Equipment for mechanical plastering

Plastering walls has never been the same thanks to mechanical plastering, which provides a quicker and more effective substitute for manual techniques. This method reduces manual labor and saves time by using specialized equipment made to handle large surfaces with ease.

To get a smooth, even finish, mechanical plastering requires knowledge of the proper equipment and tools. Every piece of equipment, from plastering machines to mixing pumps, is essential to ensuring that the task is completed accurately and quickly.

This post will discuss the many kinds of machinery used in mechanical plastering, their purposes, and how they can improve efficiency and professionalism in the plastering process. Gaining the most out of your plastering projects depends on your familiarity with these tools, whether you’re a seasoned contractor or a do-it-yourself enthusiast.

Equipment Name	Description
Plastering Machine	Automates the mixing and spraying of plaster onto walls, increasing efficiency and reducing manual labor.
Mortar Pump	Pumps plaster mix through hoses to the plastering machine or directly onto the wall surface.
Spray Gun	Used to apply plaster evenly across large wall areas, ensuring a smooth finish.
Mixing Drill	A heavy-duty drill used for mixing plaster to the right consistency before application.
Compressor	Provides the necessary air pressure for the spray gun to function correctly.

What is it?

Plastering equipment includes mortar pumps that automatically mix and apply the mixture. These labor-intensive tasks were previously completed manually; currently, workers are not involved.

Under pressure, the solution is applied to the surface and dispersed uniformly.

First and foremost, mechanical plastering of walls has received positive feedback for the final coating, which is smooth and uniform and ultimately helps reduce puttying effort.

This process can be used to finish both inside and outside the building. The best choice for surfaces with striking sections is this one.

Advantages and disadvantages.

An additional benefit is that the process is already automated. Nevertheless, in addition to this, the following benefits of mechanical plaster application stand out:

♠ reduction in material usage. The mixture is saturated with air bubbles by a unique mixing technology, increasing its volume. Furthermore, the apparatus disperses the solution uniformly by applying it in a thin layer. Because mechanical plastering uses half the amount of materials when compared to manual plastering of the same volume, it is deserving of positive reviews.

Simple computations can be used as evidence. Plastering mechanically uses a maximum of 14 kg of solution per square meter, whereas applying plaster by hand uses 16 kg of solution for the same area. The savings are 2 kg per m^2. Additionally, each square meter of the treated area yields two times three, or six kilograms, of plaster, as plaster is typically applied in at least three layers.

A rapid completion rate. A mechanical device completes tasks far more quickly than a human, regardless of the area being treated. Calculations show that plaster is applied mechanically four times faster;

♠ Maximum adhesion (the amount of plaster that sets and penetrates the wall). Both feeding the solution under pressure and the fine-grained nature of premium building mixtures produce this effect;

♦ Savings on consumable costs. The cost of mixtures for manual finishing is significantly less than that of mortar for mechanical plastering. Their quality is far inferior, though. Upon automatic application, putty purchases are prohibited. Reduced consumption also makes savings apparent;

♠ the application happens multiple times quicker, resulting in a higher-quality final product;

♠ an adequate quantity of prepared composition. The solution needs to be prepared in small amounts when using a manual method because it dries out after 50 to 60 minutes. Plaster is applied automatically, allowing for continuous mixing within the device and quick preparation of the necessary amount. It will also stay homogeneous for a considerable amount of time;

♠ Ecologically friendly substances. Since the composition is free of harmful contaminants, hospitals, schools, and kindergartens can use it;

♦ Automatic equipment keeps future subsidence from happening as well as the appearance of streaks and cracks.

According to multiple reviews, the only disadvantage of mechanical plastering is the expensive equipment. It is therefore not the most prudent investment to buy it in order to finish an apartment. These costs won’t pay for themselves. In this case, renting the appropriate equipment or getting assistance from a qualified expert is more practical.

The choice of suitable compositions.

In mechanical plastering, mixtures of liquid and dry materials are used. Their material compositions also vary:

• Gypsum. Used for decoration indoors. Most often with their help, the walls of apartments (and even ceilings) are treated with their help). However, it is not recommended to use gypsum plasters in rooms with high humidity. The main characteristics: porosity, rapid setting;
• Cement-sand. Used for mechanical plaster in external facades. Are distinguished by special strength and resistance to extraneous influences (precipitation, temperature changes). Cons: the need for putty and a long drying time.

Both varieties of mixtures exhibit resistance to moisture and frost protection qualities. The effects of UV radiation do not cause them to degrade.

To boost plasticity and shorten the drying time, it is acceptable to add auxiliary ingredients to each plaster in addition to the primary ingredients.

How automatic application equipment works?

The components of plaster application equipment, an electric autonomous device, are as follows:

1. receiving hopper;
2. mixer for mixing;
3. feed system;
4. automatic control unit;
5. air compressor.

A control panel is a standard feature of many contemporary mechanical devices. This enables remote control of the operation. The device can be serviced by just one or two technicians (the ideal mode for no downtime). It can be disassembled if needed; every component is detachable. The plastering tools are ideally sized to fit in a passenger car’s trunk in this configuration. Transportation is now more convenient as a result.

When the system is connected to a typical city power grid (220 V), it functions. The design is built with corrosion-resistant, long-lasting materials to improve dependability and durability.

The device’s working principle can be broken down into multiple phases:

• the mixture (dry) is poured into the hopper, then it is dosed into the mixer;
• the required volume of water is added in accordance with the proportions (directly from the water supply). If there is no access to water supply at the construction site, then you can use a special pump that will deliver water to the hopper from any container. It is sold complete with a plastering machine;
• the components are automatically mixed in the mixer, and the finished composition is saturated with air. As a result, it loosens and becomes homogeneous;
• the compressor produces compressed air, with the help of which the composition is directed through a hose to the surface of the walls being treated.

Plaster cannot be automatically applied in a space smaller than thirty square meters. This is because the plastering device has impressive dimensions.

The equipment is a simplified form of mortar pumps. Another name for them is cartridge guns. Since they lack a mixer, when working with them, the solution must be prepared independently (manually).

For plastering walls mechanically in small residential areas, a pump is the best choice.

It is not always practical to use, though, as a fully charged gun needs to be held in your hands, unlike automatic equipment. Considering the weight of the structure, this is not so simple.

The plaster application device’s ease of maintenance is one of its main advantages. With a single hand motion, the mixing container is removed. After that, it is cleaned using regular running water. Two to three buckets of liquid should do the trick and be sufficient to clean the hose as well. Last but not least, installing the hopper is likewise simple.

Compared to traditional methods, mechanical plastering equipment offers faster application, more consistent results, and less physical strain during the plastering process. Plaster sprayers and mixers, among other tools, make it possible to cover even large surfaces quickly and effectively, saving money and labor. For both professionals and do-it-yourselfers who want to achieve a smooth, high-quality finish with the least amount of work, this contemporary plastering method is perfect.

Preliminary preparation.

The process of automatically plastering walls starts with preparatory steps. These are typically completed in the following order:

1. if there are any metal elements on the wall, they are cut off and treated with protective agents against corrosion;
2. before mechanical plastering, both facades and interior surfaces are removed from old coatings, mold and rust (if any) are cleaned off;
3. remove concrete drips and any protrusions the height of which exceeds 1 cm, clean the surfaces from grease;
4. degrease the coating with soda or a purchased solvent;
5. concrete, plasterboard, painted surfaces are characterized by a high degree of absorption, therefore, they are thoroughly cleaned from dust and must be treated with a primer;
6. all visible cracks are sealed (it is better to use a nylon net for this). The larger the area of ​​the site processed by automatic wall plastering technology, the larger the cells on the net;
7. with a plaster level at least 2 meters long, check the curvature in the vertical direction. For a similar horizontal analysis, use a cord with a template. The same check is carried out on the corners, using rules and templates. Based on the results, it is necessary to determine the most protruding place;
8. install beacons (on the outer corners). This will facilitate the alignment procedure.

Additionally, automatic plastering of external facades doesn’t start until the site preparation work is finished. First and foremost, the site must be cleared of construction debris.

Only when the outside temperature is at least five degrees can work start. The highest temperature that will allow the plaster to properly fix is thirty degrees.

Preparation of an automatic plastering unit.

Walls cannot be automatically plastered without the right equipment in place. Water is first supplied and it is connected to the power supply device.

When using a semi-automatic cartridge gun, workers must manually prepare the solution first. Fill the hopper with the dry mixture first. Next, dilute it with water according to the recommended ratios. Next, begin combining the ingredients.

Because it is continuous, a composition of exceptional quality is the result. As soon as the equipment is prepared, you can start mechanically plastering the walls.

The process of application to the wall.

The following guidelines should be followed when applying plaster mechanically to ensure a satisfactory and long-lasting outcome:

• always start with processing the corners. In this case, it is necessary to pay sufficient attention to the joints in all directions. Only after this do you start finishing the remaining area;
• the optimal distance from the hose (gun) to the area being processed is 20-30 centimeters. The plane being processed should be perpendicular to the outgoing stream;
• the higher the speed of the gun, the thinner the final layer of plaster will be;
• automatic plaster application should provide a perfectly smooth coating. Therefore, to prevent the appearance of indentations on the surface, each subsequent layer should overlap the previous one by 50%;
• the device is capable of directing the stream to a distance of 6 and 8 meters (in the vertical and horizontal directions, respectively). So it is convenient to process ceilings and walls even without using a stepladder.

Methodology for leveling the coating.

Automatic wall plastering inevitably comes to an end when the treated area is leveled and shaped. The applied composition is brought together with beacons as the main focus.

The surface starts to form 40 to 50 minutes after the end of the mechanical application (but not before 25 minutes) in order to achieve an absolutely smooth coating.

After plastering mechanically, you’ll need the following tools to level the wall covering:

• wide rules;
• construction trowels;
• large spatulas.

Excess plaster is scraped off the walls and reapplied throughout the space using the designated tool. Everything needs to be leveled off and tightly controlled.

The last step of the procedure begins when the coating has slightly dried. Using a sponge or specialized attachment, any last minute imperfections, bumps, and scratches are rubbed and sanded. The joints and all corners of these movements need to be completed with extreme caution.

Following this, the case can be formally concluded. It takes three to four days for the coating to fully dry. The drying period is extended to one week if the room’s humidity level is higher than 60%. After that, you can finish with other techniques like painting, wallpapering, and puttying (if needed).

Plastering walls has been transformed by mechanical equipment, which provides a level of efficiency and accuracy that is unmatched by traditional techniques. Purchasing the appropriate tools can save time and lower labor costs, regardless of whether you’re a professional contractor or a do-it-yourself enthusiast.

These tools, which range from mixers and sprayers to plastering machines, simplify the procedure and make it simpler to produce a uniform, smooth finish. Mechanical equipment makes application faster by automating much of the work, so large areas can be covered in a shorter amount of time.

In the end, the equipment you choose will depend on the scope of your project and your unique requirements. Even the most difficult plastering jobs become more doable with the correct equipment, producing long-lasting, excellent results.
