Key points about installing laminate flooring.
Allow the laminate flooring to lie in the room for two days before laying. This is necessary so that it adapts to the microclimate of the room and equalizes its humidity with the humidity of the room. This rule is especially important during the winter months when it is picked up from unheated storage areas.
The optimal temperature for laying the floor. is 18-22 degrees and humidity 40-65%.
The laminate flooring is laid on the principle of a floating floor. That is, it is not fastened to the substrate and is not spread by the walls of the room. Compensation gaps must be left between the walls of the room and its edges, approximately 8-12 mm. These gaps are necessary to compensate for the thermal expansion of the laminate with changes in temperature and humidity in the room. These gaps can easily be bridged with small scraps from the laminate. Its thickness is just right for this.
It is better to lay the panels so that the joints are perpendicular to the window in the room. In this position the joints will not be illuminated by daylight.
Before you start the installation you need to calculate the width of the last row of laminate. It must not be less than 50 mm. If it is less, the first row has to be trimmed accordingly.
Width of the last row of panels.
If you install a laminate floor that is 7-10mm thick in a room that is more than 8m long and 6m wide it is advisable to leave extra expansion joints 2 to 3cm wide. If you are laying a laminate floor with a thickness of 10mm you can lay the floor without expansion joints on a maximum 10x12m surface.
Expansion joints in a room with a large surface area.
Expansion joints are closed with special strips. The panels must not be screwed or glued in place. These planks are fastened to the subfloor.

Laying methods for laminate flooring.
If the laminate flooring is chamfered on its edges then it is better to lay it following the pattern. This can be offset by half or 1/3.
- laying using the cut off piece. In this case the leftover cut-off board from the first row is laid at the beginning of the second row, and then the whole pieces are laid. If the leftover length is less than 30cm then the row has to be rearranged so that the last panel in the row has to be at least 30cm long. To do this, you will need to trim the first panel by the required number of centimeters and then you will need to make sure that the remaining length is not less than 30cm.
- Laying diagonally at a 45 degree angle to the wall.
Features of diagonal laying of laminate flooring
Laminate is loved by modern homeowners and craftsmen for its versatility. The material is easy to install and easy to maintain. It is not afraid of the slightest scratch, like varnish on the parquet, does not fade like linoleum, does not squeak like a boardwalk. On sale you can find laminate with a top layer, surprisingly accurately imitating wood or stone. In short, it is a good ratio of quality to the cost of acquisition.
Are there any disadvantages to installing laminate flooring diagonally? Yes, defects can be removed in this case, too. First of all it will increase the consumption of building material and complication of calculations before laying. The work will be more laborious, requiring attention and diligence. The amount of construction waste will increase if the room is small.
Attention ! Reject the diagonal laying of the laminate and in the case where the room is often high humidity, such as in the dining room. Excess moisture can make the laminate flooring swell, the surface of the floor in this case loses its perfect smoothness, and in diagonal laying the irregularities will be even more noticeable.
Before you lay a laminate floor you should pre-plan the layout, following some important rules.
- The flooring should not have cross joints. Laying should resemble masonry, where the joint rests in the middle of the previous row of panels. This option is the most reliable, but requires a lot of trimming, so most craftsmen shift the seam on the length of the segment that remained after laying the last strip of the previous row, if its length is not less than 30 cm.
- The direction of the panel can be longitudinal, transverse or diagonal. The latter method is the most difficult to implement and requires greater material consumption.
- The minimum thickness of the trim on the wall along the grain line is 5 cm.
- It is recommended to draw by hand a simple plan in scale and sketch the future layout.
- The simplest and most economical scheme is that the cuttings from the last panel of the laid row is laid as the starting element of the next row. The docking of the panels is chaotic.
- Joints are better placed along the flow of light.
Advice! If the width is a small balance, it can be overlapped, stepping back from the wall 1-1.5 cm, which will be covered with a baseboard.
