Home Improvement/How To Repair Asphalt Driveway Cracks

Oh, hey! How are you doing? I’m just bringing out the last tool to start my blacktop crack repair job. Great weather today, blacktop’s dry, and that’s exactly what you need when you get ready to finish a blacktop repair job. Here’s what we’ve got. First thing we need to do before we get started, in case the safety police are watching, it’s time to get on the new, cool safety glasses. Oh, yeah – what do you think about that?

Now, what we gotta do – first thing that it says on the instructions on the caulk, or the repair sealant that we’re gonna use – you gotta clean out the crack. I always like to use a regular broom, and it works really well! Just go ahead and sweep it out, get all of that loose debris and loose sand out of the way…oh, yeah! Simple as that! Now, once again, remember the blacktop’s gotta be nice and dry.

So, let me show you what I’ve got, what we’re gonna use today. We’ve got this nice crack. And, this particular crack is kind of like a V shape. And, because it’s V shaped, it’s really pretty hard to install a backer rod, that sometimes you have to use when you install a crack sealant with blacktop. Usually, you use a backer rod when the crack is shaped more like this, where the sides of the crack are pretty parallel. And, you’ll get those cracks very frequently in a blacktop driveway, but not this particular one.

So, what we’re gonna do first is, all you have to do is start with this compound. It’s an asphalt repair – check this out, it says right here – Asphalt Repair, it’s got all the nice instructions, and it looks – it’s just like, really, caulking. And simple! All you do is go ahead and start to squeeze it out, being really careful that you don’t put too much of the material too high, because you will have a real mess on your hands. And you can see how easy that comes out! It just flows out of the tube, and one of the reasons that it flows really well is because I made sure that it wasn’t too cold out here. The outside temperature here is about 60 – 65°, and this material flows just beautifully out of this tube, and you can see that.

Now, check this out – get a little closer, I want to show you something. I’m coming up to a really big, wide area, and I want to fill that up, but not too high, and you’ll see in a minute why. And there’s another one coming up right next to it. Oh, yeah, look at this right here, you can see a big area. I kind of put the sealant in there, making sure it’s not too high.

Alright, now, here’s what I wanna show you. The next step is, I’ve got this cute, little stick – it’s actually from a piece of mulch…check this out. You can see it’s about ¼ inch wide, and I found it in the mulch, actually right next to the blacktop drive. And I just use that. Come down here close, I wanna show you something. I actually want to spread this sealant so that it smears on the blacktop on either side of the caulk, and I’m also making sure that the caulk sealant is not too high. And this makes for a really, really good bond, so that the crack sealant material will not come out, you know, this winter, when it gets really, really cold.

Now, but down here, where it’s really, really wide…before I started the job, I went around and I found some of the rocks that had actually come out of the blacktop drive. What you do is you actually put these rocks right in the sealant compound. I know it sounds crazy, but this actually helps – it helps disguise the crack, for one. And it helps make the crack sealant work a lot better, because it makes it stronger. And you just push those rocks down into the sealant, and then you push the material up against it, so that the cracks – and so that the cracks fill up with material, and it sticks well against these little rocks.

The final step in the process is to actually take some of this magic compound that I have in this can next to me…ho hooo…wait til you see this trick! A lot of people don’t do this. This is one of the secret “Ask The Builder” tricks! Before I started the job, I went to the sides of the driveway, and I found some sand. And some of this sand came from the stones and the rocks around the driveway, but actually matches perfectly, some of the rocks that are actually in the blacktop. And you go ahead and just sprinkle this sand onto the fresh compound. Look at that. Simple as that! And this sand does 2 things:

#1 – It will prevent tracking, if someone makes a mistake and walks on this material, and from it spreading onto the driveway, it does that. And that’s really important.

#2 – It’s actually gonna help disguise this crack, so that the crack looks more like the actual blacktop, on either side of the crack.

It’s that simple to patch a blacktop crack! I’m Tim Carter for AskTheBuilder.com –
