NXT® LEVEL Flow
UL-certified for fire-resistance! This high-flow cement-based SLU levels substrates, allowing floors in 24 hrs., and meets fire-rated building codes.
NXT® Level Flow is a fire-rated, high-flowing cement-based self-leveling underlayment designed to level interior floor substrates and allow floor covering installations in just 24 hours. Pumpable or pourable, it can be applied from 1/8 inch (3 mm) to 2 inches (51 mm) in a single lift and is walkable in 3 to 4 hours. NXT Level Flow is a UL-certified solution for fire-rated construction, providing up to 2-hour fire resistance in floor-to-ceiling assemblies. With rapid curing, exceptional durability, and direct adhesive compatibility, it serves as a high-performance alternative to traditional gypsum underlayments.
Suitable for use over concrete, gypsum, exterior glue plywood, and other structurally sound substrates, it creates a smooth, level surface for the installation of hardwood, resilient flooring, cork, ceramic tile, natural stone, carpet, and more. This fire-rated floor underlayment offers the high-flow efficiency, speed, and fire-rated protection you need to achieve smooth, reliable, and code-compliant installations.
