What is an acceptable moisture reading in a hardwood floor?
Acceptable moisture content (MC) levels for hardwood gym flooring depend on several factors, including the wood species, flooring system, and environmental conditions.
The National Wood Flooring Association (NWFA) recommends an MC range of:
- 6-9% for interior environments with relative humidity (RH) between 30-50%
- 10-12% for interior environments with RH between 50-70%
Moisture readings are typically taken using a moisture meter. Wood flooring with excessive moisture can lead to buckling, warping, and other damage.
Factors Affecting Moisture Levels
- Wood species: Different wood species have varying moisture absorption capabilities.
- Flooring system: Engineered flooring is less susceptible to moisture absorption than solid hardwood.
- Environmental conditions: Temperature, humidity, and ventilation influence flooring moisture levels.
Consequences of Excessive Moisture
- Buckling
- Warping
- Cupping
- Mold and mildew growth
Tips for Maintaining Acceptable Moisture Levels
- Use a dehumidifier in the gym to control humidity.
- Ensure adequate ventilation during and after exercise sessions.
- Avoid using wet cleaning methods on wood flooring.
- Conduct regular moisture readings to monitor moisture levels.
By understanding acceptable moisture readings and taking proactive measures, you can maintain the integrity and longevity of your gym flooring.
