Homemade plastering machine for applying a “fur coat”.

Over time, everything is destroyed, and no matter what grandiose buildings there are, time erases them into dust. True, they are still worth it Egyptian pyramids, but time will scatter their ashes over the desert. These were the philosophical thoughts that flowed in a slow stream in my head as I looked at the peeling plaster of my house. It was clear that the amount of work would be large, and he turned out to be right - when he began to shoot down old plaster, it began to move away from the wall in layers. A couple of days later I looked with quiet horror brick wall, and I realized that if I don’t come up with anything to help myself, then I’ll be plastering just before Chinese Easter. I’ve been plastering for a long time, but I didn’t have to apply a “fur coat”, I looked up this topic on the Internet, but it was suggested to wave a broom (old old-fashioned method), and I brushed it aside. When I entered the garage, a spray gun caught my eye, and I decided to make a plastering machine using the same principle, powered by a compressor. I took a fire extinguisher as a basis, cut it, it turned out to be a 4-liter capacity, inserted a tube with a nozzle (d4mm) inside, the outlet hole in the fire extinguisher was 10mm, the distance from the nozzle to the outlet was 15-20mm. As they say, I assembled it on my knees, installed what was at hand, but if you have a turner nearby, you can order nozzles of different diameters - 3mm, 4mm, 5mm. The machine went off with a bang, four liters of solution flew out in 50 - 55 seconds, covering almost a square meter. It took more time to prepare the solution; by the way, the solution was made 1c to 2p, and filled with lime milk. I tried making the solution both thinner and thicker, but I liked the second one better - it fits the fur coat perfectly.

I would like to apologize for the low quality of the video, you could say I filmed it with the Lumiere brothers camera: request. and therefore the texture of the plaster is poorly visible.

Apparatus for applying plaster: features of use

A plastering machine for mechanical finishing of walls helps a person get rid of heavy manual labor. This is especially important when performing repair work on a large facility. a short time. Plastering with a machine is a process of leveling walls with special mixtures. It allows you to replace doing the work yourself with mechanical method, while preparing the mixture and applying it to the surface.

Features of mechanized plaster

If when working manually:

  • The mixture needs to be prepared in small portions due to its rapid hardening, in about 50 minutes.
  • Operations are slow.
  • Even a fairly experienced plasterer will not be able to prepare a solution of the same consistency every time.
  • It is impossible to apply the mixture simultaneously to the entire surface:
  • the solution is mixed;
  • throws himself on the wall.
  • As a result, part of the wall practically dries out, the second part dries out, and the third part is only covered with mortar. The result is a scaly surface, which can lead to unevenness and cracks over time.

    Unlike the manual process, the mechanized one allows:

    • Apply coating quickly and evenly.
    • Get more high-quality finishing surfaces.
    • Save solution - much less of it is used. This is due to the fact that when the unit stirs, the mixture is saturated with air, which increases the volume of the solution.

    So, when manually plastering the finishing of one square meter area requires approximately 16 kilograms of solution, and when using the apparatus - 13 kilograms. One layer saves 3 kilograms. When applying three layers, this difference is already 9 kilograms, which means the price of the material will be less.

    • Treat facades and walls in a shorter time. which significantly increases labor productivity. The device applies the solution to the surface much faster. This allows you to use a wider spatula and long rule than when working manually. The wall surface becomes smoother, which is very important for further finishing of surfaces.

    The principle of operation of the unit and the technology of applying the solution

    The main element of the plastering machine is the container:

    • Water flows into it and the dry mixture is poured. The proportions of materials are programmed, which allows you to obtain a solution of only the desired consistency.
    • Here the composition is thoroughly mixed, loosened, and saturated with oxygen.
    • The mixture is applied to the surface through hoses.
    • The use of special nozzles allows you to cover a large area in a minimum time, and large rules and a spatula can level this surface in a few minutes.

    Tip: With mechanized plastering, one or two workers can complete a large amount of work, up to five times faster than by hand.

    Instructions for plastering work include:

    • Using a level, the curvature of the walls is measured.
    • At the outer corners, guide beacons made of aluminum are installed. These works are done manually.

    • The device is connected to the electrical network and a water supply.
    • The dry mixture is poured into the hopper of the plastering machine.

    Tip: If there is no water supply at the construction site, you should use the pump included in the equipment package. It supplies liquid to the hopper, regardless of the type of container.

    • The feeding auger delivers the plaster mixture to the mixing chamber.
    • The composition is thoroughly mixed with water until a homogeneous consistency is obtained.
    • Mixing occurs continuously throughout the entire operation of the machine, which allows you to obtain a solution sufficiently High Quality.
    • The mixture is supplied through a mortar hose to the surface to be treated and evenly applied to it, as shown in the photo.

    Mechanical plastering

    • The mortar on the walls is leveled using large spatulas, a trowel and a rule. In this case, the surface is rubbed until it is even and smooth.
    • The plaster mixture on the walls is left to dry.
    • Other sections of the wall are being prepared for finishing and the corners are being finished.
    • All stages of the machine plastering process are controlled by building levels.
    • The last operation is to remove small scratches and protrusions and smooth the surface with a special sponge.

    What mixture is used for devices

    Mixtures for plastering machines are produced:

    They can treat surfaces from:

    Tip: The prepared solution must be used at temperatures ranging from 5°C to 29°C. Before starting plastering, a primer corresponding to the type of surface being treated is applied.

    • A special plaster composition is used to fix the corner profile.
    • For plastering facades, the solution is made from mixtures that are intended for this type of work.
    • For interior decoration It is better to use gypsum-based mixtures. They are used to level the surfaces of ceilings and walls in rooms with low humidity. Gypsum plaster allows you to make the surface more even, smooth, with high strength and environmentally friendly.

    How to make a machine for applying plaster

    A homemade plastering machine, just like an industrial unit, allows you to apply the solution faster and with better quality than manually. One of them could be a homemade pneumatic bucket or a small hopper.

    This not very complicated device allows you to apply mortar to walls with virtually no losses, very quickly, without special preparation. How additional material To make the device yourself, there is a video in this article.

    Plastering walls with a pneumatic bucket

    Tip: This type of device is intended for finishing large areas and for plastering the entire building. If the area to be treated is small, it will take more time to install the device and, after finishing the work, to wash it afterwards.

    The advantages of the device compared to manual process, are:

    • The speed of application of the solution increases by approximately 2.5 times, without loss of coating quality - the created jet pressure promotes adhesion.
    • Finishing can be done using various admixtures and fibers.
    • The solution can be applied to walls indoors and outdoors.
    • The device is easy to clean. To facilitate maintenance, it is better to make the container from stainless or galvanized steel. The pneumatics simply need to be blown out with a working jet of air, after which all parts are dried.

    To make such a pneumatic mechanism, first of all, you should understand on what principle it works, which will facilitate the assembly of the pneumatic bucket.

    The action of the device is performed in the following sequence:

    • From the compressor, a stream of air flows through a hose into a bucket, which is filled with solution.
    • On the opposite wall of the container there are holes for pushing out the mixture under air pressure.
    • The front wall of the bucket is tilted; this will allow the mixture to be scooped out more efficiently from the container where it was prepared in advance.

    Tip: To prevent the solution from spilling when applied to the ceiling, a small lid should be made on the top of the hopper, which will cover only a third of the hole on the side from which the air will be supplied.

    • A nozzle is put on the pneumatic hose, serving as a nozzle, it inner diameter should be 5 millimeters, and the diameter of the outlet hole should be 12 millimeters.
    • The nozzle is adjusted so that the distance from it to the front wall, or to the outlet, is approximately 20 millimeters. In this case, the lower part of the bucket can be much larger: 50x50 millimeters or 70x70 millimeters.
    • The material for the manufacture of the structure is chosen from a variety of materials, from any available parts. It is important that the principle be followed: the solution is lowered through a narrow space and pushed out by air.

    For example, when the distance to the front wall from the nozzle increases to 100 millimeters, almost all the pneumatic power will be spent on the resistance of the solution, and at the top of the container only bubbles and too weak outflow of the solution through the outlet hole will be observed.

    • The sides of the bucket are fixed with two clamps attached to the edges of the hopper and the nozzle itself. In this case, the bucket receives three points of support. The clamps can be welded, secured with rivets, the front part must be fixed to a threaded connection.

    Tip: When plastering with a pneumatic ladle, you need to use a thicker solution.

    • A gun is connected to the compressor through a hose; in this case, a pressure of two to three atmospheres is required: with a higher value, the spray will inflate, with a lower value, there will be no jet.
    • When plastering, the distance to the outlet from the wall is approximately 18 centimeters, and the thickness of the layer is adjusted as necessary.

    Tip: To increase the speed of work, you should make more nozzles and outlets. In any case, the hose remains alone.

    The use of any mechanical apparatus facilitates the process of plastering surfaces.

    Do-it-yourself plastering machine: classes, sizes, solutions

    Builders never did simple work. Finishing is one of the most labor-intensive processes when performing repairs.

    But new technologies are reaching this market sector along with mechanization. Thanks to the advent of the plastering machine, the need for manually performing complex operations disappears.

    The unit replaces an entire team of finishers. From the point of view of economy, a do-it-yourself plastering machine will be profitable.

    What are these machines good for?

    Machine application of plaster

    A person must still be present nearby, because these installations do not belong to the group of autonomous robots.

    But the most routine and complex processes It is the unit itself that does this.

    If speak about physical activity, then preparing solutions is difficult. The machine can cook everything itself.

    The fact that water and dry mixtures have clearly dosed proportions becomes important, but the unit allows you to constantly obtain high-quality mixtures.

    Total exclusion guaranteed human factor, and when carrying out similar works it is important.

    The components are mixed using mechanical movements. The supply of the composition is carried out at high speed. Air is included in the solution. This saves money - the mixture takes up more volume with less spending. Compared to manual work, this decision much more profitable.

    The machine is capable of doing the same job as a whole team of workers, only much faster, and the solution is quickly and evenly applied to the walls and also takes less time to dry.

    All this contributes to the fact that it increases overall quality finishing.

    • The controls of such a machine are accessible and understandable to users of any level of training. Any buyer will understand the operating instructions, without additional help. The same goes for maintenance and repairs, if necessary.
    • The units are made with small dimensions. For transportation, the structure is equipped with handles and wheels.
    • Models are most often assembled from separate modules. The machine can be quickly disassembled and reassembled at any time. A relevant property for those who are interested in long-distance transportation and storage.
    • If the unit is serial, then all basic work processes are regulated in it. Thanks to this, the machines can be used not only on large, but also on small construction sites, with small teams of workers.

    What are the features of the technology?

    Device for uninterrupted operation need constant access to electrical network. The presence of running water is also an important requirement, but only in some situations.

    But don’t be upset if there is no device on the sites that can take water from other places. Many models are equipped with a pump that pumps liquid from any container.

    The machines have bunker parts where the mixtures are supplied in dry form. Filling of ready-made mixtures, which are produced in factories, is also acceptable.

    The solution must get inside special chambers; for this, a screw method is used. There it is mixed with water. The process is organized continuously.

    The mortar hose, its end, holds special device. It usually looks like a pistol. This allows the mixture to be applied to walls. in an even and even layer.

    The material is applied to the surface using several modes supported by plaster guns. The consistency of the solution and the type of surface being treated are determined by changes in technology.

    Functioning plastering machines on several types of pumps:

    The design necessarily includes a cyclic block. Thanks to this, mixing takes place continuously.

    Conventional plastering units have a simpler design.

    About cars made with your own hands

    How to make a plastering machine yourself

    Of course, in mass production it is easy to find high-quality and practical, powerful tools.

    But the price will be the main disadvantage for many.

    When performing a one-time job, not everyone will decide to purchase expensive equipment.

    And rent is not always available to buyers.

    But even in such situations there is a way out - homemade plastering machines.

    They will be inferior to serial models in power and performance, but have an acceptable cost.

    And working with such a tool will not cause much trouble.

    • As a basis for creating a tool such as a do-it-yourself plastering machine, we take an ordinary fire extinguisher with a capacity of up to 4 liters. It has most of the parts we need. These include pens and cylinders where solutions are placed. And a lever that opens the valve at the outlet.
    • If the volume is larger, the product will become too bulky. And a small container will need to be refilled too often.

    It all starts with cutting off the bottom of the fire extinguisher. Homemade car works the same as a spray gun. In this case, the fire extinguisher capacity plays the role of a solution hopper; its bottom should be at the top.

    And then at its end a nozzle with a diameter of 4-5 millimeters is installed. Air is supplied through it, which is taken from the compressor.

    The power of the device is determined by several factors:

    • The gap between the parts of the incoming nozzle, as well as the nozzle
    • What diameter is the outlet hole provided?
    • Air pressure

    The mixture is ejected more actively as the outlet nozzle approaches the nozzle.

    15-20 millimeters from the nozzle to the nozzle will be enough for those who perform plastering under a fur coat. But the distance to the nozzle needs to be shorter if we are talking about fine mixtures. It is important to increase the compressor pressure.

    You can complicate the design somewhat. For example, cutting threads on metal water pipes with diameters in accordance with the requirements.

    And the pipe itself is then secured to the nuts, using gaskets with a seal. Then the gap will be easier to adjust and the connection will be easier to weld.

    But the simplest option is fastening while simultaneously sealing the tube. Resin is indispensable in this process. How to create a plastering machine with your own hands - the video shows it more clearly:

    To do this you need to perform the following set of actions:

    • A certain position is important for the hopper part, which is already equipped with a tube at this stage. We need to make sure that it is 45 degrees equal to the angle between the horizon, as well as the axis of the outlet hole.
    • Pouring resin into liquid form. With that calculation, the final level was slightly lower than the nozzle. Then the fire extinguisher is left alone until the resin part has completely hardened.
    • The option when everything is filled with resin has its advantages - the liquid flows along the surface at an angle, flowing directly to the nozzle
    • It is necessary to acquire a compressor that creates pressure up to 2 atmospheres. We connect the connecting hoses and fill in the solution. You can start working.

    Application technique details

    • The surface requires careful preparation before starting work. Preparatory process- the same as before manual application of plaster. It is imperative to inspect the surface and then get rid of old finishing layers, if any. The main requirement is the absence of oil and damp stains on the materials. Only a clean, dry, strong base is allowed. Fungus and mold will only interfere with further work.
    • The next step is to move on to the primer. The process depends on what types of solution we use. For application use ordinary rollers and brushes. But you need to install corner profiles and beacons before you start work. Fastening occurs on a solution. or on mounting adhesive.
    • You can take a machine and connect it to the process. Each device comes with instructions that are as easy to understand as possible. The main thing is to carry out a preliminary check with the hoses; punctures are unacceptable.
    • Work begins when the operator stands at a certain angle in relation to the material requiring processing. The dominant hand is needed to hold the pistol. And the second one is needed to fix the hose.

    They start by transferring the mixture into cracks and depressions with large dimensions. After this, they proceed to applying the composition to the surface, distributing it evenly. It is customary to start plastering in the left corner of the room, which is located at the very top.

    If work is carried out on ceilings. That Starting point serves as an angle. Usually the one with the greatest distance.

    The composition should be applied only in the form of even strips. Each of them should have a length of 700 millimeters. The laying step is selected according to the thickness of the application.

    The plaster is laid in several layers if the material itself is thick. The main thing is that the time interval between applications does not exceed 30 minutes.

    Solutions for mechanized plastering

    It is most convenient to use mixtures that are designed specifically to do this job. Indoors, they often resort to cement bases and gypsum.

    The exception is objects where humidity is always high. For facade finishing, it is recommended to give preference exclusively to the cement component.

    Among the materials suitable for use in such situations are cement and sand mortars. But when preparing it, you need to maintain consistency and proportion.

    But it is the use of specialized mixtures that will allow you to obtain a high-quality coating. Plasticizers and other substances are added to the solutions, which improve the texture of the wall and make all the work easier. Just like creating a plastering machine with your own hands, the drawings will confirm this.

    Mixtures with special purpose provide the following benefits to owners:

    • Improvement of sound, thermal insulation properties walls If the composition contains a special component like perlite.
    • Creating a favorable climate, because the compositions are vapor permeable.
    • Easier achievement of the effect of a perfectly flat surface. This applies even to curved sections and corners.
    • High-quality connection to the walls.
    • Now drying does not take so much time.

    It is easy to find compounds on the market that are designed specifically for machine plastering. But most manufacturers prefer to supply compounds with universal functions. They are plastered both manually and mechanically.

    About plastering machines. Classes and sizes, work performed

    The most attractive are devices produced in Western countries, compared to other factory-type analogues.

    For example, the Knauf company produces devices that are distinguished by high performance characteristics, compact dimensions, and support for many functions.

    Such machines also work on the painting process, and not just on supplying the solution to the walls and its direct preparation.

    The plastering machine from RFTRitmoM is another development with miniature dimensions. At the same time, it is superior to its huge analogues, if you study the technical ones. functionality.

    Regardless of the size of the equipment, at least one or two operators are required to service these machines. Technical equipment It is almost not determined by the class and size of the devices; it is almost the same everywhere. It includes:

    • Compressor devices that spray the composition on the surface, supplying it to the materials at a certain pressure.
    • Chambers mixing the elements of the solution.
    • Containers where water and dry mixture are stored.
    • Pump supplying solution.

    Automation has become widespread in modern models. Thanks to this, the work of operators becomes easier and easier. In this case, the solution is prepared with parameters that are set precisely.

    Kits with nozzles with nozzles of different diameters also make the task easier. They determine how intense the spray flow will be.

    Additional rules for mechanical plaster

    Usually maintain a strict right angle when holding the gun next to the surfaces being treated. The gun case and the material itself must be kept at a distance. not exceeding three tens of centimeters.

    The gun moves at a certain speed, which allows access to adjust the layer that is distributed over the surface. The plaster layer will be thicker if the gun moves more slowly.

    Approximately 10 kgm2 per square meter is the consumption of MP75 plaster.

    The main thing is that the width of the grips does not exceed 70 centimeters. And each subsequent one is applied to the previous one with an overlap of 5-10 cm.

    About the types of plaster

    Plaster can be thermal insulation, cement or gypsum. Gypsum machine plaster is the most popular.

    It means that only natural materials. The environmental safety of gypsum has been scientifically confirmed.

    Cement is used if gypsum cannot be used due to the volume of work. And thermal insulation - if other materials do not allow obtaining the required characteristics.

    About the features gypsum plaster cars

    This type of work has its advantages compared to other solutions:

    • There is no need to additionally treat the walls with putty.
    • Availability of single-layer leveling of bases, with a layer of up to 50 mm.
    • The ability to regulate the indoor microclimate, environmental safety.
    • Whiteness, to a high degree.

    Qualified setup of equipment affects the result. This is the only way to avoid unnecessary waste of material. The long, expensive puttying process is easier to avoid by using modified mixtures.

    The main thing is to understand that mortar mixing pumps are needed only to work with dry mixtures. Filling the receiving hopper of machines does not tolerate free experimentation.

    Plaster mortar

    Compared to traditional compounds, specialized mixtures shrink much less.

    They resist cracks and their appearance anywhere.

    The surface is leveled in layers, with a thickness of 5 to 100 millimeters.

    Low specific weight and the ability to connect to any materials are the main advantages for practical use.

    Plastering machines have short payback periods, because they are universal. Perfect option application - when three people are involved in the work.

    One of them works with the machine, two continue to plaster and grout the walls. This will reduce the time it takes to carry out construction work. Gypsum solutions are good because very little of them is consumed.

    These materials also have a lower specific gravity compared to analogues. Thanks to this, transport costs are reduced and there is less work for the plasterers themselves. The load on the foundation is reduced to a minimum.

    The use of a mechanized method of plastering the surface allows you to obtain a perfectly flat base for further finishing in just one day. At the same time, the quality of plastering walls is much higher than when using a mechanized method. We’ll talk about how to plaster walls using a machine later.

    Machine plastering by hand: features of a machine for making plaster

    In the process of making machine plaster they use special device. Its main function is to mix the solution and ensure its high-quality mixing. As a result, it is possible to obtain a composition that is ideal in consistency for plastering.

    The manual part of the work only involves pouring the necessary components into the inside of the device. the right quantity. In the mixing part of the mechanism, the composition is mixed, and from the storage hopper the plaster is supplied to the surface. Using a special nozzle, the composition is evenly sprayed on the wall.

    This device has a rather complex structure, so it is quite difficult to make a device for machine plastering with your own hands.

    The person performing the plastering must only direct the hose away from the device, ensuring uniform coverage of the wall in relation to the beacons. Excessive application of the solution reduces the strength of the plaster, and insufficient application leads to the appearance of gaps on the walls. The optimal spray thickness is from 10 to 35 cm.

    The plastering device must include a reservoir into which water and cement flow. Thanks to a specific program, the device independently controls the proportions of ingredients. Inside a special tank, the ingredients are combined with each other.

    Special attachments significantly speed up the speed of plastering. Leveling the composition on the wall is done with large spatulas. The speed of mechanical plastering is 5 times higher than manual plastering. In addition, two people are enough to complete the work. One of them applies the composition to the wall, and the second levels it.

    You should start working by measuring the curvature of the wall. A level is used for these purposes. On external corners it is necessary to install guides made of aluminum. Next, the work is automated and involves applying the composition to the surface.

    Initially, the device is connected to water and electricity. Next, the dry composition is poured into the bunker. Some machines for making plaster are equipped with a special pump that pumps water if there is no centralized water supply in the area.

    Using a feed auger plaster composition is delivered to a special chamber in which it is combined with water. The machine performs continuous mixing throughout the entire working process. ready-made composition. Therefore, the quality of the solution has very high technological characteristics, the composition has good adhesion to the base.

    Next, the solution is transported through a hose to the surface. A spatula, a trowel, or a rule helps to level the mortar on the wall. The type of tool used is determined by the nature and location of the work. After leveling the surface, the solution is left until it dries. To control the evenness of applying plaster by machine, a level is used. In order to eliminate minor scratches, the wall is sanded using a special sponge.

    Comparing the manual and mechanized methods of plastering walls, the first has the following advantages:

    1. The solution is mixed and brought to the desired consistency using an automated method. At the same time, the physical costs of plastering are reduced.
    2. The consistency of the solution is the same at all stages of work. Because the machine constantly mixes it. Therefore, the surface is not covered with cracks or irregularities.
    3. The mechanized plastering method reduces the amount of mortar to be applied to the wall.
    4. The time required to complete the work is several times less than when using the manual method.
    5. High quality plastered surface, smooth texture, no defects.

    Mixture for mechanized plaster - preparation features

    There are two options for compositions for performing mechanized machine plastering: liquid and dry. With their help, it is possible to process surfaces of various compositions, which are based on plasterboard, concrete, reinforced concrete, brick, and aerated concrete. The temperature range for using the solution is limited to 5-30 degrees Celsius.

    Initially, you should treat the surface with a primer that improves adhesion between the wall and the plaster. After it dries, further work is carried out. The corner profile is fixed on a particularly strong plaster mortar. Facade plastering involves the use of special cement-sand based mixtures. Water is used to dilute it. Special additives in the composition of such plaster are ways to regulate the level of its plasticity and hardening time. The same compositions are used for finishing pools and premises and high level humidity.

    For internal plastering, compositions with a gypsum base are suitable. They are able to set quickly, however, they are not suitable for rooms with high humidity levels. The material allows air to pass through well, so it allows the walls to breathe. As a result, it is possible to obtain a perfectly smooth coating for further finishing.

    When working with cement-sand compositions, you must wait until they dry completely so that they gain strength. The composition that is applied by machine is more liquid than that applied by hand. Since it should be splashed over the surface.

    Plastering walls using a mechanized method - technology

    The relevance of using a mechanized method of applying plaster is primarily justified indoors large area. The process of plastering them lasts one or two days, while doing it manually would not be enough even a week.

    To perform mechanized application of plaster, you must have a plaster station and a gun, which has a compressor that supplies the composition under pressure. In the end we manage to get the perfect smooth walls, the plaster on which is durable and has a long service life.

    The plastering station is independent system, inside which the solution is prepared. Then it gets to the gun and is fed onto the wall. The dry composition is poured into a bunker container, which is filled with water. It is necessary to hold the gun firmly, as the solution is supplied under high pressure. The gun should be at right angles to the surface that will be plastered.

    Another option for performing mechanized machine plastering is to use a cartouche gun. This device does not prepare the solution on its own, but involves pouring it already ready mixture V top part device. Next, the compressor is turned on, which sprays the solution over the surface. The gun is constantly held in the hands and creates a high mechanical load on the person working with it. It is less convenient than a plastering station.

    Another option for applying plaster using a mechanized method is the use of a pneumatic shovel. Throwing the composition onto the wall is carried out using a special steel container that scoops up the composition.

    There are shovels for walls or for ceilings; in addition, they differ in relation to the shape, size and location of the buckets. The productivity of working with such a device is an order of magnitude lower than with a special station.

    In any case, before applying mechanized plaster, it is necessary to prepare the surface. The walls or ceiling are cleaned of dust and dirt, and beacons are installed. Next, the primer composition is applied, and then the corner guides are installed. Since they are made of metal, they must be treated with an anti-corrosion compound.

    After this, plastering of the surface begins. Dry mixtures are placed in the hopper of the machine; most models of devices for performing mechanized plastering determine the amount of water independently by using pumping station. The plaster is applied in a direction perpendicular to the walls. If there is excess, it is directed to a part of the wall that has not yet been filled with plaster or to hard-to-reach places.

    Grouting of the plaster is carried out after 3-4 hours from the moment it is applied to the wall. With its help, it is possible to get rid of significant defects on the walls and make them smooth. Next, you need to wait until the composition dries completely, which takes three days. After this, they begin to finish plastering the surface. If there is high humidity in the room, the drying time of the composition increases to seven days.

    The hose from the machine must be led along a line, the next line must half overlap the previous one. Thus, it is possible to achieve a uniform distribution of the composition on the wall and increases the smoothness of the coating. The lighthouses should be under the plaster.

    If beacons made of metal were used, they are removed immediately after the work is completed. Thus, the walls will not be covered with corrosion. To plaster the grooves under the beacons, use hand tools.

    The final stage is grinding the surface using a rubber float. The surface is moistened with water and rubbed down. Thus, using a device for machine plastering greatly simplifies the process of preparing the solution and applying it to the surface.

    Technology of applying plaster using a mechanized method

    The process of applying plaster to walls using a mechanized method consists of the following stages:

    1. Transportation of equipment to the construction site. Installation and configuration of the station.
    2. Working on work areas: removal old decoration, grouting and priming walls.
    3. Checking walls for evenness using a level. Marking areas for applying plaster.
    4. Leveling the mortar on the wall, if necessary, re-applying and leveling the plaster.
    5. Finishing using the rules. Performing puttying of walls.

    During the process of performing mechanized screeding of plaster indoors, the air temperature for the work must be at least +12 degrees. At the same time, the humidity level should not exceed 60%.

    In addition, the room must have glazed window openings, a heating system, and a leveled screed. Internal and external plastered surfaces must be protected from exposure to excessive moisture.

    Mechanized facade plastering

    The process of mechanized plastering of facades is quite complex, and it is almost impossible to cope with it without experience. Therefore, if you have not previously plastered walls using a mechanized method, then it is better to entrust this issue to professionals.

    The initial stage of work involves a visual inspection of the work site. Determining the curvature of walls, taking measurements on walls and setting angles. Next, the amount of material used in the work is determined and purchased.

    Any repair is not complete without auxiliary tools and a large number of 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. for internal and external ones are of great importance: they are the most painstaking and time-consuming, and the result in the literal sense should 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: can be applied dry or 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 a future factory or high-rise office or apartment building is quite difficult. This will be long and difficult even with the most experienced team of plasterers.

    In addition, you can use equipment that works on 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

    1. 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.
    2. 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.
    3. Installation of profiles for processing corners.
    4. Applying primer.
    5. The plastering machine is equipped with a special tank in which the mixture is prepared for subsequent application to the dried primer.
    6. Applying the mixture with a technical gun, which distributes it evenly over the wall.
    7. 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.

    Equipment selection

    Plastering machine, reviews of which are predominantly positive due to its great benefits, must serve for a long time and meet all customer requirements. Manufacturers today offer a wide selection different models, which are capable of plastering surfaces. The most popular are German, Austrian and Polish models of this technology. Manufacturers are ready to offer entire specialized stations or fairly simple units that can operate in various weather conditions, with a large temperature difference from 30 degrees hot to minus 40 in winter.

    The angle grinder-150 model is in great demand among construction organizations. Plastering machine of this modification according to technical and quality characteristics meets all the requirements for high-quality plastering, painting and preparation various types mixtures. In addition, for greater convenience, it is equipped with a control and adjustment center. This allows you to control the speed and force of the solution supply.

    What criteria should you use to make a choice?

    The main criteria for purchasing should be:

    1. Easy to use. It is important that a person can handle the controls even without special construction skills.
    2. Saving materials. As a rule, the solution consumption for machine plastering is much less than for manual plastering.
    3. Low power consumption.
    4. Suitable dimensions and light weight. Dimensions should be chosen taking into account how many people will work with the equipment and how extensive the finishing work is.
    5. Functionality. Often these machines are equipped with equipment for painting walls.
    6. Reliability and quality of the device.
    7. Easy to transport and assemble at different sites.

    If all these conditions are met, you can safely purchase such an assistant and perform a wide range of tasks. repair and finishing works not only walls, but also flooring.

    Alternative

    Of course, not everyone can afford to purchase such a unit. Its price varies from 2 to 20 thousand euros. It is most often used by specialized companies that have repair and construction teams. This has a positive effect on the image of the organization and attracts customers. In addition to purchasing, you can also consider renting a car. It will be somewhat cheaper. And even, to some extent, simpler.

    As a rule, in private we do not do repairs too often, especially such extensive ones, with complete renovation of walls and floors. Buying an expensive tool will be impractical. It may not always be possible to resell it. Therefore, taking it one-time for the period of specific finishing work will be quite acceptable.

    Do it yourself

    In addition to buying and renting, a fairly good option for acquiring equipment is to assemble a device such as a plastering machine with your own hands. Of course, it will not have a completely standard appearance, but it can perform the same functions, and you can even add something new.

    Perhaps its performance and power will not be as high. Skillful craftsmen They can use broken household items for this purpose. The simplest and most common configuration homemade equipment something like this:

    • Old fire extinguisher.
    • Nozzle.
    • A tube.
    • Compressor.

    It turns out to be quite convenient and, as they say, low-budget option. Such a manual plastering machine will make your work easier and help you deal with difficult places on the surface, even if you are not professional craftsman for finishing works.

    The main function of an automatic device for plastering surfaces is to perform high-quality mixing of the solution and further ensure its high-quality and fast mixing. Such machines make it possible to obtain a composition that is ideal in consistency and intended for plastering walls.

    Advantages of plastering machines over manual labor

    The advantage of plastering machines in this case is very noticeable. The most important advantage of using the device is independence and freedom from routine manual labor in preparing the solution. The machine will greatly facilitate and speed up the work process for one person. Additional advantages of plastering machines are the following operating points.

    • As a rule, preparing a solution for plaster requires a person to maintain exact proportions between water and dry mixtures when mixing. While people may make mistakes in their calculations, specialized plastering machines are designed to maintain precise dosages and prepare high-quality mixtures automatically.
    • Dry mixtures are mixed mechanically using such devices. This is a tangible advantage, because it will be difficult and time-consuming for a person to mix large volumes of solutions. Plaster machines, on the contrary, mix quickly and efficiently, and the accelerated feed allows you to contain a large amount of air in the finished solution, which, in turn, allows you to save the dry mixture, because at the same cost the solution is produced by an order of magnitude more.
    • One plastering device is a modern alternative to almost a whole construction team, specializing in plastering works. The machine applies even, thin layers that dry faster, resulting in higher quality layers and significantly speeding up the work process.

    Should I buy or not?

    You can buy a plastering machine in a store, or you can make it at home. Prices for factory-made plastering machines leave much to be desired (especially given that these machines can be made with your own hands). Therefore, such purchases will be unprofitable and completely impractical. It is important to understand that with the right approach, homemade machines are not handicraft production, but significant savings Money with the same final results.

    The operating principle of a homemade plastering machine

    To understand the working mechanism homemade device, you need to imagine the principle of operation of an ordinary spray gun (or at least a spray gun). It is based on a conventional fire extinguisher. The fire extinguisher container will act as a solution hopper, so its bottom should be on top.

    The fire extinguisher cylinder should have a volume of about 4 liters. It is fire extinguishers, as blanks, that are equipped with everything necessary to create a machine for spraying plaster mixtures: they have a nozzle, a handle and a lever that opens holes at the outlet.

    Manual labor when using this unit only means pouring the necessary mixture inside the device. The composition is mixed in the mixing compartment of the apparatus, and the finished plaster solution is supplied outward from the storage hopper. Using a nozzle, the solution is evenly sprayed onto the wall (as is the case with a spray gun).

    How to make a plastering machine with your own hands?

    So, the sequence of actions for self-production devices for plastering surfaces are as follows.

    1. First of all, you need to cut off the bottom of the fire extinguisher. In the future, the homemade unit will be positioned with the nozzle down (bottom up). A container with a cut bottom is a kind of hopper for the solution.
    2. A homemade sprayer is complemented by a tube through which compressed air will be supplied. It cuts into the side wall of the cylinder, located opposite the valve outlet. The mixture will be sprayed through this outlet. Compressed air is transmitted through a pipe from the compressor, and for high-quality spraying of the solution, the nozzle must have a diameter of no more than 4-5 mm.
    3. The power of a homemade machine directly depends on the diameter of the nozzle, the pressure of the supplied compressed air, and a certain gap between the compressor nozzle and the nozzle. Therefore, to increase power, the air supply tube should be placed as close as possible to the outlet valve and properly secured. It is secured with nuts and gaskets. This makes it easier to adjust the distance from the tube to the valve. The connection should be welded.
    4. The final stage is installation air compressor. It should be connected to the nozzle hole using a hose. For the homemade unit to operate, it is necessary to create a pressure of 2 atmospheres. If there is little pressure, the finish will be rough. If you want a smooth finish that fills all the pores on the wall, you need to apply high pressure.

    The golden rule of plastering work

    1. Before applying a new plaster layer, the surface must be thoroughly cleaned of old plaster.
    2. Another requirement is the absence of wet and oil stains on the walls. Only a dry, clean and strong base is allowed.
    3. Mold and mildew will also interfere with further work.
    4. A person working with a homemade plastering machine must direct the unit’s hose to the wall, ensuring uniform coverage in relation to the beacons. If the solution is applied in excess, the strength of the plaster will noticeably decrease. If the solution is applied insufficiently, characteristic gaps will appear on the walls. Optimal thickness plaster is a layer of 12 to 30 cm.

    Final word

    So, working with plastering units is a significant saving of time and material consumption (dry building mixtures). This creates a durable and high-quality coating that does not require further puttying or finishing to level the surfaces. In addition, such devices are easy to operate: working with them is possible even for an untrained person who has done cosmetic repairs in his home at least once in his life.

    The use of a mechanized method of plastering the surface allows you to obtain a perfectly flat base for further finishing in just one day. At the same time, the quality of plastering walls is much higher than when using a mechanized method. We’ll talk about how to plaster walls using a machine later.

    Machine plastering by hand: features of a machine for making plaster

    In the process of making machine plaster, a special device is used. Its main function is to mix the solution and ensure its high-quality mixing. As a result, it is possible to obtain a composition that is ideal in consistency for plastering.

    The manual part of the work only involves pouring the necessary components into the inside of the device in the required quantities. In the mixing part of the mechanism, the composition is mixed, and from the storage hopper the plaster is supplied to the surface. Using a special nozzle, the composition is evenly sprayed on the wall.

    This device has a rather complex structure, so it is quite difficult to make a device for machine plastering with your own hands.

    The person performing the plastering must only direct the hose away from the device, ensuring uniform coverage of the wall in relation to the beacons. Excessive application of the solution reduces the strength of the plaster, and insufficient application leads to the appearance of gaps on the walls. The optimal spray thickness is from 10 to 35 cm.

    The plastering device must include a reservoir into which water and cement flow. Thanks to a specific program, the device independently controls the proportions of ingredients. Inside a special tank, the ingredients are combined with each other.

    Special attachments significantly speed up the speed of plastering. Leveling the composition on the wall is done with large spatulas. The speed of mechanical plastering is 5 times higher than manual plastering. In addition, two people are enough to complete the work. One of them applies the composition to the wall, and the second levels it.

    You should start working by measuring the curvature of the wall. A level is used for these purposes. Guides made of aluminum must be installed on the outer corners. Next, the work is automated and involves applying the composition to the surface.

    Initially, the device is connected to water and electricity. Next, the dry composition is poured into the bunker. Some machines for making plaster are equipped with a special pump that pumps water if there is no centralized water supply in the area.

    Using a feed auger, the plaster composition is delivered to a special chamber in which it is combined with water. The machine continuously mixes the finished composition throughout the entire working process. Therefore, the quality of the solution has very high technological characteristics, the composition has good adhesion to the base.

    Next, the solution is transported through a hose to the surface. A spatula, a trowel, or a rule helps to level the mortar on the wall. The type of tool used is determined by the nature and location of the work. After leveling the surface, the solution is left until it dries. To control the evenness of applying plaster by machine, a level is used. In order to eliminate minor scratches, the wall is sanded using a special sponge.

    Comparing the manual and mechanized methods of plastering walls, the first has the following advantages:

    1. The solution is mixed and brought to the desired consistency using an automated method. At the same time, the physical costs of plastering are reduced.
    2. The consistency of the solution is the same at all stages of work. Because the machine constantly mixes it. Therefore, the surface is not covered with cracks or irregularities.
    3. The mechanized plastering method reduces the amount of mortar to be applied to the wall.
    4. The time required to complete the work is several times less than when using the manual method.
    5. High quality plastered surface, smooth texture, no defects.

    Mixture for mechanized plaster - preparation features

    There are two options for compositions for performing mechanized machine plastering: liquid and dry. With their help, it is possible to process surfaces of various compositions, which are based on plasterboard, concrete, reinforced concrete, brick, and aerated concrete. The temperature range for using the solution is limited to 5-30 degrees Celsius.

    Initially, you should treat the surface with a primer that improves adhesion between the wall and the plaster. After it dries, further work is carried out. The corner profile is fixed on a particularly strong plaster mortar. Facade plastering involves the use of special cement-sand based mixtures. Water is used to dilute it. Special additives in the composition of such plaster are ways to regulate the level of its plasticity and hardening time. The same compositions are used for finishing swimming pools and rooms with high levels of humidity.

    For internal plastering, compositions with a gypsum base are suitable. They are able to set quickly, however, they are not suitable for rooms with high humidity levels. The material allows air to pass through well, so it allows the walls to breathe. As a result, it is possible to obtain a perfectly smooth coating for further finishing.

    When working with cement-sand compositions, you must wait until they dry completely so that they gain strength. The composition that is applied by machine is more liquid than that applied by hand. Since it should be splashed over the surface.

    Plastering walls using a mechanized method - technology

    The relevance of using a mechanized method of applying plaster is primarily justified in large areas. The process of plastering them lasts one or two days, while doing it manually would not be enough even a week.

    To perform mechanized application of plaster, you must have a plaster station and a gun, which has a compressor that supplies the composition under pressure. As a result, it is possible to obtain perfectly smooth walls, the plaster on which is durable and has a long service life.

    A plastering station is an independent system within which the solution is prepared. Then it gets to the gun and is fed onto the wall. The dry composition is poured into a bunker container, which is filled with water. It is necessary to hold the gun firmly, as the solution is supplied under high pressure. The gun should be at right angles to the surface that will be plastered.

    Another option for performing mechanized machine plastering is to use a cartouche gun. This device does not prepare the solution on its own, but involves pouring the ready-made mixture into the upper part of the device. Next, the compressor is turned on, which sprays the solution over the surface. The gun is constantly held in the hands and creates a high mechanical load on the person working with it. It is less convenient than a plastering station.

    Another option for applying plaster using a mechanized method is the use of a pneumatic shovel. Throwing the composition onto the wall is carried out using a special steel container that scoops up the composition.

    There are shovels for walls or for ceilings; in addition, they differ in relation to the shape, size and location of the buckets. The productivity of working with such a device is an order of magnitude lower than with a special station.

    In any case, before applying mechanized plaster, it is necessary to prepare the surface. The walls or ceiling are cleaned of dust and dirt, and beacons are installed. Next, the primer composition is applied, and then the corner guides are installed. Since they are made of metal, they must be treated with an anti-corrosion compound.

    After this, plastering of the surface begins. Dry mixtures are placed in the hopper of the machine; most models of devices for performing mechanized plastering determine the amount of water independently, using a pumping station. The plaster is applied in a direction perpendicular to the walls. If there is excess, it is directed to a part of the wall that has not yet been filled with plaster or to hard-to-reach places.

    Grouting of the plaster is carried out after 3-4 hours from the moment it is applied to the wall. With its help, it is possible to get rid of significant defects on the walls and make them smooth. Next, you need to wait until the composition dries completely, which takes three days. After this, they begin to finish plastering the surface. If there is high humidity in the room, the drying time of the composition increases to seven days.

    The hose from the machine must be led along a line, the next line must half overlap the previous one. Thus, it is possible to achieve a uniform distribution of the composition on the wall and increases the smoothness of the coating. The lighthouses should be under the plaster.

    If beacons made of metal were used, they are removed immediately after the work is completed. Thus, the walls will not be covered with corrosion. To plaster the grooves under the beacons, use hand tools.

    The final stage is grinding the surface using a rubber float. The surface is moistened with water and rubbed down. Thus, using a device for machine plastering greatly simplifies the process of preparing the solution and applying it to the surface.

    Technology of applying plaster using a mechanized method

    The process of applying plaster to walls using a mechanized method consists of the following stages:

    1. Transportation of equipment to the construction site. Installation and configuration of the station.
    2. Work on work areas: removing old finishes, grouting and priming walls.
    3. Checking walls for evenness using a level. Marking areas for applying plaster.
    4. Leveling the mortar on the wall, if necessary, re-applying and leveling the plaster.
    5. Finishing using the rules. Performing puttying of walls.

    During the process of performing mechanized screeding of plaster indoors, the air temperature for the work must be at least +12 degrees. At the same time, the humidity level should not exceed 60%.

    In addition, the room must have glazed window openings, a heating system, and a leveled screed. Internal and external plastered surfaces must be protected from exposure to excessive moisture.

    Mechanized facade plastering

    The process of mechanized plastering of facades is quite complex, and it is almost impossible to cope with it without experience. Therefore, if you have not previously plastered walls using a mechanized method, then it is better to entrust this issue to professionals.

    The initial stage of work involves a visual inspection of the work site. Determining the curvature of walls, taking measurements on walls and setting angles. Next, the amount of material used in the work is determined and purchased.

    On next stage Scaffolding is installed, cracks are cleaned and opened, if any. The surface is cleaned of dirt and dust, the facade is washed and dried. To protect the facade from moisture, mildew and mold, as well as to ensure tight adhesion of the plaster to the wall, a primer is applied to the surface in two layers. Next, if necessary, a reinforcing mesh is mounted and beacons with corners are installed.

    The corners also need to be installed on the windows. Plastering is done from bottom to top. Followed by leveling the newly applied solution. After the solution has set, it is necessary to get rid of the beacons.
