Consequences of Installing Floors with High Moisture Content
Understanding Moisture Content
Moisture content in hardwood floors is an important factor that must be taken into account during installation. When the moisture content of a hardwood plank is higher than the acceptable level, it can lead to numerous consequences and potential risks.
What is an Acceptable Moisture Reading in a Hardwood Floor?
Generally, an acceptable moisture reading for hardwood floors should range between 6% to 9%, depending on the geographic location and climate. If the moisture content exceeds this range, the floor may be at risk for issues such as:
Negative Consequences
- Buckling: High moisture causes the planks to expand, resulting in buckling or warping of the floor.
- Cupping: The edges of the planks rise upwards, creating a cupped appearance.
- Crowning: The center of the planks arches upward, causing the edges to curl downward.
- Gaps and Squeaks: As the floor dries, it contracts, resulting in gaps between planks and squeaky sounds when walked upon.
- Mildew and Mold: Excess moisture provides a favorable environment for mildew and mold growth, especially in humid environments.
Avoiding Moisture Issues
To prevent these consequences, it is crucial to ensure that the hardwood floor has been properly acclimated to the installation environment and has an appropriate moisture content before installation. This involves allowing the planks to adjust to the temperature and humidity levels of the room for a period of time before laying them down.
Additionally, a moisture meter should be used to accurately measure the moisture content of the planks and the subfloor. If the moisture content is found to be high, it is advisable to delay installation until the moisture levels have been reduced.
