Where to Buy
Product overview

SL-200 is an ultra-fluid, self-smoothing underlayment designed for the preparation of finished floor coverings. This innovative product can be installed at 1/8" using a gauge rake and smoothing tool, providing a smoother surface and increasing production efficiency compared to multi-coat patching methods. SL-200 can also be used as a self-leveling underlayment up to 1" when a flat or level subfloor is required. Its breakthrough formulation allows for easy installation by a single person, thanks to its long open time and superior flow rate.
