TechLevel-WSF SLU is a high-flow, fiber-reinforced, calcium aluminate cement-based, self-leveling underlayment that eliminates the need for reinforcing battens on plywood and OSB in interior wood-framed subfloors. It produces a smooth, level substrate ready for the installation of most flooring materials. Formulated using controlled-cure technology, TechLevel-WSF SLU helps eliminate installation problems caused by free moisture found in traditional underlayments.

No battens required for plywood and OSB subfloors

High strength for nominal pours from 1/4" to 1-1/2"

Low-prep formula; Simply sweep, prime, and pour; no sanding required on acceptable surfaces.

Compatible with most radiant heating systems.
