Moisture content can be measured with a moisture meter. Different types of flooring have different acceptable moisture levels. The acceptable moisture reading in a hardwood floor varies depending on the species of wood, the type of hardwood flooring, and the environment in which it is installed. Generally, an acceptable moisture reading for solid hardwood flooring ranges from 6% to 9%. Engineered hardwood flooring, on the other hand, has a wider acceptable moisture range of 4% to 12% due to its multilayer construction.
Engineered hardwood flooring is constructed with layers of plywood or high-density fiberboard (HDF) topped with a thin veneer of real hardwood. Because of this construction, engineered hardwood flooring is less susceptible to moisture fluctuations than solid hardwood flooring. It can withstand higher moisture levels without warping or buckling.
Solid hardwood flooring is made from a single piece of solid hardwood. It is more susceptible to moisture changes than engineered hardwood flooring and can warp or buckle if the moisture content is too high or too low. Solid hardwood flooring requires a more controlled environment with consistent humidity levels to maintain its stability.
Several factors can affect the moisture content of a hardwood floor, including:
