Introduction

Moisture Mapping is a process that is used to identify areas of moisture intrusion in a building. It is an important tool for preventing mold growth and other moisture-related problems.

Acceptable Moisture Levels

The acceptable moisture level for drywall is between 10% and 15%. When the moisture level exceeds 15%, the drywall becomes more susceptible to mold growth.

At What Moisture Level Does Mold Grow in Drywall?

Mold can begin to grow on drywall when the moisture level reaches 20%. The higher the moisture level, the more likely it is that mold will grow.

Preventing Mold Growth

There are a number of things that can be done to prevent mold growth in drywall, including:

– Controlling the humidity in a building
– Properly ventilating attics and crawl spaces
– Repairing any leaks promptly
– Using mold-resistant drywall
