) from 350 to 500 rubles.
The products on sale today protect walls from moisture penetration, are resistant to low temperatures, and prevent corrosion.
Types of plaster
Today, many varieties of mixtures are used for facade plastering. These are textured solutions that differ in a number of characteristics. The most popular manufacturers of dry mixes for such a finish are the companies "KNAUF", "Ts eresit ". Facade plaster may contain various fillers.
To set the required texture for the finish, the mortar contains components of various grain sizes. This can be marble chips, quartz sand, colored granules, glass dust, wood fibers, etc.
To add color to the mixture, dyes are added to it. In this case, you can achieve almost any shade. Tinting is performed in a trade organization using special equipment. This allows, if necessary, to set the base exactly the same shade, if you have to buy a dry mixture. The inhomogeneous structure of the mortar allows you to hide the unevenness of the base.
Finishing methods
You can apply a coating to the facade of the house mechanically or manually. In the first option, you will have to purchase special equipment. Companies such as KNAUF, Ts erezit ", facade plaster whose production is very popular today, they are developing a special line of products that can be applied mechanically to the base. This approach is preferable for professionals who perform significant volumes. finishing works.
For craftsmen who wish to apply the solution to the facade of their home, it is better to do it manually. So it will be possible to save on the purchase of special equipment. In this case, you only need to purchase ordinary tools... To create a certain type of texture, you also need to buy curly spatulas.
In the process of applying the solution in any way, you should strictly follow the manufacturer's recommendations. Only in this case it will be possible to create a durable, beautiful protective layer.
Work technology
Finishing work is carried out according to a certain technology. Correctly performing each stage, you can achieve a good result, even without having experience in carrying out such actions.
Facade plaster for outdoor use, the price of which will be within the power of almost every owner of a house or cottage, is intended for finishing the base of different material... It can be brick, foam concrete, or other types of building materials. The most optimal and inexpensive finishing method is considered to be the use of lighthouses.
The work is done in several stages. First you need to prepare the base, then beacons are installed. Only then can you begin to plaster the facade. This method is suitable for manual application of the mortar. It is important to adhere to the proportions when mixing the dry mixture, as well as the manufacturer's recommendations regarding the drying time.
Preparation of the base
Plastering brick facades or made of any other materials must begin with the preparation of the base. If you skip this stage or perform it with insufficient quality, the result will not be of sufficient quality.
The old finish must be removed first. It is knocked down with a small hammer or wooden block. Where the sound will be dull, the old finish is knocked out with a chisel and hammer. In some cases, you will need to use a hammer drill. Also removes dirt, oil stains and dust.
It is advisable to reduce as much as possible the number of irregularities, bumps at the base of the walls. If this is not done, you will have to apply a thick layer of plaster. Material consumption will increase significantly. Therefore, it is better to properly prepare the surface of the walls than to spend money. family budget for the purchase of additional dry mix.
A brick base requires, in some cases, joining. This procedure allows you to increase the adhesion of the solution to the base. The plaster will hold firmly and the service life of the coating will increase. Some builders leave the facade with empty seams when erecting brick walls of houses. This allows the substrate to be prepared for finishing faster.
For foam blocks, joining is not done. This also applies to walls made of reinforced concrete slabs of "rough" masonry, which have a smooth surface. Such types of materials are immediately filled with a grid for plastering facades. It is necessary to first apply a layer of deep penetration primer. It will strengthen the adhesion of the mortar to the base.
When choosing a primer, you should give preference to trusted manufacturers. It is also necessary to adhere to the correct concentration of the solution. In this case, the film will turn out to be strong.
Lighthouses
Assumes the use of beacons. These are metal guides. They are installed on the base to indicate the level of application of the plaster. The rules, leveling the layer, slide their nose along the tops of the lighthouses.
It is believed that the application similar way finishing allows even a non-professional to make a perfectly smooth surface. However, the master needs to familiarize himself with the technology of installing beacons on a plane.
It is necessary to determine the verticality of the wall with a plumb line. Deviations from the level must be determined before installing the guides. If the top of the walls is inclined inward, this indicator must be taken into account. Beacons are adjusted to a specific size. The excess height of the guides must be cut off.
Installing beacons
Produced after installing beacons. From the corner, at a distance of 20 cm, a solution is applied pointwise. Their diameter should be about 5-15 cm. The height depends on the intended layer of plastering. If the rule is 2 m long, the beacons can be installed 1.7 m apart. If the wall is too large, the guides need to be made more frequent.
Each beacon is placed in a solution and slightly sunk there. A level rule is applied at the top of each element. If necessary, the position of the beacon is adjusted to achieve the ideal vertical finishing position. To avoid deviations, errors, it is recommended to pull the "laces" between the two extreme elements during the alignment of the beacons. After the solution has dried, the resulting voids under the lighthouse are filled with putty.
Application of the first layer
Plastering takes place in 3 stages. Mechanical plastering of the facade allows you to complete all actions faster. However, in this case, it is imperative to work in a respirator and goggles. Otherwise, the solution may enter the respiratory tract or eyes.
The dry mixture must be diluted to the consistency of liquid sour cream. In this case, the manufacturer's recommendations must be taken into account. There are also ready-made ones on sale. Some professional builders recommend adding PVA glue to the solution. It will add extra strength. The putty will fit well on the wall.
The solution is applied to the wall with a ladle. The mixture must be poured onto the base without pouring it. Roughness on the top layer is encouraged. After surface treatment, the solution must dry.
Base layer
At the next stage, the main facade plastering... To do this, you need to prepare a solution. It should be like thick sour cream in consistency. It is thrown onto the surface between two lighthouses. It should be noted that the thickness of all layers of plaster should not exceed 5 cm.
With the narrow side, you need to press the rule against the beacons. The tool is moved from side to side. The edges of the rule should not fly off the tops of the guides. The movement is made in an upward direction. Surplus is cut off. This results in a perfectly smooth surface.
If during the leveling process it turns out that there is not enough solution, it should be added. The mixture is thrown into the formed hole. Then again the rule is carried out on the surface.
Grout
Assumes the final stage. It is necessary to grout the surface. This procedure is carried out after the cement topcoat has dried. For this, special graters are used. They can be made of foam or wood.
If a cement-free filler is used, the manufacturer's recommendations should be followed. They are necessarily indicated on the packaging.
Grouting allows you to smooth out small irregularities, to close up shells after applying the rule. Grouting is performed in a spiral. Circular movements begin with wide movements, gradually moving the instrument towards the center. WITH large circle the tubercle in the center is stretched. In the opposite action, it is completely leveled.
After considering how it happens facade plastering, everyone will be able to perform the procedure well. In this case, the surface will be perfectly flat. Following the recommendations of professional repairmen and builders is a guarantee of a good result of the final work.
