TechLevel™ WSF – Fiber Reinforced Self-Leveling Underlayment for Wood Subfloors

Product ID: TDS320

TechLevel-WSF SLU is a high flow, fiber reinforced calcium aluminate cement based, self-leveling underlayment that eliminates the need for reinforcing lath over plywood and OSB on interior wood framed subfloors. It produces a smooth, level substrate ready for the installation of most floor coverings. Formulated using Controlled Cure Technology™, TechLevel-WSF SLU helps eliminate installation problems caused by the free moisture found in traditional underlayment.

  • No lath required for plywood and OSB subfloors
  • High strength for 1/4″ to 1.5″ nominal pours
  • Low Prep Formula; Just Sweep, Prime & Pour- no sandblasting required on acceptable surfaces
  • Compatible with most radiant heating systems
  • Exceeds TCNA and ASTM requirements for ceramic tile and resilient floor covering installations
  • High flow formula has excellent handling and exceptional flow retention properties
  • Zero flame spread per ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials
