What Customers Are Saying

Customers overwhelmingly praise this leveling compound for creating flat, stable subfloors when mixed and applied correctly. Many report successfully transforming uneven concrete into smooth, tile-ready bases, especially on large projects. Reviewers emphasize that precise mixing ratios, proper tools like spike rollers and screeds, and quick application within the working window are critical. Some note inconsistent flow requiring manual spreading, and a few experienced cracking or uneven drying. Several attribute poor results to user error rather than product failure. Overall, most customers consider it highly effective for professional-grade results when instructions are followed carefully.

Worked as advertised.

Would Recommend

I used the primer to prep the surface. The leveling compound did just that--I poured it, and it self-leveled. Easy-peezy.

Worked as intended

Would Recommend

It's self-leveling cement. I used the bonding primer, mixed it in a bucket, and poured it. It worked well, dried quickly, flowed evenly. No complaints.

Once mixed it will do the job.

Would Recommend

Simple, just add water, 1 gal/bag, pour it slow while mixing so it does not get into your lungs. It's quite pricey, around 30 dollars a bag but it's a good product. Once your get started you cannot stop so be dure to plan it all out.

I didn't use it because I didn't read the label close enough to see it was for concrete floors and I needed leveler for wood floors. Then why did I rate it? Well I hope someone as stupid as me reads this and I can save them $39 on buying the wrong thing
