Moisture Mapping Understanding Wood Moisture Content and Mold Growth

Understanding Wood Moisture Content

Wood moisture content (MC) refers to the amount of water held within wood fibers. This content can significantly impact wood’s properties, including its strength, durability, and susceptibility to mold growth. Measuring and controlling wood MC is crucial for maintaining its integrity and preventing damage.

At What Moisture Content Does Mold Grow on Wood?

Mold, a type of fungus, thrives in moist environments. On wood, mold growth can occur when the MC exceeds 20%. This moisture level provides an ideal environment for mold spores to germinate and colonize. Therefore, keeping wood MC below 20% is essential to prevent mold growth and the deterioration it causes.
