In this video I'm showing you step by step how to repair cracks in a concrete floor. I'm using a repair product called CrackWeld from RadonSeal.

This easy to use, diy concrete crack repair kit will make fixing your cracked concrete very easy.

All you have to do is clean the crack, remove any dirt, debris, and dust by using a vacuum. You don't need to rout it out. Put the repair kit together like I do in the video, purge a little material out into a cup, then start "wetting" out the crack. Add silica sand to the wetted crack and mix it into a paste using a putty knife.

Force the "repair paste" into the crack, moving along down the crack. Leave the repair material a little high, you will be lightly grinding it off to smoothen it and make it flush with the concrete floor.

The step by step instructional video will show you just how we repair cracks in a concrete floor.

I think I might return the big box store epoxy. I'm glad you are here and you are such a knowledgeable guy!

Thanks for this video and taking the time to explain how to DIY repairs like this, and leveling - it helped us fix our own problems in place where it's hard to get professionals to bid projects. :)

Mike, I just discovered your channel today. Awesome videos.... many apply to me DIY... especially stamped concrete. The final repair of the cracks in this video look great. I scanned through your videos looking for concrete driveway repair to no avail. Do you have a video 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.

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

Hi Mike, I was wondering where you purchase your sanding discs for cleaning off the top of the cracks once the material is cured? Thanks Rich Thompson

Hi Mike, nice video. 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?

Hey Mike - thanks for the video. If the homeowner was putting flooring over those cracks would they need filled? Or was it because they were just gonna add a clear layer over it?

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.

Great Video 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 watching a video 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.

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.

Is it possible for the concrete floor to crack even after the epoxy? Does the epoxy prevent concrete crack?

Did you chase the cracks first before applying the CrackWeld?

Will this product work on a broom textured concrete driveway in Florida?

Are you supposed to only fix bigger cracks? I have very small ones, barely a millimeter wide? Should I open those too and fill them up? There are lots of small ones. Thank you.
