If it is truly a heavy-bodied sealcoat rather than a mostly-water pretty surfacing, brushing will work the material down into the voids in the driveway better, with better waterproofing and adhesion being the result. Spraying, and just squeeging without brushing in first, leaves a lot of buried voids and does not give at complete an adhesion. Spraying to get the material on, then brushing and squeeging to work it in is fine too, if it comes to the jobsite in a tank rather than pails.

A lot of contractors use spray equipment because it goes on a lot faster and with less labor, plus tends to be a thinner coat so is cheaper to do. This does not make it better for the homeowner.

With hot-applied (250-400 degree) true asphalt resurfacing, spraying is fine because it is so hot it flows into all the voids before it sets, and because it is actually asphalt, it "wicks" to adhere to the underlying pacing.

Brush if you are building texture. Spray if your rolled tight.
