Sikaflex-410 Asphalt Sealant, Black, Self-Leveling Hybrid Sealant for Filling Cracks in Asphalt Driveways, Roadways, and Pavements - 9 fl. oz. Cartridge, Fills Cracks up to 1.5 in. Wide

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.

Easy to use but the sealant sunk into the cracks so I had to buy another tube for a second application on top of the first. The second application is staying level with the driveway surface. Beware that if your cracks are deeper than a quarter inch you may need to fill them twice so will need more sealant than you think.

Love this product. It was very easy to use and did an amazing job at filling cracks in both the asphalt driveway and the edges where it meets concrete especially at garage door concrete pad seams. Highly recommend. Tip where I saw the old asphalt was beginning to wear and lift, the sealer was applied and then spread with cheap plastic scraper from the Dollar store. It worked like a charm. Saved so much money in using this product for repairs instead of paying a fortune to have a company do the repairs.

It lasted a bad winter this last season. Also a lot of cars turning over top of it. Impressive. So one year down and no complaints. One thing I have seen is the cracks where I applied liberally are holding their integrity better. It takes more but in my opinion and after using about 20 tubes now maybe a few more lost count but the more liberal the better results down the road. So don’t just try to squeeze enough to go inside the crack but enough to where it spreads out a pretty good amount over it. Can’t give exact amount but I cut the Tip pretty far down where more comes out in say a 1/4 inch thickness or something like that coming out. Poke the hole really good. If it’s hard to press you haven’t poked the hole good enough and it’s harder to run a consistent bead. I’ll update again on my second year.

This is a really great product. It typically sells in the $9-10 range but seems to go up in price more. For $9-10 I think is fair, $13 is a little excessive. This works very well though, it actually fills and spreads into the crack unlike other asphalt crack filler such as the stuff from Latexite that crack very easily. This takes a while to fully cure but it really is good quality and keeps it's shine months later in the summer heat. Absolutely amazing product!

Why did you pick this product vs others?: This stuff worked quite well. I'm not sure it "self leveled" quite the way I wanted, maybe the temperature needed to be warmer so the material was more fluid. Coming out of the tube, it was thicker and more viscous than I expected. This helped keep it where I wanted, but then I felt it didn't really "soak in" the way I thought it might. I've seen alternatives that require you "flame throw" a material and melt it into cracks: that seems like way too much trouble. Another aspect that was unexpected is that gaps or small sunken areas (likely from air trapped underneath) did appear later. I tried to go back and add more after the original had dried, but this appears to be a mistake. The material doesn't really bond to its dried self as it does to the asphalt. One thing I was able to accomplish by using this and doing it myself: I was able to completely seal ALL the craks on my driveway. This is unlike the driveway sealer guys who will spend 1 minute squirting their goop on your cracks before spending 4 minutes sealing the driveway. Now I feel the cracks are much better sealing from water getting in, and hopefully next winter I will have reduced or eliminated that freeze/thaw issue that gradually destroys the driveway.

Best crack filler I have ever used. Cracks opened slightly over a very harsh winter, but I will reapply when the weather warms.

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 !

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

this stuff is far superior and flexible compared to its competition, but the price is gross

SIKA is the gold standard when it comes to these sealants. Use a good, strong caulking gun. I used this sealant to fill the cracks in my asphalt, and leveled it smooth with a putty knife.
