This is the one
I used a different product last year that was more like a gritty concrete in a tube that did not survive the winter- cracked and fell out. I knew on the first application that this was the real deal- it comes out thick, levels well with a putty knife and stays put, even when filling vertical cracks in my front patio. I used backing for the large crack in my shed concrete pad and this filled in well and looks great. When dry it feels like it will flex and make it thru the seasons.

Good Product But Wasteful
It works, but has an extremely large nozzle that wastes material.

Good price and really works.
I'm using this on some cracking on my pool deck. After following the instructions the repair went very well.

Hard to dispense out of the tube.
Seems to work well, but is ridiculously difficult to dispense.

Dried evenly and looks good
This sealant did the job! It matched nicely and dried evenly.

Bad from the start
I hope I got a bad batch, 2 of the 8 containers burst at the seams and made a horrible mess, after I waited a few days for it to finally dry it still has a really cheap feel and appearance when you walk over it. Not impressed, waiting for the rain and heat to peel it up so I can start over with another brand.
