Great crack sealer….
Easy to use. Very liquid. Use foam backer rod for any crack bigger than 1/8”. You will use much less product!

Much more tenacious than I expected.
I finally got around to using this to fill small cracks in my concrete/brick deck. It takes a little while to figure out how not to make a mess but this stuff is really sturdy so far. If I was more ambitious, I'd have found a way to tint it a little to better match the existing. It's not bad but could be better. Standard medium gray but the surrounding concrete changes color slightly from a lot of things and we need to be realistic. I recommend this without reservation.

Nozzle Broken in Shipping
Product worked well and relatively easy to use. However both nozzles on the two containers that I ordered were broken. The nozzles were completely sheared off during shipping. I suspect the weight of the containers rolling around in the box allowed them to slam against each other and the box. There was only some kraft paper in the box. Not sufficient to stop movement. Thus meant I had to use the product with a nozzle taped with Gorilla tape which worked for a while but then just had to pore it out of the containers. Would buy product again but likely only from in store.
