Residential & Commercial Sealcoating
1. Coverage & Thickness Control
Brooming forces the sealer down into the tiny voids, pores, and hairline cracks in the asphalt. This ensures a denser, more protective layer.
Spraying often lays a thinner coat on the surface. Unless multiple coats are applied, it can leave behind unsealed micro-pores that allow water, oil, and UV damage over time.
2. Bonding to the Asphalt
When you broom, you’re physically working the material into the asphalt. This helps it bond better and last longer, since adhesion is stronger.
Spraying mostly “mists” the surface. Without mechanical contact, adhesion relies solely on chemical stick, which can wear off faster under traffic.
3. Efficiency in Material Use
Brooming usually applies less waste and overspray, meaning more of the product ends up where it’s supposed to be.
Spraying can overspray onto grass, concrete, siding, or vehicles, wasting material and requiring extra cleanup.
4. Durability of the Finish
A broom-applied driveway generally lasts longer between reseals because the coating is thicker, more even, and well worked into the surface.
Sprayed applications may look uniform at first but tend to wear thinner under traffic faster.
5. Customer Perception
Many homeowners like to see the product being worked in — brooming looks like you’re really “sealing” their driveway.
A spray-only application can look fast and light, leading some customers to think it’s not as thorough.
6. When Spraying Makes Sense
Large commercial lots: spraying is faster and more cost-efficient, especially when paired with a broom/brush “cut-in” around edges.
Topcoat finish: some contractors broom the first coat (for bond and penetration) and spray a second coat (for uniform, clean appearance).
