The floor screed must be done if the floor in the room is uneven or its level does not correspond to each side. This is quite common when the concrete is poured incorrectly at the initial stage of construction. The presence of this discrepancy makes further installation of the floor covering impossible. The best option for leveling the floor is considered a semi-dry mechanized screed, for more details see https://altpol.ru/mehanizirovannaya-styazhka-pola/ .
In addition, you will have the additional opportunity to install a heated floor in the room. To do this, you need to make several ties. One of which is done after a layer of insulation, and the second after the wire is laid to heat the room.
There are screeds:
- Cement-sand - this is the most common type of screed. Its indisputable advantage is its low cost and fairly simple installation work.
- Semi-dry screed - differs in that it uses a non-reinforcing mesh with fiber fiber to strengthen it. The process of performing a mechanized semi-dry screed is presented in the video:
- Dry screed - a variety that is not very popular, although the speed of work with this type is the fastest. A solution that is crumbly in structure is simply poured, on top of which gypsum boards are installed. - Self-leveling screed - Created by pouring a thin layer of the floor, which is then leveled and hardened.
- Combined - used with several types of ties. In order to start working on the floor screed, it is necessary to level the level by placing beacons, and fill the floor with a self-leveling screed. Over time, cement mortar is poured between the beacons, leveling the level along them. Moisten the floor after a while to avoid cracking. Then the lighthouses take out and fill the cracks with the remains of the solution. After a few weeks, it will be possible to walk freely on the new floor.
