Asphalt Driveway Sealing: Benefits, Limitations, and Realistic Expectations

Sealcoating slows oxidation and water penetration, extending pavement life by 2–4 years per application. It does not stop cracking from freeze-thaw cycles or heavy loads. Apply every 3–5 years. Best done in warm, dry weather (50–85°F). It's a maintenance tool, not a permanent fix. Budget for periodic resealing and crack filling.
