Screed for the floor: what is it, photo wall, how correctly to make the national team, in the apartment itself, plaster correction
now in order to align the subfloor and then carry out finishing, you must first carry out installation of the screed. A couple of decades ago, the simplest sand-cement mortar was used for this purpose, and now there is an incredible amount of materials and methods for leveling the floor.
What is the tie and what it should be
What screed floor( rather than a bow tie or a body) - the most common option, through which you can warm and dignyat subfloor. Modern flooring materials or, in other words, technology, high demands on the floor surface, on which the installation will be carried out.
To properly make a screed in the apartment itself, you need to pay attention t
- The floor must be smooth, horizontal and smooth. The allowable curvature is 0.2 mm per 1 m.
- The floor must be strong, stable and free of cracks.
- Tightening must be selected thermally insulated.
- A waterproofing of the floor is mandatory before the screed.
For leveling the floor with a screed, different technologies can be used, each of which has its own distinctive features. In addition to the classic cement mortar or wet screed, there are a number of floor levelers - semi-dry, dry and self-leveling.
In general, all equalizers have the same goal, but technology may differ.
With your own hands, you can make the floor of the house even if you follow the step-by-step instructions, as well as a competent selection of the screed. Screeds can differ in strength, durability, surface quality and thermal conductivity. In addition, screeds can differ in the complexity of the process and the way they are arranged. Depending on the complexity of the work and the quality of the final coating, the cost depends.
How to make a screed flooring and that it is
As a rule, if the question comes from a man that is a screed floor, and for what it is, it indicates that he has absolutely no idea, What it is and about the purpose of its use.
This process is considered very important and requires special attention and professionalism at work.
Naturally, this does not mean that doing the floor in the hallway, or any other room can not be yourself, just follow the previously more familiar withAll work thoroughly. It is equally important to study the properties of the material and the floor, which will be leveled. The choice of materials depends on the state of the floor.
ties are made in various forms, but usually for apartments and private homes purchased:
- The cement;
- Filling floor;
- Dry leveling floor.
Each type is characterized by application technology and price, including the complexity of installation, the cost of time and effort. It is hardly possible to say boldly what kind of screed will be the most suitable, since each of them has its own assigned task.
For example, if the room there is a strong difference of planes, it is best to strictly correct operation of the floor is held, so are excluded anhydrite screed, in which gypsum sheets used. Self-leveling floors can be stacked in places where the difference is a maximum of 5 cm.
Instruction: how to properly make floor screed
How is it better to make a floor installation by laying the screed? It is important to note that the alignment of the street floor is significantly different from the home one, as it is possible to carry out work inside the premises at any time of the year and without worrying about precipitation.
In any case, you must do a series of actions to help intelligently laid screed.
- Correctly evaluate the condition of the base of the floor. If the old coating is cracked or it is a finishing material, it must be removed.
- Then the method of work is chosen. Here we take into account the costs of forces, time and money for leveling the floor.
- A suitable composition is selected.
- After applying the screed, you need to wait a long time to completely dry. Otherwise, its integrity may be violated, and at some point it will crack.
Modern screed on SNP is in high demand and is famous for its excellent quality, but its popularity does not lose the old antiquated way of laying the mixture in which there is a conventional cement and concrete. All the work will be divided into 3 parts - the arrangement of beacons, the preparation of the mixture and the laying of the screed.
Compliance with the order of stages is very important, since it is impossible to first prepare the mixture, and then start installing beacons, or completely eliminate their use and simply pour the screed.
The bottom line is that the mixture of concrete dries too quickly, and a special skill is required to install beacons that help level the screed. That's why newcomers are recommended careful compliance with the phasing.
Custom team screed
There team plate, which is made of large-sized sheets of plywood, gypsum fiber webs, plasterboard, fiberboard, chipboard and LSU.The screed fits in the yard and inside the house, but it is used not for walls, but solely for the floor.
- Must be rough;
- Can not be floating;
- It becomes durable.
The sheets are laid out on the prepared and leveled surfaces in a horizontal view. As a base, use rails of wood or plastic, which must be as firmly attached to the base of reinforced concrete as a CBT device, and they are installed, immediately aligning on the base.
As for the screed itself, it is bulk and has been in great demand lately.
The floor is increased on average by 40 mm, and the thermal insulation material is laid between the lags in the openings. In the dry screed there are no wet processes, and once the installation is completed, you can start the finish. The only drawback of this screed is the lack of resistance to moisture.
Strong plaster screed
The choice of gypsum floor screed is possible under certain conditions - if it is necessary to carry out repairs as quickly as possible, if there is no possibility to wait until the wet or semi-dry fill dries up, if the old building is reconstructed, where the floors between the floors are made of wooden sheets, And they are not able to withstand a lot of weight. If you want to work at temperatures below freezing, it is necessary to carry out the installation of underfloor heating in the room where it is permitted to use only dry screed and for installation of the floor in the cottage or high-rise office building, use gypsum.
have dry screed has its merits, and they are as:
- Excellent fire safety, as the gypsum does not burn;
- Good sound and heat insulation;
- No release of toxic substances and fumes;
- Quick installation;
- Convenient installation, as it is possible to lay all sorts of communications in the process of leveling the floor;
- Possibilities of maintaining a distributed load of up to 1000 kg / m2.
The gypsum screed has its drawbacks. The gypsum screed is literally afraid of water. If the moisture gets into the screed, the filler will get wet and because it is airtight, hidden under the finish finish, a smell of dampness and even mildew will soon appear. Plates of gypsum fiber can deform from non-evaporating moisture, which will make the floor uneven.
If the screed is impregnated with moisture, then it is necessary to open the floors and carry out the work again.
The installation of the screed is done in a special outfit, in particular when there is a gas mask. Unlike other screeds, this costs too much. No compositions are added to the gypsum screed, in particular PVA glue, since it is performed exclusively on dry plaster.

Specialists do not recommend choosing a screed independently, as it is best to invite a craftsman who can correctly assess the condition of the floor and choose the best option for finishing. Only in this case on monolithic ferro-concrete floor it is possible to lay a coupler without defects.
