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!

@helenstergius 7 месяцев назад

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. :)

@aaronbrown3573 5 месяцев назад

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

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.

@rauten6588 4 года назад

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 have a 1/2 wide crack in my floor (just pulled up the carpet). It looks fairly deep and one edge is higher than the other. Can I use this product for this?

@MikeDayConcrete 3 года назад

You can yes. You'll want to fill the crack with some backer rod foam first, leave it down about 1/4 to 3/8 inch, then use silica sand and crackweld like we're doing in the video to fix.

@njsmama1 3 года назад

Thank you!

@amagicforest 4 года назад

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.

@MikeDayConcrete 4 года назад

Thanks John!

@PanyingPilot 4 года назад

Mr. Maloney was using an ad hominem attack. This is a logical fallacy whereby one attacks the character of the person rather than the actual issue. In these tense times, it is the mark of the better man to rise above it. Congratulations....and I appreciate the tutorial. I have work to do.

@joejones56 Год назад

Why not just chip it out until it’s good and refill with concrete? Is this stuff stronger?

@stevepeters1003 6 месяцев назад

Wouldn’t control joint cut into the floor help avoid those cracks from happening? Just saying.

@darrell1469 11 месяцев назад

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.

@KyleTO7 2 года назад

Is that concrete on the top level of a house? I'd never imagine putting something so heavy up on the top level if there's just wood to hold it up. I would basically expect a crack to come. I'm no expert tho.

@jamesfarnham5507 Год назад

You recommend the Dewalt Grinder, DEWALT Angle Grinder Dust Shroud, 5-Inch (DWE46153), but it looks like you're using a different grinding machine with two handles. What specifically is the brand with handles in your video?

@beauchampfrancois151 Год назад

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.

Why were there cracks in the floor in the first place?I was led to understand there should be an expansion joint in a floor that size🤔

@MikeDayConcrete 4 года назад

Concrete cracks, homeowner did his own floor. Just shrinkage cracks/stress cracks. No problem to fix, we're applying an epoxy coating over this one.

@nainka11 4 года назад

Agreed........But we have to assume for the purpose of the exercise that has been done. Or that would be another vid...........Maybe a good analogy would be "how to replace a fuse"......One would have to assume the cause(appliance) has been checked first.

@alwe4472 4 года назад

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?

@Allenking3782 Год назад

If there is a crack it is for a reason. There is an underlying issue that is not being addressed and this is only temporary, it will return. Also second floor cement? Must be a condominium

@amandamartinez6115 5 лет назад

Hey, Mike. We just wanted to come back to your video 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.

@MikeDayConcrete 5 лет назад

It will eventually blend in on color. There's nothing you can do that won't make it stand out more. You could epoxy it to hide everything.

@tehilamilenewicz202 Год назад

We are repairing our concrete floors. Question, there are many cracks and the floor is uneven in some areas. Do we repair the cracks and then do a self leveling mixture? Or the the mixture first and then repair the cracks?

It will fix those cracks. But if there's that much water coming up, it'll find another way. The crack would have to be dry also for you to use this repair material.

You can. It cures very hard. As long as the cracks isn't active, it'll work just fine.

@KyleTO7 2 года назад

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

@slammyfrommiami 3 года назад

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?

@johnkoch6433 2 года назад

Metabo grinder with dust guard will do everything you need. Your shop vac won’t fit on it but you can tape it and it’ll be just fine
