Floating hardwood floors are a popular flooring choice due to their ease of installation, durability, and aesthetic appeal. Unlike traditional hardwood, floating floors don’t require nails or staples to attach to the subfloor, making the installation process quicker and simpler. However, to ensure the best results and longevity, it’s essential to have the right subfloor. Today, we at Mikes Custom Flooring would like to share what you need to know about the ideal subfloor for floating hardwood floors.
Types of Subfloors for Floating Hardwood Floors
Floating hardwood floors can be installed over several subfloor materials. The most suitable options include:
Plywood: Ideal for floating floors, plywood provides a solid, stable, and smooth base.
Concrete: Common in basements, concrete must be level, dry, and free of moisture for successful installation.
OSB (Oriented Strand Board): A cost-effective option similar to plywood, suitable for areas with minimal moisture risk.
Cement Board: Often used when a moisture barrier is necessary, cement board can be a good choice in specific environments.
Smooth & Level Subfloor is Crucial
A smooth, level subfloor is essential for floating hardwood floors. Any unevenness can cause gaps, squeaks, or instability in the flooring over time. To check for levelness, use a long level or straightedge. If the subfloor has high or low spots, these should be corrected by sanding or filling in the uneven areas. For major unevenness, a self-leveling compound may be required to ensure a perfectly flat surface.
Moisture Control
Moisture is a major concern when installing hardwood floors. Excess moisture can cause warping, buckling, or mold growth. For concrete subfloors, it’s vital to conduct a moisture test. This can be done by taping a plastic sheet to the floor and checking for condensation after 24-48 hours. If moisture is present, it must be addressed before installation. Installing a moisture barrier or vapor barrier, especially on concrete or in basements, will protect the hardwood from moisture seeping through the subfloor.
Cleanliness & Preparation
Before installation, the subfloor must be clean and free from debris. Dust, dirt, or other particles can interfere with the adhesive or underlayment, leading to instability. Vacuuming or sweeping ensures the subfloor is ready for the floating hardwood planks, providing a clean surface for a successful installation.
Underlayment Considerations
While not part of the subfloor itself, underlayment is crucial when installing floating hardwood floors. It provides an extra layer of protection, moisture control, cushioning, and soundproofing. Choosing the right underlayment, compatible with both the subfloor and hardwood, will enhance the performance and longevity of your floors.
