Lock the Top

Lock the Top™ Self-Leveling Underlayment (SLU) is an inexpensive, two component and high early strength self-leveling floor underlayment that is easy to use and provides a smooth hard substrate that will accept finishes 16 hours after installation.

Lock the Top™ SLU creates a hard, fast setting, Zero-shrink substrate designed to receive interior & exterior wear surfaces. Lock the Top™- SLU works well with moisture sensitive coatings and adhesives as well as Portland cement-based thin-sets and epoxies.
