Nice product, I had some cracks to fill on my driveway and this did it nicely. The self leveling feature helped make the job a lot easier and look more professional. Would I use it again? For filling cracks that are horizontal, absolutely. I'm not sure how it would work on a vertical application though.

I first used this product three years ago to patch cracks in my aggregate patio, sidewalk and driveway. It applies very easily (like a thin gel or a very thick liquid) and cures quickly to a rubber-like seal. I then painted over to more closely match the color of the surrounding surface. The elastomeric nature of the product is very important because the concrete will expand/contract over time and a traditional concrete patch will just crack again. It's very important to get a waterproof seal or water will penetrate and freeze during winter and make the crack worse. Or, the water will swell the underlying soil and cause movement and more cracking. As long as the seal holds, it is watertight. Of the three crack locations I patched 3 years ago, I just inspected and reapplied with this product again as needed. One large area of patching was still completely sealed (my patio), one long crack needed to have a few updates(my driveway), and one crack had completely opened up and ruined the seal (walkway). The crack that opened up was on a 90 degree turn in which the installer should have placed an expansion joint. The crack in the driveway had been exposed to vehicle traffic and occasional snow shoveling. So I don't fault the DAP product for not holding up 100%. If you've fixed the original cause of the crack and cleaned the surface before application, I can vouch for the product lasting at least 3 years in a northwest climate. As a note, I'd recommend being very diligent about checking the expiration date on these products and storing them within proper temperature ranges. I believe it's chemically cured and thus will fail to harden if too old or spoiled by temp extremes.

I got this stuff late in the season and barely made the required temps for max adhesion and leveling. Still worked pretty good.
Took some extra time to cure properly. That's on me. Once it cured it did the job as advertised. I'll put a finish coat and touch-up
in the spring, but so far I am very pleased with this product. Would buy it, would recommend it. Color is lighter than I had envisioned, but am sure over time that will not be noticeable. Fill those cracks with confidence.
