Crack fillers come in many different types, each with their own pros and cons. Since we wanted to make sure that there would a product here perfectly suited to just about every need, we did our best to include a wide variety of options, from solid to completely liquid. This way, whether you have a short 1/2-inch crevice to fill or a large pothole to repair, there would be one here that makes the job easy.
Those who are searching for something to fill thin cracks in their driveway should look to Red Devil 0636 Blacktop And Roof, Roklin Systems Inc. Flomix, Sakrete Black Top Filler, Dalton Enterprises Pli-Stix 30-Foot, and Henry Company Elastomeric Emulsion. With the exception of Roklin Systems Inc. Flomix, Rust-Oleum EpoxyShield 250700, and Dalton Enterprises Pli-Stix 30-Foot, these all come ready to poured, or calked in in the case of Red Devil 0636 Blacktop And Roof, so there is no complicated mixing or physical stamping involved. Roklin Systems Inc. Flomix does require mixing, but all the components are premeasured, so there is essentially no chance of messing up. Plus, it offers the benefit of hardening in minutes, making it a good choice for high traffic areas where you don't have the luxury of keeping vehicles or people off the surface for days after application. Dalton Enterprises Pli-Stix 30-Foot comes as a pliable tube that you cut down to size and then melt into the crack with a torch.
If you are dealing with large potholes or cracks more than 1.5 inches wide, then you should turn to a solid variety, like EcoClean Solutions Patch And Pothole, Aquaphalt 6.0, and Road Rescue Patch. While these are nearly as easy to use as liquid options, they do require more physical effort, as you will have to tamp them down after dumping them in a hole. The benefit is that they can be applied in any weather and, in the case of Aquaphalt 6.0 and Road Rescue Patch, are ready for traffic immediately after application. Even with EcoClean Solutions Patch And Pothole you only have to wait one hour before it is traffic ready. Conversely, the liquid options generally take anywhere from 24 hours to five days to cure.

We did our best to include crack fillers that are known to last for a long time after application, so you aren't stuck dealing with the same problem just one or two years after use. We also thought it prudent to include dry and liquid options, as well as some that require heating and stamping.
