TechLevel Lite® High Flow Lightweight Self-Leveling Underlayment

Product ID: TDS-457

TechLevel Lite® Self-Leveling Underlayment is a high-quality, flowable hydraulic cement underlayment that helps flatten and level interior floors in preparation for ceramic tile, natural stone, resilient flooring, carpet, wood, and other floor covering installations. This quick-setting underlayment seeks its own level in minutes and can be applied up to 2″ (5 cm) thick in a single pour. It may also be used in residential applications with floor joints up to 24″ o.c.

With CustomLite® Technology, TechLevel Lite weighs 3 lbs. less (1.36 kg) per square foot at 1/2″ (13 mm) thickness than other self-leveling underlayments. A 30 lb. (13.6 kg) bag covers the same area as a 50 lb. (22.6 kg) bag, allowing installers to move, mix, and pour less material while covering more floor area efficiently. TechLevel Lite is also formulated with Controlled Cure Technology®, which helps reduce excess free moisture during curing and minimize installation issues such as bond failure, crumbling, and staining of resilient flooring.

*Leveling requires surveying and setting leveling pins as guides for placing mortar. Refer to ANSI A118.16 & A108.21.
