What Customers Are Saying

Customers overwhelmingly praise this floor leveler for effectively filling gaps, voids, and uneven subfloor areas, with most noting it bonds securely to old surfaces and works well on concrete, plywood, and tile. Reviewers consistently describe it as easy to apply with standard tools like putty knives, feathering smoothly and remaining workable long enough to achieve level finishes. Drying times vary significantly by thickness—thin applications dry within 24 hours, while thicker layers take two to four days or longer, sometimes remaining soft in humid conditions. Some find it extremely difficult to sand after curing, requiring chisels or scrapers for high spots. Despite these drawbacks, most customers consider it reliable and effective for subfloor preparation.

Dried strong after 24 hours.

Would Recommend

Didn't really like the texture, I was expecting something a little thinner and self-leveling.

good but not per directions

Would Recommend

This product works well but only witg very thin applications. The directions recommend 1/4" max but it's more like 1/8" max or even less or it will not dry.

Came halfway dried out and does not spread!!

Would Not Recommend

Do not recommend. This leveler is very thick and is hard to spread. Mine was bought and opened the same day, halfway dry and crumbling on the top layer. Recommend Henry 345 instead.
