Hi Scott, I've been watching and re-watching your driveway garage to driveway and sidewalk crack fixes cuz I've never done it before and I want to be confident in what I'm doing. Are the products you recommend ok to use in buffalo ny because of the bad winters, etc? Also, when using the self leveling stuff over the pool noodles ( backer rod), do you fill the crack up to the top or just below? You said regular play sand ok but man at home depot said silica sand like for making stone walkways,etc. ( I'm going to wait to get your answer first before I get anything). I have many trouble spots to fix. Tia for answering me! I'm going to have to keep re-watching 😂 have a great day!

[@EverydayHomeRepairs]

@@kellyr6274 Hey Kelly, I would fill the crack up to just below the surrounding concrete. My favorite sealant is the Tremco 45 SSL but the Sika Self-Leveling is good stuff as long as the crack has no slope. You can use pretty much any sand you want as you are just filling up the voids under the concrete. Just start on a crack that is less visible to get a little practice. Best of luck, you got this 👊

I've repaired cracks like this myself. I enlarge tiny cracks, blow out loose material, blast the crack with water hose or pump sprayer, let it dry using blower, fill crack with dry mortor,level it, then wet it with a pump sprayer, tool the surface to compact it. Works every time.

[@jameslester4474]

I'm going to give you all a tip on product use. The Quikcrete product in the bottle will dry, hard and will pull away from even properly prepped concrete, when it moves seasonally. The other products do about the same and I've had failures at one or two years with all but the product I'm about to tell you about. Don't laugh though. Clean and prep your concrete , you can even carefully use a wire brush, or pressure wash the cracked area a couple days before the repair, make sure it's dry. Backer rod when used properly, needs to be down in the crack, not just below the surface, remember the concrete is cracked ALL the way through the thickness, so get some product in there to stabilize the crack, not just a dribble at the top. My secret concrete crack filler product is... Grey Flex Seal ! Yep, the stuff from T.V. I have used a large hobby syringe to draw the liquid Flex Seal from the Pint, or Quart can and just let it flow into the crack. It will self level very well. The difference with using Flex Seal is, it is Liquid Rubber, so when the crack joint moves, and it will, the Flex Seal will flex, and not pull away like the other products do. Flex Seal sticks to the clean Concrete really well. And it Stays Flexible for years. I repaired my first driveway that was full of cracks about 9 years ago, and it is still as good today as the day I finished. You can sprinkle some sand in the Flex Seal right when you put it in the crack, to help blend it in if you want too. I installed a new sidewalk at our new home last year, and used the Flex Seal on the Sidewalk Expansion cuts, to keep water out, and it looks beautiful. No, my name isn't Phil Swift, and I do not work for the Flex Seal Company in any way ...

[@FragEightyfive]

Great intro and explanation of how to do this Scott. I did this on a number of client concrete patio / walkway / driveways in the early 2000's through 20-teens. The first ones from 20 years ago are still holding up! Like other forms of sealing - painting or other forms of calking, it is 80% prep. The most important thing is to follow the directions on whatever product you use! I think the second or possibly most important part of this procedure is to know WHY the crack formed. Many times there is poor drainage so there is soil erosion and frost cycles.. Is this crack going to continue or new ones going to form? Easy to solve when there is a downspout next to / near the concrete - get that water further away, re-route the downspouts, install a french drain if needed to help lower the after-rain water table. Where I have done this the crack stopped widening, and the sealant has held up for in upwards of 20 years!

[@Mr.old-school545]

Just fill it with hydraulic grout. It's not going to shrink.

[@PeterShipley1]

I usually run a grinder wheel the length of the crack. followed by a wire reel. to make sure the sealant can get into it, and then I covered with sand for two reasons. the first is the blend in the second is the the sand provides protection for the polymer sealant

[@Peter-fo4ec]

[@briangregus5225]

Visually, and this could be the video, I think your other repairs have blended much better. Will this product become more mottled, and thus blend better, over time? I wonder what additional methods the sealant could accept. It's funny, the larger cracks seem easier to address. Your pool noodle trick was excellent by the way. Found yourself the super sized backer rod!

[@gregwhite-jo1dj]

Scott. Thanks for the videos. I have a Concrete backyard in New Orleans La, I have repaired several cracks with the Sika product,, Gray Formula. The Concrete was stained a mid to light green and has faded where the area closet to my house was covered by an aluminum cover. The rest of the concrete, whir a majority of the cracks were fixed, was exposed to weather for the last 15 plus years. I have repainted the house with a light tan paint and have beechwood brown roof and am contemplating restraining the concrete with some shade of blight brown or tan. First, I want to make the area where the cracks were respired less visible before possibly applying some form of covering paint across the entire concrete area before appoint any brown stain or paint. Can you provide any ideas?tips on making the entire area uniform in appearance before the final steps of my project? Thanks, Greg W

[@brandym.williams7314]

Is this repair viable for cold winter climates? You carved out the crack and only put the backer rod in 1/4". Wouldn't it be possible to get water behind the backer rod, freeze and blow out the crack making a larger repair?

[@John-NeverStopLearning]

Good things first. Silkaflex is a great product, don’t use on any slopes. I have not used the Tremco, nice to know it will do a slight slope. Bad part. The plastic bottle I have tried to use. The issues I had were, shaking it does nothing. There’s a lot that settles in the bottom that will never loosen with shaking. I have tried a spade drill with the point and corners ground off. This works well however there always seems to be lumps in it. It does not come out of the bottle very well when squeezing. Good information on the video 👍

[@marshallwilensky7932]

I shook my plastic bottle like crazy. Since I had never used the product before, I thought it was supposed to be that thin. Later on, when I tried to seal another crack, the bottle was obviously still pretty full but NOTHING came out. I cut the bottle open and used a putty knife to trowel the product into the crack. So far it’s been okay. In the future I will use any other product.

[@andreii.6094]

I wonder, you showed that really wide crack which you filled with Tremco 45 two years ago.... What was the reason to fill it with Tremco, and not with concrete? I totally get it, filling a thin crack with concrete can be challenging, but a gap that wide should not be difficult?

[@inglouriousmofo]

Just going to crack again

[@tashrayt4398]

I’ve used this method on my driveway. Asphalt. After a few years the cracks start to expand more and they open up.. leaving you with another crack next to your sealant. I believe one step id recommend to prevent this is to bind the sealant to each side of the crack, so smooth it out with a putty knife for example, so it isn’t just sitting in the crack but also is able to bind to each side. If you don’t then you’ll end up with my issue..

[@demonovationable]

I don't see anywhere that states this product is formulated to work on asphalt. It's possible the petroleum in the blacktop could inhibit the cure of the sealant. Always best to use products specifically formulated for your substrate.

[@tashrayt4398]

@@demonovationable it was actually a more superior product. Either way I’ve used this on concrete walkways and experienced similar results after a couple of years.

[@demonovationable]

[@garyz5456]

What about the powder sealants like DAP makes?

[@robertarnold9815]

What you want to do (and he is doing it) is get the correct "shape factor." If you go too deep the adhesive capacity of the sealant can't hold on to the sides. It’s sort of like a rubber band if the shape is deep and narrow there is a lot of stress on the edges, while if its shallow and wide there is less adhesive adhesion stress. I just watched it fast to see if he would give the explanation of why you do this prep.

My method might be overkill but I would grab a bag of Cemetall (very inexpensive) and put it into the crack - just the dry powder, no water. Fill the crack with it but leave about an inch from the top of the crack. Then, mix a batch of Cementall with water to make a watery slurry. Pour that into the crack above the dry powder but again, don't fill the crack all the way. Leave yourself about 1/2" to 1/4" from the top of the crack. Let that dry for 24-48hrs. Finally, use the Sika or Tremco to finish it off.

[@akbychoice]

If it isn’t flexible, any expansion might crack that product. This is why expansion joints are needed to prevent buckling.

[@JtotheRizzo]

​@@akbychoice The crack appeared away from the control joint in this particular video. This tells me the base (below the concrete pad) failed or eroded away. The CementAll is not meant to provide flexibility but to give strength to the base. The Sika or Tremco is the flexible component of this repair. Once a crack appears, it's not IF it will fail again but WHEN it will fail again.
