Installing luxury vinyl or laminate over concrete is a standard practice, but it requires thorough preparation. The slab must be structurally sound, dry, and flat. Even if the concrete looks dry, it can still harbor significant moisture vapor. Before installation, perform moisture testing as required by the manufacturer to ensure levels are within the product's limits. Excessive moisture can cause adhesives to fail, lead to mold growth, or damage the core of laminate flooring. If moisture levels are high, a proper moisture mitigation system or a vapor retarder is essential. Additionally, the concrete must be clean, free of oils, paint, or chemical contaminants, and ground or patched to meet the manufacturer's flatness tolerance. For glue-down vinyl, the surface must be perfectly smooth, as any imperfection will show through. For floating floors, ensure the slab is level to prevent joint failure. By investing time in proper subfloor testing and preparation, you ensure that your flooring will be protected from the common pitfalls associated with concrete slabs, resulting in a stable and high-performing floor.
