Moisture mapping is the process of identifying areas of moisture in a building. This can be done using a variety of methods, including infrared cameras, moisture meters, and hygrometers. Moisture mapping is an important part of building maintenance, as it can help to identify and prevent moisture-related problems, such as mold growth.
The acceptable moisture level for drywall is between 0% and 15%. Moisture levels above 15% can promote the growth of mold, which can cause a variety of health problems. Mold can also damage drywall, leading to costly repairs.
Mold can grow in drywall at moisture levels as low as 15%. However, mold growth is most likely to occur at moisture levels above 25%. If you are concerned about mold growth in your home, it is important to keep the moisture level below 15%.
