SL-150 is a fast setting, self-leveling underlayment that can be used to create a smooth, flat or level surface prior to the installation of floor coverings. Its working time, low shrinkage and superior leveling properties make it the ideal product for demanding applications on, above or below grade.

Barrel Mixing: Pour the blended SL-150 on the floor immediately and disperse with a gauge rake followed by finishing with a smoothing tool. SL-150 will maintain its workability and healing for up to 15 minutes.
NOTE: During application and for first 24 hours prevent excessive air movement but maintain adequate ventilation and protect material from direct sunlight. These variables can cause uneven curing patterns, a false set, or cracking.
