Wall machine plaster – the necessary tools, mixtures and application technique

Welcome to our wall machine plastering guide! Machine plastering is a practical and efficient method if you want your walls to be perfectly smooth and flawless. This approach is well-liked by both professionals and do-it-yourselfers because it guarantees a consistent application while also saving time.

A few necessary supplies and tools are required for wall machine plastering to be completed successfully. The most important thing you’ll need is a trustworthy plastering machine. Selecting a machine that fits the size of your project is essential because these machines come in a range of capacities and sizes. A mixing paddle attachment for the machine is also necessary to guarantee a well-prepared and uniform plaster mixture.

Another important element is the plaster mixture itself. Usually, it is composed of plaster made of gypsum or cement, which must be properly diluted with water. To guarantee an even application, this mixture needs to be lump-free and smooth. Pre-mixed plasters can be more convenient and guarantee consistency, which is why some pros prefer them.

The technique is simple to apply but takes some practice to become proficient in. First, fill the hopper of the machine with the plaster mixture. Next, evenly apply the plaster to the wall surface using the machine. To ensure an even coat and prevent gaps, move the machine consistently, slightly overlapping each pass.

It’s critical to monitor the plaster layer’s thickness as you work. To get the appropriate thickness and finish, adjust the machine’s settings. After applying, you will need to use a trowel to smooth the surface in order to get rid of any lines or imperfections the machine left behind.

Make sure you give the plaster enough time to dry completely after finishing the plastering process. Depending on the type of plaster used and the surrounding circumstances, this drying time may change. After the surface has dried, you can give it more finishing touches to add more protection and style, like sanding or applying a topcoat.

Achieving professional-looking walls can be accomplished with machine plastering if the proper equipment, supplies, and methods are used. Learning this technique can help you save time and effort while producing excellent results, whether you’re working on a larger project or remodeling your home.

Plaster in the mechanized way – what is it

When we talk about mechanized plastering, we’re talking about surface decoration where the wall plaster is done on a machine. Specialized equipment is used to implement this method, allowing for the partial or complete abandonment of manual labor. The end result is an order of magnitude higher quality of cladding and several times faster progress through all stages.

The process of making machine plaster is quite intricate. Equipment availability, information ownership, and specific job skills are necessary for its implementation. A poor tool selection and a lack of professionalism will probably lead to a poor outcome. You must receive instruction and practice in order to perform independent manipulations.

Features and specifics of the method

There are various automated plaster application technologies, and they vary in these ways:

  • degree of mechanization;
  • principle of operation;
  • method of kneading plaster;
  • Monitoring the amount of water.

The master himself applies pressure to the working surface during the manual application of building mixtures, ensuring that the solution adheres to the base properly. Because the composition is already under pressure from the plastering machine technique, it is consistently clamped with the base. Every stage of the work process is substantially streamlined as a result of the machine replacing manual labor.

Any vertical and horizontal surface, including internal walls, ceilings, and facades, can be aligned with mechanical plaster. Building mixtures with modified consistency and composition are used for its implementation. Plaster will not adhere to the surface properly without careful attention to component proportions, mixing, and preparation; additionally, costly equipment may become ruined.

Types of jobs

There are essentially no geographical limitations on the application of machine plaster. Regarding the seasonality of work, there are only suggestions. Therefore, since facades and other external surfaces should be at least +20 degrees, it is not worthwhile to place them in the winter. If not, the completed layer is breaking off quite quickly.

Internal work

All kinds of solutions can be used to decorate walls in homes, apartments, and other heated spaces, but gypsum is the best option because it’s easier to apply and requires a thinner layer. All that needs to be kept in mind is that equipment cleaned with gypsum mixtures needs to be done quickly, as gypsum becomes difficult to remove after it hardens.

When working outside, it’s critical to prepare the surface qualitatively by applying soil and removing any significant defects. The walls are first wetted with water just prior to plastering, and only then is the composition sprayed. The mounting net is in advance for the dependable holding of an impressive layer of cement plasters. Monolithic walls, which are excessively smooth and do not provide the required adhesion power to the solution, are another application for reinforcing material.

Faced facade cover

Working with exterior surfaces is done during the warm season, but not in direct sunlight or during windy conditions. It is only at plus temperatures that a high-quality solution can be worked into the walls to achieve the proper leveling. For facade finishes, cement-sand mixtures with a sizable fraction are typically utilized, and the equipment setup parameters should be matched with the particle size. When applying a layer of decorative plaster with pebbles or other inclusions, you must carefully configure the machine.

Dry mixture

Both pre-made solutions and dry construction mixtures can be used for mechanized plastering; in the latter instance, manual labor will be further reduced. It’s critical that the apparatus has access to running water and is wired into a typical power grid. This is how the work order will look:

  • the drying of the dry mixture into a special container;
  • connecting the machine to the network;
  • setting up the parameters of mixing the solution;
  • preparation of plaster with a homogeneous consistency;
  • The supply of solution to the working surface under pressure.

Plaster’s perfectly level, air-structured surface ensures that the surface quality will be very high. Such walls can be used, even without puttying, for staining or pasting thin wallpaper after they have dried.

Surfacing surfaces with ready -made solutions

You won’t need to worry about the water supply if the plaster is poured into the device in its completed form. The mixture is continuously mixed by a machine, which lengthens the setting process and increases the time it takes to harden. The best options for filling the screed on the floor and plastering the ceiling are prefabricated construction solutions. To ensure that the plastering turns out perfectly, it is only necessary to level the beacons and prepare the base beforehand.

Equipment and tools

Plaster application can be made more mechanized by using the wide range of tools and technology available in the specialized departments. You can identify the most basic plaster buckets, handguns, automated stations, and even robot-stomachs among them.


A pneumolopath is a metal bucket with holes for plaster below that has a capacity of at least three to five liters. Conversely, the quantity of air nozzles is comparable to the number of holes for the plaster composition supply. The kit features a sliding handle that lets you adjust the working pressure (typically between 4 and 6 atmospheres) and the solution supply. You will need to purchase a hose and a compressor with a 35 cubic meter per hour capacity separately for such a device.

Pneumolopaths are available in two varieties: ceiling and wall, which vary in the bucket’s shape and handle location. Working with any of the devices is not that different from using plaster stations. The solution is put in at a slight angle to the wall, kneaded beforehand, and then collected with a hopper. The plaster is then sprayed onto the base by providing compressed air after the machine has been turned on.


A plaster container is attached to the handle of a pistol that has a barrel-record on it. The container is fairly large (up to 9–10 l) and can be made of plastic or metal. After various nozzles are fastened to the barrel, a starting hook is created by applying pressure, and the plaster is subsequently applied to the wall. The construction mixture supply ends after several presses. Using a pneumatic pistol, you can perform the following tasks:

  • black trim;
  • finish applying the solution;
  • textured spray.

These devices are the least expensive when it comes to labor plaster mechanization. Although using them is not difficult, it is preferable to begin practicing on smaller surfaces.

Plastering machines and stations

Plastering machines are an ideal solution for areas between 30 and 50 kV. m that require significant volumes of work. Usually owned by professional construction teams, these devices are as expensive as rent. The design of plastering installations is intricate. These are their principal hubs:

  • Bunker for dry plaster mixture;
  • a capacity for kneading and storage of finished plaster;
  • Speech supply system;
  • Control block;
  • compressor.

Plastering stations of the school type are fully automated. The plaster is kneaded, then forced into the sprayer and applied to the surface to be treated. The completed construction mixture, which is kneaded by the master in other equipment or by hand, must be filled into pneumatic machines.

The plastering stations that are imported are usually more functional than those that are domestic, and they usually have larger sizes. However, foreign machines are more "selective" while the majority of these devices can operate with any kind of solution. Certain plastering stations can also be used for bulk flooring, paint, and lime spraying.

One operator can handle devices with small to average dimensions and complexity, but many specialists are needed to handle high-tech devices. You must give the hoses, containers, and special cleaning modes a thorough rinse right away after the plastering process is finished.

Robot stuckers

Plastering stations of this kind let you apply a solution to even vertical bases. The device’s center is moved along guides that are fastened to the ceiling and floor.

The construction mixture can be prepared using a mixer and conventional plasters; it is kneaded separately, even before serving in the device. Robot stickers are typically used to decorate structures no taller than seven meters. Additionally, it is not appropriate for use on uneven bases, ceilings, staircases, or facades.

Plastering devices

Plastering can be done by hand and alignment of the previously prepared walls is possible with the disk stucco-and-out settings. A flexible shaft with an electric drive—a rotary engine with a low voltage (42 V) and an average current frequency (200 Hz)—is linked to a foam nozzle or chipboard. Even when using wet bases, the operator is not at risk of an electric storage. The nozzle of single-disc grouting machines rotates in a single direction. In two-disc devices, there are two circles that have the ability to rotate in opposite directions.

Solutions for plastering work

Two different types of mixtures based on cement and gypsum are used for mechanized plastering.

Cement-sand compositions

Sand and cement-infused plaster is thought to be the most common, particularly for wet rooms and facade work. It is extremely durable, adapts well to temperature changes, and doesn’t need to be repaired frequently. With bases of various kinds, cement plasters boast of excellent adhesion, and there are enough standard procedures to get ready for work. One benefit worth mentioning is the low cost of cement-sand plasters, as they are inexpensive in all respects.

The following are some drawbacks of such solutions:

  • unsuitability for plastic, wood, paints;
  • significant weight of the plaster layer;
  • the need for finishing (putty);
  • Long drying time.

Gypsum compositions

Plasters based on gypsum are safe, gentle on the environment, and lightweight, meaning the finished layer won’t drag on the wall too much. They work on almost any surface and don’t usually require reinforcement. Among the additional benefits of gypsum plasters are the following:

  • lack of shrinkage, deformation, cracking after drying;
  • increased heat, sound insulation of the building;
  • maintaining the optimal microclimate in the premises;
  • non -combustibility, fire safety;
  • excellent aesthetic qualities, ideal whiteness and evenness.

Gypsum solutions are orders of magnitude more expensive than plasters made of cement and sand. Nonetheless, the overall costs of repair will be roughly the same because of the minimal consumption. Because of their high porosity, gypsum plasters should not be used in damp rooms or for exterior work as they can become impregnated with water and crumble.

We go through all of the necessary equipment, materials, and application methods in our guide to wall machine plaster. For a smooth finish, selecting the appropriate tools is essential, such as a plastering machine that fits the job. To ensure workability, mixtures need to be properly prepared, with the right amount of plaster to water. Apply the plaster starting at the top and spreading it evenly with even strokes. This minimizes the need for later corrections and guarantees a consistent finish.

Choosing plaster

You must first choose the kind of construction mixture to use. While some attitudes require using pre-made compositions, others can knead the solution themselves. The type of surface is taken into consideration when choosing the composition: some plasters are thought to be universal, while others are better suited for a particular material, such as concrete, brick, cellular concrete, foam blocks, etc., because specific modifiers are available for them. D.

When purchasing, you should consider the degree of plasticity, strength, and drying speed of the solution (which can also be controlled by adding different substances). For street work, stucco needs to be resistant to frost and able to endure numerous freezing and thawing cycles. It makes sense to choose gypsum plaster for work rather than wet plaster if finishing putty is not going to be applied.

Preparation of surfaces

It’s crucial to thoroughly prepare all work surfaces before beginning mechanized plastering:

  • the old finish, which is poorly attached on the wall, remove, clean the paint and influx of plaster, rinse the lime;
  • clean the walls of dirt, dust, which is especially important for street grounds;
  • The hollows, the collapsing areas to clean the maximum, reinforce with a fiberglass mesh, and close up with cement plaster;
  • Treat metal elements with an anti -corrosion composition;
  • Cross the cracks and also close up with plaster;
  • exhaust the base by processing deep penetration into 1-3 layer (depending on the degree of porosity);
  • If necessary, distribute special plastering profiles in the corners.

It happens that moisture is strongly absorbed by the exterior surfaces. In this instance, priming the "concrete contact" and wetting the wall beforehand, applying a thin layer of solution, letting it dry, and then continuing with standard plastering will all be beneficial.

Equipment adjustment

The plastering devices’ readiness for use is assessed prior to work. Adjustment and modification are typically done right where the facades or premises are decorated. Verify the machine’s adherence to safety rules, establish a test connection to the mains, and locate a water supply source (barrel, stationary network, etc. D.).

Either determine the final solution’s density or precisely measure the required amounts of water and dry mixture. In the event that the manufacturer’s instructions specify that it is necessary, additionally configure the required parameters.

Stages of plastering

Using lighthouses will make plastering easier and enable you to level the walls more quickly and accurately. Measure the base carefully to determine the most convex section, which will serve as the upper point for applying the solution, before installing the guides. They begin plastering and grouting the walls after mending the beacons. If the work is being done inside, make sure that drafts don’t appear at all.

Application of plaster

First, the plastering installation is wired into the network, and either plaster powder or the completed composition is poured into it. Joints of the structures start after the corners and fill the main space last. Depending on the type of device, the nozzle should be held 15 to 30 cm away to ensure that the plaster spray is perfectly perpendicular. Each fresh solution strip ought to slightly overlap the preceding one, but not to the extent that lighthouses have observed. The plaster layer is produced thinner the faster the nozzle operates.

Surface alignment

Plaster is applied in accordance with the rule, unless, naturally, a robot-stomach is utilized for the task. Large spatulas and ironers are also used for this purpose. The beacons are either taken out or, depending on the technology chosen, left inside. They "increase" the plaster manually and level it again if it turns out that the layer is too thin in some places. It is crucial to complete this phase of the process as soon as the plaster is applied, while it still has some fluidity.

Cutting the solution

Twenty minutes following alignment, use a cutter (trapezoidal rule) to create the solution, which will aid in the formation of a finish in the end. Initially, they apply the tool to the surface and drag it slightly, mimicking the act of severing the outermost layer. Aim to prevent the main layer from trailing behind him. If not, they wait a little longer before manipulating again. It is acceptable to leave up to 2 mm of vibrations for every 2 linear meters on a flat plane.

Surface alignment

They start grinding the base after 20 to 30 minutes (you can start this stage after 2-3 hours, but only after first giving the wall a thorough water spray). Grators, ironing boards, and grouting machines are used for this purpose. If the surface is ready to be painted, glossy is applied six hours after wiping and is achieved by repeatedly ironing with a wet tool.

Advantages and disadvantages of the mechanized method

Plaster application with specialized equipment has advantages and disadvantages. These are its principal benefits:

  1. High speed. Purrender of any surfaces occurs an order of magnitude faster than with manual application of the construction mixture. Depending on the type of plaster, acceleration occurs 4-7 times, moreover, there is no hard physical work.
  2. Enhanced adhesion. The release of a solution under pressure, which is the same during the entire work process, helps to improve the quality of adhesion to the base. To achieve a similar effect with manual application, you need a lot of time and physical effort.
  3. Great quality. Mixing the solution in plastering installations is carried out in continuous mode. This helps to make the mixture a homogeneous, with a smooth texture, so the dried layer dries evenly, does not crack, does not bond. The finished plaster is monolithic, without seams and ugly joints.
  4. Significant area. Using a mechanized method, you can immediately process the whole room without breaks, which also reduces the risk of cracks and accelerates the repair time in general.
  5. Saving material. Some equipment allows you to reduce the consumption of the plaster mixtime compared to manual application. This is achieved by optimizing the viscosity of the solution and preventing its damage, leaving for work, beaten off the wall.
  6. Universality of equipment. Many types of plastering stations make it possible not only to apply plaster, but also to fill in cement-sand screeds on the floor.

Mechanized plastering has drawbacks as well. Because work-related equipment can be costly, it is inappropriate to independently purchase high-tech stations and robots. However, basic equipment like a hopper-chopped is considerably less expensive, and any master can purchase one. When installing a machine, two people are usually required, so you must invite an assistant.

Energy-dependent electrical installations require the connection of a diesel generator at remote locations and in newly constructed homes without electricity. Additionally, you must acquire experience in the upkeep, cleaning, and operation of complicated equipment before using it. If there are neighbors nearby, applying the plaster in the evening or at night won’t work because plaster devices typically make a lot of noise.

Which plastering is better – manual or mechanized

Every technique has pros and cons of its own, so selecting a specific approach should be done on an individual basis based on needs and resources. In order to make an informed choice, familiarize yourself with the following conclusions:

  1. For the price, some stucco for stations and pneumolopaths are cheaper than similar compositions for manual application. But in this case we are talking about gypsum solutions that contain additional improvers and modifiers. If you prepare the composition for applying the spatula yourself, mixing cement, sand, water, then the costs will be much lower than when buying a dry mixture in packages.
  2. With mechanized wall decoration, for each square meter of area, the area is spent 2-3 kg less than the solution than with manual plastering. This advantage is lost only due to the replacement of a more expensive mixture with a cement made with your own hands.
  3. With strict observance of technology and sufficient professionalism, it is possible to achieve no less high quality manual decoration than with mechanized plastering. So that the finished layer does not crack, you can use fiber fiber fiber, and the problem will be solved.

Which method is cheaper

The price of automated stucco installation starts at 220 rubles per square meter and goes up from there. The cost of manual plaster is typically higher, ranging from 250–300 rubles for a square meter of the first layer to 550 rubles for three layers. However, in actuality, the cost of wall decoration with specialized equipment might end up being higher than anticipated.

For instance, it increases when the room’s total area is less than 2000 square meters since it is more practical for masters to work with big volumes in such a setting. When it comes time to install lighthouses, surface preparation will also cost extra. The only way to place slopes is by hand, and this requires paying the masters separately. Frequently included in the cost is also:

  • Time for moving, costs for delivery of equipment;
  • time to prepare the device and its washing after work;
  • The cost of installing plaster corners.

The owner should also factor in the cost of electricity, which can add up when employing strong plastering installations. Because of this, the cost of mechanical and regular plaster may be comparable.

Equipment manufacturers and their products

Plastering stations and the excellent quality pFT stamps from KNAUF (Germany) are the most popular. The PFT G4 380 model, for instance, can spray up to 6-65 liters of plaster per minute, serve up to 50 meters (or 30 meters vertically), and operate at pressures of up to 30 bar.

Although the PFT Monojet brand device is less expensive, it has less impressive features: Performance: 15–35 liters per minute, feed up to 26 meters, pressure up to 15 bar. All of the equipment is compatible with standard networks, however some devices are multi-hollow (220V/380V). Up to 250–300 thousand rubles in price.

Other renowned producers of plastering supplies are taken into consideration:

  • Putzmeister;
  • Novo;
  • "Typhoon";
  • "Meteor";
  • "Century";
  • "Hermes".

The Afalin station, which is also used to fill the floors, is noteworthy among household plastering tools. The Afalina ShM-30 machine, for instance, is highly functional, autonomously kneads plaster in a designated container, and has precisely programmed component proportions. The machine performs admirably, has several nozzles, and quickly covers a sizable portion of the walls, floor, or ceiling in plaster. The only drawback of the car is its size, which makes servicing it a little trickier than with imported models.
