Acceptable Moisture Levels
Moisture mapping is a process utilized to accurately measure the moisture content of a material or surface.
Moisture levels are classified as either acceptable or unacceptable. Acceptable moisture levels indicate a material is sufficiently dry and not prone to issues resulting from excessive moisture.

**Moisture-Resistant Drywall:**
– Normal moisture content: 5-8%
– Moisture content up to 12% is acceptable
**Water-Resistant Drywall:**
– Normal moisture content: 2-4%
– Moisture content up to 6% is acceptable
**Note:** Exceeding the acceptable moisture levels indicated above can lead to moisture-related issues such as mold, mildew, and structural damage.
