Typically, a driveway is paved with asphalt. Subsequently, the surface is then secured with a top coat, or sealer. There are various application techniques for the sealer, including brushing and spraying.

Asphalt is a sticky substance made of various sands and gravels to form a flat, solid roadway. The sealer acts as the protector of the surface from cracks and the weather elements.
Contractors can seal asphalt by brushing or spraying the sealer on. By brushing it on, the thickness achieved may be uneven, resulting in a difficult cure over time and an overall slicker surface. On the other hand, spraying allows the sealer to be spread out in a uniform fashion, making it cure faster.
Inevitably, brushing the sealer on leaves brush marks and an unwanted appearance that is permanent. The only recommended time to use sealers with a brush is to fill in any tiny, spider cracks the asphalt exhibits.
