This is necessary to laminate and temperature adopted the moisture level facilities that directly affect its dimensions. Storage lasts until the moment of installation. In this case the laminate should be in the package, and be more than 1 m from the wall. Manufacturers recommend that adhere to the following mode: the temperature of not less than 18 ° C, humidity 75%.

Preparation uneven grounds

To ensure the strength and durability of theirproduction of flooring manufacturers can only provided a qualitatively prepared basis. This applies to all of flooring and, in particular, a laminate. Otherwise, the laminate can crack, swell, start to make noise when walking, and eventually burst. To avoid this, you need to prepare a good foundation.

Important! Differential uneven floors may be 2 mm to 2 meters high. In this case the laminate will be long. If irregularities will be greater, depressions, cracks, pits, nodules, within a few months laminate locks can become loose and then a sheet of cracked.

Conclusion: the uneven floor will have to dub.

How to align the wooden floor

If the laminate is laid on the old wooden floor, then you need to check it for the following defects:

  • failures of the floorboards;
  • creak;
  • cracks and crevices;
  • irregularities.

To eliminate failures have wooden floorit is partially disassembled. First to parse sub-floor if the failures are still present, then remove and draft floor, anchoring and leveling lags. You can simply fix the subfloor to the joists with screws, but in this case the risk to get a little skewed. Creaking wooden floor elements are fixed with screws. Cracks and fissures shpaklyuem.

How to align the wooden floor Scratching

Scratching the wooden floor

To lay the laminate of these actions can beenough, so we eliminate drops and bumps. One option is to align the wooden floor scraping. It can be done manually, although it is hard, and you can use the scraping machine and carefully sanded surface.

Using self-leveling Mixtures for floor leveling

Fill it with a mixture of self-leveling wooden floor

Another way to align the wooden floor - itpour the self-leveling screed of the mixture. The dry mixture is diluted in water and applied in a thin layer of 10 to 25 mm over the entire surface. This will provide enough flat surface so that the laminate has not warped or cracked.

You can perform a so-called dry alignment: lay on the floor surface sheets of plywood or drywall. For this purpose, plates with a thickness of 1.5 to 2 cm. But experts recommend this method to use when the topcoat is carpet or linoleum. In the case of laying laminate flooring screed perform better.

A method of leveling concrete floor

If the laminate is laid on the concrete floor should be checked for the following defects:

  • cracks and crevices;
  • irregularities.

In contrast to the wooden floor of the concrete base preparation is much easier.

Fill it with a mixture of self-leveling on uneven floor

Fill the self-leveling mixture

The most optimal option is to tie fromconcrete or self-leveling mixture. Screed concrete will require additional efforts: have to wave a shovel and work with the concrete mixer. To fill the self-leveling mixture only need a mixture of water and container. This greatly simplifies the task.

To level concrete floor is also usedsheets of plywood, particle board or drywall. This method is easier and less labor costs. But do not forget, for laying laminate appropriately perform screed, as it is it will provide enough solid and level foundation.

Important! Laminate should be laid on a dry surface. If there is high humidity of wood or concrete floor, you need to spend their complete waterproofing. Then let it dry screed, only then to lay laminate.

Passive noise isolation substrate for laminate

To do substrate noise insulation made of polyethylene foam

The substrate made of cork under the laminate

The plug can be used as a substrate

To improve the noise insulation properties, strengthand durability of laminate flooring to be installed under it support. This may be cork or foamed polyethylene. The substrate must be fixed on the perimeter and the diagonals, so as not slid. On top of the substrate will provide a soft surface for most of the laminate and helps smooth out minor irregularities floor.

How to lay laminate

Leave a space between the wall and the sheet laminate

Reserve 1 cm gap between the wall and laminate

  • between the walls and the laminate must leave a gap of 1 cm for a possible expansion of the laminate due to seasonal changes, temperature and moisture level;
  • the board of the next row to be installed with a shift with respect to the previous series, the shift should be to half board;
  • in the case of pipes or other utilities, must be left between them and the laminate gap of 1 cm;
  • laying laminate adhesive must be allowed to dry completely.
