Prevention is Key to Moisture Control

What is an acceptable moisture reading in a hardwood floor?

A hardwood floor’s acceptable moisture reading varies depending on its species, thickness, and installation method. It is recommended to consult a professional for accurate readings to ensure the longevity and performance of your hardwood floor. However, a general range is provided in this article for guidance purposes.

Moisture Content in Hardwood Flooring

Wood is a hygroscopic material that absorbs and releases moisture from the air. Hardwood flooring should maintain an appropriate moisture balance to prevent warping, buckling, or cracking.

The National Wood Flooring Association (NWFA) recommends a moisture content of:

• 6-9% for solid hardwood floors installed above grade
• 9-11% for solid hardwood floors installed below grade
• 10-12% for engineered hardwood floors

It is essential to monitor the moisture content of your hardwood floor regularly, especially during seasonal changes when humidity levels fluctuate. Using a moisture meter is a simple and effective way to measure moisture readings.

Consequences of Excessive Moisture

Exceeding the recommended moisture content levels can lead to various problems, including:

• Warped or buckled planks
• Cupping or crowning of planks
• Cracking or splitting of planks
• Mold or mildew growth
• Reduced durability and lifespan

Prevention Measures

Prevention is crucial in maintaining the health and longevity of your hardwood floor. Here are some steps you can take to control moisture levels:

• Maintain a consistent indoor humidity level between 30-50% using a humidifier or dehumidifier.
• Properly ventilate your home by opening windows and running exhaust fans in moisture-prone areas.
• Avoid placing rugs directly on hardwood floors, as they can trap moisture.
• Immediately clean up any spills or leaks on the floor.
• Use a moisture barrier or underlayment beneath hardwood floors to minimize moisture absorption.
• Install a vapor barrier below hardwood floors installed below grade to prevent moisture from the ground.

By following these preventive measures, you can effectively control moisture levels and ensure the beauty and longevity of your hardwood floor.
