Mechanized plastering

Mechanized plastering Mechanized plaster - application features and what is needed for the process

Plaster is a universal method of preparing walls for decorative type finishing. At the moment, many formulations are used for such work, which are rather difficult to apply by hand. To speed up the process, most wizards use automated devices. This approach has many advantages and nuances, which are important to know about in advance. Let's consider everything related to mechanized wall plastering.

Features

Mechanized plaster is a relatively new way to apply the composition to the wall surface. it is based on the use of special devices that are capable of supplying the mixture under a certain pressure through special pipelines.

Technically this procedure assumes that all kinds of compressors and motors will be used. But the quality of application to the surface of the walls by a mechanical method will depend on various criteria:

  • Surface adhesion - certain types of walls cannot be covered with plaster without initial preparation. Brick, concrete or aerated concrete walls are ideal for such work.

  • The consistency of solutions - this factor is one of the most important. Please note that the mixture should not be very thick, because this increases the load on the engines, and can also lead to the failure of the device.

Interestingly, machine application is much better than manual plastering. If you use the classic approach, it will take a relatively long time. In this case, the old layer of plaster already dries, until the new one has time to gain strength.

Through automatic application, it will turn out to create an almost identical layer of the solution, which is much easier to work with in the future.

The mechanized plastering method is a universal approach that allows you to handle all kinds of surfaces:

  • External walls of buildings.
  • Decorative varieties of arches.
  • Window / door slopes.
  • Ceiling and walls.

Machine type of processing is a universal method for obtaining a high quality surface in a relatively short time.

Advantages and disadvantages

Mechanized methods of plastering are currently replacing manual application of the solution. this is due to several tangible advantages of such works:

  1. Mechanized plastering A high degree of productivity - in the modern construction market there is automatic devices that use methods to apply at least 1 cubic meter of solution per hour. Depending on the thickness of the layer, you can easily plaster walls with an area of ​​40 to 60 cubic meters per shift.
  2. Quality of Application - Plastering "pistols" apply the composition much more quickly than a simple scoop.

    At first, the surface will turn out to be almost perfectly flat, and it also requires only minor adjustments, which can still be done by automation systems.

  3. Creates a high-strength bond between the base and mortar. this is achieved due to the uniformity of the distribution of the layers, as well as the uniform supply of the composition. With this approach, the solution can get into almost all the cracks, filling them almost completely. This can be achieved through manual methods is almost unrealistic.

  4. Relatively small expenses - several people can apply the mixture at once, and in order to achieve this productivity manually, it is necessary to increase the number of employees several times, which can greatly affect financial expenses.
  5. Reduction of plaster costs - this is achieved due to the fact that the mixture will lie flat on the wall surface. Almost all products are used for their intended purpose, making it possible to cover a much larger area than with a manual approach. According to user reviews, automatic devices will reduce consumption by about 1.5 times.

  6. Relatively low price of plaster compositions - this indicator can differ depending on the structure of the wall surface on which the compositions are applied, as well as the manufacturer.
  7. There is no filling - the cement mortar perfectly fills all the cracks, which will exclude the primary wall treatment.

The use of equipment for mechanized plastering makes it possible to simplify repair tasks. But this is not a universal method, because there are several tangible disadvantages:

  • The high price of equipment - for this reason, this method is very rare in household construction. But if you are already engaged in such activities at a professional level, then the tool can quickly pay for itself.

    For one-time plastering, it is much better to hire specialists who have all the necessary equipment.

  • A high degree of performance of the device requires a constant supply of mixture and water. For this reason, it is advisable to have a water connection so as not to halt the process.
  • Strict adherence to recommendations when preparing a mixture. If you decide to add some kind of impurity, then there is no guarantee that the device is capable of effectively applying the resulting solution.

Mechanized modern devices for applying plaster compounds are a universal solution. This has resulted in incredible proliferation across a large number of construction sites where wall processing can be done at multiple locations at once.

Mixtures

The main parameter, on which the quality of the mixture for processing will strongly depend, are plaster mixes. Conditionally, they can be divided into wet and dry. The second type of product is used by large construction companies.

They will receive a ready-made mixture, which will be delivered to them by concrete mixers.But the main ones in the construction market at the moment are dry mixes, which allow you to get plaster compositions with your own hands. By the type of composition, dry products can be divided into a couple of large groups:

  1. Gypsum plasters - the main binder here is the simplest gypsum, and since the material absorbs moisture perfectly, it should be used indoors only with a small humidity. The unique quality of gypsum plasters is the high drying rate. This makes it possible to obtain a high quality surface for decorative cladding already after a couple of days after application.

    The mixtures have a high level of porosity, reducing the consumption of the composition several times in comparison with cement compositions. During application by means of automated devices, it is possible to obtain an almost flat ideal surface that needs minimal processing.

  2. Cement-sand plasters. Mixtures of a universal type that can be applied to almost all surfaces. Since the substance perfectly tolerates temperature changes, as well as the influence of water, most people try to use it for facade decoration of houses.

    If you are planning to build a pool, then this type of plaster is still an ideal option. The disadvantages of such products are the drying time and the uneven structure of the layer on top. For this reason, after application, the plaster must be additionally smoothed out in order to obtain a solid and even base.

Brands

The modern market offers many varieties of semi-dry and dry mixes, and among this variety we suggest choosing a couple of popular brands.

"Prospectors "

Mechanized plaster with such a mixture based on gypsum is capable of having high adhesion qualities.

It is designed for application on various types of surfaces, among which brick, foam block and concrete are ideal. Among the positive qualities, it will be possible to highlight the ability of the solution to transmit air and keep the heat inside the house. The manufacturer says that the composition can be used as a mixture for final finishing.

" Knauf"

This company has become one of the leaders in the production of finishing mixtures for various surfaces. It is required to note its gypsum compositions for plastering, which contain various polymer additives.

Among the features of the material, it is possible to distinguish a high level of plasticity, as well as adhesion to various surfaces. The range of color mixes includes not only gray, but also pink shades.

Equipment

The composition is applied using special devices that are mechanized. Depending on the method of feeding the solution, they can be divided into 2 main groups:

  • Mechanized plastering Auger apparatus - the main system elements there will be an auger that can grab the solution and move it in the desired direction.Such machines can be compared to classic meat grinders.

    But they are fully distinguished by their enormous power, as well as the degree of performance. A hose is connected to such a system, which is supplied to the place of work.

  • Pneumatic devices are generally fairly simple designs. The main tool here is a hopper (that is, a bucket), to which a hose is connected, in which air is compressed. Atomization of the manufacturer is due to the high velocity of the gas, which will push the solution through several or one orifice.

    The disadvantage of the device is that the plaster must be prepared separately and in large quantities. Certain devices are not practical and comfortable. For this reason, their use is justified for living conditions.

All such devices can be used to apply the mixture to floors or walls. We propose to consider in more detail the principle of operation of the auger-type apparatus:

  1. It is required to pour the solution into a special mixing compartment for mixing, and it is important to note that both prepared products and individual components can be used.

    The number of liquids and other products must necessarily correspond to the recommendations of the manufacturer or craftsmen.

  2. The system will then feed these components into the mixer, and mixing will take place within it for a long time.
  3. When the compound is ready, it will be gripped by the auger and fed into the hose. There will be a high pressure which forces the solution to move towards the outlet. On contact with the sprayer, the plaster will come out at a certain speed, and then stick to the base.

Please note that such processes are fully automated, and it is only important for the operator to connect a water hose to the system, and also timely filling of components for the future solution.

At the moment on the market it will be possible to single out several of the most famous branded mechanisms for applying plaster:

  • Knauf - machines from such a company differ in their small size, and the main purpose is the application of a plaster layer. But through them, you can also paint.
  • Afalina - a striking representative of this brand is the ShM-30 model, which is capable of working with different types of solutions. For this reason, with its help, it will turn out not only to plaster the ceiling or walls, but even to fill the floors.

  • UShM-150 - a small mechanism that is recommended to use if you need to level the bases. Certain modifications can work with paints and varnishes.

Now about the workflow.

Recommendations

Mechanized plaster gives high quality indicators. To achieve them, you need to be guided by several simple rules:

  1. Walls can be processed only in rooms where the temperature does not drop below +5 degrees.

    For this reason, in winter, work is carried out only in heated rooms, so that you can have control over the microclimate.

  2. Apply the mixture from top to bottom - pay attention that such operations are done manually in reverse. If external facades are being processed, then they need to be additionally reinforced with a reinforcing metal mesh.
  3. For leveling screeds for wallpaper or painting, it is necessary to pre-treat and putty plaster. This should be done a couple of hours after applying the mixture.

    To simplify the task, it is required to wet the materials in advance with water from the sprayer and let it soak. This will soften the mortar and allow it to be spread evenly and easily.

The method of applying plaster is simple and only needs to be carefully and properly followed. The choice of high-quality tools will be important, allowing you to apply the plaster in a convenient way, as well as following clear steps in the process. If you take into account all the tips, then the coating applied by this method will be durable and of high quality.
