Subfloor preparation is critical to the longevity of luxury vinyl (LVP/LVT) installations. The subfloor must meet strict flatness criteria to prevent joint failure or premature locking mechanism stress, which often manifests as gapping or buckling. Guidelines require the surface to be free of debris, waxes, or oils. If the substrate is concrete, it must be cured and free of excessive moisture emissions. For uneven surfaces, professional-grade self-leveling underlayments or cement-based patch compounds are used to achieve the necessary tolerance. Always verify local and manufacturer-specific requirements, as improper preparation can void warranties and cause visible telegraphing of imperfections through the vinyl surface.

What are the standard guidelines for floor leveling before installing luxury vinyl?
For luxury vinyl, the subfloor must be clean, dry, flat, and structurally sound. Industry standards typically require the subfloor to be flat within 3/16 inch over a 10-foot radius. Any deviations, cracks, or protrusions must be addressed using leveling compounds or sanding.
