Luxury Vinyl Plank (LVP) is a durable product, but it is sensitive to subfloor imperfections due to its flexible nature. If the subfloor has high spots or significant depressions, the locking joints of the LVP may experience stress, leading to clicking or eventual failure. The subfloor must be flat, smooth, and free of any debris, grease, or wax. The industry-accepted standard for flatness is generally 3/16 inch variation over a 10-foot radius. Any deviations must be corrected using self-leveling underlayment or cement-based patch. Moisture testing is also critical, as high moisture levels in concrete subfloors can degrade adhesive or promote mold growth beneath the flooring.

What are the key technical requirements for subfloor preparation for LVP?
Subfloor preparation for LVP requires a surface that is clean, dry, and perfectly flat. Industry standards typically require the subfloor to be level within 3/16 inch over a 10-foot span. Any cracks or low spots must be filled with a high-quality cementitious leveling compound.
