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.

Not easy to level

Would Not Recommend

Perhaps if you have a lot of experience this would work. It's quite thick and sandy, difficult to spread and we could not really get it level. Don't attempt to mess with it if it starts drying...it pulled up and would not smooth out!

Floor Leveling Liquid

Would Not Recommend

Did not work for what I was interested in which was to level a floor with a liquid solution before dropping in laminate flooring.

Great Leveling Compound

Would Recommend

After foundation work was done inside my home, i needed to bring the concrete-filled holes back to floor level in order to relay the vinyl tiles. This wass easy to use and worked out well. Easy clean-up, too.

Works good

Would Recommend

Pretty stiff to work with would like it to be a little easier to apply. But not a major problem, and it accomplished exactly what it was supposed to do! I would definitely use it again.

Good, but expensive

Would Recommend

Product worked well, but was too expensive to use for large area coverage.

Will shrink with time

Would Recommend

I thought it was a product that would dry in hours and ready for the floor the same day? No. I had a 1/4 drop on my wood floor to patch where an old furnace used to be. I thought 1 can 32 oz is enough. It shrank and I bought a second can and added to it. That too shrank. A third can. 1 week later, it was slighty below grade. Fourth can! Now it is level! Do not plan to install your floor immediatly. It will shrink and get thinner.

Cannot sand this product even after completely dry. I ruined a brand new belt sander trying to sand this stuff down; company said you could sand it!

Floor level compond

Would Recommend

Great for leveling dips in wood floors before installing new floors.

Tough to use

Would Not Recommend

The material is too thick to work easily into place. Although it takes 6 hours (!!) to cure, it begins to set within moments and becomes even more difficult to work.

DAP Gray Patching Compound Review

Would Recommend

This compound makes it so easy to fill, and level out floors. It does not crack when it dries/hardens, and it is flexible when the there is movement with the wooden floor that I applied it to.

Better than expected

Would Recommend

I wasn't sure how this product would work or turn out. It was very easy to work with. I have always been happy with DAP products. This crack filler did the job that I needed it to. I did need to sand it afterwards and that didn't work out as well as I had hoped. Next time I will be more careful at making sure that I don't have overspill and that I am as level as I can be applying it. Good product!

Works very well

Would Recommend

This product worked very well for my problem. I had the edge of a floor ducked that was raised and in the way of laying my floating floors. I used this to fill the difference and feather it out. It’s supper easy to use and goes on like a thicker drywall mud. It feels very sold once set and I have no concerns about it holding up.
