CustomTech TechLevel WSF 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 helps eliminate installation problems caused by the free moisture found in traditional underlayment.
