A device for applying plaster with your own hands. A plastering machine is a faithful assistant for any finisher

Finishing walls with leveling compounds is not always successful, especially when done by a beginner, which is why it is increasingly used today plastering machine, allowing you to feel confident in the strength of the coating. Exist different variants, automatic and mechanical, which still require some labor, but all units are similar in one thing - the result is always better than manual finishing. The main thing is that the mechanism masters the task assigned to it.

What kind of machine should a plastering machine have?

So, we are well aware that mechanized labor is many times more efficient than manual labor, but how can you find out what exactly that unit was that you needed so that finishing work could be carried out in as soon as possible without much difficulty. Perhaps, it is possible to determine how suitable a machine is for applying plaster in your particular case only in a practical way, but we will try, at least in theory, to derive the formula for an ideal mechanism. However, again we will proceed from different requirements.

Let's start with simplicity. In other words, the unit should be extremely easy to operate so as not to cause difficulties and, especially, errors for a beginner. The most primitive types of machines that meet this requirement can hardly be called technology; rather, they are improved tools. They are a hopper with a rectangular hole in the front (by the way, the only one), a handle at the back and a rotating handle (like a meat grinder). Inside there are brushes mounted crosswise on the shaft. By pouring the mixture inside and rotating the mechanism, we obtain uniform spraying of the plaster over the surface. A sort of improved grandfather's broom with a stick.

Small dimensions. This requirement significantly narrows the search sector, since bulky plastering stations are immediately eliminated. To a greater extent, pistol sprayers with a hopper in the upper part fall under this definition. They have different names, depending on the manufacturers and sellers; there is no standard name as such. The most commonly mentioned are crumb sprayers or hoppers. Their design is very simple: a compressor, a hose, a nozzle with a hopper and a nozzle. The supply of the mixture to the surface to be treated begins after pressing the release lever.

Apparatus for plastering walls in large quantities

Sometimes the upcoming finishing work seems overwhelming: huge areas of surfaces that need to be covered with a leveling mixture and the absence of other assistants except own hands. In such cases, priorities in choosing equipment change dramatically, and productivity comes first. It would seem that it’s time to rent the same station that was mentioned above, but if you compare the financial costs of it and labor costs in the absence of automation of the process, it’s more profitable to just pick up a spatula and gather your courage.

It is convenient when the unit not only supplies the mixture to the wall, but also prepares it in its hopper, but performing a one-time job using the station will increase the price of the plaster to the level of gilding. Therefore, we choose what is simpler. And at the same time more efficient. Let’s immediately decide on the type of mixture supply. If it’s pneumatic or mechanical, the station is in front of you; if it’s gravity, that is, under its own weight, then the search was successful and you found the hopper. All that remains is to choose an option with a bunker that is spacious enough and at the same time not too bulky. Agree, a container with 15 liters of plaster will be difficult to hold in weight, but 5-7 liters will be just right.

In addition to the capacity of the tank, you need to pay attention to such little things as the material (it is better to choose metal, it is stronger, although heavier than plastic), as well as the packaging. Very often, in addition to the gun, replaceable nozzles are supplied, the diameter of the holes of which determines the possibility of using mixtures with different grain sizes, the thickness of the jet and, accordingly, the density of the layer. Thus, the apparatus for plastering walls can be used for solutions of different consistencies without the need to bring them to a common denominator by diluting or, conversely, fixing them with fillers.

Homemade apparatus for applying plaster

If you have a workshop and there is no shortage of tools, you can try to save even more money and make the unit you need for wall finishing yourself. And as a blank, let’s take... a fire extinguisher, the cylinder of which has everything you need: a handle, a release lever, a nozzle. All we have to do is remove the bottom, since we will hold the future sprayer with the nozzle down, and the rest of the part will become an open hopper at the top. The only addition that is required is an air supply tube cut into the wall of the cylinder opposite the outlet hole.

In addition to the diameter of the nozzle, the jet power is also affected by the distance to it from the compressor nozzle. Therefore, we push the air supply tube as deep as possible, so that there is a gap of no more than 20 millimeters to the outlet hole (the smaller, the stronger the ejection of the mixture). Do without welding work(if the air duct is metal) can be done by filling the insertion area with resin from the inside, placing the fire extinguisher at an angle of 45 degrees to the ground, with the nozzle up. In this case, the resin will harden in shape inclined surface, ensuring smooth sliding of the mixture to the compressor tube. The main thing is to try not to clog the outlet.

All that remains is to purchase air compressor, connect the hose to the nozzle embedded in the former cylinder and create a pressure of a couple of atmospheres. With this mode of operation, the finished surface will be rough, under " fur coat“If you apply higher pressure, the mixture will apply more densely, creating a smoother coating. The diameter of the air duct nozzle also plays a role in the formation of the jet, so it is advisable that it does not exceed 4-5 millimeters. The apparatus for applying plaster is ready, you can “charge” it with the mixture and “fire” the prepared surfaces.

How to use a spray hopper

The first and most important thing is a correctly made composition. For machines that perform plastering work, the consistency that is convenient for applying it with a spatula is not suitable. Instead of water, it is better to knead the mixture with lime milk, this will make it more durable.

Plastering work is one of the most difficult repair jobs. Equipment for plastering surfaces allows you to get rid of manual labor when performing complex operations. You can buy a ready-made plastering machine, and if you want to save money, make it yourself.

Will one machine replace a team of construction workers?

The main advantage of using technology is freedom from routine manual labor. True, a machine cannot completely replace a person, but it greatly facilitates and speeds up the process. There are a number of advantages that speak in favor of using specialized equipment:

1. Preparation of plaster mortar requires an exact ratio between dry mixtures and water. If a person can make a mistake, then the machine, observing the exact dosage, prepares high-quality mixtures automatically.
2. Mixing of mixtures is carried out mechanically. It is difficult for a person to mix the solution; it takes long time. The machine kneads quickly. Thanks to the accelerated supply, the solution contains a large amount of air, which makes it possible to save money, since at the same cost, more solution is obtained.
3. One plastering unit can replace an entire construction team. In this case, the process proceeds much faster, and evenly applied thin layer the solution dries better.

This means time is saved and less material is consumed. A high-quality and durable coating is created that does not require puttying or further finishing work to level the surface. The equipment is easy to operate. The operating rules are described in the instructions included. Therefore, a person of any training can work with the device. The dimensions of the machine are small, special handles and wheels make it easier to transport the equipment to the work site.

The unit consists of separate modules, which makes it possible to assemble and disassemble it for transportation over long distances and storage. Serial machines have the ability to adjust work processes, so they can be used both on large construction sites and for small volumes of work.

How the miracle unit works and how to choose a solution

For uninterrupted operation the device requires constant access to electrical network. In certain circumstances, running water is also required. If it is not available at the construction site, serial devices are equipped with a pump that allows you to pump water from any container. To mix the mortar, plastering units are equipped with special bins into which dry mixtures are poured. Ready-made mixtures coming from the plant are also loaded into them.

After the bunker, the mixture enters a special chamber using a screw method, where it is mixed with water. The process occurs continuously. The finished solution is immediately supplied through the solution hose to the distribution system. At the end of the hose there is special device for applying plaster - usually it is a gun. With its help, the solution is applied in an even layer required thickness. Plaster guns support several application modes. The choice of mode depends on the consistency of the solution and the type of working surface.

Solutions that are used for machine application have the following features:

short drying time;
quickly gain strength;
good adhesion to the surface being treated;
good heat and sound insulation characteristics;
high vapor permeability.

If the mixtures are applied using an automated method, their characteristics are improved, which makes it possible to create an optimal microclimate in the room.

To level the walls of buildings from the outside, a regular cement-sand mortar is used. For residential premises (living rooms, bedrooms, children's rooms) are used gypsum plasters. For rooms with high humidity(kitchens, bathrooms) we recommend taking mixtures based on acrylic resins, or in which they are used polymer additives. Ready-made solutions are supplied already diluted with water, they can be immediately applied either by machine or manually. Modern mixtures contain substances that increase the plastic and astringent characteristics of the finished solutions.

Plaster shovels, guns and machines - which equipment to prefer?

For automatic application of solutions, special plastering units are used. Since this is expensive equipment, its purchase is economically justified for performing large volumes of work. For one-time use, it is more profitable to rent equipment. There are several types of devices for mechanized surface treatment.

A pneumatic shovel for applying solutions to walls and ceilings is a metal container for the finished solution, equipped with four nozzles for supplying air and four for supplying the mixture. The diameter of the nozzles depends on the type of solution used. The plaster is supplied to the surface through a special pipe. The tool has a valve that regulates the supply of air under pressure. On average, up to 60 can be processed in an hour square meters. Different models of pneumatic shovels are used for plastering ceilings and walls. They differ in the location of the container with the solution relative to the tube through which the supply is carried out.

The air gun is equipped with a nozzle barrel with threaded connection, onto which the nozzles are screwed. Differences between nozzles - in the degree of spraying plaster mixture. The container with the solution is located at the top of the unit; it is made of metal or plastic. The volume may vary, but is usually about 5 liters. The supply of solution is controlled using a trigger. At the bottom of the gun there is a hole for connecting a hose through which compressed air is supplied. Thanks to the nozzles, you can use solutions of different consistencies and spray the mixture with varying degrees of intensity. This feature of the gun makes it possible not only to perform rough plastering of the surface, but also to apply the finishing layer.

Plastering machines are presented on the construction market various models, differing in equipment, dimensions, performance and price. The middle class plastering machine has small sizes and can be operated by one person. The main component of the device is a pump that ensures the preparation, supply and spraying of the solution onto the surface to be treated. Grain size of mixtures for aggregates similar type should not exceed 2 mm. Depending on the design, some machines are equipped with separate containers for dry composition, water and mixing. The process of obtaining the solution is completely mechanized and is specified special program. This makes it possible to obtain a high-quality mixture with precise proportions without air bubbles and lumps.

We make our own unit from a fire extinguisher - according to the principle of a spray gun

If purchasing a ready-made plastering unit is unprofitable, you can save money and make an application unit. The basis of such a device is a fire extinguisher with a cylinder of about 4 liters. This blank has everything you need to create a machine for spraying the mixture: a nozzle, a handle, a lever that opens a hole at the outlet.

First of all, it is necessary to cut off the bottom, since in the future the device will need to be held with the nozzle down. A cylinder with a cut bottom plays the role of a bunker. The only thing you need to add is homemade sprayer– this is a tube through which compressed air will be supplied. It should be cut into the side wall of the cylinder opposite the valve outlet through which the mixture is sprayed. The device works on the principle of a spray gun. Compressed air is supplied from the compressor. For high-quality spraying, the nozzle diameter should not exceed 4-5 mm.

For power homemade device the following factors influence:

nozzle diameter;
distance between the nozzle and the compressor nozzle;
supply air pressure.

To increase the jet power, the air supply tube must be brought as close as possible to the outlet valve. If plastering is done “under a fur coat,” then the distance should be no more than 1.5–2 cm. For finely dispersed solutions, the distance should be reduced even further. The smaller the gap, the more powerful the jet will be. It is important to increase the pressure.

You can secure the tube using nuts with sealing gaskets, then it is easier to adjust the distance, and the connection must be welded. There is another option without using welding machine– fastening with resin. This way the tube will not only be secured, but also sealed. To do this, the tube must be fixed at an angle of 45 degrees with the axis of the outlet hole and with the ground. The resin is poured in liquid form so that the final level is below the nozzle. Filling with resin is advantageous in that the liquid flows down the inclined tube to the nozzle evenly. Care must be taken to ensure that the outlet is not clogged. Then you need to wait for the resin to harden.

On final stage The air compressor is connected via a hose to the nozzle hole. To operate the device, create a pressure of 2 atmospheres. With a little pressure, the finish turns out to be rough, suitable for “a fur coat.” A smoother coating with filling of all pores is obtained with more high blood pressure.

The right technology + a good device = a perfectly flat wall

Before finishing work begins, the working surface requires preparation. The surface must be cleaned of remnants of the previous finish. There should be no damp or oil stains on it. If there was fungus and mold on the walls, mandatory treatment is necessary by special means. The prepared surface must be smooth, strong and dry. Apply primer to the finished work surface. When the coating has dried, you can begin plastering.

First we prepare the solution. It is better to dilute the dry mixture with milk of lime rather than water, then the coating will be more durable. Divorced cement-sand mixture standard: 1 part cement and 3-4 parts river sand. The solution should turn out like thick sour cream, it should not be too liquid. At the final stage of mixing, we add plasticizers to increase viscosity. If you use factory plastering equipment, then an instruction manual is attached to it. Before work, check that the hoses are not kinked. Using homemade apparatus the sequence of actions is as follows:

1. Fill the container 2/3 full with the solution.
2. You need to stand at an angle to the surface being treated. The dominant hand holds the gun, and the other holds the hose. The hose should be long enough for free movement along the wall.
3. Press the trigger lever only when the gun is pointed at the surface. The distance from the surface to be treated to the nozzle is at least 30 cm.
4. The jet should make an angle of 90 degrees with the wall surface. When plastering the ceiling, direct the jet at a slight angle away from you, applying the solution in a thin layer.
5. We begin applying the mixture from the corner, first filling the cracks and depressions. We apply stripes about 70 cm wide.
6. Apply each subsequent layer after half an hour, especially if lime is present in the solution.
7. The number of layers depends on the thickness of the plaster that needs to be obtained.

The process of applying plaster is quite labor-intensive, and a person who is faced with such a task for the first time will spend a lot of time, but may not get the desired result.

A special plastering machine will help you do everything much faster and at the same time much better.

Because the appearance home creates the first impression of the owners, then most want to make it ideal and unique. This is one way to bring an idea to life.

But, as already mentioned, this process is quite labor-intensive because it includes many stages: mixing the solution, applying it, leveling, rubbing. Plastering machines will make this job easier and will make everything much better.

You can list the advantages of using them for a long time, but still:

you can work to apply the solution inside the house and for facade finishing;
the surface turns out to be almost perfectly flat, but it’s very difficult for a beginner to do this, and even to an experienced master not always possible;
can prepare a solution without lumps and other inclusions (not all models have this function);
quickly complete a certain amount of work;
there is no need to additionally sand or putty the surface if it is not prepared;
the level of adhesion increases due to the high pressure under which the solution is supplied. This helps to increase the service life of the applied layer;
the amount of materials that the machine uses to apply plaster is significantly less, since there is no need to repeatedly eliminate defects in the work.

Despite all the positive aspects of using such a device, there are several disadvantages that you need to be prepared for:

if you choose large devices, then their weight is very large and movement requires the strength of several people;
some devices use more power than the standard 220 V, in which case another phase must be connected;
you need to work quickly, since the prepared solution hardens within 30 minutes, and the residue in the hose will ruin it;
large models are quite noisy, with internal works V multi-storey building, you need to first agree with your neighbors;
large-sized devices are washed with large quantities of water up to 30 liters.

Types of devices

All plastering machines are divided into three types:

Plastering stations. It's bulky professional models. Almost all the work is done without human intervention; you just need to rearrange them in time. There are stationary options, they can only be moved using a crane, and mobile (mobile) - there is a convenient chassis with which the device moves.

Pneumococci and pneumatic pistols. Such machines for plastering walls have significantly smaller dimensions. Convenient for home use, the solution must be prepared in a separate container.

Mechanical models. Some craftsmen call such devices “hurdy-gurdy” because in order to apply the solution to the surface you need to rotate the handle on the body. These are the most popular and simple devices for self-application plaster.

How the machine and its structure works

All plastering machines consist of:

engine (power ranges from 0.5 to 1 kW, depends on the purpose of the device - for applying plaster to the facade it is better to choose a more powerful one);
solution tank;
hose and sprayer;
compressor.

Essentially, all devices work the same way: whether they are huge plastering stations or small hand-held pneumatic guns. The dry mixture and water are loaded into the tank if these are professional plastering stations where the mortar is mixed. In this case plaster mortar It turns out to be of very high quality, without any lumps, the master himself regulates the density.

But there are models that can themselves set the amount of liquid to a certain weight of the mixture to obtain the ideal consistency. Such machines have electronic controls and must be connected to a central water supply.

And there are those who do everything completely themselves, just stand there and watch.

If this is a small unit intended for home use, then the prepared solution is placed in the tank. The compressor pumps air into the tank, and the solution is applied to the surface under pressure through a nozzle. At the same time, the person regulates the amount of solution that is applied to the wall, moving the hose from side to side and gradually filling the entire wall.

Safety precautions

In order to avoid unforeseen situations, when working with a plastering machine, as with any electrical appliance, you must follow the safety rules:

people need to wear protective glasses and suits to protect them from small particles coming into contact with the mucous membranes of the eyes and skin, which may be in the liquid solution;
the hose must not be directed towards a person;
For work, use only special mixtures without dyes;
the sprayer must be held perpendicular to the wall;
in order for the solution to be applied efficiently, the air temperature must be at least 5 degrees;
If the device is turned on, you should not clean the channels, add solution components, or carry out repair work.

How to apply plaster with a device

Before applying the solution to the wall, you must prepare the surface:

Remove old coating, if any.
Remove nails and fill holes.
Apply a layer of primer and wait for it to dry.
Install reinforcing mesh and beacons if necessary.

After this, you need to prepare the plaster solution either in the machine, if there is such a function, or in a separate container and load it into the tank. After which the nozzle is directed to the upper left corner of the wall and open the valve.

You need to apply the plaster to a section no more than 65–70 cm wide, and then go down to the bottom row, making sure to cover the previous one by a few centimeters (up to 10). The slower the master moves, the thicker the layer is applied to the wall; this must be taken into account.

The entire plastering process must be carried out by two people. While one is applying a layer to the wall, the other, using the rule, evens out the applied layer until it has completely hardened. If suddenly there are voids left on the surface after leveling, you need to add a solution from a hose and go through the rule again.

Often in the corners or at the junctions of the ceiling and wall, minor defects appear. They are removed using a regular spatula. After all the walls have been treated, the machine for applying plaster must be disassembled and washed thoroughly so that the remaining solution does not clog the channels and the device lasts as long as possible.

A video on how to apply plaster with a manual machine.

Where is a plastering machine used?

With this device you can easily plaster not only the walls inside or outside the house. It also performed well when leveling the ceiling, where it is much more difficult to carry out already complex work.

The plastering machine can also be used for:

applying gypsum and cement mortars;
thin-layer plaster;
priming and putty;
creating a self-leveling floor;
painting works;
cement concrete screed.

How to make a machine with your own hands

You can make a device for applying plaster yourself, if you have the desire and opportunity. For this you will need:

old fire extinguisher;
compressor for air supply;
hose and tube.

A fire extinguisher cylinder is perfect because it has a handle, a release lever, and a nozzle. All you have to do is remove the bottom. Such a container must be held upside down, so the solution will be supplied from above.

You also need to make a small hole opposite the nozzle and secure the air supply tube there so that it is at a distance of about 2 cm from the outlet hole. The smaller the gap between the tube and the nozzle, the more the solution will be ejected.

You also need to pay attention to the nozzle itself. It is advisable that its diameter does not exceed 4–5 mm, in which case the highest quality jet will be formed.

Next, you need to connect the compressor using a hose to the tube and the device is ready. If you create a little pressure, the layer will be quite rough, but with increasing pressure you will get a smoother surface.

The prospect of hand plastering hundreds, or even thousands, of square meters of walls may seem promising to few people. Equipment has been developed specifically for such cases, optimizing the difficult work of the finisher.

Options for replacing manual labor with machine labor

applying plaster. Under influence compressed air from the compressor through a gun or pneumatic bucket;
mixing the solution. In the simplest case, we are talking about using a hammer drill with a mixer attachment or a special construction mixer. For professional purposes, special machines are often used for mixing plaster;
application and delivery. It involves the use of a machine that combines the properties of the first two options for mechanization of wall plastering

Using a plastering gun and pneumatic bucket

To mechanize the process of applying mortar to the wall, the so-called pneumatic bucket or cartouche gun for plaster can be used. They are designed quite simply: a container for the solution and locking fittings. The container has a hole for a nozzle through which air is pumped, and an outlet through which the plaster mixture is applied to the surface under pressure. As the container is emptied, it is filled with freshly prepared composition.

The possibility of thin spraying of solutions is in demand when using decorative plasters.

A special feature of the pistols is the ability to vary the size of the nozzle: with a diameter of 4, 6, 8 mm. This allows you to more accurately control the thickness of the applied layer of solution. While regulation of the operation of the buckets is possible only by changing the distance between the device and the surface being processed.

The installation includes:

compressor of calculated power required for air injection;
a hose through which this air will be supplied to the device for applying the solution;
a gun or pneumatic bucket, the design of which ensures the release of plaster under the pressure of the air supplied to it. To regulate the operation of the devices there is a locking mechanism

How much does it cost and is it worth it?

Don't be under any illusions - using these devices is not as simple as it might seem at first glance. Think for yourself, after all, you will constantly have to hold a tank with a capacity of up to 5 liters, filled with plaster, in your hand: moving it back and forth at different levels is not always a pleasure. Obviously, the whole process will be varied by periodically filling the tank with the mixture, as well as leveling the fur coat.

Approximate prices for devices for applying plaster mixtures

The video below clearly shows the use of a pneumatic bucket for wet finishing.

Well, here you can watch the process of spraying (literally) the plaster mixture using a gun.

Are you satisfied with this technology? If yes, then you know what to do!

Plastering walls using professional stations

Such machines are units that are used to mix, feed and apply the plaster mixture to working surfaces. For these purposes, they are equipped with a special hopper for preparing the solution. From here, air from the compressor supplies the plaster through a hose to the sprayer. Stations differ in productivity, delivery range, and maximum pressure (feed height).

More often, ready-made products are used as raw materials for the solution. gypsum mixtures, many of them specifically designed for machine application. But that's what concerns interior decoration- For facade works any suitable solutions may be used.

Typically, the loss of mortar with this method of plastering walls is minimal. But not in the case of the hero of our photo.

Ideally, 3 people (usually 1-2) should be involved in the process: one monitors the preparation of the solution and the operation of the machine, the second is assigned the task of applying the solution in the form of a fur coat, the third smoothes the plaster along the beacons, using the rule. Here, the requirement for continuity of work is very important, at least until the next batch of the mixture is processed. Otherwise, problems may arise with the solution frozen in the installation - there will be a lot of problems here.

Advantages

High finishing speed. This is one of the most important advantages of using special plastering stations. Some teams promise to finish 150-200 m2 of walls per shift.
+ In a minimum period of time, a large surface can be treated - in contrast to the uneven application and drying characteristic of manual plaster.
+ In general, the cost of such work is lower than when using non-mechanized methods - due to lower labor intensity.

Flaws

– A focus on increasing productivity can play a bad joke with the customer, because... Quality with this approach can significantly decrease. Preference for this finishing method is given mainly when working in office buildings, when the object for rough finishing needs to be completed as soon as possible.
– The use of plastering stations implies a continuous type of work in non-stop mode. Otherwise, the solution may harden inside the installation, form plugs and cause equipment failure. Therefore, in case of power outages, they prepare an autonomous liquid fuel generator - its presence is 100% justified.

Let's talk about prices

Compared to the manual application method, using machine plastered walls allows you to save a lot. But you need to take into account that this is possible under the condition of a large amount of work. The relationship here is direct: the larger the total area of the walls at the facility, the more noticeable is the minimization of costs for finishing work. Below we have presented average market prices for such services.

If you plan to save money on the work of specialists, but still prefer the machine method to manual plastering, then necessary equipment can be rented. The cost depends on the specific station, but usually it varies between 1300-2000 rubles/day. Companies that offer rental services for machines for plastering walls usually set a minimum rental period of 14 days. You will also have to pay a deposit and voluntarily and compulsorily sign up for paid commissioning and instruction. Naturally, the delivery of equipment lies on the shoulders of the customer.

Do you have plans for serious finishing work? Then it makes sense to buy new car for plastering walls. Subsequently, you can rent it out, sell it, or become a professional plasterer.

That's all we wanted to tell you about modern methods wet finishing. Now, depending on your priorities, you can choose between machine application and manual application. Unfortunately, in both cases, much depends on the qualifications of the workers - human factor no one canceled.

Any repair is not complete without auxiliary means and large quantity various building materials, as well as equipment. The use of such improvised means greatly reduces work time and saves energy. Thanks to various techniques and repair tools are much easier and more convenient to work with, and the quality of the work performed increases.

Important assistant

Modern developments in the field of construction equipment have made it possible to significantly simplify and facilitate the work of builders. One such mechanical assistant is an automatic plastering machine. with internal and external have great importance: they are the most painstaking and time-consuming, and the result must literally be obvious.

Mechanization of the finishing process allows us to reduce work time and minimize the costs of using human resources. In the construction of large-scale projects, these conditions are basic, since instead of a whole team of workers, you can get by with one or two people. And this, in turn, significantly affects material costs.

Description of equipment

A device for treating walls is a unit, the structure and principle of operation of which are quite simple. The cars become Lately more and more popular. This is due to a number of advantages:

Easy to use.
Speed of completion of any finishing work.
Technical reliability.
Versatility: the ability to apply dry and wet plaster mixtures.
Layer uniformity.
Capable of covering large areas.

The plastering machine is practically indispensable for large-scale construction and repairs. Plaster the walls by hand production premises future factory or high-rise office buildings or apartment building It's hard enough. This will be long and difficult even with the most experienced team of plasterers.

In addition, you can use equipment that already works ready-made mixtures. In this case, the machine will be cheaper, since there is no hopper for preparing the solution.

Principle of operation

The plaster, which is applied using such a mechanism, is distributed and laid more evenly and accurately. This significantly simplifies and shortens the period of repair work. It is necessary to ensure that the equipment has access to the electrical network. Sometimes it will be necessary to provide special conditions, since industrial modifications with a power of 380 rather than 220 W are quite common on sale. In addition, a source of water supply is needed. If there is no running water, you can use any container with water; the kit includes a special pump for its forced supply. The machine calculates accurately required amount water and dry mixture. This allows you to obtain a high-quality solution at the output.

The standard hose length allows you to process surfaces up to 5 meters high. Eliminates the need to use scaffolding, as in the case of manual work.

The quality of the mixture used for wall finishing also influences the result of finishing work. It will be easiest and most convenient to use gypsum mortar. It is adapted specifically for machine application, unlike cement-sand. The first option also has a number of advantages that have a positive effect on the results of work in which a plastering machine is used:

Environmentally friendly material.
Quality product.
Does not require subsequent putty.
Surface whiteness.
Quick drying of the wall.

Gypsum plaster allows moisture and air to pass through and maintain a natural microclimate in the room.

Stages of work

In any construction or repair work preparation is important. She is half the whole story. The future working plane must be well cleaned of old layers so that the surface of the wall or ceiling is ready for finishing.
It doesn’t matter which method is used for plastering, the surface must be smooth. To do this, beacons are installed that measure curvature and level the surface level horizontally and vertically.
Installation of profiles for processing corners.
Applying primer.
The plastering machine is equipped with a special tank in which the mixture is prepared for subsequent application to the dried primer.
Applying the mixture with a technical gun, which distributes it evenly over the wall.
Leveling and distributing the solution according to the level of the beacons, adding it to those places where it is missing, and removing excess.

The plastering machine helps to complete each stage consistently and accurately. Applying the solution should start from the corner to the center. It is better to make stripes less than a meter wide. After completing each stage, the wall surface must be covered with film, which is then cut off. Such recommendations are left by the manufacturers of equipment and materials themselves.

Wall surface treatment

This stage is important and final in plastering. By the way, it can also be much faster and easier. A plastering machine can help with this. This usually happens with a sponge and water. But in this case, the equipment practically does its job itself, which is especially convenient for large finishing areas. The surface is completely suitable for painting or wallpapering. In addition, the final result also depends on the class of plaster. It is different for different rooms.
