Concrete cracks can be caused by various factors such as temperature changes, heavy weights, and dropped objects. To fix these cracks, there are four main methods: using simple concrete glue, filling the crack, grinding the concrete surface, and using a concrete floor grinder. Before grinding the concrete surface, clear out loose concrete and debris, mix the mortar, fill in the hole, and level it to blend it in with the surrounding area.
For small cracks and holes, use a concrete patch compound, trowel or putty knife, gloves, and sandpaper or sanding block. Patcher Paste is a great way to fill cracks and holes in concrete before applying epoxy, as it will cure quickly. Concrete floors are tough but can still get damaged, especially as they get older.
To repair pits, holes, and cracks in concrete and anhydrite floors, follow these steps: 1) Apply an epoxy primer for concrete, 2) Fill the crack with an epoxy paste, and 3) Ground the concrete again to ensure proper bonding.
To clean out joints, fill them fully with polyurea or semi-rigid epoxy. Repairing damaged joints will ensure an even surface and prevent further damage.
In summary, cracks in concrete can be repaired using various methods, including using simple concrete glue, filling the crack, grinding the surface, using a concrete floor grinder, cleaning and preparing the surface, mixing the filler product, and final cleaning up. It’s important to note that cracks in concrete can indicate deeper problems, so it’s crucial to find the right method for your specific needs.

Curious your thoughts on this method versus using cabosil? My first thought would be your method saves more product as you can make smaller mixes. However, it seems like it takes longer as you make multiple mixes. Also, with cabosil if you get all the excess off there is no need to grind. Thanks in advance!
Hi Mike, nice article. I have a contractor who has leveled my floor however has left it with a few imperfections. I would like to have an indoor concrete flooring in a grey color. In my inexperience i see 2 ways. One: re-level the floor with a coloring pigment and then use an epoxy coating. or repair the imperfections with a kit and then use a concrete colored coating which might be a cheaper option. What do you think?
Mike, I just discovered your website today. Awesome articles…. many apply to me DIY… especially stamped concrete. The final repair of the cracks in this article look great. I scanned through your articles looking for concrete driveway repair to no avail. Do you have a article for this? I have read many different solutions that do not look professional in matching the concrete; it still obvious of a crack even though you may have sealed the problem. Do you have a preference of products and suggested repair method. Thank you Mike.
The carpet guy asked if I wanted to fix floor crack by caulking or cement. I didn’t know, so I thought cement would be best. He made quick cement on the floor and wiped it over the cracks and let it dry. Should a floor guy go back and have it redone with your method then put epoxy flooring on it? Thank you.
Wouldn’t something like a thin liquid epoxy do a lot better so it can go down deep into the crack/pores? Then cover it with some cement and it’s done? I gotta crack in my basement I’m looking to fix. Luckily it’s not that big, just a hairline. Still, I don’t want any raydon or anything coming outta it. Gotta crack line on the front entrance outside the house. On the porch. House is only like 10 years old, high quality development in Canada. I’ve lived in houses that were 40 years old and didn’t have any cracks like this. Sorry for all the comments. It helps with the algorithm anyways for more views :p
I use same idea but different product. Also adjusted my application, I wet the crack then pre mix my sand and epoxy into a bucket then apply. I’m usually doing larger cracks and doing it alone so this way works more efficiently for me. I never understood mixing the sand in the crack ” as is needed for larger cracks ” and at times I’ve had the epoxy not come out at the same rate from each tube and it created areas that wouldn’t harden. So I just started emptying both cartridges after getting crack into 2 quarts of sand and mix it up. I’ve had no hardening issues since. Obviously for hair line cracks i would change my application
Great article Mike, as you stated it is a repair. Some people seem to take issue with your use of a product but I’d sooner know what your using. There is nothing worse than perusal a article and knowing what the product is. As for Larry Maloney he seems to be a little upset, but at the same time he seems to offer no better solutions to the issue.
Good morning. A lot of my basement floor cracked due to water coming up from a broken sewer line. That line has been replaced by the cracks are much bigger than the ones you are repairing here. Would you still recommend this product or would you go for something heavier duty? I’ve also taken care of any other moisture issues by having a french drain installed on the perimeter of the basement.
Hey, Mike. We just wanted to come back to your article and say thanks. We did Order the Radon Seal and we used it on the job and it worked amazing, however when we were finished sanding it you can see the sanding marks, is there something to put on it to make the coloring blend in after sanding. We also ordered some tools yesterday off Marshallton and used your coupon that you told us too. Thanks for that.
What grinder did you use? I need to do a bunch of cracks but cannot clear the basement of belongings in it. Will I be able to grind off the high spots without getting dust all over everything? I have a Shop Vac that I assume I can attach to the appropriate grinder you recommend. Also, I will not be able to do the whole basement in one session since I will have to move some stuff around. Do I need to get extra mixers or backflow valves so I can do multiple sessions?
