Magic Crack Filler 2.5LB Concrete Slab Gray, for Filling in Concrete Cracks on Driveways, Walkways and Patios. Installs Easily Dry Granular No Mess and DIY (Gray, 1)

I bought this product because of the cracks in my sidewalks and my garage floor. Easy to use - pour into crack, push it in with a card or a blade and then spray with water from a spray bottle. Wait for it do dry out some and then I sprayed it a second time. It is the texture of a concrete powder, so mine dried grey as I ordered and no more crac!. It easy adhered to the concrete edges and was self leveling when poured in the cracks. After it set, if I noticed a low spot where I thought it needed a little more, I just poured out the powder and moved it around with a putty knife to get it exactly where I wanted it and then sprayed the powder again. Matched the color of my concrete after drying and in most places it is not noticeable

Works well, although as expected the color is not going to match perfectly. I had a lot of cracks and they were quite large, some an inch wide in places. Since this product is not cheap, I bought a bag of sand for 4 bucks and filled the cracks in except for a a space at the top of about 1/4 inch. Then I topped that off with the crack filler. Misted it and it hardened well, surviving a severe thunderstorm the next day and seems rock hard. Isn't perfect, but better than having the huge cracks. I don't mind doing this over again every couple years if that is needed. Tens of dollars vs $20K driveway replaced.

Works great on the small cracks and so far, this has been the best crack filler that I have ever used. We will see if it holds up over time. Larger cracks can be a little more difficult requiring more product or prefilling with sand, soil or foam. It is easy to use and takes only a small amount of moisture to activate. Blends well without uneven ridges.

Easy to work with and has done a great job closing my many small concrete cracks. Just prep surface good, pour it in, and I use my paper business card to smooth it out. Spray and done!

I saw this product advertised at the National Hardware Show. I received a sample to try at my house and I liked it so much that I ordered this larger bottle. In my opinion, it works and looks great after application. It’s not perfect, and the color does not match my concrete perfectly, but it looks loads better than the empty cracks that were super obvious. Application is so easy as it’s a powder form that you can squeeze out of the bottle into the crack directly. After I poured some into the cracks, I used an old credit card to carefully flatten it and get the majority into the crack, as opposed to all around it. I used a mallet to pound the concrete all along both sides of the crack and refilled areas that sank. Once everything was smooth, I followed the instructions and sprayed with my mister spray bottle. A squirt bottle would create too much force and dislodge some of the material if you’re not really careful. I prefer the mister applicator. I don’t know if I’d call this self-leveling, as I had to use my credit card to level and smooth the product. It instructs the user to spray the product with water every 15 minutes for an hour, so I just set a 15 minute timer each time I sprayed. It dried quickly and feels quite firm to the touch, though they describe it as a rubber-type, pliable firmness. My biggest goal was to make the cracks on our porch look better, but also prevent water from getting further into and under the slab of the patio when it rains. I think this will do the trick, even if it’s not “watertight.” It will prevent water from soaking down and allow it to keep moving across and off the edge of the slab. As far as appearance, it’s weird how having the gaps filled in makes your eyes gloss over the cracks, it looks much more flat and even, even though you can still clearly see where the cracks exist. P.S. We have filled cracks in the past with liquid products and they look horrible compared to this. I highly recommend this product.

Love this stuff! Drys to color match great, durable to rain and NC weather but it is super expensive to full-on the deep cracks on my back porch 😔

This stuff seems to work pretty well on an 11 year old driveway . I didn't bother to cut the tip off as there wasn't a cap included with the bottle . So I poured a small amount of the contents into a small sample size cup & used it to apply the product into the voids & cracks of our driveway . This has the consistency of a fine sand so working it into cracks is easy . The color is also consistent , well as long as you purchase the appropriate color to match your concrete driveway/sidewalk . Judging by a review picture , I'm not alone in ordering & applying the tan product to a gray driveway that was dyed with a slight yellow tint , but you wouldn't know it . For applying it to cracks , just try to not over fill the crack & get enough product along it so there's no need to use a credit card to move the excess along the crack . A soft paint brush will sweep too much material out of the crack/hole unless the brush is used at a very steep angle . Unless you don't mind trying to remove the excess after it's dried . Also as far as holes are concerned wetting with water the hole before filling it works much better than just filling & misting . The later application causes the filler to raise up plus depending on the size of the hole once wetted the filler will compress down & more filler will be needed . The instructions say to re-wet every 15 minutes for an hour , yeah hello . I did it for almost 2 hours & the cure time is like 48 or more hours . Instead of using a rubber mallet to get the material into a crack , using a Sawzall without a blade on top of a block of wood , rubber mat or cardboard should help to vibrate in the material & keep from damaging the concrete . So now the fun begins attempting to remove any excess & not damage the finished look of the driveway by using a fluted rubbing block . The next step in my adventure after performing the above tasks & ample drying time is to apply a good coat or 2 of & I"m using Armor S2000 Sodium Silicate concrete sealer / surface hardener . Plus if needed a coating of stain to attempt to not only hide my screw up in color choice but to also make the driveway appear better . Followed by the cherry on top of applying a Ghost Shield Siloxa-Tek 8500 Ultra concentrated penetrating sealer . We live outside of Wilmington NC where there's almost no chance of needing a winter salt deicer but in the advent of an oil or gas spill , the driveway should not stain . Is all of this necessary , I think maybe , maybe not but being retired does come with some advantages as in being bored & a lot of free time .

Used this last week. Very easy to use, fast and No mess. Be very exact when you pour out the powder product in the crack. Then just Spray/ Mist with water to firm up. Dried as expected. I used Black on the asphalt and Tan on the concrete. Take your time and be careful with tan color to stay in the crack. Camouflaged. Looks very good. Takes more product than expected with Asphalt especially. No clean up needed.
