To lay the laminate, the floor must be prepared. It is necessary to remove the old flooring, the floor should be dry, even and clean. If you are going to put a laminate on steam heating or the floor fully consisting of a mineral slab, then as the basis for the laminate you need to put construction foil. For insulation and absorption of the sound of steps, you can use wool -drive cardboard.
To begin with, the first row of laminate without the use of glue is laid on the wall, it is necessary to check whether it adjacent to the wall and is it exactly whether it lies. If everything is in order, you can continue laying using glue. The joints of the panels of the row in relation to the previous ones should shift about 30 centimeters. Panels must be interconnected by glue.
Having put the first few rows, let the glue dry out. These ranks will be a strong basis for further laying.
You can give a load on a laid laminate only after the glue is completely dried up.
