Description
Bostik SL-175 is a premium, cement-based, self-leveling underlayment designed to create a smooth, flat, or level surface before installing floor coverings. Its long working time, low shrinkage, and superior leveling properties make it the ideal choice for demanding applications on, above, or below grade.
SL-175 can also serve as a durable wear layer when a natural concrete look is desired. Topical stains, dyes, and surface treatments further expand the decorative possibilities.
