### Wood Moisture Content Wood moisture content refers to the amount of moisture present in wood, expressed as a percentage of its weight when oven-dried. Understanding wood moisture content is crucial for numerous reasons: - **Durability:** High moisture content can weaken wood, making it susceptible to rot and insects. - **Stability:** Moisture fluctuations can cause wood to expand or contract, leading to warping and structural problems. - **Treatment:** Moisture content impacts the effectiveness of wood preservatives and finishes. ### What is the Preferred Moisture Content for Treating Wood? The optimal moisture content for treating wood depends on the treatment method employed: - **Pressure Treatment:** A moisture content between 15-25% is ideal for pressure treatment, as it allows the preservative to penetrate deeply into the wood. - **Non-Pressure Treatment:** Surface treatments, such as paints or stains, perform best when the wood moisture content is between 8-12%. Maintaining the appropriate moisture content is essential to ensure the longevity and effectiveness of wood treatments.
