    SL-200™ is an ultra fluid, self-smoothing underlayment used in preparation of finished floor coverings. SL-200™ can be installed at 1/8" using a gauge rake and smoothing tool. The ultra fluid, single lift application increases production over multi-coat patching methods and leaves a smoother surface. SL-200™ can also be installed as a self-leveling underlayment up to 1" when a flat or level subfloor is desired. This breakthrough formulation can be easily installed by one person, working alone, due to its long open time and superior flow rate.
