What Customers Are Saying

The product received mixed reviews. Many found it easy to use with a smooth consistency for simple application, and it dried quickly to create a durable, hard surface suitable for patching concrete. However, a significant number reported issues with the patch not fully hardening or curing, remaining soft, sticky, or gummy, and even cracking or shrinking over time. The consensus is that the product can work well for certain applications, but may not be reliable for all concrete repair needs, and customers should carefully follow instructions and be prepared for potential drying and curing issues.

Easy to use!

Would Recommend

Worked great for filling/smoothing vertical edges of a larger patch job. Also great for filling small gaps (where you can't pour concrete or use a mold).

Formulation Changed

I've purchased this product from another vendor before, so I know how it had changed. There appeared to be small, white hair-like substances mixed into the concrete (see attached photo), but it did dry similarly to the old formulation.
