Plastering walls is a crucial part of building because it gives interior and external walls a smooth, long-lasting surface. This is accomplished by using a variety of wall plastering units, each made to handle particular materials and tasks. Plastering work can be made more efficient and of higher quality by being aware of the different types of these units and their working principles.
There are various types of wall plastering units, such as manually operated and machine-operated models. Plastering by hand requires a plasterer to be skilled and precise because it uses traditional tools like trowels and hawks. Conversely, machine-operated units require less manual labor because they automate a large portion of the process, producing results that are reliable and high-quality.
The plaster mix is normally held in a hopper and forced through a hose to a spray nozzle by a pump in the operation of machine plastering units. When compared to manual methods, this technique guarantees a uniform application of plaster on the wall while requiring less time and labor. More flexibility and personalization are possible with certain sophisticated units because they have programmable settings for regulating the plaster’s thickness and flow.
Construction professionals can accomplish better finishes more quickly by selecting the appropriate type of plastering unit and knowing how it works. The secret is to match the equipment to the particular requirements of the job, whether that means using machine-operated units for larger projects or manual tools for smaller, more detailed tasks.
Type of Wall Plastering Unit | Operating Principle |
Manual Plastering Unit | Uses hand-operated mechanisms to apply plaster manually. Suitable for small areas and detailed work. |
Automatic Plastering Machine | Powered by electricity or battery, automatically applies and smooths plaster over large surfaces. Ideal for high-speed and efficient plastering on large projects. |
There are several varieties of wall plastering units, all of which are intended to simplify and boost the effectiveness of plaster application. The fundamental idea behind these devices is to mix and pump plaster via a hose to a spray nozzle, which then evenly distributes the substance across surfaces. The objective is to achieve a smooth, consistent finish with the least amount of time and effort, whether using a fully automatic, semi-automatic, or manual plastering unit. Knowing the various kinds and how they operate can help select the appropriate tools for particular plastering applications, guaranteeing excellent outcomes for building and remodeling projects.

Composition and operating principle
The components of a full plaster application machine station include:
- receiving hopper;
- mixing spiral;
- mixing chamber;
- screw pair;
- engine;
- water pump;
- water flow indicator;
- air compressor;
- mortar gun;
- hoses: mortar, air and water;
- control panel;
- electric cable.
- Turn on the water.
- Fill the mixing chamber halfway with water.
- Do a test run of the station on water (without mixture).
- Pour the dry mixture into the receiving hopper.
- Turn on the device.
- In the mixing chamber, the mixture is thoroughly mixed with water using a spiral.
- The rotating auger pair feeds the finished solution into the hose.
- Use the water supply regulator to set the required consistency of the solution.
- Use the mortar gun to spray the mixture onto the prepared surface.
- Level the applied mixture with a rule.
- After finishing the plastering work, wash all the elements with water.
Note: The preparatory steps (setting up guide beacons, applying special compounds to prime the surface, and using a rule to level the applied composition) are the same as when plastering by hand.
Types
Based on factors such as power, productivity, receiving hopper capacity, and solution supply range, all plaster application mechanical stations are categorized into three primary groups:
- Professional high-performance plastering units.
- Universal medium-power units.
- Hopper buckets.
Any plastering unit, regardless of power and design, has the following benefits:
- high productivity;
- reduced terms of plastering work;
- minimal use of manual labor.
Professional plastering units
Such devices are intended for use at large construction sites. The unit"s power is 5.5 ÷ 7.5 kW, the capacity of the receiving hopper is 4 ÷ 7 mᶟ, the productivity is 4.5 ÷ 6 mᶟ/hour. Depending on the power of a particular model, the finished solution can be supplied horizontally at a distance of 10÷300 m, vertically – 35÷130 m: which will allow them to be used even in the construction of multi-storey buildings. The products are designed to work with any solutions (the maximum fraction size can be 6 ÷ 7 mm). The cost of such devices is 570,000 ÷ 850,000 rubles. Models from various manufacturers: "Salut SHS-4 / 6-3" (Russia), "PFT G5 Super" (Germany).
Universal units of medium power
This category’s unit’s power fluctuates between 1.5 and 2.5 kW. The solution is provided 10 × 25 meters away in both vertical and horizontal directions. The output ranges from 12 to 24 liters per minute. These units range in price from 150,000 to 350,000 rubles.
The Novator plastering station is one of this category’s most well-liked models. Features: 2.2 kW of power, 13 ÷ 14 l/min of productivity, and a 10-meter solution supply hose. Even in a passenger car, the device can be transported to the work site due to its small size and light weight (roughly 100 kg). Expense: 190,000 rubles (180,000·).
Hopper buckets
The simplest, yet most efficient, tool for mechanically applying solutions to walls and ceilings is a hopper bucket. What’s in a plastering hopper bucket:
- a metal container for the solution (capacity about 9.5 kg) with nozzles-injectors installed in it for spraying the mixture (usually 4 pieces);
- handles with a connector for connecting an air hose and an on/off valve for air supply.
Two varieties of these devices are made by manufacturers: wall-mounted models, which cost 5600 ÷ 6200 rubles, and ceiling-mounted models, which cost 6500 ÷ 7200 rubles. The nozzle locations distinguish them from one another. Because the nozzles are made to work with mixtures that use sand with fractions as small as 6 mm, all you need to set up a plastering station for sand-cement mortar is a ladle and a compressor (which you can rent).
Crucial! The description includes information on the air pressure that is supplied to the bucket. It is essential to use a compressor with enough capacity for effective use.
Such a device is very easy to use and doesn’t require any specialized technical knowledge:
- Prepare the solution using a concrete mixer or a construction mixer.
- Connect the air hose to the handle-holder.
- Fill the bucket with the prepared solution.
- Bring the bucket to the prepared surface at a distance of 5÷10 cm.
- Press the air supply valve.
- Spray the solution onto the wall.
- Fill the bucket with the solution again and continue plastering.
- After finishing the work, lower the bucket into a container with water and supply compressed air.
- The hopper bucket is cleaned and prepared for storage, transportation and subsequent work.
In contemporary construction, wall plastering units are revolutionary because they provide consistency and efficiency that traditional techniques just cannot match. These devices ensure a consistent application on large surfaces while saving time and labor by automating the plastering process.
Choosing the appropriate tools for your project is made easier when you are aware of the various wall plastering unit types and how they work. There is a plastering unit made to fit your needs, regardless of the size of the construction site or the small-scale renovations you’re working on. The primary varieties consist of fully automatic, semi-automated, and manual machines, each with unique features and advantages.
Plaster mix must normally be loaded, the required thickness must be set, and the machine must be guided along the wall to operate these units. To make things even easier, some sophisticated models have remote control options and programmable settings. To guarantee these units last a long time and function at their best, proper maintenance and routine cleaning are essential.
Adding wall plastering units to your construction process can improve output and quality dramatically. You can accomplish smoother, more durable finishes and finish projects more quickly by investing in the right equipment and learning how to use it. This will ultimately increase customer satisfaction and spur business growth.
