What Is Seal Coating?
Seal coating is the application of a protective liquid coating over asphalt pavements. This specially formulated sealant acts as a barrier, shielding the surface from harsh elements such as sunlight, water, oils, and chemicals that cause cracking, fading, and deterioration. Seal coating restores the rich black finish of asphalt, improves its overall appearance, and enhances its resistance to wear and tear.
Why Should You Seal Your Driveway?
Applying a quality seal coat to your asphalt driveway or pavement provides several important benefits:
Protects Against Weather Damage: Seal coating prevents water from penetrating the pavement and causing cracks or potholes and protects against the damaging effects of UV rays that cause asphalt to become brittle.
Extends Pavement Lifespan: Regular seal coating can significantly extend the life of your asphalt by preventing damage that leads to costly repairs or costly premature replacement.
Improves Curb Appeal: A fresh seal coat restores the deep black color of your driveway or parking lot, greatly enhancing the appearance and increasing property value.
Resists Oil & Chemical Stains: Seal coating creates a protective layer that resists damage from auto fluids, gasoline, and other chemicals that can degrade asphalt surfaces.
Cost-Effective Maintenance: Compared to resurfacing or repaving, seal coating is an affordable way to maintain the health and beauty of your asphalt.
Homeowners and commercial property owners alike can benefit from scheduling routine seal coating to keep their asphalt surfaces in excellent condition year after year.
Our Seal Coating Process
At SJ Asphalt Paving, we follow a detailed, professional seal coating process to ensure lasting results:
- Surface Cleaning: We begin by thoroughly cleaning the asphalt surface to remove dirt, debris, loose aggregate, oil spots, and other contaminants that could affect sealant adhesion.
- Crack & Repair Work: Before sealing, we inspect the pavement for cracks, holes, or damage. Our experienced team completes any necessary patchwork or repairs to create a smooth, sound base.
- Edge Preparation: We carefully prepare edges and adjoining surfaces to prevent sealant from spilling onto unwanted areas such as grass, concrete, or landscaping.
- Sealant Application: Using high-quality seal coating products and professional equipment, we evenly apply the protective coat over the prepared asphalt surface.
- Curing & Drying: After application, the seal coating needs time to cure. Customers should avoid driving or placing heavy objects on the surface for at least 24-48 hours, depending on weather conditions.
- Final Inspection: Once dry, our team performs a final inspection to ensure a uniform coat and address any touch-ups needed.
Frequently Asked Seal Coating Questions
How often should I have my asphalt seal coated?
We recommend seal coating every 2 to 3 years to maintain optimal protection and appearance, though the frequency may vary depending on traffic, weather, and overall pavement condition.
What is the best time of year to apply seal coating?
Seal coating is best applied during warm, dry weather, typically in late spring through early fall, when temperatures are consistently above 50°F to ensure proper curing.
How long does seal coating take to dry?
Seal coating usually requires 24 to 48 hours to dry and cure fully. Avoid driving or parking on the surface during this time to achieve the best results.

Seal coating is designed to protect and preserve asphalt surfaces but does not repair structural issues. Any cracks or potholes should be repaired before seal coating is applied.

No, seal coating can be applied to a variety of asphalt surfaces, including parking lots, private roads, pathways, and other commercial or residential pavements.
Can seal coating prevent damage from oil spills?
Yes, seal coating provides a protective layer that helps resist damage from oil, gasoline, and other chemicals, extending the life of your asphalt.
