Sashco - 16210-12 Slab Concrete Crack Repair Sealant, 10.5 Ounce Cartridge, Gray (Pack of 12)

We were having a hard time finding this product in our town so we ordered here and it came in just as we needed it. It would super durable, easy to use and customers were happy.

Easy installation. Great stability.

I have a driveway above a parking garage, and the concrete is cracked like a spiderweb in places. I use Slab there because it tends to blend well with the concrete and its just easier to use around so many smaller cracks on that part of our slab. Time will tell how well it stands up to the heat and cold. So far I haven't seen it crack the way regular caulk has done after just a few months.

I cannot comment about its longevity because application was about a month or two ago. Application was smooth, and immediate results noticeably improved the concrete's appearance.

This has held up through all 4 seasons on my very old, cracked driveway. It was a lot of work to prepare the cracks, I used a steel brush, pushed a foam rod filler in, then the sealant. In some cracks I had a problem with the foam not staying down, so I just used the sealant. It has a sunken appearance in those areas, but has stayed adhered to the edges of the cracks. My cracks ranged from 1/4" to well over 1' (large ones I used 2 foam rods side by side). I used a LOT more sealant than I thought I needed, but if it will last for years, it will be worth it.

Great concrete caulk for small crack jobs

I'm fixing cracks in my driveway this product works great easy to use and work well and matches the color of the concrete fairly well not as noticeable as some of the other products I'm very happy with this product and would recommend it.

Used this for both vertical and horizontal concrete crack repair. The product is not runny! Stays in place, easy to work with and easy to clean up.
