Dap 18021 Concrete and Mortar Watertight Filler and Sealant - Gray 10.1-oz Cartridge (18096). Sold as 3 Pack

I used this to seal cracks and joints in the foundation of my home (above and below grade) as well as between concrete walkways and the foundation. Very easy to apply and the final color blends in well. Also a better per-tube price than elsewhere. I found it helpful to give the applied bead (as well as my vinyl-gloved finger) a light spray of water first if I needed to smooth out the bead.

Quality product, works good, shipped quickly

I like the ease of application and it seems to dry in a reasonable amount of time. Shrinkage has been an issue, however. It looks great on day one, but on day two I come back to find holes in what was a smooth surface. A second application usually solves that issue, but in some areas I’ve even had to apply a third.

Have used this item many times and does a great job...

Easy to work with, plugged up cracks in basement

I used this to patch bad spots in my concrete driveway. Covers well, turns hard and is gray in color
