Begin sealing the rest of the asphalt by pouring a line of sealant along the width of your driveway. Those sealant buckets are heavy, so do your best not to spill excess.
Using the squeegee held at a 45-degree angle, pull and compress the sealant into the surface of the driveway. The sealant, like the crack filler, has self-leveling qualities, but work diligently and pay attention to how much pressure you’re putting on the squeegee to keep the layer of sealant as even as possible. If you’re pushing too hard, you’ll see sealant squeezing over the top of the squeegee. If you’re not pushing hard enough, your coverage will end up being too thick.
Work back and forth across the width of the driveway. Continue to pause periodically and use the paintbrush to manually paint in edges that meet structures for a finished look.
Allow the finished driveway to cure for 24 hours.
