### What is Moisture Mapping?
Moisture mapping is a non-destructive testing method used to determine the moisture content of wood. It is a valuable tool for woodworkers, builders, and homeowners alike, as it can help to identify areas of high moisture content that may be at risk of decay or damage.
### Wood Moisture Content
Wood moisture content is the amount of water vapor present in the wood. It is expressed as a percentage of the wood’s oven-dry weight. The moisture content of wood can vary depending on a number of factors, including the species of wood, the environment in which it is stored, and the time of year.
### Preferred Moisture Content for Treating Wood
The preferred moisture content for treating wood is generally between 8% and 12%. This range allows for effective penetration of preservatives while minimizing the risk of warping or cracking.
**Table 1. Preferred Moisture Content for Treating Wood**
| Wood Species | Preferred Moisture Content (%) |
|—|—|
| Softwoods | 8-12 |
| Hardwoods | 10-12 |
### Conclusion
Moisture mapping is a useful tool for identifying areas of high moisture content in wood. This information can be used to prevent decay and damage by allowing for the proper treatment of wood. By maintaining the correct moisture content, the lifespan and performance of wood can be extended.
