Ratings may include incentivized customer reviews.
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.

Does the job
Would RecommendWe 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 RecommendI 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??

Not easy to work with
Would Not RecommendI found this product difficult to work with. It was very gritty, so not easy to spread evenly. Did I get a bum batch?

Effective but expensive
Would RecommendI had a small 10’ x 12’ room where the decades-old carpet was to be removed and LVP put in. It’s an old house so I was already anticipating issues. It turned out the floor had sagged between the joists in a wavy fashion, with a noticeable dip trending towards the middle. Furthermore, none of the four corners were even level with each other. I opted not to use a cement-based pour leveler because I feel the floor system was not as firm as I’d like, and I didn’t want the cement leveler to event...
Still soft over a day later.
Would Not RecommendI went to a big box store to purchase a gallon of premixed DAP floor patch and leveling. I had to feather in a 16” depth to almost 1/4” thick. After 28 hours it is still soft on the thick side. I need this to dry before I can move forward with a laminate floor tile installation. I put a space heater in this small room which heated to 85 degrees Fahrenheit. Still soft.

Seemingly Old Stock
Would RecommendWhile the product, when fresh and supplied as intended is great, I've purchased several gallons from Lowes and roughly half of them had product that was riddled with dried lumps, making it difficult to evenly spread on the floor. As the product is not available at other stores locally, I have been forced to purchase at the same Lowes store (other stores have not had it in stock when I needed it - and I could not wait for it to be shipped .) Having called the manufacturer, they contend that this ...
