Moisture Mapping A Guide to Wood Moisture Content and Mold Growth

Wood Moisture Content

The moisture content of wood is a key factor in determining its structural integrity and susceptibility to decay. Moisture content is expressed as a percentage of the weight of the wood fiber. It can range from 0% (completely dry) to over 30% (saturated).

The moisture content of wood is influenced by several factors, including:

* The species of wood
* The environment in which it is stored or used
* The thickness of the wood

At What Moisture Content Does Mold Grow on Wood?

Mold is a type of fungus that can grow on wood when the moisture content is above 20%. Mold can cause wood to decay and degrade, eventually leading to structural failure.

The higher the moisture content of the wood, the more likely it is to develop mold. However, even if the moisture content is below 20%, mold can still grow if the wood is exposed to high humidity or condensation.

To prevent mold growth on wood, it is important to keep the moisture content below 20%. This can be done by storing wood in a dry environment, using a dehumidifier, or applying a water-resistant coating.
