In this method, a plurality of panel-like floor materials are formed from wood plywood, and the floor materials are laid on the floor. The floor material has a moisture-proof treatment on the front and back surfaces.

[0003] In such a conventional flooring material, the wick of the side surface is not subjected to moisture proof treatment, so that moisture absorption (moisture content) of the flooring material changes due to moisture absorption and discharge from the cleaver, The floor material had a small expansion and contraction ratio and did not cause warping or pushing up after being laid on the floor. However, recently, it has become difficult to use such plywood due to restrictions on tree cutting, and as an alternative to plywood, a chipboard formed by solidifying multiple pieces of wood chips and a piece of wood once unraveled There is a tendency to use wood fiber boards or the like which are formed into a pulp by being woven.

[0004] As shown in Table 1, such a wood fiber board and a wood chipboard have a larger expansion and contraction ratio due to moisture absorption and discharge than plywood. When laid on the floor, there is a problem that warping or pushing up occurs due to expansion and contraction. Therefore, it has been considered that the wick at the side of the flooring made of a wood fiber board or a wood chipboard is subjected to a moisture-proof treatment.
