A self-leveling underlayment used to smooth and repair an existing gypsum substrate that is otherwise unsuitable to receive new finish flooring.
Product Capabilities:
ARDEX GS-4 is intended for use as a remedial material for distressed gypsum subfloors that have suffered degradation. It can also be used to smooth over building code-approved structurally sound wood, and over gypsum or wood subfloors that contain hydronic heating tubes or low voltage electrical in-floor heating systems. It can be installed from 1/4” up to virtually any thickness to achieve the desired flatness tolerance. It can be walked on after 3 hours, and floor covering can be installed as soon as the underlayment has dried sufficiently for the floor covering selected. The drying time is a function of temperature, humidity, and the thickness at which the material is applied.
