Cold Crack Filler is a generic term for crack filling sealer that is typically used by DIY Home Owners or Small Businesses who need to maintain their own asphalt parking lot or driveway. There really aren't a lot of differences between our Cold or Hot crack filler when it comes to quality, they both do a great job. Where the Hot outshines the Cold, is it's "application to traffic" time being only around 40 minutes when compared to cold which can take several hours before traffic is allowed. The professionals use Hot Crack Filler mainly because they can do a job and move on quickly to the next, but it does require some pretty expensive equipment that a home owner or business owner won't really need. We also offer cold crack filling equipment if you prefer this method of filling cracks.
