## Moisture Mapping: A Comprehensive Guide Moisture Mapping provides a detailed analysis of moisture distribution within a structure. It involves using specialized equipment to measure and create a visual representation of moisture levels, aiding in identifying potential moisture problems and guiding remediation efforts. ## Wood Moisture Content and Painting Before painting wood, understanding its moisture content is crucial, as it directly affects the paint's adhesion and durability. ## What Should the Moisture Content of Wood Be Before Painting? The optimal moisture content for wood before painting varies depending on the type of wood and environmental conditions. Generally, the following guidelines are recommended: **Interior Wood:** * Softwoods: 8-12% * Hardwoods: 6-9% **Exterior Wood:** * Softwoods: 12-15% (up to 18% in humid climates) * Hardwoods: 9-12% (up to 15% in humid climates) **Measuring Wood Moisture Content** Accurately measuring wood moisture content is essential to determine if it's suitable for painting. This can be done using a moisture meter, which measures electrical resistance or capacitance within the wood to provide a moisture reading. **Consequences of Excessive or Insufficient Moisture** **Excessive Moisture:** * Paint may blister, peel, or crack * Rot and decay may occur **Insufficient Moisture:** * Wood may shrink, causing paint to crack * Absorption of paint may be poor By adhering to these guidelines and understanding the importance of moisture content, you can ensure optimal paint performance and protect your wood surfaces from damage.
