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.

I almost didn’t buy this due to the reviews. I found it easy to use, and it filled the cracks in my cool pool deck well. I used the product 2 weeks before staining and it did not wash away as some claimed that it did. You can not tell that there were any cracks after stain application. I would use this product again.

I bought the tan color because I have a tan colored stamped concrete deck. It was far too light (it looked like I just poured beach sand in the cracks 😆) so I bought the brown to go over it. Pictures shown are tan. Brown seems to be a better match; I’ll update when it dries. I scraped out the cracks, blew them out with an air compressor, then vacuumed them before filling them. For the deepest parts I filled with play sand on the bottom then this product on the top. We unexpectedly had rain just a few hours after this application and most of the sand product stayed put!! Some of it did wash out or settle during the rain; I just topped it off with the brown color after it dried out. (pictures to come). I also just saw that this company has 30 colors available on their website, so if brown isn’t close enough I’ll try again with a different color. Application is easy, I’ve just been pouring it on and brushing it in place with my fingers. For spillover past the crack it works well to cover the crack with my hand/fingers and blow away the excess. This product does look lighter when it’s wet—right now it’s been raining so even the brown color I applied on top yesterday looks lighter because it rained this morning but I think it will blend better when everything is dry. Overall very pleased, much easier and less messy application than caulking. I wish the color match was a bit better but that may just take finding the right color. I definitely plan to finish filling all of the cracks on my deck with this product and may purchase more in gray for my driveway after that.

Great product for filling cracks on my aggregate driveway

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.

Thought this was a great product because it does exactly what it is supposed to do. I ordered 1 bottle of the gray and 1 bottle of tan to see which was a better match. The tan was perfect, so I ordered 3 more tan….I used 1 of the new bottles of the “tan” before I realized that it was much more gray than the first tan bottle. So now it doesn’t match the original tan repair. The other 2 new bottles are also more gray than the original. Very disappointed cause it did fix the cracks just doesn’t match.

Works great

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.

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

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

Excellent for our exposed aggregate driveway! We chose brown. I used a stiff dry paint brush to assist in working into the cracks and brushing away excess. A mister spray bottle to initially set it before going in with our hose on mist setting to ensure it stayed in place. It dries firm, but with flexibility for movement. Highly recommend! Much more DIY friendly than tube or mixed repair products. Very pleased! Will repurchase.

I had a driveway poured about two years ago. Pretty disappointing that it has cracks already but it is what it is. I tried a few approaches and was wary about this stuff. Finally gave it a try. I have not gone through a winter season with it yet but through spring and summer it has been flawless.

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.
