Sealcoating an asphalt driveway allows you to protect the surface from damage and prolong its lifespan. While a simple process, it is important that you know how to prepare the driveway and apply the driveway sealant. Here are some easy rules to follow for sealcoating your asphalt driveway.
Repair Surface Damage First
The first thing you should do when you want to seal a driveway is to repair any damage you find. Inspect the entire surface thoroughly and take note of any cracks, holes, or other damage you find. Cracks can be filled with an asphalt filler product, which is easy to apply, but does take a small amount of preparation work. Clean out the cracks to remove dirt and debris by removing the debris by hand or using a pressure washer to force it out. Be careful not to create larger cracks when cleaning them out. If you used the washer, wait for it to dry, then fill the cracks with the filling product, following the manufacturer's instructions. Let it dry fully before continuing.
Clean the Driveway Thoroughly
Once the cracks have been filled and the filling product is dry, you can clean the rest of the driveway. A good way to start is by checking the perimeter of the driveway and pulling any weeds or grass that is laying over the driveway. This is going to get in the way of the sealing process, so it must be trimmed. Once that is done, remove any grease or oil stains on the driveway. Soapy water is usually enough to clean most driveway stains. Rinse it with a pressure washer or regular garden hose with a pressure nozzle attached. Once again, let the driveway dry completely before you apply sealant.
Seal on the Right Day
You also need to choose the right day for sealcoating the driveway. Look at the forecast and choose a day where rain and snow is not expected for at least a few days. You also don't want extreme heat, as that can cause the sealant to dry prematurely and give you an uneven surface. Try to do the sealcoating on a cloudy or overcast day. Avoid doing it in the middle of the day, as that is when the sun is at its highest and it tends to get hot. Late mornings and early afternoons are often ideal.
Work in Smaller Sections
When you are ready to apply the sealant, pre-mix the container by turning it upside down and leaving it that way for several minutes. Then flip it back over and remove the lid. This should begin the mixing process, but you also want to stir the contents after removing the lid. When you apply it, use smaller sections, starting at one corner of the driveway and coating a small, manageable section at a time. This is typically better than going in rows or strips. Use thin layers, overlapping them slightly so you don't miss any spots. Make sure after applying it, you let it dry for a few days before driving on the asphalt.
