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.

Would not smooth out

Would Not Recommend

Horrible product. Opened the small tub, applied it over a clean plywood subfloor and it would only clump up. It would not smooth out or stick to the plywood. I used a similar product prior and it went on flawlessly. Smoothed right out 1st try. This product is garbage.

Don't buy it!

Would Not Recommend

It's way too thick. Doesn't spread easily. It pulls up from the floor as you try and spread it evenly. Waste of my time and money. One of the worst leveler I ever used.

Does the job

Would Recommend

We used this to level out the second story subfloor and fill in holes, etc. It's easy to work with but takes about 6 hours to dry. Sanding went easy. All around a great product and worth a recommendation.

Takes too long to Dry/Harden.

Would Not Recommend

I patched a 2 inch by 5 inch by 3/4 inch thick missing piece if marble tile on dry plywood indoors. 75 degrees. Even blowing a heater on it. a full day later and it has just barely started crusting on top. Inside still soft. I don't know when its finally going to get hard and dry. Several days it looks like. Then I will finally be able to put a top coat on it to smooth it out like the surrouinding tile. Maybe three days from now??
