Wood Moisture Content

Wood moisture content (MC) is a crucial factor influencing the treatment and performance of wood. MC is expressed as a percentage of the weight of water present in the wood relative to the weight of the dry wood. Understanding MC is essential for professionals working with wood to ensure proper preservation, protection, and longevity.

What is the Preferred Moisture Content for Treating Wood?

The preferred MC for treating wood varies depending on the treatment method and the intended use of the wood. Here are general guidelines for different treatment types:

• Preservative Treatment: Typically requires MC between 12% and 18%.
• Fire Retardant Treatment: MC should be below 15% for optimal penetration of the treatment solution.
• Kiln Drying for Dimensional Stability: MC is reduced to 6-8% to prevent warping, splitting, and other dimensional changes.

It’s important to note that these guidelines may vary slightly based on the specific treatment being used and the species of wood. Consulting with a qualified professional is recommended for specific recommendations.
