## Customer Reviews

### ⭐⭐⭐⭐⭐ No more crack
*by M***N on May 7, 2025*

I recently used this concrete patch to fix some cracks and holes in my driveway, and I’m very impressed with the results. The product was easy to apply, and the instructions were clear, making the whole process quick and straightforward. I simply mixed it with water, applied it to the damaged areas, and smoothed it out with a trowel.Once dried, the patched areas looked seamless with the rest of the concrete. The texture matched my existing surface well, and it even withstood some light foot traffic within a day or two of application. What I really appreciated was how durable the patch is—it’s held up well even through rain and temperature fluctuations, without showing signs of cracking or peeling.The concrete patch has also helped improve the overall look of my driveway. It filled in the gaps perfectly and made the surface look a lot cleaner and more uniform. It’s been a great solution for minor concrete repairs and is something I’d definitely use again for future touch-ups.Overall, I highly recommend this concrete patch for anyone dealing with cracks or holes in concrete. It’s an affordable, easy-to-use solution that delivers long-lasting results.

### ⭐⭐⭐⭐⭐ Repaired concrete statue perfectly!
*by A***N on June 17, 2024*

The media could not be loaded. I bought the single 5.5 ounce tube of pre-mixed concrete patch to “glue” the head that broke off of a concrete duck yard ornament. I followed the directions to kneed the tube and then used it pretty much like glue. I applied the patch to both pieces and held them together for a minute or so, wiped off the excess and tried to smooth it over as best I could. It worked perfectly!!!! It held the duck’s head on without me needing to tape or secure it while it dried. It seems very strong and good. You can see the seam of patch because it’s a gray color and a little more course texture than the smooth white concrete duck I was repairing. But it doesn’t matter because I intended to paint the duck anyway. After painting the duck, it is not possible to tell it was ever broken. I am very happy with this concrete patch. It was very convenient to use, worked well, and reasonably priced.The 5.5 ounce tube is for small jobs. It’s just a little larger and wider than an ordinary tube of toothpaste—so not much patch material inside. But far more than I needed for my repair job. I posted a video and photos to show you the repair process that I used and the “after” result.I am very happy with this pre-mixed concrete patch and recommend it.I write honest reviews to help others make informed purchases because I read reviews myself and appreciate how helpful they can be. I hope that my review helped you.

### ⭐⭐⭐⭐ Works well. Easy to apply, recap .
