When and why to seal
Seal every 2-3 years, or when the asphalt looks gray and porous. Sealing prevents water from freezing and expanding inside the asphalt, which is what causes potholes and cracks.
Prep determines the result
Power washing, crack filling and dry weather are essential. Sealant applied over dirt or moisture peels within months. Plan two coats for even coverage and 12-24 hours of drying.
