Parking Lot Sealcoating
Parking lot sealcoating plays a crucial role in preserving the integrity and longevity of asphalt surfaces. As a protective barrier, sealcoating shields against the detrimental effects of weather, traffic, and various environmental factors.
This essential maintenance practice enhances the appearance of parking lots and extends their lifespan, saving property owners significant costs in the long run. Let’s learn more about the significance of parking lot sealcoating and its benefits for property owners and managers alike.
Parking Lot Sealcoating
Asphalt sealcoating is a protective layer applied to asphalt surfaces to guard against damage from natural elements and traffic. It involves applying a coal tar or asphalt-based emulsion, fortified with additives like sand and polymers, to create a durable barrier. This process fills surface voids and prevents water penetration, protecting against oxidation, UV rays, and oil spills. Driveway sealing enhances appearance while extending the lifespan of asphalt surfaces.

Pros and Cons of Sealcoating a Driveway
- Advantages of Sealcoating
Prevents water penetration below the surface, safeguarding against structural damage.
Slows down degradation caused by oxidation, preserving the asphalt’s integrity.
Shields the asphalt binder from oils and gasoline, reducing potential damage.
Improves skid resistance, enhancing safety for vehicles and pedestrians.
Boosts flexibility, allowing the pavement to withstand temperature fluctuations.
Facilitates simpler pavement maintenance, reducing the need for extensive repairs.
Prolongs the lifespan of pavement, saving on replacement costs in the long term.
Provides cost savings by preventing extensive damage and minimizing repair expenses.
- Disadvantages of Sealcoating
Initial costs can be relatively high, especially for larger areas.
Requires proper application by experienced professionals to be effective.
Can temporarily disrupt access to the coated area during application and drying.
Application may need to be repeated every few years for optimal protection.
Improper application or low-quality sealant may result in uneven coverage or reduced effectiveness.
Sealcoating may temporarily darken the appearance of the pavement.
Not suitable for severely damaged or deteriorated asphalt surfaces, which may require more extensive repairs.
Some sealants may contain chemicals that pose environmental concerns if not handled or disposed of properly.
When Is the Best Time of Year to Apply Parking Lot Sealcoat?
The best time for parking lot sealcoating is typically during the warmer, drier months like late spring and early summer. These conditions allow for proper drying and curing of the sealant. Additionally, scheduling during periods of low usage minimizes disruptions to parking lot traffic.
What Sealcoating Material Is Used?
Common materials used for sealcoating include:
1
Coal tar-based sealers
2
Asphalt-based sealers
3
Acrylic sealers
4
Emulsion sealers
5
Polymer-modified sealers
Each type of sealer has certain advantages and is suitable for different applications. Consulting with a professional contractor will help you determine the most appropriate material for your needs and budget.
How Long Should We Keep Vehicles off the Surface After Sealing?
After sealcoating, we usually recommend keeping vehicles off the surface for at least 24 to 48 hours to allow the sealant to properly cure and adhere to the asphalt. This helps prevent damage or tracking of the freshly applied sealant, ensuring optimal results and longevity.
What happens during the 48-hour drying period:
- Initial Curing: The sealant begins the curing process, where it begins to harden and adhere to the asphalt surface.
- Evaporation of Solvents: Solvents in the sealant start to evaporate, leaving behind a solid protective layer.
- Chemical Bonding: Chemical reactions occur between the sealant and the asphalt, forming strong bonds that enhance adhesion and durability.
- Surface Protection: The sealant creates a barrier that shields the asphalt from environmental elements such as UV rays, water, and chemicals.
- Strengthening: The sealant gradually strengthens, increasing its resistance to wear and tear from vehicular traffic and other stresses.
- Final Curing: Towards the end of the 48 hours, the sealant completes its curing process, achieving its maximum hardness and durability.
Why the waiting period is important:
- Prevents Damage: Keeping vehicles off the surface during the drying period prevents damage and ensures a smooth, uniform finish.
- Optimal Adhesion: Allowing sufficient drying time ensures the sealant properly adheres to the asphalt, maximizing its effectiveness in protecting the surface.
- Longevity of Coating: Proper drying and curing contribute to the sealant’s longevity, prolonging the lifespan of the asphalt surface and reducing the need for frequent reapplications.
- Maintains Appearance: Adequate drying time helps maintain the appearance of the sealcoated surface, preventing imperfections or blemishes that may occur from premature traffic.
