The ROBERTS First Step Premium 3-in-1 Underlayment, 630 sq. ft. roll is designed for use under floating laminate and engineered wood flooring. This product is meant for use on concrete slabs and wood subfloors that are below, on or above grade. This underlayment creates a pocket of constantly circulating air, which inhibits mold growth. It is effective for sound reduction, moisture protection, comfort and even helps level minor sub-floor corrections.
