This video is a step-by-step tutorial about how to fill in an asphalt driveway crack. There are three items you are going to need to do the job. A tube of water-proof asphalt crack filler, a caulking gun, and an old concrete trough.
Before filling in the crack you should hose down the area and use a leaf blower to clean out and dry the crack prior to filling.
First, use the tool on the caulking gun to cut the tip off the tube. Next, place the tube inside the caulking gun and make sure it fits snugly.
Now you are going to run a nice bead of asphalt filler along the entire crack in your driveway. Ease of the lever of the caulking gun as you approach the end of the crack.
Take your concrete trough and smooth out the asphalt filler. Take the asphalt filler again and run an additional bead across the top. Use your trough to smooth that out once again.
It takes approximately 24 hours to seal. Ensure not to fill the cracks if you have rain in the forecast. Also, you should avoid driving on it for the next day.
