The machine is trowel on concrete. Double rotor trowel

Arrangement of the floor must be carried out very qualitatively and responsibly. Only in this case you can achieve an ideal floor surface, which will last a long time. During repair or construction, various tools are used to treat the concrete screed, including the trowelling machine.

Device unit

The presented product has such basic elements:

1. Trowels. These components are most often made of very strong stainless steel and have a rectangular shape. The edges of the blades are usually bent upward. If these elements are combined, the edges can be bent under different radii. In order for the blade to lock onto the machine, special fasteners are placed on it. The number of these items depends on the type of device. For example, if the machine is a trowel one-rotor, then they can be 4, if 2-rotor, then 8. To protect against the harmful influence of external factors, the blades are treated with special lubrication.
2. Trowel disc. Thanks to metal fasteners, it can be quickly and securely fixed on the blades. In two-rotor vehicles, it can be reversible. The disc for the trowelling machine has a thickness of 2 to 3 mm.

What is the apparatus for?

If you want to make a really high-quality floor, the trowel machine must be used necessarily. It is used for the processing of concrete, semi-dry screed, harzovki.

This procedure is necessary to strengthen the leveling layer. The fact that after pouring concrete on its surface is a liquid - "milk". It can provoke stratification of concrete. Therefore, in order to avoid such a situation, it is better to treat the screed in time. For this purpose the trowel is used.

Operating principle

The trowel works very simply. Grinding wheel and blades frequent turns (while the user sets the speed of rotation of the element and presses it on top) rubs the material of the top layer of the screed into its "body". In order to increase the efficiency of work, you can change the angle of the blades.

The machine is able to eliminate even the largest irregularities. This machine will help you make a perfectly smooth base. The disk grinds the surface, and its blades smooth it.

Types of machines

The trowelling machine for concrete can be classified as follows:

• Petrol. The advantage of this option is that the device is able to operate autonomously. This means that it can be used in an open space, without being tied to the electrical network. Inside the room, this model should not be used - exhaust fumes can lead to poisoning.
• Electric trowel. It is connected to a standard power supply network. It is used in closed premises. The device is intended for a small amount of work.

It is possible to classify this equipment according to the peculiarities of use:

1. Pristenochnoe. Such equipment has small dimensions and is used in those cases when the use of a standard machine is difficult (corners, a place near skirting boards, doorways are processed).
2. One-rotor. This type of product is the most common.
3. Two-rotor trowel. This device has the maximum possible dimensions, so in an ordinary apartment it will be extremely inconvenient. Most often, the device finds its application in large-scale construction or in the repair of large-area premises.

Features of device selection

If you need a trowelling machine for concrete, you can purchase it in a construction shop. However, in order to choose the correct option, it is necessary to take into account some parameters of the device:

• Frequency of application of the device. If you do not earn repair of apartments, then buying this equipment does not make sense. Nowadays it can be simply rented.
• The size of the area to be treated. The choice of type of machine depends on this. If you have a large area, then a single-rotor device is unlikely to cope with work.
• Complexity and features of the layout of the room. In addition to the standard device, you will also need a wall-mounted version, since in any room there are corners and doorways.
• Engine power. For small and infrequent works you can buy a low-power machine.
• Type of energy carrier. The electric version is suitable for enclosed spaces, and gasoline can be used for the treatment of outdoor areas.
• Band width. Here, the choice, again, depends on the size of the room.

In addition, you have the opportunity to use additional attachments of a larger size. Although the twin-rotor trowel eliminates the need to do this.

Popular manufacturers and cost of the device

If you decide to purchase the device presented, it is important to find out who produces such equipment. In the market now you can find many Chinese models that are relatively inexpensive. However, not all users comment on them positively. The cost of such a product begins with a mark of 25 000 rubles. However, it should be borne in mind that after several uses it can break.

The most popular and high-quality equipment is the American one. Here the choice is big enough: Whiteman, Bartell, Boren, Allen. The products of these manufacturers have long been a leader in the world.

Kreber equipment is in demand and of high quality. Here you can choose and kromochnik, and one- or two-rotor apparatus. Also no less popular is the company Coopter, as it produces universal devices.

If you need a trowelling machine for screed, its price varies between 25-250 thousand rubles. However, to choose a device at a cost is necessary taking into account all the above parameters. Perhaps you do not need an expensive device.

How is grouting carried out?

This work needs to be approached responsibly. It is conducted in 2 stages:

• The first should be carried out no earlier than 4-20 hours after pouring the screed. You can carry out the procedure if the person's leg loads in concrete only 2-3 mm. This is a rough ground trowel.
• Finishing the surface. It is carried out after the coupler has darkened, stops getting dirty, and presses. By means of the machine, a special dedusting agent can be rubbed into the concrete layer. It additionally strengthens the surface of the screed and prevents the appearance of chips (cracks).

If during the work you will use additional substances to harden concrete, then grout should be made immediately after the surface of the layer absorbs moisture. The composition should be distributed throughout the entire area of the room evenly. Initially, 2/3 of the whole mass of the composition is rubbed. After a while, the remaining part is rubbed.

Safety precautions

If you follow the simple rules of handling the device, you will be able to protect yourself not only from injuries, but also from premature equipment breakdown. During work, you should be most attentive. A person must wear protective clothing, gloves and glasses.

On the desktop should not be unnecessary things. Do not work on the machine to those people who have not been instructed in safety or do not know how to use the equipment. The device must be fully tuned and serviceable. This should be checked before work. That's all. Good luck!
