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.

I’d suggest a pour on leveling compound instead

Would Not Recommend

Too flexible, and seemed to be selectively adhesive. Fair amount of chunks across three different containers I bought.

Quick drying!

Would Recommend

This compound is very useful for leveling out some uneven spots due to plywood used for subfloor not being even. When there was carpet previously, it was not a problem, but this helps solve those issues to help prevent cracking of our our lvt. It does dry very quickly, especially if you have a fan going on it. I was able to cover the entire bathroom and laundry room and sitting room that I was using it for with no problems of it adhering to the plywood.

I purchased this with no experience using it. I was told prior that I needed another product that cost triple & alot more work. This was super easy to use and dries fast.

Pulls up as you spread it.

Would Not Recommend

I do drywall and still had difficulty with getting a smooth finish. As you trowel the product it pulls up little bits behind you. It's almost like the product is too thick or not mixed consistently. In hindsight I should have tried kneading the entire pail and then applying it (although the directions say this is not necessary). I had a concrete floor channel cutout for utilities that I leveled with Quick Level RS and surface primer. There were uneven edges that I used this product on top...
