DAP Concrete Crack Filler, Gray, 1.62 lb (7079860500)

This stuff is great. I ordered it not really knowing what I was getting. I had two cracks that I needed to fix. The ease of use is incredible. Just sprinkle the material in like sand and lightly spray. That's it. I have fixed both small and wide cracks with no issue. It adheres to both smooth and rough surfaces. The size of the container allows you to fix multiple cracks. It is a great value for the money. The only issue you will have is if you are trying to fix a vertical surface. The particles will just fall out before they are wet so you should probably get another product.

I purchased a tube of goop from a different provider and was quite disappointed. It just seemed to "gum up" when I squeezed it out. Just didn't fill well. So I purchased this product to give it a try. Very happy with the way it worked. Easy to fill cracks and smooth then just spray some water on it and voila, you are done. Would definitely buy again.

I had a 10-foot crack across my back patio, about 1/8 of an inch wide. I followed the instructions carefully (highly recommend watching a video tutorial if you’re unsure), and it worked like a charm. I’ll update if anything changes, but so far—despite a full week of rain and even after poking and pouring water over the repair—there have been zero issues. One tip: don’t use a blower to clean up afterward. I made that mistake—the airflow was too strong and blew away some of the material as I tried to neaten up the edges. Instead, use a paintbrush—a trick I picked up from the video. It made a huge difference in smoothing out the surface and filling in the cracks cleanly. Be patient, but the product dries fairly quickly. It was already hard within 3–4 hours. I also tested it on a much bigger crack—between 1/2 and 2/3 of an inch—on my front patio. Once again, it filled beautifully. The product held up strong and even secured small pieces I reinserted into the break. Honestly, this stuff is rock solid.

Works well on small cracks and is easy to use. Would buy again.

Got this to fill some cracks in my garage floor that extended out to the driveway slab. These cracks had been filled before using that self-leveling crack filler, but it was starting to fail. I used a grinder and flathead screwdriver to peel out the remaining old filler and then poured the powder in. I leveled using a putty knife and spritzed with water. Job done. This was in direct sunlight, so the material was fully hardened in less than an hour. I've since driven on it multiple times and i'm seeing no ill effects. I also used this on some spalling on my front steps. Initial results are very good. Color is off, but the patch is smooth and was very easy. This is not the recommended use for the product, so we'll see how this does over time.

Fast shipping, good quality

Works alright. Definitely fills the cracks in concrete, but couldn't seem to get it to cure properly since it was basically hard sand that could be swept off pretty easily. Followed all directions with no deviation. Could possibly be that you need to wait a lot longer when using it in a garage without direct sunlight. I would say it dries quickly, but once again, wasnt as solid as expected once dry time passed.

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 .

This works great, easy to use, sets hard. Will see how it holds up to winter conditions.

Fácil de usar y efectivo!
