PROBLEM TO BE SOLVED: To provide a method for adjusting the moisture of wood flooring, by which it is possible to maintain a moisture content within a specified range over a long period of time and control the generation of a dimensional change, a warpage or the like due to expansion/contraction by performing a secondary moisture adjustment of the initial moisture content without keeping the flooring in a moisture adjusting chamber for a long period of time. SOLUTION: This method for adjusting the moisture of the wood flooring 1 keeps the moisture content of the flooring 1 after moisture penetration within the range of 5 to 13% by secondarily depositing a wetting agent on the surface of the wood flooring 1 and thereby effecting the moisture penetration way deep inside the wood flooring 1. The wetting agent 2 is, for example, composed mainly of a sulfonic acid anionic surfactant. In addition, the wetting agent 2 is preferably deposited onto the wood flooring 1 by supplying the agent 2 to a pair of an upper and a lower sponge roller 3A and 3B and passing said flooring 1 between the rollers 3A and 3B.
