Drywall is a type of building material used in the construction of walls and ceilings. It is made of gypsum plaster sandwiched between two sheets of paper. Drywall is a relatively inexpensive and easy-to-install material, making it a popular choice for both residential and commercial construction. However, drywall can be damaged by moisture, which can lead to mold and mildew growth.

What is a normal moisture reading for drywall?

The normal moisture reading for drywall is between 5% and 12%. This range is considered acceptable by most building codes. However, it is important to note that drywall can still be damaged by moisture even if the moisture reading is within this range. For example, if the drywall is exposed to a prolonged period of high humidity, it can become saturated with moisture and start to deteriorate.

How to measure moisture content in drywall

There are a few different ways to measure the moisture content in drywall. One common method is to use a moisture meter. Moisture meters are relatively inexpensive and easy to use. They can be purchased at most hardware stores.

To use a moisture meter, simply place the probes on the surface of the drywall. The meter will then display the moisture content reading.

Another way to measure the moisture content in drywall is to use a hygrometer. Hygrometers measure the relative humidity of the air. By placing a hygrometer near the drywall, you can get an idea of the moisture level in the area.

If you are concerned about the moisture content in your drywall, it is important to have it inspected by a qualified professional. A professional can determine if the drywall is damaged and needs to be replaced.
