How to level a concrete floor after filling the bearing

Nowadays, in almost all buildings, regardless of their purpose, a cast-in-place concrete underlayment with metal mesh reinforcement is used as the base for the finishing flooring. However, after the screed solidifies on the surface of the cast-in-place concrete, irregularities in the form of waves, tides, shells, or protruding particles almost always remain. Therefore, the owner of the building often has a question: how to level the concrete floor under the tile, laying laminate or other clean flooring.

Leveling concrete screed

In order to get an idea of ​​the methods of working with concrete, this article will discuss in detail the question of how to level the concrete floor and suggest the most common ways of doing this work.

In addition, detailed instructions on the use of various leveling technologies and methods for treating frozen concrete screeds will be presented here.

Dry screed

This method is the simplest, does not require the use of special equipment and large labor costs, therefore, it is widely used in arranging the finishing floor with their own hands in residential and commercial premises.

This technology completely eliminates the use of water in the process of work, so it is often used in cases of decking of laminate and other wood-fiber materials.

1. After complete solidification and drying, the surface of the monolithic slab must be thoroughly cleaned from debris and dust.
2. Lay waterproofing of thick construction polyethylene film on the prepared slab, wrapping its edges on the walls to a height of at least 100 mm.
3. If necessary, under waterproofing need to lay electrical or plumbing communications.. For the passage of walls and floors, you can apply diamond drilling holes in concrete using special tools.
4. Pour the dry granulated leveling mixture over the entire surface of the floor and distribute it in a uniform layer 50-80 mm thick.
5. Verify compliance with the horizon using a long building level and tamp with a manual tamper or vibration plate.

After compaction of the granulated pillow, the substrate is laid on the surface, on which the floor covering is mounted.

   Note! The positive features of this method can also include good thermal insulation, which is provided by the porous structure of the components of the dry granulated mixture.

Cement-sand mortar

This method is classic and due to the high strength of the finished coating can be used both in residential and in commercial or industrial premises.

It can also be recommended to those who are interested in how to level the concrete floor in the garage after pouring the monolithic slab.

1. Before performing work, clean the surface of debris and dust, then cover it with one layer of penetrating primer.
2. Using a gypsum mortar, fix the beacons with a distance of at least 1000 mm between them using a laser or water level and leave until the fixing solution is completely dry.
3. Prepare a cement-sand mortar in a ratio of 1: 3 not very thick consistency and start pouring from the corner farthest from the entrance.

1. Pour the solution into the space between the two lighthouses and, moving the rule along the lighthouses, evenly distribute it over the whole area.
2. Thus, step by step, you need to fill the entire floor area. If possible, the alignment of one room in one working day should be performed.

After the mortar has hardened to such an extent that it can be become on it, you need to carefully remove all the beacons from the finished floor, and wipe the cracks with fresh mortar.

Due to the low cost of materials and work, this method has the most favorable price-quality ratio.

   Tip! To prevent cracking of the leveling screed after pouring, it is recommended to cover the floor surface with plastic wrap and moisten it periodically for one week.

Self-leveling compounds

The floor leveling compound is a dry fine mixture of binder and filler, which must be diluted with water immediately before use and thoroughly mixed using a construction mixer or nozzle for an electric drill.

The finished mixture spreads out on the floor in a thin layer, and after drying it forms a smooth and uniform surface of high quality, suitable for arranging the finished floor using all types of household floor coverings.

1. This method is suitable for relatively even sex, so if there are significant irregularities, they must be fixed in advance. To remove protrusions or overflows, cutting of reinforced concrete with diamond circles can be used, and deep cavities and cracks need to be rubbed with a cement-sand mortar.
2. Carefully remove all dust and debris, then saturate the surface with a penetrating primer.
3. In a clean bowl, dilute the required amount of dry mix in exact accordance with the instructions on the package.
4. To distribute the finished solution over the entire area of ​​the floor and allow it to spread independently over the entire surface, then leave it to solidify completely.

After pouring such a coating freezes in half an hour, however, it is possible to carry out any work indoors no earlier than in 3 days.

   Tip! Such preparation of the floor is suitable only for the subsequent laying of the finishing covering. Hardened surface can not be painted or used as an independent finishing floor.
