ConSandtrate Concrete Crack Filler - Gray - 3 lb. (Single Bottle) - Polymer Based Sealant for Filling in Concrete Cracks on Driveways, Walkways and Patios (Gray)

I purchased the tan color because my patio isn’t new. I figured tan would have more of that “worn in” look I needed to blend in better with the crack. I had a hair line crack on our patio that kept spreading pretty bad. I took a stiff brush to the crack and then I pressure washed the patio. 2 days later I filled the crack in with this crack filler. I took the bottle and lightly went along the lines of the cracks. (The directions call for taking a stiff brush and sweeping the filler across the crack but I had better results taking my finger and lightly dusting it across as I made my way along the crack. I found that using the stiff brush was making to much of the filler spread out everywhere (in places I didn’t need it) and this filler is basically sand and is really hard to clean up the excess because it’s like sand and is so fine. I didn’t want any extra filler setting into any areas that I didn’t need so using my finger was a better control for me I guess. After applying it I lightly misted it with my hose. The next day it poured down rain and I thought for sure this wouldn’t hold up but to my surprise it actually did. It seemed to settle and fill into the cracks very nicely and feels like cement when I run my finger along it. The tan color is a lot lighter then I expected it to be and I’m really glad I didn’t go with the grey color because I’d imagine if tan was this light then grey would have to be almost white. It really doesn’t matter to me because I planned on staining our patio at some point anyways. My main concern was just stopping the crack from spreading and it seems like this will do the trick. I plan on coming back to edit my post next year to see how it does with the colder weather. That’ll be the true test. If it stays as it is now then this stuff is a miracle in a bottle. It’s simple to use and it’s SO much easier to use then that sticky crack filler in a caulking tube!!!!! I’m extremely happy with this so far! Anyone can do this honestly my 9 year old could have it’s that simple. It’s nice to know there’s something out there so simple to use that seems to be so efficient.

It works on holes and cracks! Perfect for my needs. Definitely will buy again for small jobs

This stuff was easy to use to fill in some very small chipped areas in an interior concrete floor. I'll say the "brown" color is pretty light, more like a tan. I ended up using a staining pen and then put sealer over it and it looks pretty good - deducted a point for that. It did dry very quickly and seems to be pretty sturdy.

This is the best concrete crack repair product I've used having used about 5-6 different products.

Installed this 2 months ago. So far so good. Didn’t go overboard with prep etc like it said to. My stamped concrete seems to “breath” with the changes in moisture (rain). So was curious to see what would happen. I can see how epoxy would be stronger / stand up to this better but I wasn’t sure where to find it. This stuff has been fine. If the crack widens because of rain, I just poured more in and rubbed in with my finger and problem solved. Basically I’ve found I could just give this tune ups as needed and it works great. Will literally have a coffee and walk around the slab (2400 sq feet) and just do touch ups if needed (which so far has been very minimal). I just resealed my patio with a solvent based sealer since fixing the cracks and the filled cracks seem to be even more bulletproof now. Only issue is with the sealer the color changed and the cracks stand out more BUT there’s something about the cracks not being actual voids that is acceptable. I’d purchase and use this again. If the cracks shift / open a little I’ll just pour more in. Seems to be well worth the money and so easy to use. Don’t over think it based on the instructions. 2 of the pics are the same crack, one before fixing, one after. It blends well… the third pic is of a fixed crack that has the sealer over it. Definitely more noticeable. But still worth it.

The product worked well but wasn’t as brown as expected, more of a tan color.

I had some small voids in my patio where the aggregate didn’t settle all the way. It is tan and about 95% of the concrete repair out there is gray. I was so happy to find a matching color, AND this stuff works like a charm. Simple to use. Clean the crack or void, makes sure it’s dry. Pour it on and level it up with a brush (old toothbrush or whisk broom works great). I used my grill spray bottle to wet mine. Just make sure it is wet all the way through, but not soaked. It sets up in a couple of hours and is fully hard in a day. Do you have some odd-colored dyed concrete? These folks have like 30 colors on their website. Bet a dollar they’ll be able to match the patch. Made in the USA, family business. What’s not to like? Need concrete repair? You simply can’t find anything better or easier to use. Buy this product!

I purchased this in August 2024 and was very very skeptical about this working as advertised. I thought it was too expensive for what I would be needing. I had a lot of cracks. It has been about 15 months since I used this on several cracks that I had. The longest crack was about 9 feet in length. There were about 6 more of various sizes. As of today, all of the cracks have remained closed with no chipping or signs of new gaps. Two cracks are virtually unnoticeable unless they are wet. I am totally impressed with this product and I still have plenty. I have pressure washed over all cracks at least once without any sign of degradation. This will be the only crack filler I will use again.

That’s a best product on the market to do such amazing job. That’s illustrated in my images about its concrete floor versatility. Well done 👍 developers

Worked great will need to see how it last over the winter.

I purchased the brown version of this product to fill in some cement cracks in my backyard that ranged from hairline-type cracks to 1/4 inch. I had previously tried cement but found it difficult to fill in the cracks without it looking messy. This product works nicely for that purpose and this was easy to use. For slightly larger cracks, the nozzle of the plastic squeeze bottle can be placed into/close to the crack to allow the powder/sand to fill the crack. For smaller cracks, also using a small brush to sweep the powder across to fill the crack worked best for me. The product hardens when you spray water on the powder. I used a spray bottle on a mist-type setting to get the powder wet but not soaking wet. Overall, I was happy with the performance of the product, especially how the cracks were filled in and how the powder hardened. The acid test will come with time once we experience freezing temperatures and get into another summer. I was disappointed with the brown version of this product because it was more yellowish/beige than brown. On the Amazon Canada web site, the only 2 colours offered were brown and tan. The Amazon US web site also offered up grey and white and the brown displayed on that web site is nowhere close to the actual colour of the product once hardened. Hopefully, nature will take its course and outside dirt, etc. will darken the colour over time. The other drawback was the cost, which I thought was a tad high for basically 3 lbs of a sand-type mixture. One might be better off buying a bag of polymeric sand and, to get the same effect as this product, putting the sand into a squeeze bottle. Think I might try that next time, especially if this can better match the colour of my concrete.

I had a hairline crack in my stamped concrete patio and this stuff pretty much made it disappear. I’ll have wait and how it holds over time but so far I’m pleased with the results

Works great
