Moisture mapping, a critical aspect of hardwood floor installation and maintenance, involves assessing the moisture content of a subfloor to ensure its compatibility with hardwood flooring. This process utilizes specialized equipment to create a “moisture map” that accurately represents the moisture levels across the subfloor’s surface.
Proper moisture content is crucial for the longevity and performance of hardwood floors. Excessive moisture can cause buckling, warping, or even mold growth, while insufficient moisture can lead to shrinkage and cracking. To avoid these issues, it is essential to maintain the subfloor’s moisture level within specific acceptable ranges.
The American National Standards Institute (ANSI) recommends the following acceptable moisture content levels for hardwood floors installed on concrete subfloors:
It is important to note that these guidelines are for general reference only. Always consult with the specific hardwood flooring manufacturer for their recommended moisture levels, as they may vary based on species and construction.
