Quikrete Concrete Crack Seal Natural 1 Qt

Works great and easy to use!

Very good! This was for a large crack — two of them going across the front of the front porch- it filled it very well and fast in one afternoon- I am waiting for the concrete paint to paint over it- then it will be done! I used two of the liter size bottles

Make sure it's really mixed well. Shaking the bottle hardly mixed it at all for me.I'd suggest mixing it with a spade drill bit through the neck of the bottle. That's how I got good results..It doesn't store well, but will keep longer if you store it in a cool place. Not a hot shed or garage.You definitely need to put backing in wide cracks or it will sink right to the bottom, but even so you will probably need to do several layers to totally fill wide cracks.I was pleasantly surprised how well it set up and filled the cracks in my driveway with a proper application. One bottle went a long way.It's water based, so cleanup and thinning is easy.I'd purchase it again.

THE STUFF IS GREAT. However, AMAZON is not so great with packaging. They pack it loosely in a box. The plastic pourer breaks off, and the content spills in the box.

Ok you know eventually the concrete is going to crack somewhere. I've tried a lot of different methods to fill them in knowing that whatever you use the crack will eventually return. This is the simplest method. Squirt it in or trowel it in and no more nasty hands from mixing concrete

Cracks and gaps? This is what you're looking for. It's self-leveling. Good stuff.

Works ok if you plan to seal the crack annually. Dries out quickly and crack reappears in no time.

Stuff pours out runny, will thicken quickly and sets fast. It will take time to cure and harden. It will self level on bigger cracks and holes. But does not level on the smaller cracks, because of its thickness. So, you will need a spackle to punch the stuff into the smaller cracks to level.
