Got cracks in your asphalt driveway? I filled mine with Sakrete Blacktop Crack Filler. Here’s how it went and what I’d do differently.
Sakrete Blacktop Crack Filler is a ready-to-use filler for asphalt and blacktop that dries to a black finish. It’s for fairly mild cracks, up to about an inch to an inch and a half wide. You squirt it into the crack and smooth it out. Here’s the prep, the application, and the tips I learned on my own driveway. Stock on Amazon was running low when I checked, so grab it while it’s there.
- Ready to use, no mixing
- Dries to a black finish
- One jug did quite a few cracks on my driveway
- Easy to spread with a putty knife
- Works on wider cracks up to about 1.5 in
- The nozzle is stored inside the jug, so it’s covered in filler
- Not self-leveling, so you have to spread it
- Starts to gel fast in the sun
- You may need more than one jug

Prep: clean your cracks
Clean out the cracks first. Scrub with a brush if you need to. I used a leaf blower to get the grass and debris out.
You’ll also want a spreader or putty knife, because it goes on a little thick and you have to smooth it out.
My first gripe: the nozzle
The nozzle is stored reversed inside the jug, so when you pull it out, it’s covered in filler. You have to clean it up and trim off the end, and it gets a little gross. Wear gloves. It would be nice if they attached it separately in a little bag.
Applying it
It comes out like a melting milkshake. It’s too thick to self-level, so you have to scrape it into the crack.
In direct sun it starts to dry and gel pretty quickly. When I did 30- or 40-foot strips, by the time I smoothed the last part, it was already getting a little plasticky or rubbery. Work in strips of no more than 10 or 20 feet: pour some down, then spread it with the putty knife.
Color and coverage
Going on, it’s a milk-chocolate brown, but you can see it turning black at the edges as it dries. Once you seal coat over it, that’ll add the black color and smooth it all out.
The jug did quite a few cracks on my driveway, including one that was an inch to an inch and a half wide in places and took quite a bit of filler. I still had maybe a fifth or sixth of the jug left. I actually ordered a couple of jugs, and depending on your driveway, more is better than less.
Curing and sealing
Let it cure. The label says about 5 days. After that, you can reseal your blacktop surface.
