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.

slow repsonse
Would RecommendThis order took over 2 hours with no response for 2 quart cans of patch. Wasn't ready even when I arrived at store. Too long a time to wait for this order!

Thank you for posting your feedback. DAP Flexible Floor Patch and Leveler is not designed, marketed, or labeled as a a "self-leveling" repair...

Horrible product!
Would Not RecommendDAP should be ashamed to put there name on this product, worst patching material I have ever used. As others have stated dry when opening, mixing with a little water still chunks of rubbery crap. Been using DAP products for many years but will not buy anymore! Pure Garbage!

Excellent product - works best with level floor
Would RecommendI used this to patch joints in underlayment. It worked very well to fill gaps between new and existing underlayment. Use a good putty knife or a small trowel to apply, it could be sanded after drying but after seeing the finished product, that would take a lot of work. This is not self leveling, if you have large gaps or uneven floors consider using a self leveling cement instead of this product.

Great product easy to work with.
Would RecommendGood for sealing cement board and minor floor leveling. Easy to apply. Only wish Lowe’s would have the larger container in store.

Makes my life a little easier
Would RecommendI have used this product since 2016 to patch holes and cracks in concrete and terrazzo floors. Interior temps from ninety to seventy degrees. Exterior concrete carports as sub floors in heat as high as ninety-nine degrees. Florida humidity without rain takes about thirty to forty hours indoor. Exterior with a light plastic sheet covering no more than forty-eight hours. Never found a single case of release from the original substrate and sanding when needed is a breeze.
