### Wood Moisture Content
Wood moisture content (MC) refers to the amount of water present within the material, typically expressed as a percentage. It’s crucial for various aspects of woodworking, including painting and structural integrity. Excessive or deficient moisture can lead to problems.
### Optimal Moisture Content for Painting
Before painting, it’s essential to ensure that the wood has reached an optimal moisture content to achieve a successful finish. Too high MC can result in peeling or cracking paint, while too low MC can cause excessive shrinkage and damage the wood’s integrity.
**Recommended Moisture Content:**
* **Interior:** 6-12%
* **Exterior:** 8-14%
### Measuring Moisture Content
Moisture mapping is a technique used to determine the moisture content of wood, typically using a moisture meter. It’s a non-destructive method that provides a precise reading.
### Importance of Moisture Mapping
* **Ensures optimal painting conditions:** Avoids peeling or cracking paint due to excessive or deficient moisture.
* **Maintains wood integrity:** Prevents shrinkage and structural damage due to moisture imbalances.
* **Improves wood stability:** Regulates moisture content to enhance durability and prevent warping.
