Before starting laying the laminate, you need to hold it in a warm room, and then level the entire surface before laying. Before laying, the quality of the upper layer of the base is evaluated, therefore, the horizontal surface of the surface is checked by the construction level. At a distance of about two meters, drops of a couple of millimeters can be allowed. If any deviations were found, then you can apply a screed to the surface of the base, which can itself.
Then, a layer of waterproofing from the polyethylene film is laid on top of the base, which will be perpendicular to the direction of laying the laminate, and the overlap of stripes in the neighborhood should be less than twenty centimeters. So that when laying the laminate there are no shifts of the laid individual stripes, you need to attach them in some places using a special self -adhesive ribbon. Laminate can also be laid directly on the surface of linoleum. For this, at first the evenness and stiffness of the entire surface of the base is checked. In this case, the waterproofing does not fit. As a substrate, you can also use a cork, which is the most environmentally friendly type of material reserve, but more expensive in comparison with other materials.
