Preparation of a floor for a laminate: leveling of a wooden or concrete floor

When laying a laminate,characteristics and type of material, and the base of the floor. Therefore, preparing the floor for a laminate is a special process, which is given maximum attention. The whimsical nature of the laminate lies precisely in the surface on which it is laid. The presence of various cracks, tubercles and pits negatively affects both the service life of the material and the room as a whole. Therefore, preparation for laying the laminate should be done competently and efficiently. Laying the laminate requires a perfectly flat surface, so before you start the installation, be sure to level the floor.

Tools and materials needed for floor preparation

In order to prepare the floor as comfortably as possible, the following tools are needed: Scheme of cement floor screed.

Needle roller (only for bulk floor).

The building level is used to level the base. The best model is the laser model, which shows the minimum error, which is not available to the standard building level.

Rule. The longer it is, the better, because it will be possible to grab a large floor surface at a time.

Drill with mixer-nozzle is necessary for stirring the solution. If it is absent, you can interfere manually, using, for example, a board. But it will take more time and will bring less effect.

A spatula is a small analog of the rule.

Also, floor preparation requires certain building materials. It is necessary to determine what will act as a substrate: The scheme of leveling the floor with a moisture-proof plywood.

Cement screed (you need a construction dry mix, plaster and sealant). It is necessary for a concrete surface.

Wooden flooring (usually, as a rule, standard plywood is used to create a more even floor). It is used with parquet flooring or when the laminate is floored on linoleum.

It is worth remembering that all kinds of surfaces can be covered with laminate, except for carpet. Back to contents</a>

Aligning the concrete floor with a laminate

When the concrete floor is uneven, it is necessary to align it. How to prepare a floor for a laminate with a self-leveling mixture? Follow the steps: Scheme of leveling the floor with a self-leveling mixture.

• to carry out the purification works of concrete, it is possible to vacuum the base;
• cover with cracks in the screed (it is recommended to make it a tile glue);
• to bring down rushes and mounds;
• treat the floor with a deep penetration primer;
• prepare the mixture according to the manufacturer's instructions.

Despite the fact that the mixture is calledself-leveling, without human help it will not level. In order for the floor under the laminate to be perfectly flat, it should be poured over the beacons. Beacons are guides along which a rail or a rule moves, leveling the material and eliminating excess. at this stage is as follows:

• mixture is poured and leveled by the rule;
• a spatula distributes the solution;
• roll the mixture to remove air;
• The rule removes unevenness, after the mixture has hardened (1-2 hours).

Scheme of rough floor under the laminate. The consistency of the solution should be similar to sour cream. It must be made absolutely homogeneous. Pouring the floor under the laminate starts at the top of the floor, then the mass itself will already be distributed over the surface. Then the solution is spread by means of a spatula. There are a number of recommendations on how to prepare the floor using a self-leveling mixture under the laminate:

It is necessary to strictly follow the technology of solution preparation, since the liquid mixture quickly loses its strength.

Each section of the floor needs to be re-spilled and pulled together to avoid large depressions, since such a mixture strongly sags due to its fluidity.

Unevenness can be scraped off between sites rule, before the mixture has not dried completely, but you can already walk on it.

When the mixture has sagged and the beacons stick out, they are removeda grinding belt or an abrasive wheel. If a beacon profile is used, it is pulled out, and the empty space is poured with a mixture and subtly tightened.

You can also use a dry screed. The technology of its application is the same, but it is much more difficult to do this. This is because the dry floor screed is thick enough and it is harder to pull it together. In this case, it is best not to use beacons, but a beacon profile. Stir a dry screed with a mixer. It should be well rammed, especially at the joints of the plots. A number of specialists recommend to walk around the screed. If the screed is poorly compacted, cracks may appear at the joints of the plots. Back to contents</a>

Aligning a wooden floor for a laminate

The scheme of fixing the log. The main requirement when laying a laminate on a wooden floor is the rigidity of the base. Since the tree is capable of bending, the laminate will also bend over time, the locks will loosen. As a result, joints and creaks are formed. Thus, the foundation must be strong. In order to obtain such an effect, it is necessary to lay logs as often as possible and lay plywood on them, rather than chipboard. The first step is to check the floor. If it does not sag and does not creak, then its evenness is investigated. If a slight unevenness is detected on the surface, a plywood is mounted and fixed with screws. With significant unevenness, the floor is completely disassembled and re-made. The same applies to surface deflections. The technology of preparing a wooden floor is as follows:

The boards are sorted out, are exposed horizontallylags. For this purpose, the markings on the corners are repulsed by the level. Then they are connected by lines at the required height. Lags are nailed to the walls along the perimeter, and the remaining lags are set under the string.

In order to achieve sufficient rigidity, logs (50x50) are mounted every 50 cm. Also, supports are installed. The boards must be at least 40 mm thick.

After a flat board, they are screwed onto self-tapping screws.

When the lag though installed with the necessaryfrequency, but the floor still bends, which means that the boards are thin. To fix the situation, plywood is paved (from 20 mm thick) to the floor and fixed with screws. Thus, the preparation of the floor for laying the laminate is to eliminate all distortions on the surface.
