Sealing your asphalt driveway will add a protective layer over top of the existing asphalt and fill in the cracks. It's best to seal your driveway every three years or so to preserve the asphalt and prevent the cracks from spreading throughout the rest of the driveway. Here is a step-by-step guide to teach you how to seal an asphalt driveway properly.

1 – Start by cleaning the asphalt off with a hard bristled broom and clear away all the dirt and debris. It is important to make sure that there is no dirt or debris on the driveway when the sealant is applied as it can have a negative impact on the seal. Brush all the debris away and then dispose of it in a trash receptacle.

2 – Hook up a pressure washer to a water supply and then begin washing the driveway to get rid of any tough stains or dirt that is stuck to the asphalt. If you encounter a tough stain you can increase the water pressure and help to break the dirt down. Let the driveway dry for a full twenty-four hours to completely get rid of all the excess water that is on the driveway before you begin applying the sealant.

3 – Use paint rollers with a broom attached to the handle to apply the sealant to the driveway. Start at that front of the garage with the asphalt closest to the garage door and then slowly make your way towards the backside closest to the curb. Make sure that the sealant is applied evenly throughout the driveway and that there are not lumps of sealant stuck on the asphalt.

4 – When you finish applying the sealant, let it dry for a full twenty-four hours without driving or walking on the surface of the sealant.

5 – Repeat the process outlined in step three to add a second coat of sealant over top of the first coat. Let the second coat dry for another full twenty-four hours before you call the job complete.

If you follow the steps above and you still find that cracks or holes are developing in the asphalt, then you will require the help of an asphalt repair expert to help fix the problem. An asphalt expert will be able to come in and diagnose the existing asphalt to see if they can patch it or if the asphalt needs to be ripped out before fresh asphalt paving can be put in.
