SL-250 Light™

SL-250 Light is a specialized, calcium-aluminate-based, interior self-leveling underlayment designed for scenarios where the weight of traditional self-leveling underlayments would exceed the permissible load. This product is ideal for creating flat or level floors without the need for lightweight beads or capping with conventional materials before installing the finished floor covering. SL-250 Light can be applied in thicknesses ranging from 1/4" (0.64 cm) to 2" (5 cm) in a single lift and is ready to receive finished floor coverings in as little as 16 hours.

This underlayment is perfect for both barrel mixing and pumping applications and can withstand normal construction traffic for up to 12 months. It is resistant to mold and mildew, can be installed from 1/4" to 2" neat, and maintains healing and pour merging properties for up to 25 minutes. Additionally, it offers a fast return to service, being walkable in just 2-3 hours. SL-250 Light is compatible with all adhesives approved for concrete, can be feather-edged to meet existing elevations, and contributes points to LEED® Certified Projects.
