Not cheap, bud does a good job without too much or surface prep. Sticks well and solidifies with no cracks

When applying you have to use water. I used a spray bottle to thin it out a bit to get into thinner cracks. No colour match so it does show up wherever you apply it.

Did the patch fixing perfect, used an old credit card for spreading with a little bit of water and got perfect finish. Very pleased with quality of finish. Product is still useable if I had more fixing to do. Did not dry up in the container.

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.
