Mechanical plaster of walls in fun or. What is the difference between machine-applied plaster and hand-applied plaster? Electric units for machine plastering

Any type of plasters, classical or decorative, can be done manually or by machine. Both of these technologies have their own characteristics, so even among experts there are different opinions about which method is better. Let's look at the difference between plaster machine application from manual.

Key differences and similarities

Composition of the preliminary preparatory work is the same in both technologies. True, machine-applied plaster will require the installation of guide beacons in increments of ≤ 1 m, while hand-applied plaster allows for longer distances.
The difference between machine-applied and hand-applied plasters lies in the composition of the mixture used. For the first, components are added to the solution to allow its use in a plastering station. These additives prevent the mixture from sticking to the working surfaces of the plastering unit and allow you to automate the processes of preparing, mixing and laying the solution. This mixture is cheaper.
To manually apply the mortar, only classic tools are used (plaster ladle, trowel, spatulas). And for mechanical spraying you need a plastering station, supply hoses and tips in the form of a nozzle or a semi-automatic machine, in which the mixture is poured into a tank with manual mixing, and the solution is supplied through a hose using a compressor and a cartouche gun.
The difference between plasters when applied by machine is that the most physically difficult operations are performed; the preparation of the solution and spraying on the surface to be plastered is mechanized. This leads to high productivity (several times higher than hand technology) and the possibility of reducing the composition of the work team.
Sketching a solution by hand is labor-intensive and time-consuming. The solution, due to its rapid hardening, is prepared in small portions, which further increases the time it takes to complete the work. In addition, plastering is carried out in several layers, the subsequent ones are laid after the previous ones have been leveled and when they begin to set. Under these conditions, it is almost impossible to prepare the entire solution with the same consistency. As a result of this technology, uneven drying of the plaster occurs, leading to a high probability of subsequent cracks and unevenness. Putty becomes necessary. The mechanical method allows the mortar to be laid in one thick layer. The mixture, constantly stirring, becomes homogeneous. The supply of mortar mixtures under pressure ensures a tight fit without voids, which reduces the risk of peeling and cracks. The walls are characterized by good evenness and smoothness, which allows wallpapering without further finishing.
The consumption of machine-applied plaster is less due to its uniform distribution over the surface and the saturation of the solution with air bubbles, which increases its volume.
When machine plastering the external walls of one-story buildings, no scaffolding is needed.
The cost of performing work with manual plastering is higher.

Both technologies require professional execution; only experienced specialists will ensure proper quality. The choice is yours.

Mechanical plaster for walls appeared not so long ago, but this type repair work took a strong position, having established itself with the best side. Before you start plastering, you need to familiarize yourself with how the work is carried out and whether it is rational to independently carry out such a scrupulous task.

There is no doubt about the quality of work done by professionals. Choose companies that have a lot positive feedback. One of the companies with a good reputation is Shtukaturim.rus.

What is it?

There is no such thing as mechanized plaster when it comes to dry mixtures for plastering. However, plaster solutions are universal, suitable for both manual and machine methods.

If we talk about mechanized plastering as a way of working, then people try to simplify their life as much as possible, and the construction industry is no exception. Machines have completely replaced manual labor in many areas, and it is no wonder that there is a desire to somehow make the hard work of plastering walls or ceilings easier. Thus was born the idea of building a mechanism that could perform the most unpleasant and labor-intensive aspects of plastering work.

Mechanical plastering is the same process of plastering walls, but using special machines that make all the work much faster and easier. Thus, applying plaster by machine takes 5-6 times less time than by hand, while the quality of the work is a level higher.

Execution plastering works with the help special equipment requires not only the availability of this very equipment, but also special knowledge and skills. For an unprepared person, it is better not to undertake this, since the likelihood that everything will work out the first time is extremely low.

Ideally, automated plastering should be carried out by a team of professionals, since it is impossible to cope with a plastering machine alone.

Peculiarities

Total for application automatic method Two types of plaster compositions are used:

gypsum based;
cement-sand mixtures.

Depending on the type of composition, the set also varies characteristic features, pros and cons. Thus, gypsum plaster is more in demand in modern market. Many are attracted by its aesthetic side - pleasant white after drying.

However, the advantage of the composition is not limited to external properties alone:

Since gypsum acts as the main element in such plasters, they can safely be classified as environmentally friendly clean materials, since gypsum is of completely natural origin.
The gypsum plaster layer weighs very little, which greatly lightens the load on the surface.
After drying, the gypsum mixture does not shrink or deform. This logically leads to the fact that cracks do not appear on the walls: the surface remains smooth and neat.

Another important factor is the high porosity of the material. Thus, when wet, water quickly evaporates from the surface, and wetting itself does not lead to the development of mold fungi.
The heat and sound insulating qualities of the gypsum plaster layer are also important. It conceals sounds passing through the wall from neighboring rooms, thereby increasing the overall soundproofing background of the apartment or house.
Gypsum helps regulate the indoor microclimate by absorbing moisture from the air.
Treatment with gypsum plasters is indicated in cases where it is necessary to reduce the risk of fire, since the material is not very flammable.

The disadvantages include the high cost of materials compared to sand-cement mortars, however, it is worth considering that the consumption of gypsum plaster is less. And also use the gypsum version in conditions of high humidity - do not best idea: The plaster may peel off.

As for cement-based plaster compositions, they also have their pros and cons. First you need to focus on the positive aspects:

As for strength, the cement option is best choice. It is reliable, allowing less frequent repairs and reconstruction of the plaster layer.
Cement-based plaster adheres well to the surface. There is no need to specially prepare the base for plaster, take some special measures. She will still stick to him well and become whole.
Cement mortars are well tolerated high humidity, thanks to which they can be used to decorate rooms such as the bathroom, for example. But also thanks to this property they can be applied outside the house.
Finally, compared to plaster cement mixtures not so expensive due to the low cost of the materials included in their composition.

There are many disadvantages of cement-sand plasters:

They cannot be applied to every material. They are not “friendly” with plastic and wood; painted surfaces are also a bad option.
since the material weighs quite a lot, they first check whether the wall can withstand the weight of such a plaster layer. To do this, you need to perform special calculations.
After applying the plaster, it is necessary to carry out work on puttying and leveling the surface.
The disadvantages include long term drying time of the solution is approximately a month.

In general, mixtures for mechanized application There are no special differences between any of the types. The faction can be any. The machine is pre-set for a particular solution or mixture.

Specifics of the method

Like everyone construction view works, mechanical plastering of walls has its pros and cons. It is best to start considering the specific features with the advantages of the method:

Automatic application of plaster differs from manual application in the amount of material consumption. So, per 1 m2 mechanically approximately 13 kg applied, and 16 kg by hand. If you consider that you need to apply at least three layers, the difference will be significant.
All processes are greatly simplified. Now you don’t need to mix the solution or constantly prepare new portions. Human labor has practically been replaced by machine labor.

Due to the fact that mixing is carried out in a constant mode, and even water is supplied automatically, the solution is homogeneous. This will ensure that it does not crack or warp over time.
Applying plaster using a machine is much faster. Thanks to this, the plaster dries evenly. There is no “Dalmatian” effect: it’s dried out here, it’s set there, but here it’s still completely damp. Because of this, there are no joints, and the plaster layer is monolithic.
Some work that is usually carried out after plastering is no longer necessary. These include, for example, puttying.

Since the walls are already perfectly smooth, there is no need to putty them.

In addition to the above, the hardware method also has several disadvantages:

The high cost of equipment has an impact. For independent use, purchasing it is irrational, as is renting. In terms of cost, hiring a team of workers working using this technology will cost the same amount.
To operate the machine, you need two people, as well as one more person to level the wall.

If you decide to do mechanical plastering yourself, you still won’t be able to do it.

Types of work

Mechanical plaster is used everywhere. There is no one area that this technology would be limited. The only limitation is temperature regime. Do not carry out work outside in winter. The surface should not be colder than 20 degrees. And this requirement is determined more by the specifics of the solutions used, and not by the hardware method itself.

The mechanical plastering method is successfully used for both external and interior work. The only thing worth remembering is which mixture to use and where. If both compositions are acceptable for interior work, then only cement is suitable for facing, since only it has the required set of characteristic qualities. It is worth considering each of the areas in more detail in order to better understand the specifics of working with mechanized plastering in certain conditions.

Interior work

As mentioned above, both types of plaster are suitable for interior work. It is logical that a gypsum-based solution turns out to be the best, due to its positive properties, as well as the fact that it is easier to work with. Fewer layers will be required.

Both a plus and a minus at the same time is that gypsum dries very quickly, so working with it requires efficiency. It will be necessary to wash the equipment immediately after applying the layer, otherwise it will be almost impossible to clean the gypsum plaster from the machine.

Before applying the plaster mixture using a mechanized method, all the same preparation will be required as for manual application. The walls will need to be primed or moistened with water. Only after this can you proceed directly to spraying the plaster composition.

When working with cement-sand plaster, you may need to first apply a mounting mesh to ensure that the plaster layer stays in place. This is especially true for bases with almost zero adhesion, for example, monolithic concrete.

Facing coating

Work outdoors should only be carried out at above-zero temperatures. This is due not only to the fact that the surface must be prepared, but also to comfort. Whatever one may say, mechanical plastering is hard physical work, and the workers performing the application and leveling must feel comfortable.

Only cement plaster is suitable for cladding. Working with it requires preliminary debugging of the machine. It is important to take into account that there are fragments of a large fraction, so all settings must be set according to the data indicated by the manufacturer on the packaging. This especially applies to decorative options, for example, bark beetle plaster.

In addition to for what work which composition is used, it is important to know in what forms they are sold. Both ready-made and dry plasters are available for sale.

With the help of special equipment you can work with both.

Applying dry mixture

The beauty of the mechanized method is that it allows you to completely eliminate manual labor in relation to diluting and applying the mixture. Before starting work with dry mix, it is important to ensure that the machine has access to running water and electrical network. To power it, a voltage of 220 W is sufficient.

The work is carried out as follows: The dry mixture is added to a specially provided container, then the machine independently mixes the solution in accordance with the specified parameters. Thus, the plaster is mixed constantly, and the solution turns out to be homogeneous, airy, and of the same consistency.

This method of work is considered more preferable, since it is cheaper, but the quality of the solution is no worse than when buying a ready-made one.

Walls treated in this way have flat surface, suitable for painting or wallpaper even without further processing.

Treatment with ready-made solutions

Unlike the previous method, in this case the work is carried out using a liquid solution. Here you will only need to take care of connecting to the electrical network. No water supply is needed here. The solution will be constantly stirred, so it will not set ahead of time.

Both methods are suitable for working not only with walls, but also with floors. For example, using a mechanized method, you can make semi-dry or wet screed floors and also plaster the ceilings. The specificity of the solution supply allows this.

The walls will have to be prepared manually:

do sagging;
install beacons.

Plaster mechanical method It only allows you to apply the compound, but not to check the walls in any way.

In general, much less time will be spent on leveling the walls, since the most labor-intensive process - application - is automated.

Necessary equipment and tools

For mechanical plastering you will need not only the plaster mixture itself, but also special tools and equipment. The simplest thing you can do is contact specialists who have special machines for spraying plaster. They will carry out all the work quickly and with virtually no waste. What’s noteworthy is that this option is usually cheaper.

If you or your friends have some equipment for applying plaster mechanically, and they are ready to lend them to you free of charge, it will be easier for you to do all the work yourself. However, it is worth keeping in mind that this will require some knowledge about the selected tool: an understanding of the specifics of its operation, its structure, as well as the difficulties that plastering may involve when using the unit.

Plastering machines and stations

If you have someone to borrow a plastering machine from, you can consider yourself lucky. Renting such a device will cost a pretty penny, besides, it may take some time to adapt to a new application method, and not all work can be done correctly. However, plastering using this method most preferable, because the plastering station produces an even monolithic layer, and the walls turn out almost flawless.

There are two types of machines - screw and pneumatic. In the first case, the supply of solution is fully automated. Ready mix passes through the pipe under high pressure and is fed into the sprayer. In the second case, work is carried out already with ready-made solution, which is supplied to the sprayer under pressure. The machine itself cannot mix the solution.

Pneumopath-hopper

The hopper pneumatic shovel is the simplest tool available and the cheapest. In fact, plastering itself is not carried out here - the material is simply thrown onto the surface using this unit, and that’s all further work must be done manually. However, the pneumoshovel also has positive traits: for example, the ability to work with materials of different fractions and different hardness.

Working with the device does not require special knowledge. The conductor handle is connected to the compressor, after which the solution is filled into the ladle. Pointing it at the wall, you just need to spray. Labor productivity is approximately 60 sq. m per hour of work.

There are hopper pneumatic shovels for both walls and ceilings. The difference lies in the shape of the buckets used.

Pneumatic pistol

A cartouch air gun is perhaps the most inconvenient of all mechanical devices for applying plaster. It is a unit that really looks like a pistol, with a large solution container attached to the top. This is precisely what causes the difficulties in work: it is very difficult to constantly hold such a weight on outstretched arms.

As in the previous case, a compressor hose is attached to the pistol handle, which helps supply the solution under high pressure. The use of a cartouche air gun is only possible when processing walls. There is no such mechanism for ceilings.

In addition to the above, there are even less common tools for mechanized plastering that have not found their fans. These include a plastering robot, for example.

Well-known manufacturers and reviews

Many companies produce plaster mixtures and ready-to-apply solutions. Sadly, not all of them produce quality products. Both gypsum and cement-sand plasters are presented in a wide variety, but only a few companies, especially in the Russian Federation, have acquired a reputation as trustworthy manufacturers.

There are no specialized plasters intended exclusively for cars., so it makes sense to consider the highest quality plasters in general. Below is a list of companies that produce both gypsum mixtures, and cement-sand. Some of them still indicate on the packaging that the product is suitable for machine use, but in fact it is universal. The only possible difference may be the addition of various additives and plasticizers, which speed up the setting and drying time.

This means that without proper work experience, it is almost impossible to apply such plaster correctly in the shortest possible time.

"Prospectors"

The company "Starateli" has focused on the production and sale of dry mixtures for mechanized application. The company believes that one of the most important properties of mechanized plaster is that it does not damage the machine. So, the solution should be washed out well and not clog into key parts of the equipment.

As for diversity, it offers not only gypsum and cement plasters, but also specialized cement-sand mixtures, developed taking into account the specifics of facade work. Additives are added to the compositions, which prevent the plasters from “setting” for 30 minutes, and also make them more plastic.

In addition to wall samples, the Prospectors company produces options for floors, which are also intended for mechanized use. There are compositions that can be applied in different layers: 30-80 mm for screed, 5-30 mm for leveling and 5-80 mm - a combined version.

"Osnovit"

Unlike the previous company, Osnovit did not take it upon itself to declare its plaster mixtures as specialized, oriented only to machine work. Only universal dry plasters are produced, suitable for both manual and machine work.

The “trick” of this manufacturer is that it offers separate plaster mixtures for each layer. So, there is plaster for spraying - preliminary sealing of all cracks and dents on the base, a thin-layer version and a facade one. IN various colors gypsum samples are offered. There is both gray and white. Among other things, the emphasis is on eliminating the shortcomings of plastering materials. In particular, a lightweight cement variety is offered.

All products for mechanized work are suitable for different substrates, some do not require subsequent puttying.

"Volma"

The Volma company was one of the first in Russia to begin producing plasters and other materials suitable for machine spraying. Today the company's product range is quite impressive. There are plasters suitable for application along strings, some for application along beacons, and there are those that are excellent for working without a beacon.

Like others, the company offers both cement and gypsum dry plaster mixtures with a longer setting time. Here it can be up to 60 minutes versus 30 minutes from other manufacturers. It is important to note that the plastering materials from this manufacturer are suitable for machine application to both wall surfaces and ceilings. There are plasters of various fractional sizes, but maximum size particles usually do not exceed 1.25 mm.

The company states that full cycle work with its materials is no more than 2 days.

Knauf

This German company was one of the founders of machine application of various building mixtures as such. She did not stop at producing only plasters, offering consumers also machine putty. The MP and MN lines are positioned as intended for use exclusively by machines, and the company recommends choosing their own devices for this - PFT.

Plaster mixtures differ from each other in the degree of adhesion to substrates, however, the manufacturer guarantees good adhesion even with an unprepared surface. Can be plastered different surfaces: brick, concrete, gas and foam blocks, wood and wood slabs. Information about which plaster is intended for what is available on the packaging.

Touching upon the topic of manufacturers about whom data were given best reviews, one cannot fail to mention the plastering machines themselves. The best equipment It is supplied from Germany, but there is also a good Russian company.

Knauf (Germany)

The company supplies equipment under the trade name PFT. Plastering machines are small in size, but this does not affect their power in any way. In particular, the equipment also differs in power, supplying a constantly mixing solution under high pressure. This allows the plaster to be applied in hard to reach places, for example, slightly taller than human height.

The machines have a structure that completely eliminates the formation of dust, so all work will be completed with minimal losses and with minimal required cleaning in the future. Supply can be carried out at a distance of up to 150 m. The units are usually controlled by two people: the operator who monitors the serviceability of the machine and adds the dry mixture, and the one who directly applies the plaster to the walls.

The machines are on wheels, which makes them easier to move around the room when processing large areas.

Putzmeister (Germany)

This manufacturer does not present ordinary plastering machines, but entire small-sized stations. Each of them can be configured to work with compositions of different fractions up to 3 mm. Today there are two models: Putzmeister MP 25 and Putzmeister MP 15.

Putzmeister MP 25- a model that has been known for a long time. It can often be found among teams that professionally spray plaster using a mechanized method. To work with such a station, special training will be required, since managing it is not an easy task. Suitable for both outdoor and indoor use.

Putzmeister MP 15– a new car that appeared not so long ago. It differs from its predecessor in size and power. So, this option is somewhat more compact and can also work with plasters of large fractions (up to 3 mm). The device is easier to operate than the Putzmeister MP 25.

The price is still high, so you should not purchase such equipment for private use.

M-Tec (Germany)

The advantage of machines from this manufacturer is their intuitive operation. Here you won't have to get any specialized knowledge or skills to operate the equipment. The only thing you need to do is get used to applying the plaster with a sprayer under high pressure.

At all, M-Tec equipment is positioned as suitable for start-up companies, whose employees do not yet master all machine plastering techniques. The functionality of the samples can be called limited, but all necessary operations can be performed. The prices are quite low compared to other samples - approximately 400,000 rubles for a plastering station. Again, a team and independent purchase of plastering materials will cost much less.

Finally, the last of the best, judging by the reviews of the samples, is a car from Russia.

"Afalina" (Russia)

Afalina stations are universal. They are intended not only for plastering walls, but also for pouring floors, as well as treating ceilings. The functionality and power are at the same level as their foreign counterparts, but there is one important difference - size. So, the Afalina cars are much larger. This causes some difficulties when working with it: more people are needed to service it.

Due to the fact that the machine is more labor-intensive to maintain and operate, and the price is not much inferior to foreign models, hiring a team working on such equipment is usually more expensive than paying for the services of a company with foreign stations available. Therefore, this sample is not very popular, and it can be found quite rarely.

But the quality of mechanized plaster made using this unit does not suffer.

Application methods and technology

When carrying out work using a special plastering machine, you must adhere to a certain sequence of actions.

First, the walls need to be cleaned. Experts advise using a special metal brush.
Next, the base needs to be wetted. This is done using a primer or plain water.
Then they begin to prepare the equipment: connect it in accordance with the instructions, adjust it to the existing plaster composition.

Now you can proceed directly to the application itself. Classic way– applying the composition from top to bottom in stripes, when each new strip is applied so as to half cover the previous one.
If possible, you can use the bottom-up method. The overlap of the strips should be the same.
After the solution has set, it must be smoothed with a construction mesh float.
When the solution is completely dry (the hardening time is indicated on the packaging), you can proceed to subsequent finishing: for example, puttying the walls or painting.

Experts give some advice regarding the selection and use of mechanical plaster.

Pay attention to the uniformity of the composition. There should be no lumps in it.
Under no circumstances should you purchase plaster for mechanical application if it is intended solely for manual use.
All work must be carried out at a temperature from +5 to +30 degrees, otherwise the mixture will change its technical characteristics.

You can clearly see the process of mechanized plastering in the video below.

For machine plastering of surfaces, machine stations are used, manual machines. These devices can be based on different operating principles, which affects the speed and efficiency of their operation. In the article we will look at the details and features of the mechanical plastering process.

Mechanical plastering of walls

Finishing walls and ceilings through plastering can be a costly process that requires manual labor.

However, it is possible to simplify and speed up the process of performing such an operation by using a mechanized method. It involves the use of specialized equipment that will result in a flawless surface.

Peculiarities

One of the main features is that some modern devices make it possible not only to carry out the plastering operation, but also a number of preparatory work on surface treatment. In some cases, this makes it possible to eliminate or minimize the need for manual labor and the use of small-scale mechanization equipment.

What equipment is offered for automated plastering?

There are only two basic principles of machine application: jet and mechanized. In addition, the jet type is divided into two more categories: screw and pneumatic.

Installation of pneumatic hammer: machine for applying plaster using a mechanized method

A pneumatic hammer or pneumatic shovel is equipped with several nozzles that are designed for hard and soft solutions. The device consists of:

steel container for scooping the mixture;
four nozzles for supplying the composition;
four nozzles for air supply;
tube holder with a built-in valve for supplying and adjusting compressed air.

Automatic pneumatic pistol

A pneumatic gun for automatic plastering is a short nozzle barrel, which is equipped with threaded connection for installing various attachments. Depending on the type of nozzle used, the degree of spraying of the mixture and other parameters are determined.

At the top of the machine there is a container for the mixture, usually five liters. The device is also equipped with a trigger that controls the supply of plaster. A hose for supplying compressed air is inserted into the lower part of the gun, into a specially provided hole.

Is it possible to make wall leveling equipment yourself?

You can make a homemade unit for plastering walls yourself; according to the principle of operation, it will repeat the spray gun, which is powered by a compressor.

A cut fire extinguisher is taken as the basis for the device, so that a container of four to five liters is obtained. Next, a tube with a nozzle is inserted inside to supply air with a diameter of four millimeters directly into the outlet of the fire extinguisher. The power of the device is affected by the diameter of the outlet nozzle, as well as the size of the gap from it to the compressor valve.

What kind of compressor should be for the device?

The compressor for the station must be good and pump air quickly. His main task is to create and maintain an operating mode at a pressure of two to three atmospheres.

Pros and cons of plastering with stations for leveling walls by machine

When considering the issue of the machine method of plastering surfaces, it is necessary to separately analyze the advantages and disadvantages of this method.

Among the advantages are:

High labor productivity.
The ability to ensure a strong connection between the plaster layer and the base.
Possibility to significantly save plaster.

Disadvantages include:

The need to purchase an expensive station, rent it, or hire a crew.
It is necessary to ensure sufficient and uninterrupted supply of power and water.

It takes up to five days for a fresh plaster layer to dry, and the temperature range in the room should be maintained between 5 and 30 degrees.

Automatic gypsum machine plastering of walls: which machine is suitable

Automatic gypsum machine plastering is the process of applying a leveling and decorative layer to a previously prepared surface using specialized equipment. To perform such an operation, one of the main types of devices is suitable:

pneumatic shovel;
air gun;
plastering machine.

Each of the devices is characterized by its own characteristics, properties and principle of operation.

It is extremely important to apply the layer of plaster evenly, evenly and quickly. Only a trained and experienced specialist can effectively handle such a task.

How to apply plaster to ceilings and walls

The working process of applying plaster by machine is divided into stages.

First of all, preparatory measures are carried out in the room where the work will be carried out. Accordingly, at this moment, wiring and other hidden communications are laid, and then beacons are installed.

In parallel with the preparatory activities, the plastering station is set up, which, as a rule, has a three-phase motor and does not work, without special permission, from an ordinary home network. Water can be supplied to the station from a water supply pipe or a reservoir of sufficient volume. A high-quality plaster composition with good strength characteristics is prepared inside a plastering station. Traditionally, a proportion is used where there are five liters of water per ten kilograms of dry mixture. The mixture is prepared in an airtight container. After the mixture has been prepared, the main work process begins. After setting up and starting up the equipment, the mixture is supplied under pressure through a pressure hose, and then applied to a previously prepared surface using a special gun.

The speed of applying plaster is quite high, which makes it possible to carry out large volumes of work in short terms. Thanks to special thickener additives, the mixture does not spread over the surface of the ceiling or walls.

To ensure proper operation plastering station and an impeccable result after the operation, it is recommended to use only specialized mixtures.

Work on applying the plaster layer begins from the corner of the room, moving further between the beacons. After the mixture has been applied, it may in some cases be necessary to manually level the layer and then grout.

The article discusses information about the details and features of the mechanical plastering process, as well as its advantages and disadvantages.

Plaster is the most relevant in the field finishing works. It is usually applied by hand and requires a lot of time and effort. IN modern world Machine plaster is becoming popular, which is applied to the surface using specialized equipment called a “plaster station.” The question arises - what is better?

Some people tend to believe that manual plastering is a more controlled process than mechanical plastering. It follows from this that the quality of hand plaster is better. However, this is not true. To be confident in your choice, you need to understand the features of these two types of plaster.

Using manual plaster on beacons, the mixture hardens very quickly and the process itself is very long. Accordingly, the solution has to be made in small portions, which only complicates and increases the work time. In addition, using a solution of the same consistency on a large surface is quite difficult. Following the experience of specialists, you must first apply a layer and then level it, which subsequently leads to uneven drying, and subsequently the formation of unevenness and cracks.

High results can be achieved when choosing the method of machine plastering:

reduction of work time (3-5 times on average). With the continuous process of making the solution and applying it to the surface, as well as by reducing the number of layers. The mixture can be applied in a thicker layer, which allows you to quickly eliminate unevenness;
The plastered surface is almost perfectly flat, the solution is supplied under pressure. As a result, this plaster has no voids, which means the risk of cracks or peeling is reduced;
Even though the surface plastered in this way requires grouting, such an operation is much simplified, since often the quality of the finish is quite suitable even for wallpapering walls. Often, mechanized plaster for painting is used as a base layer for facade work, which reduces their cost and, no less important, without loss of quality;
due to the fact that a thicker layer of mortar can be applied by machine, as a rule, it is possible to level the walls immediately, which is not possible with manual version leveling walls with plaster;
Less materials are required due to the fact that during the production of the solution it is actively enriched with air, due to which its volume increases. In addition, it should be taken into account that manual plastering will have to be done in at least 2 layers, and this leads to additional costs;
machine stations are used not only for wall decoration. With their help, “fur coats” are sprayed, self-leveling floors are created, and screeds and cement concrete are installed.

In most cases, machine-applied gypsum plaster is used for interior work, so it is quite possible to talk about the environmental friendliness of this method, since this material is quite safe and highly vapor-permeable.

There are very few disadvantages of the mechanized surface treatment method:

High prices for the purchase of machine installations. The benefit is that the use of the equipment is relevant for large rooms.
Constant maintenance is required.
Cleaning hoses from residual solution.
Noise when machines are running.

If you still have doubts about what type of plastering to choose, then there is still an argument for choosing the machine method. The mixture for this type of plaster is cheaper. When calculating the estimate, the cost of labor and materials is included, and there is no need to hire a large team. I note high quality work does not eliminate the need for putty under the wallpaper of the plastered surface.

Manual or machine plastering - using both methods requires special skills, so to achieve high results It is better to entrust the work to a specialist. For small areas manual processing would be appropriate, and if we talk about repairing the entire room, then the machine plastering method is completely justified.
