The scheme of the nuances of correct laminate flooring on the wooden floor.
The job of laying a new flooring will be successful if you follow a strict algorithm.
First you need to inspect the old floor. If there are creaky or rotted, failed boards, they should be replaced or secured so that the coating does not creak. If there is a suspicion that the floor frame is not in perfect condition, you can remove the boards in places to make sure that the lags are strong. Rotten or sagging will have to be replaced. After that, be sure to check the height difference. If it is too large, it is better to remove the coating: the laminate will not last for a long time.
As a result of monitoring, the following picture should turn out:
If all the items are met, laminate can be laid. If not, you will have to start repairing the wooden base.
Note: it is better to remove the rotted or sagging floor anyway. Laminate has a long service life, but an unstable wooden base can cause the locks of the slats to become unusable. Laminate panels themselves may deteriorate. If gaps appear between them, moisture will get into them, which is unavoidable during wet cleaning. This will cause the panels to delaminate.
Monitoring showed that the foundation needs repair. Here are some tips on how to fix minor flaws.
Layout of options for laminate panel layouts.
As a result of all the manipulations, a stable, ideally horizontal base should be obtained (this is checked with a level or level).

If the level indicates that the height difference is in the range of 4-6 mm per square meter, then before laying the laminate flooring will have ottsiklevat. This should be done by dividing the floor into small sections. After processing each carefully check its horizontal and always the quality of the ground surface.When the whole area is processed, check the horizontal position again, but already in the whole room at the same time.
Note: Multiple, but not very large board irregularities can be removed with emery cloth. If there is no looping machine, it will be replaced by an electric plane.
You can level the wooden floor using chipboard or plywood. It is important to remember: the thicker the substrate, the more reliable the final coating will be. In any case, plywood thinner than 15 mm is not suitable. Before laying, sheets are treated with fungicides and anti-mold impregnations (if they are not done in production).
In this case, the order of operation will be as follows.

Sheets are fastened so that the seams between them do not converge in one place.
What should I do if old floors are completely unusable, if the height difference is visible without special appliances? Is it possible to level such a floor?
It is best not to do this: there is no guarantee that rotten boards will hold onto the new surface. In the most extreme case, you can try to lay chipboard, OSB or plywood on the old lags, but experienced builders do not recommend it. It is best to completely remove the old floor, make expanded clay filling, reinforce it with a grid and build a new screed. And already on it to lay plywood.
After all the work, all dust should be carefully removed.
The base is ready, you can proceed directly to the installation of the laminate.
Many manufacturers claim that the substrate under the laminate can hide all the irregularities. This is not true. In addition, the choice of the correct substrate depends on the heat and sound insulation of the floor.
The order of work will be as follows.
The preparatory stage is over. You can lay lamellae.
