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.

Not for fine cracks-probaby ok on larger ones

Would Not Recommend

Used on pool deck cracks, putty knife smoothe, using wet knife as suggested. Difficult to hide even after palm-sanding and paint. May be ok on larger projects.

This is not a smooth filler

Would Recommend

The application was easy, but it was extremely grainy and didn't leave a smooth surface.
