Sealcoating an asphalt driveway will protect it from oxidization, fuel spillage, cracks, and water damage — and your driveway will last you a lot longer if you sealcoat it, making sealcoating an essential protection of your investment. While you will be guaranteed a professional result if you hire professionals to sealcoat your driveway for you, many people also decide to go the DIY route and sealcoat their own asphalt driveways.
In this case, you should know that your sealcoat will need at least two layers to function optimally, and a curing time of at least 24 hours is essential before any vehicles return to the driveway. In hot weather, that curing period will take longer; 72 hours or even beyond.
It is important not to apply sealcoat if rain has been forecast in the next two days, and temperatures should be above 50 degrees as well.
Sealcoating your own driveway will not typically take you longer than a weekend, though waiting for it to cure definitely will. To save yourself from future headaches, familiarize yourself with the manufacturer’s instructions before you start sealcoating, and follow them carefully. Call in the professionals if you have any doubt about your ability to do the job successfully.
