It's been over a year and this product has worked wonderfully. Only product I've ever found that works on large & small cracks.

I've tried several things over the years. I end up digging them out of the cracks & redoing. It's been over a year and this product has worked wonderfully. The only issue I had was not enough fine sand. I ended up running around to craft stores to buy uncolored sand to finish.

I needed to repair several hairline cracks in the concrete steps in front of my house. i bought this product with some trepidation because it seemed very difficult to work with. I've had a lot of experience making and fixing things so I thought that I would do better than some of the others who reviewed this product. I was wrong.
I followed the directions exactly. The first problem as that the stuff is so thin that it drips all over. But the main problem is that after a little while (very little while) the mixture of the two components hardens before it is ejected. I worked very quickly without pausing for more than a minute at any point. After I used up about a quarter of the tube, the mixture started leaking out at end of the caulking gun. I wrapped a towel around it and tried to continue. I did a little more but then realized that only the top component was coming out of the tube. By the time I noticed it seemed as though most of the top component was used up but that MOST of the bottom component remained in the tube. At that point I realized that it was useless to go on. I stopped without finishing and threw the remainder of the tube out.
I still have a second tube but am hesitant to use it.
The stuff that I did at the beginning seems OK although the hardened stuff which was not in the crack is impossible to remove. Perhaps, if you don't stop at all, this stuff might work but it's a very difficult material to work with.

Great, but not enough sand
Brad Lundberg•February 27, 2016
This stuff worked great. Had no problems with application, was able to use all the epoxy material. Lost a star because there was not enough sand included, and I was very careful with the sand.
application and packaging is good and product seems strong

Decent product, application and packaging is good and product seems strong. However the color matching to my driveway concrete is off, so it sticks out like a sore thumb. Lets see how long it holds up over the winter.
Five Stars
