DAP 7079860500 Concrete Crack Filler, Gray

Awesome job filling the cracks in my driveway. Easy to use, just fill the crack and sprinkle water. Smooth look, more of a concrete fix than a "caulking" fix like some other products.

So far, so good. It works fine, I don't know how it will hold up long term. We shall see. Expensive for the amount. But good stuff. DAP always delivers.

This is a solid product, but I agree with some of the points made by others. It is a little grainy and it does not do fine cracks well.It does dry to be very durable and it blends in with existing concrete well.For those that are looking for finer powder to fill in small cracks and imperfections, consider using Rock-tite. It works well, but is whiter in color.I have a feeling that Rock-tite and this product could be mixed, but I haven't tried that yet .

The usage is straightforward. Poke a hole on the spout just big enough for the sand-like filler material to go through, pour on the crack, then mist with some water and let dry. It’s like a magic cement in your pocket (the package itself is actually smaller like fits on the palm of your (big) hand. I used this for prepping our garage and I was able to cover 70% of all the holes in our 3 car garage in about an hour. What I don’t like is that the texture of the filler is not fine enough that I got some hairline cracks in our garage that it couldn’t fill (I’m planning on getting a liquid-based concrete repair kit that’s similarly priced that can fix those hairline cracks). Another thing is that any extra filler that does not fall into the crack holes balls up to bigger grains when misted and scraped. This unfortunately adds another step (buffing out the balled up grains from the garage floor, and cleaning thereafter). Had I known it beforehand, I would have gotten the liquid-based competitor to save a step. But I guess one positive from it is that it dries fairly quickly (a few hours like 4-5 should be okay for light foot traffic) and another thing I like as well is that the color closely matches the garage floor. I’m not that much concerned about its durability as I’m planning on coating the floor with paint and a top coat after anyway it should seal it good. It’s a bit expensive than others but does the job nonetheless I’m giving it 4 stars.

This product worked as advertised. Very easy to use and turned out great! I did it myself!

Quick and easy to use, and it really does fill cracks! I was skeptical when I bought this powdered concrete crack filler but honestly it’s so easy to pour into the crack and then spray with a little water to set it. I think maybe it’s the same as finely made quickcrete but this plastic bottle & applicator are so convenient to use that I’m willing to pay a little more for the product. I filled a few cracks in my sidewalk last Fall. Most of my repairs lasted through a cold, snowy Winter. Only one needed another application of crack filler in Spring.

This stuff works like a charm!

doesn't work well with small cracks, 1/8 -3/16" is its sweet spot, and if you're trying to fill the all the way to the bottom, it's not economical.I ended up getting a bag of cement for mortar, WAY cheaper and worked pretty good!
