Moisture Barriers for Hardwood Floors
Protecting Hardwood from Moisture
Moisture is one of the most important considerations in hardwood floor installation. Excess moisture moving through a subfloor can contribute to expansion, cupping, buckling, adhesive failure, and other flooring problems.
A properly selected moisture barrier or moisture control system helps protect hardwood by reducing moisture transmission from the surface beneath the floor.
Understanding Moisture Sources
Moisture can reach hardwood flooring from concrete slabs, crawl spaces, basements, plumbing problems, environmental humidity, and other sources within the home.
Identifying where moisture may originate is an important part of determining whether additional protection is required before hardwood installation.
Moisture Protection Options
Depending on the flooring and installation conditions, moisture management may include:
Moisture testing
Vapor retarders
Moisture barrier underlayments
Adhesive moisture systems
Concrete moisture mitigation
Crawl space moisture control
Proper subfloor preparation
Indoor humidity management
The appropriate system depends on the subfloor, flooring construction, installation method, and measured moisture conditions.
Concrete and Hardwood
Concrete can contain and transmit moisture long after it appears dry at the surface. Engineered hardwood installed over concrete therefore requires careful moisture evaluation and an installation system approved for the conditions.
Testing the slab before installation helps determine whether moisture protection or additional corrective measures are necessary.
Preventing Future Problems
A moisture barrier cannot correct an active water leak or serious moisture problem. Plumbing failures, drainage issues, excessive slab moisture, or other underlying conditions should be addressed before hardwood flooring is installed.
Managing moisture before installation is far easier than repairing hardwood after moisture-related damage occurs.
