1) Clean off all the dirt, grass or weeds which are in the driveway
If you have lots of grass or weeds growing within the cracks you may want to spray these with a weed and grass killer one or two weeks ahead of time which can make it easier to get them cleaned out. Make use of a trowel or putty knife to dig out as much of the dirt and debris as you possibly can from any cracks or holes. Make use of your lawn edger or a shovel or spade to go down the edges of the driveway and cut away any grass or dirt. Make sure you have clean edges along the entire length and that all dirt and debris is off from the cracks and holes. Then use your broom to sweep the driveway as clean as you possibly can.
2) Wash the driveway off thoroughly
If you have use of a pressure washer, this is an ideal method of cleaning the surface. Use it to clean the surface entirely and to blow out any dirt you can through the cracks and holes. If you use a garden hose, attach a nozzle to the end to give you the highest pressure possible. By doing a good job of cleaning now, you could save yourself a few years before you have to reseal again since you are doing an excellent job now.
3) Let the driveway dry entirely and check for contaminants
As it is drying watch for spots or areas that shine or appear dull from oil or other pollutants that have spilled on the driveway. Get a bucket of water and mix with a cleaner. Wash these spots off by scrubbing with your broom or a brush. You probably won't manage to get rid of the foreign material altogether, but the cleaner will help make a better surface for the sealing compound to stick. Rinse these areas off thoroughly after you finish cleaning them.
4) Fill any cracks or holes with Asphalt seal coating Filler
When the holes or cracks are deep, prep them by using sand to fill them nearly to the top. Then use your hose to wet these down completely to let them settle leaving them approx 1/2" thick. You may want to do this 2 or 3 times, waiting an hour or two in between each soaking. Allow the asphalt sealcoating to dry completely before using the crack filler. Apply the liner according to the directions on the container, but it is essential to make sure you get it genuinely into any cracks or holes and be sure you smooth the top to get a nice finished look. Wait for the filler to dry and reapply another coating if cracks reappear.
5) Apply the driveway asphalt sealer
Now that you've got all of the tricky preparatory work completed, this will likely seem like the natural part. The perfect situation would be to pick a warm, cloudy day. It will allow the sealer to flow on smoothly without drying too fast. Pour a moderate amount of blacktop sealer onto the driveway and spread it out evenly with your broom or foam mop. When you have a functional area done, pour out more and keep going. You should observe the directions on the container for the product you are using, but once you get started, you will get a feel for how much sealer you need to get a beautiful even coat. (If it has been many years since your driveway got a seal you may want to apply two blacktop repair coats.) Rope off the path to ensure nobody walks or drives onto it until it dries out.
