What is an acceptable moisture reading in a hardwood floor?
Determining the moisture content of a hardwood floor is crucial to ensure its longevity and stability. An acceptable moisture reading, typically measured using a moisture meter, varies depending on the species of wood, the environment, and the desired level of stability.
Generally, hardwood floors are considered to be adequately dry and safe to install when they reach a moisture content that is within 2% to 4% of the equilibrium moisture content (EMC) of the surrounding environment. The EMC is the moisture content at which the wood neither absorbs nor releases moisture from the air.
Factors such as temperature, humidity, and climate can affect the EMC of the environment. In most areas, the EMC typically ranges from 6% to 10%. It is important to note that:
- Readings below 6% may indicate insufficient moisture and could lead to shrinking or cracking of the floor.
- Readings above 10% may indicate excessive moisture, which can cause cupping, buckling, or mold growth.
It is important to consult with a qualified flooring professional to determine the acceptable moisture reading for your specific hardwood floor installation.
