Wood Moisture Content and Moisture Mapping

Introduction

Moisture mapping is commonly used in the flooring industry to identify areas of high moisture within a subfloor. Moisture Mapping provides the geographical and numerical distribution of quantitative moisture within a specific area. This can be done by utilizing a variety of tools and techniques, including moisture meters and thermal imaging cameras. By understanding the moisture content of a subfloor, it is possible to determine if the subfloor is suitable for the installation of a new floor.

Understanding Wood Moisture Content

The moisture content of wood is the amount of water contained within the wood fibers. The moisture content of wood can be expressed as a percentage, and it is typically measured using a moisture meter. The moisture content of wood can vary depending on a number of factors, including the species of wood, the environmental conditions, and the age of the wood.

Preferred Moisture Content for Treating Wood

The preferred moisture content for treating wood is between 12% and 15%. Wood with a moisture content below 12% is too dry, and wood with a moisture content above 15% is too wet. Wood that is too dry is more likely to crack and warp, while wood that is too wet is more likely to rot and decay. To determine the moisture content of wood, a moisture meter can be utilized. It measures the electrical resistance between two prongs that are inserted into the wood. The electrical resistance varies depending on wood’s moisture content. A higher moisture content results in lower electrical resistance. A moisture content value is then displayed on the moisture meter for the user to read.

Moisture mapping is a valuable tool for determining the moisture content of wood. By understanding the moisture content of wood, it is possible to determine if the wood is suitable for the installation of a new floor and subsequently choose the most appropriate treatment for the wood.
