A self-leveling underlayment used to smooth and repair an existing gypsum substrate that is otherwise unsuitable to receive new finish flooring. Use this product to install our metallic epoxy system!


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.


Coverage:
22 sq. ft. per bag at 1/4"
11 sq. ft. per bag at 1/2"
