ConSandtrate Concrete Crack Filler - Gray - 3 lb. (Single Bottle) for Filling in Concrete Cracks on driveways, walkways and patios.

Worked great will need to see how it last over the winter.

I purchased the brown version of this product to fill in some cement cracks in my backyard that ranged from hairline-type cracks to 1/4 inch. I had previously tried cement but found it difficult to fill in the cracks without it looking messy. This product works nicely for that purpose and this was easy to use. For slightly larger cracks, the nozzle of the plastic squeeze bottle can be placed into/close to the crack to allow the powder/sand to fill the crack. For smaller cracks, also using a small brush to sweep the powder across to fill the crack worked best for me. The product hardens when you spray water on the powder. I used a spray bottle on a mist-type setting to get the powder wet but not soaking wet. Overall, I was happy with the performance of the product, especially how the cracks were filled in and how the powder hardened. The acid test will come with time once we experience freezing temperatures and get into another summer. I was disappointed with the brown version of this product because it was more yellowish/beige than brown. On the Amazon Canada web site, the only 2 colours offered were brown and tan. The Amazon US web site also offered up grey and white and the brown displayed on that web site is nowhere close to the actual colour of the product once hardened. Hopefully, nature will take its course and outside dirt, etc. will darken the colour over time. The other drawback was the cost, which I thought was a tad high for basically 3 lbs of a sand-type mixture. One might be better off buying a bag of polymeric sand and, to get the same effect as this product, putting the sand into a squeeze bottle. Think I might try that next time, especially if this can better match the colour of my concrete.

I had a driveway poured about two years ago. Pretty disappointing that it has cracks already but it is what it is. I tried a few approaches and was wary about this stuff. Finally gave it a try. I have not gone through a winter season with it yet but through spring and summer it has been flawless.

works great for cracks. some areas, don't last with time but I think that is expected.

This concrete crack filler is amazing. It's been almost a year and the cracks I filled last year are still like the day I filled.
