What are the acceptable moisture content levels for wooden flooring?
Moisture plays a significant role in how well your floors perform and how long they last. One crucial factor to consider then, is moisture content. Understanding the impact of moisture on your flooring can help you make informed decisions. By keeping these moisture guidelines in mind, you can prevent common issues like warping or cracking and enjoy beautiful, durable floors.
Why moisture content matters?
Wood is a natural material that naturally absorbs and releases moisture from the air. If the moisture levels in the wood aren’t balanced, it can cause issues like warping, swelling, or cracking after the installation. It is essential for the warranty of the installation that the moisture content in the flooring planks is checked prior to the install.
Measuring moisture content
To check the moisture content of wooden floors, professionals use a tool called a moisture meter. This device measures the amount of moisture in the wood, ensuring it falls within the ideal range before and after installation.
Different timbers and construction materials have different conduction, used to register moisture levels. There are many moisture readers, however it is important that the tool(s) used for measuring are able to read correctly in various timbers - oak, beech, walnut, pine, spruce, etc. or concrete, plaster etc. Room and air-humidity should be noted as well.
What are ideal moisture levels for wooden floors?
Acceptable moisture levels for most timbers is 7% - 12%, where 12% can be an indication of damp / leak source in an existing installation or flooring product, which was not properly addressed or managed. This range helps the wood remain stable once it’s installed, reducing the risk of expansion or contraction.
Acceptable concrete subfloors levels is below 3%. High moisture levels in concrete can lead to a range of issues, including mold growth, floor warping, or adhesive failure.
How to Maintain Proper Moisture Levels
Control Indoor Humidity: Use a humidifier or dehumidifier to maintain consistent indoor humidity levels.
Avoid Excessive Moisture: Be cautious with water spills and avoid installing wooden floors in very wet areas like bathrooms or basements unless proper moisture barriers are used.
Use the Right Cleaning Products: Use cleaning solutions specifically designed for wooden floors. Avoid harsh chemicals or excessive water, which can increase moisture levels or damage the wood.
Ensure Proper Ventilation: Improve ventilation in your home by opening windows and using exhaust fans, especially in high-moisture areas like kitchens and bathrooms. Good airflow helps regulate indoor humidity levels.
By ensuring that concrete subfloors are properly dried and moisture levels are kept below 3%, you create a stable, dry foundation that supports the longevity and durability of your flooring. This proactive approach helps prevent costly repairs and ensures your installation remains in top condition for years to come.
