What Customers Are Saying
Customers overwhelmingly praise this floor leveler for effectively filling gaps, patching imperfections, and leveling uneven subfloors. Most find it easy to apply and spread with proper tools like drywall knives, with many noting it feathers and trowels well. However, some report extended drying times in thicker applications and difficulty achieving smooth finishes without sanding. Several mention the cured material is extremely hard to sand. Despite these challenges, most customers consider it effective for subfloor preparation when applied correctly.

Would RecommendThis stuff was a bit like pancake batter. Thick, gritty, and rubbery. Pretty much exactly what you want for filling large voids or leveling two uneven surfaces. But it was basically impossible to feather out thin to cover joints and wasn't very good for staple holes either. Found it near impossible to sand after. If you're laying LVT or LVP on this, it should be fine. But I couldn't get a smooth enough surface for vinyl sheeting.
Super easy to use
Would RecommendSuper easy to spread and dries quickly. A little sanding and surface is ready for flooring of choice.

do not buy
Would Not Recommendthe bucket was busted and no one open it to check it. I will never order from lowes again if you don't have it in stock I will go somewhere else.

Sandy gritty difficult to spread
Would Not RecommendI bought this Flexible Patch for interior and the Platinum patch for exterior. What a difference. HUGE. The Flexible patch has sharp, gritty, course sand and is difficult to spread as well as adhere to the OSB. And it covers about half of what the Platinum does. I will not buy this product again. If you want value - go with the Platinum.

Good product - good price
Would RecommendNice to have a small volume of pre-mixed leveler on small jobs where you don't need to level a large area. An expensive way to go for larger jobs.

Not sure what this is floor but big holes failed
I didn't realize this "remains flexible" and I used it on a 6 inch wide 1/4 inch deep hole. After 6 months a large person stepped on the spot and now it is permanently a hole and the vinyl floor bows every time you step on it. Do not buy if you want a solid leveled floor.

First-time user, was expecting more fluid than the paste I got. Drops of water on the concrete floor and a trowel, and it spread easily like cake icing. .
Useful
Just used it so I don’t know if it’ll hold up long term but was perfect for filling in shallow pitted areas for tiling.

Easy to use with good 6” drywall taping knife
Would RecommendEasy to use/float with 6” drywall taping/joint knife. Hardens and Adheres to Plywood Subfloor really well without cracking. Used to fill in voids left in joints from replacing subfloor in old kitchen and master bath and also where old subfloor met new subfloor on 40x20 addition to house.
