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)

It actually works and it’s easy to use. It looks ok just make sure to get the right color. It covers well on small cracks

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.

The first 2 times i used product was good. The product powder is good but this delivery was horrible. There was no packing material in the box and the AAA batteries i ordered were pkg with the concrete. I opened pkg batteries were every where and damaged. The spout on one of the powder containers was severely bent and the two powder containers had no red cap to reseal when opened. Thankfully AMAZON REFUNDED ME FOR CONCRETE AND I AM RETURNING THE BATTERIES.

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

This stuff actually work if you use it correctly. FOLLOW THE INSTRUCTIONS EXACTLY. It’s raining today so the picture doesn’t do it justice. This was a pretty big crack, and unfortunately a thunderstorm rolled in unexpectedly late in the day, but it is holding up nicely. I had a crack on the back patio. You can’t even hardly tell it was there.

Easy to use. Followed directions. A few days later hairline cracks are appearing

Great product. I had several little holes and pits in my concrete driveway. Cleaned the holes with alcohol spray and vacuumed out the dirt and debris. Applied the powder liberally, then flattened and smoothed it with a trowel. Sprayed water on it 4 times and waited 20 mins in between while doing something else. It dried out the next day and hardened like the surrounding concrete. It blended in very well with the raw concrete color, too, so it's noticeable only if you know it's there.

Works great. Very effective, especially on small cracks.

Works great! One tip I’d suggest is to prefill the crack with fine sand several times until it’s almost full. Then use the product for the finish top coat. You’ll use less

This was very easy to use and worked great.

Color is a bit off from the description. Will do another coat next spring

This is a very very fine sand like substance. Good for small cracks. You wet it with water to cure. If you use it on large cracks, you’ll go through the product quick and it’s expensive. For me, it didn’t match the concrete colour, it is way lighter. My next attempt will be with the sand used to bond paving stones. I’m guessing this is the same stuff and a bag, 25 kg has a lot more and is half the price. I have yet to see if it will stand up over winter.
