Acceptable Moisture Levels in Drywall
Moisture is a natural part of the environment, and drywall can absorb moisture from the air. However, excessive moisture can damage drywall and create an environment conducive to mold growth.
The acceptable moisture levels in drywall are between 5% and 15%. When the moisture content exceeds 15%, the drywall becomes vulnerable to mold growth. Mold can damage drywall and cause health problems for occupants.
At What Moisture Level Does Mold Grow in Drywall?
Mold can begin to grow in drywall when the moisture content exceeds 15%. The optimal moisture level for mold growth is between 60% and 80%. However, mold can also grow in drywall with lower moisture content if other factors are present, such as poor ventilation or a food source for mold.
To prevent mold growth in drywall, it is essential to keep the moisture content below 15%. This can be achieved by:
- Controlling the humidity in the home
- Ventilating bathrooms and kitchens
- Fixing leaks promptly
- Using a moisture meter to monitor the moisture content in drywall
If mold does grow in drywall, it is important to remove it promptly. Mold can be removed by cleaning the affected area with a bleach solution or by replacing the damaged drywall.
