Coverage rate varies by sealcoat product and surface texture. Rough or porous surfaces use more product. Always check your product's label for the recommended rate.
Sealcoating is a protective coating applied to asphalt surfaces every 2–3 years. It fills small surface cracks, restores a fresh black color, and dramatically extends the life of your driveway or parking lot by protecting against UV rays, water, oil, and fuel spills.
| Condition | Action |
|---|---|
| New asphalt (under 6 months) | Wait — too fresh |
| 6 months to 1 year old | Ideal first sealcoat |
| Every 2–3 years after | Routine maintenance |
| Heavily faded or cracked | Crack-fill first, then seal |
A quality sealcoat applied correctly lasts 2–4 years depending on traffic, climate, and UV exposure. In high-traffic or harsh-climate areas, recoating every 2 years keeps the surface in best condition.
Two coats is the standard recommendation. The first coat seals the surface and fills micro-pores; the second coat provides a uniform finish and extra protection. Apply the second coat after the first has dried fully (usually 24 hours).
Yes. DIY sealcoating is common for residential driveways. You will need a squeegee applicator or brush, sealcoat material from a hardware or building supply store, and good weather (above 50°F, no rain for 24 hours). Commercial lots with large areas are better handled by a paving contractor with spray equipment.
Coal tar sealcoat offers the best durability and is the professional standard for parking lots. Asphalt-based (bitumen) sealcoat is a popular DIY option and is more environmentally friendly. Acrylic sealers are used in areas where coal tar is restricted by local regulation. Check your local code before purchasing.
