Excess moisture is the leading cause of floor failure. Before installation, check the subfloor's moisture content. If the slab is too moist, apply a liquid-applied or sheet-based moisture barrier. Without this step, moisture can cause adhesive failure, cupping in hardwood, or mold growth. Proper subfloor preparation ensures the manufacturer's warranty remains intact and the floor lasts.

What moisture management is needed for floor prep?
Moisture management is critical; always perform calcium chloride or relative humidity tests on concrete subfloors before installation. If moisture levels are high, you must utilize a professional-grade moisture mitigation system or vapor barrier to prevent damage to your new flooring.
