CustomTech TechLevel-WSF Self-Leveling Underlayment - 50 lbs

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 ceramic and natural stone tile, wood, carpet, and other resilient floor coverings.

Formulated with Controlled Cure Technology™, TechLevel-WSF SLU helps eliminate installation problems such as slow drying, bond failure, crumbling, and staining of resilient flooring caused by the free moisture found in traditional underlayment.

Features:

  • 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

Benefits of Product in the Installation:

  • No lath required for wood frame and OSB subloors
  • No shot blasting required on acceptable surfaces
  • Can be applied from 1/4" to 1.5" thick in a single pour
