Sealing a driveway protects it from water, UV, and freeze-thaw damage, extending its life and keeping it looking new. Asphalt and concrete have different products and timing, so match the sealer to your surface.
Clean and repair first
Sweep and pressure-wash the driveway, remove oil stains, and fill any cracks and let them cure. Sealer won't stick to a dirty surface or bridge open cracks, so prep is essential.
Pick the right weather
Seal on a dry, mild day with no rain in the forecast for at least 24 hours and moderate temperatures so the sealer cures properly. Avoid hot direct sun and cold.
Apply thin and even
Apply sealer in thin, even coats with a squeegee or applicator, working in sections toward an exit so you don't trap yourself. Thin coats cure better than thick ones. Keep traffic off until fully cured.
How often
Asphalt is typically resealed every 2–4 years; concrete sealers last longer. Don't overdo asphalt sealing — too-frequent or too-thick coats can crack and peel.
