This practice covers the procedure for determining the acceptability of concrete floors for the installation of resilient flooring. It also includes suggestions for ensuring that the constructed concrete floor is acceptable for such installations but does not cover tests for adequacy of the concrete floor to perform structural requirements. A permanent, effective moisture vapor retarder, of the specified thickness and permeance, is required under all on- or below-grade concrete floors. Concrete floors for resilient floorings should be permanently dry, clean, smooth, structurally sound, and free of substances that may prevent adhesive bonding. Surface cracks, grooves, depression, control joints or other non-moving joints, and other irregularities should be filled or smoothed with latex patching or a recommended underlayment compound. The surface of the floor should be cleaned by scraping, brushing, vacuuming, or any other method. All concrete slabs should be tested for moisture regardless of age or grade level while all concrete floors should be tested for pH before installing resilient flooring.
