Properly installed drywall is tolerant to moisture up to a certain point. However, excessive moisture can lead to mold growth, which is a health hazard. Mold spores thrive in enclosed environments with high humidity and moisture levels. It is important to note that drywall is more susceptible to moisture damage than other building materials such as ceramic tile or vinyl flooring.
The moisture tolerance of drywall depends on several factors such as the type of drywall used, the installation method, and the environment in which it is installed.
At what moisture level does mold grow in drywall? As a general rule, mold will grow when the moisture content of drywall exceeds 15%. It is important to maintain a relative humidity (RH) of less than 60% to prevent mold growth.
To prevent moisture damage and mold growth in drywall, consider the following measures:
Understanding the impact of building materials on moisture tolerance is crucial for maintaining the integrity and health of your home. By choosing moisture-tolerant materials, installing them correctly, and controlling moisture levels, you can prevent costly damage and ensure a safe and healthy living environment.
