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

The DAP Concrete Crack Filler is a fantastic tool to easily fill and repair minor cracks. When applied and solidified, the filler looks good, fills cracks so weeds cannot grow through them, feels solid, and doesn't seem to erode away. I patched the cracks in my backyard concrete, and the filler has withstood rain, California heat, and normal backyard traffic from our family without eroding away. It's really easy to apply - simply pour, use a spray bottle or mist setting on your hose to dampen the crack filler, and then allow the filler to dry completely. The filler fully fills in and covers the crack, and I had no issues with the material spreading or getting everywhere. If your cracks are large, you can drop some pebbles in to fill the gaps in a bit more before pouring in the filler. I loved how easy it was to patch these smaller cracks and how easy it was to level them out. To utilize the filler without wasting it, you can also use a small paintbrush to spread the filler before dampening. It's quick, clean, and takes very little time to patch your sidewalks. My only complaint about this filler is that you can go through this stuff fairly quickly if your cracks are deep - but it works so well and so convenient that I ended up purchasing more. It would be nice to have it sold in bigger containers. Overall, it's a great product that I will be purchasing again when I need to patch a crack in my concrete.

I used this on a cement water drain like the ones on the freeway on the hillsides, but mine is horizontal. It is amazing how well it works and far better than anything I have used before. Silicone or caulking do not compare to how well this will hold up to the elements on a flat surface. I pulled several feet of those materials off the area where I used this product. I used a spray bottle to wet it lightly and was amazed how it looked and felt after it dried for 24 hours. Buy it.

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.

I love this product! It was easy to use, and clear instructions. It gave me the results I was looking for. I wish the product came in larger sizes, but I used several to clean up by driveway. I will buy more someday for my sidewalks, and other areas around my home.

Worked great for a season but had some minor separation in the crack Not the products problem as the slab is still settling. Suggestion if you are using this on an outdoor slab or driveway, with rain runoff some of the light grey color will leach out and stain the surface. It might appear permanent, but just use some cleaner and a brush and it washes away. Still worked better than the messy liquid crack fillers for hairline and thin cracks

Used this product to fill drive way cracks and small round holes all last summer and fall. How did it hold up? Well on the small devits its great, filled & water, still great. However, every crack line (from a quarter to half inch) did not hold up at all. its all cracked up and have to figure out what to use. Cost is good, driving time good, even looks good, but does not hold up to seasonal changes. So, I might try a liquid filling product.

The DAP Water Activated Concrete Crack Filler has proven itself as I have a cool deck adjacent to my in ground swimming pool. It’s quick to set and super easy to apply. Even a non do it yourselfer can easily use this product successfully. I found that there is no shrinkage and it dries pretty quickly. It’s perfect for small to medium sized cracks. It works as advertised and I’m happy with the results.

I have ordered this 4 times because it works so great to fill cracks the only downside is the bottle is so small and I have a lot of cracks, but I would continue to order it over and over. It works so great! It’s very easy to use and it dries really fast and the color matches the concrete perfectly!

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

Fácil de usar y efectivo!

Think imthe oroduct was out of date

This works well as specified. Follow the instructions, I used it to fill small pots sections and they hardened as expected.
