DAP7079860500 Concrete Crack Filler, Gray

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.

I'm very pleased with the DAP concrete gap filler. I didn't have high expectations, given the width of the cracks I was filling on our garage floor and based on some of the other reviews. However, the application was quite simple and I'm very pleased with the results thus far. I have multiple pics of before/after, but I'm not able to attach them to this review, for whatever reason. It's a shame, because pictures tend to tell the most complete story. I have purchased a second bottle of the filler, since it worked so well for my application.

I have used other brand name driveway crack fillers/sealers and the application of this was considerably easier. It comes out in a dry powder, so you cut the spout size to match the cracks. The directions suggest either a flat-blade knife or a paintbrush to level and smooth it; I used both and prefer the brush. Once it’s in place you simply mist it with water, either from a sprayer or your garden hose. Then let it set up.So far so good, but it’s only been a few weeks since I got my first two bottles (I bought 6 and have half of one leftover). That’s why the 4 stars. I’ll revisit this a a year.

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.

I ordered this fill some cracks in my driveway and, this stuff is amazing. filled in the cracks perfectly and, it's so easy to use and, dries quickly and, took me about thirty minutes to fill in about six cracks in my driveway. I had just enough product to finish my job with a little left over... I would recommend this product to anyone needing to fill in some cracks in a side walk or your driveway.

if you prep the area porparly , it works perfect. It fixed my wobbly railings and cracks in my step slabs perfect. However. don't expect a color match. It was fine for me because i painted my step slabbs with nonslip paint... Be prepared to see it's not full to the top but the weight was correct.

Was not expecting this product to be better than the DAP Bondex liquid cement filler, but it is. Unlike the liquid the powder actually fills the crack. Tricky to apply at first, but after some application it looks better and does not require a second coating.

Had a couple hairline cracks in my patio that I needed to fix before repainting. Product was easy to use but feel like you needed to almost run two layers of this to really seal the crack. After waiting a few days for it to cure after the second coat I did a light 600 sand to help prep the surface and it helped fill in about 80% of the cracks. After painting, you can still see where that last 20% did not seal all the way. Overall it did improve the look of the patio.
