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.

Do not purchase

Would Not Recommend

I would give this zero stars if I could. everything that is advertised on the container is false. It shrank and cracked after the first application. Then once it got wet, it became soft and fell apart resulting in a damaged fountain water pump. It was cured for 48 hours and this still happened.

I’m band-aiding my house together

Would Recommend

I have a very old home. I used this product to fill some cracks/gaps/holes in my foundation and concrete pad outside my door. It does “sink” a bit as it dries, especially on horizontal surfaces which isn’t an issue if you aren’t sticking glass/ceramic mosaic pieces in it😜
