It is possible to quickly and efficiently prepare an outdoor base for the finishing coating using a mechanized floor screed quality and the appearance of the floor covering depends on the competent preparation of the base for repair. The most affordable and effective way to create a solid and even base is the use of semi-dry screed. It is possible to simplify and speed up the technological process of laying a screed using special machines. What devices are used to fill semi-dry screed, and what stages include fill technology - read below.
Mechanized screed: Advantages
Modern technology of the mechanized screed allows you to achieve a smooth surface on any, even a whimsical, base in an absolutely any room. As a result, a smooth, smooth surface can be coated with any finishing floor material (linoleum, tiles, parquet, etc.).
The advantage of a mechanized floor screed is that it is effective and accessible to everyone
Unlike most of the methods for the reconstruction of the floor, the mechanized screed has such advantages:
- High performance and reduced labor complexity. Thanks to the application of special equipment, time and power spent on the processes of preparation, transportation, laying and grinding material are reduced. At the same time, the quality of the screed increases significantly.
- Availability and efficiency. Components that are used to prepare a solution (fiberglass, sand and cement) guarantee the strength of the coating. At the same time, their cost is low, and it is possible to find materials in any construction store.
- Fast hardness of the material and the absence of shrinking cracks. The technological process involves the use of a small amount of water for the preparation of the mixture, which quickly evaporates. This accelerates the curing process of the screed and minimizes the occurrence of cracks in the coating (during evaporation of water, the cement sandy mixture can occur). In addition, moving along the coating in special shoes can be just a couple of hours after laying.

It is also important that the solution for a semi-drying screed is prepared on the street and is fed to the place of work on special sleeves. Due to this, it is possible to avoid pollution of the room with dust from bulk materials, splashes from the solution.
Machine screed floor: technology
The technology of performing a semi-dry machine screed is quite simple: anyone can master it, even it can not even have construction experience. To perform independent work, special equipment will need, which in a wide range offers construction stores.
Before proceeding with the mechanized screed, you should first prepare the surface of the floor
The process of repairing the floor and the preparation of the foundation for the finish finish has such steps:
- Cleaning the floor from garbage and dirt, repair of cracks, primer surface.
- The height mark of the screed with a laser construction level.
- Preparation of the working mixture. The solution is bred in a concrete pump bunker. At the same time, the work should be performed at a temperature of at least -5 degrees. In the camera of the apparatus, the ingredients for screed are loaded in this order: sand, fibrovolok, cement, water with a plasticizer.
- Laying screed. After filing, the mixture for filling the screed through the channels to the destination, it is smoothed manually using a rule with a length of 1.5-3 m.
- Grout surface. The screed is grinding with a special machine with disks, which eliminates irregularities and tubercles.
In rooms with draft, dry air and a large number of natural light, the screed should be covered with polyethylene for several days. If the room temperature exceeds 22-23 ° C, the tie is pre-moisturized.
Grouting machine for semi-dry tie
Machine semi-dry screed involves performing all the work using special devices (for example, such as concrete pump). Quickly achieve a smooth and smooth surface for a semi-dry scuster allows a rapid (grinding) machine.
For semi-dry floor screed, experts recommend using a special cloud car
The grinding machine makes it easy and quickly align the surface of the semi-dry screed. At the same time, the car has small dimensions and easy to use, which allows it to be used in domestic construction.
Choosing the grinding machine, it is necessary to carefully examine its characteristics: Unclear manufacturers often try to cover low machine performance by increasing the number of engine speeds, which leads to the speedy wear and tool output.

In order to get the maximum return on the application of the device, you should choose a typewriter with a power system (there are gasoline and electrical machines), the number of rotors (one-tone and courtyard), diameter and size of the rotor blade.
Wet screed: Views
Wet screed is a durable coating at an affordable price. Such a screed from the cement-sand mixture is prepared (suspended by shrinkage and cracking), plastering solution with plasticizers (increases the strength and life of the coating).
If you decide to make a wet screed yourself, then you need to make a mixture of sand and cement in advance.
The selection of the wet tie depends on the finishing material for the flooring. So, a knitted cement-sand tie is better suitable for the decoration of ceramic tiles. For laminate or carpet covering, the best way to prepare the base will be this option: concrete - liquid floor - waterproofing - plywood
ANDComing from the features of the preparation of the foundation for the finishing finish, distinguish:
- Knitted screed. This is the simplest laying option that can be easily made with your own hands, not even having a building experience (the screed is put on the slab immediately).
- Scientific with waterproofing layer. Waterproofing is laid under the screed on the base.
- Wet tie with thermal insulation. The thermal insulation layer is most often used on ground bases. It is placed on the sand, under waterproofing. At the same time, the screed itself must be performed on reinforcement. Laying on the tile base can be performed without a sandy layer.
- A tie with a bulk polymer coating. Such a screed is used to prepare the base for subtle, sensitive coatings (linoleum, carpet) as it gives the perfectly smooth surface without defects. The liquid floor is poured into a fully frozen concrete tie.
There are also self-leveling floors, for the installation of which the liquid mixture is used. Such a mixture is easily distributed without physical exposure. But, due to the lack of a screed, the service life of such a coating can significantly reduce.

The mechanical screed is a simple, fast and efficient way to repair and prepare the base for finishing coating with tiles, parquet, linoleum and any other material. The process of fill the semi-dry screed simplifies special machines, which can master which any person can. Therefore, it is possible to use this method even for domestic construction with your own hands. Perform the consecutive steps described above and you will get even, durable base for the finish!
