Asphalt Sealant

I haven't seen this go through a Winter yet but here's my history of using driveway crack fillers. I've used the melted in stuff. I've pounded in the cold asphalt. I've used the latex cold pour garbage. I've used trowel patch. They all claim to have elasticity galore. Within about two months, before Winter even begins, they all fail. Some of the melt in stuff remained in place but after that hardens over time, it too fails. You also have to be sure to melt it thoroughly. THE ONLY ONE TO LAST THIS LONG WITHOUT ANY FAILURES IS THIS STUFF BY SIKA!!!!!!! I've filled big cracks and small. Once cured, if you push on it, it acts just like rubber!! It adheres like rubber! It's been though the hot full sun and the colder early mid Autumn nights and so far, no failures!! If it lasts the Winter, I'd say it's about as good as the hot rubber melt in. For larger cracks I do use the foam filler because there isn't much in a tube so big cracks will use alot. But the stuff is amazing. Sika is serious about it's products. Will update next year if I find problems but so far, it's proving to be the best crack filler I've ever used. I'm not paid for this review. I'm just shocked at how well it's doing after years of effort, false claims and wasted time. Be sure though to clean out the crack thoroughly. I use a wire brush to abrade the surrounding surface and try to brush out as much dust and debris as I can but the abrading I think makes the difference for bonding. Just saw complaints about how shiny it is. Wait several days for curing, then take a lightly abrasive sponge and lightly scuff the surface. It will dull it down. In time, it dulls anyway. UPDATE AFTER FIRST WINTER: When a crack was properly cleaned out, it lasted. Because I had debris of other failed driveway patch such as areas of trowel patch or even cement epoxy around the edges of cracks, some areas did fail but that's due to my fault. We were rushing to get it done due to other Summer work we had to do but many of them didn't fail. I just ordered another 6 pack. To be fair though, I advise that if your driveway was a patchwork quilt like mine, get onto youtube and look up how to do diy hot asphalt crack filling. There are people on there who heat up the box of hot rubber crack filler you can buy at home depot ($43 for 30 lb?), make a spouted can out of a coffee tin and attach it to a metal post to pour hot rubber into cracks and they end up with a very nice job. I have other jobs this year so am using more of this but if you have a ton of cracks, try the videos on youtube. Fix it with Cronk is one of the guys. I'm not paid for giving that info. Update #2 After further investigation of cracks, here is my recommendation in order. 1. For alligator cracks or ones that aren't too wide or deep, thoroughly heat the melt in stuff after cleaning out with wire brush and blowing out the crack (I use the heat gun). Then melt it in so it's literally dripping. Where the adhesion is needed is on the sides. Drip it onto the sides and fill to JUST BELOW the driveway surface. That's on the directions, which I never bothered to read. I have pulled out unmelted stuff which is why the crack failed. Six years later, a badly alligatored patch that I used the melt in to fill is solid as a rock. My husband used a propane torch on that. READ directions. 2. Hot rubber for large cracks - I haven't tried it yet but is likely the best filler for the larger deeper ones. 3. Sika - adheres well, very flexible, like rubber. It's longevity is largely dependent on how well the surface is cleaned. I've been smearing it over the top of the crack for a smoother look. I think it's supposed to fill inside the crack, not be smeared smooth. When product is left on surface, it may be prone to failure. Sika buys you some time while you use the other two options but isn't going to be as strong as them. 4. Trowel patch.. would only use in an area that doesn't see alot of sitting water or hot afternoon sun. Will last about 2-3 years and then break off in bits, look bad and be a pain when you want to use something else and have to spend time chipping it away from the crack. But it does smooth things out nicely, for a little while.

This stuff is impressive. When applying it is self leveling and will run into every crevice, so it is recommended to use some foam backing rod in order to reduce the amount leaking deep into cracks. I applied this in the spring and has held up very well, staying rubbery/stretchy while actually curing unlike the cheap crack sealer found in the box stores. As usual performance is based on how well you prep the cracks, I dug all the dirt/weeds out with a flat head screwdriver and cleaned the area with a wire brush to get the crud off. This is important as it allows the stuff to bond to each side of the crack making a permanent seal. If this stuff holds up through winter I will be thoroughly impressed. So far this stuff has performed fantastic.

Worked great and easy to apply.

I've previously used the gallon jug of crack filler from a big box but that tends to be difficult to manage (you have to hold up the weighty gallon jug of stuff) and hasn't done a great job year over year. The purpose of crack filling is really to inhibit water from getting in cracks, freezing during the winter and expanding the crack, not so much to actually "repair" the crack. So this year I decided to go another direction and found this product. First, it's much easier to apply more finely than the gallon jug of stuff, because the product size is smaller and also you can more accurately dose with a caulk gun. Second, it flows a lot better than the big box filler - I applied this for the first time on a ~ 75F day and noticed that I'd have to refill portions I'd already gone over because the product was flowing down into the crack. Unfortunately I have several cracks, some of them wide and deep so I'll have to order a LOT more of this. Other pluses I noticed were that the product tends to lose its surface tackiness and plasticity pretty quickly compared to the other stuff. This product flows into the cracks more readily but also firms up quicker. The other product seemed to stay plastic (flexible) for a long time after application especially in warm weather. Downsides - it's pretty expensive for what it is vs. big box stuff, but if it lasts more than a couple seasons, it's worth paying extra especially in reduced labor. Also, if you're applying a lot of this, use of the caulk gun can get tiresome. Lastly, one of the 4 bottles I ordered initially tended to leak out the back, gunking up the plunger on the caulk gun. Not enough to be a giant mess, just a bit of a hassle. Let's hope this product performs better than the off the shelf stuff.

This is way better than the crap they sell in the local hardware store. I’ve used Sika products for installing windshields and it’s a great product Worked great on our driveway.

I'm super happy with this as a crack filler, it starts out like a somewhat thick liquid that flows down and out to a smooth surface, then hardens into a rubber-like consistency that seems to hold up well to vehicle and foot traffic. Will definitely buy again.

I use this for my walking shoe heel rebuild . This cures very slow and you should only go about a 1/4 inch build . Plus let your shoe set for a few days before using . Was tired of my walking shoes soles being wore out in 6/8 months and uppers like new . This saved the day . Started putting a thin coat when brand new and not letting heel get worn . Now I'm getting the wear out of the uppers . You need to shoot a little caulk in the can when brand new tube just like any caulk before using on shoe or your blacktop .

Excellent product. I've used the black color on asphalt cracks up to 3/8" and the gray color on concrete cracks. They both do an excellent job and hold up for years.

The Sikaflex - 410 is excellant for sealing between the asphalt drive and the concrete foundation wall to prevent water getting in behind and down the foundation. Only issue is the high price.

Does a great job better than most products I have used in the past

Has lasted over harsh winter and still fills the asphalts cracks.Will buy again

Good product overall, probably one of the best filler on the market. 30$ for 1 tube is crazy AF but the product is good quality. 5 stars if the price was around 20$ or less.

I was looking for a good pavement crack seller and fall on the 5 best crack seller for 2024 and the Soka was ranked number 1. Very nice product, simple to apply and auto nevelling, recommended !
