Henry 544 FloorFree Self-Leveling Underlayment, 40 lb.

Henry 544 FloorFree is a Portland cement-based, self-leveling underlayment formulated to quickly level and smooth interior concrete, masonry, terrazzo, and wood substrates before installing ceramic tile, stone, vinyl or other floor coverings. Its fluid consistency flows into low spots and featheredges, creating a flat, uniform surface without trowel marks. Walk-on ready in as little as 4 hours and tile-ready in 6–8 hours, this 40 lb. bag covers up to 40 sq ft. at 1/8″ thickness—ideal for fast-track residential and light commercial projects.

For best adhesion, prime porous substrates before application. Simply mix with clean water, pour, spread with a gauge rake or trowel, and let FloorFree do the rest.
