Drywall is a manufactured panel composed of two paper facers and a gypsum core. It is used for interior wall and ceiling applications. The moisture content of drywall is a key factor in determining its performance and durability.
The normal moisture reading for drywall varies depending on the time of year, storage conditions, and location. However, as a general rule, the moisture content of drywall should not exceed 15%.
Drywall that is too wet or has excessive moisture content may be more susceptible to mold growth, warping, and loss of structural integrity. Excessive moisture in drywall can also provide a more favorable environment for insects and pests.
To prevent moisture-related issues, drywall should be stored in a dry location and protected from the elements. It is also important to allow drywall to acclimate to the environment before installation. This will help to prevent the drywall from absorbing too much moisture and causing problems down the road.
