What is a bad moisture reading for wood?

A range of 5 to 12 percent is considered optimal. A reading of up to 17 percent is generally considered moderate moisture and acceptable. Any reading over 17 percent is considered to be an indication of saturation and the need to replace the drywall and to take preventative measures against future moisture buildup.

What does 12.5% moisture content mean in a wall?

It is generally agreed that a moisture content of less than 20% is best.

What is an acceptable moisture reading?

The optimal moisture level for drywall is typically 1% or lower. If the moisture content in drywall is over 1% it is considered compromised and may need replacement.

What is considered a high moisture reading?

The best way to do this is to use an accurate moisture meter. Acceptable wood moisture readings on a meter normally range from 6% to 8% for woodworking. Normal moisture content of wood ranges from 7% to 19%. Be sure to acclimate the wood to desired EMC of the interior environment before you use it.
