I bought several tubs of this mixture to patch a big crack in our floor. It worked great! It filled the crack and had enough substance not to droop too badly. I just troweled it in and let it set. I will comment that you need to be careful to clean up any that gets on tile or other surfaces right away, it really bonds later. It shrinks back a little in the larger areas, but you can fill that on a second application and the stuff seems to bond well with the adjacent concrete. You can't get such a good repair just by mixing up a bunch of mortar. The mortar would be much cheaper per unit, but if you only have small amount to fill, you will wind up with a lot of waste. It even filled some really shallow places and bonded well, mortar would have just dried prematurely and flaked up. This hardened nicely.

Purchased to fill a crack in the porch. A portion of the porch is sinking so purchased this to smooth out the crack and try to level for safety. The intent was to sand it smoother so there would be no accidents. Luckily it was easy to fill the crack pretty flush, since this is so strong, it really no way to sand it. It is pretty thick and not at all the consistency of say....dry wall patch. I recommends not to add water, which would make it easier to patch in a neater manner, but it will definitely get the job done.

I used this on the verticle surface of a step to fill a gap where the concrete had fallen away. It has the tedency to sag a little when fresh and takes awhile to set up so had to go back several times with the trowel to re-press it. When it dries it is as hard as steal and indestructible. This will not fall out. Dap certainly makes quality home repair products.

just wanted to say that this tub of cement worked like a charm for some small foundation cracks and around my front porch. It is tacky enough to stick and fill in vertical cracks with no need to be an expert. I used the entire contents to fill in my entire front porch and it looks like it did the job.

I'll probably order this again if I see more cracks.. And it really dries quickly and it seems very hard to the touch. Hopefully it will last..

Love this stuff. However, a quart is too small. It comes in a one gallon size if you can find it.
