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.

Works well even for larger cracks. Color didn’t match as I expected but my main goal was to seal all cracks and it did a perfect job. Instructions say not to pressure wash so find alternative ways to clean you surface going forward.

First use was to fill in a small to medium crack across driveway slab. Removed all the old repair material and filled with this product. Wasn't entirely sure on how much water to spray on it and put too much. It still dried eventually and seems quite strong. Few weeks later decided to use the remaining product to fix a brick retaining wall. The horizontal and vertical brick mortar joints had many small to medium cracks. This is my own method... Mixed up small amount of powder with water in a metal bowl then applied the thick paste into cracks then wiped away excess. This worked really well for me and when it dried completely the color and texture was nearly perfect match with the old mortar. Wish there was a way to alter the color slightly as it didn't match the concrete slab quite as well as the mortar in brick wall. Would like to comment on longevity of either repair but it's only been few weeks. So far all good. I chose this product because previous attempts with caulking type repairs always leaves me disappointed with color and texture matching not to mention they don't last. Purchasing another bottle soon to fix several long cracks in garage. I'll update then hopefully.

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.

This is the stuff that I was wanting, but I thought it would be a little different from what I’ve gotten before. On the container itself it is labeled, “concrete joint & crack filler,” which is what I was told to order. But the listing on Amazon says “concrete crack filler.” That threw me for a little of a loop because I was trying to get what I was asked to get exactly and I thought I would have to get a slightly different product. Turns out I actually got what I was asked to get.

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.

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.

This is a sick product..rather than do the whole cement thing. This little product absolutely smashed the cracks in my driveways...loves it. Be patines with the steps. Great product A+.

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.

Works great
