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.

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

Benefits:

  • A blend of high strength gypsum and Portland cements
  • Repairs existing gypsum and wood substrates above grade prior to the installation of new floor covering
  • Hardens and dries faster than other gypsum products
  • Needs no special curing
  • Easy to mix and apply
  • Install from 1/4” up to virtually any thickness, can be tapered to 1/16”
  • Recommended for use over structurally sound plywood, OSB, and strip wood flooring
  • Install floor covering in 2-3 days
  • Suitable for use with indoor hydronic and electric radiant heating systems
  • Use for interior floors only
