In the world of asphalt maintenance, sealcoating plays a major role in extending the lifespan of pavements, driveways, and parking lots for both commercial and residential properties. This article explores the scientific principles behind sealcoating, explaining how it acts as a shield against various damaging elements. Facility managers, building owners, and homeowners alike will find this information critical in preserving the integrity and appearance of their asphalt surfaces.

What is Sealcoating?

Sealcoating is a protective layer applied to asphalt-based pavements to shield them from the damaging effects of water, oils, UV rays, and other harmful substances. It is a preventive maintenance measure that can significantly extend the life of asphalt surfaces by providing a barrier that mitigates wear and tear.

The Composition of Sealcoating

Sealcoating products typically consist of a mixture of emulsified asphalt, mineral fillers, and various additives that enhance the coating’s performance. The exact composition may vary depending on the manufacturer and specific application requirements. These materials work in tandem to fill surface voids, providing a smooth, protective layer that resists penetration by water and chemicals.

How Sealcoating Protects Asphalt

Smoothing out commercial roads has a several major benefits. In fact, “smoother” roads can save up to 10% vehicle fuel compared to rough pavement.

Protection Against Water Damage

Water is one of the primary adversaries of asphalt, capable of causing extensive damage over time. When water penetrates asphalt, it can erode the base, leading to cracks, potholes, and eventual structural failure. Sealcoating acts as a waterproof barrier, preventing water from seeping into the asphalt and thereby reducing the risk of water-induced damage.

Resistance to UV Radiation

Ultraviolet (UV) radiation from the sun can significantly deteriorate asphalt surfaces, causing them to become dry, brittle, and susceptible to cracking. The sealcoating application includes UV-blocking components that help maintain the asphalt’s flexibility and prevent degradation caused by sun exposure.

Defense Against Oil and Chemical Spills

Asphalt surfaces are often subjected to oil and chemical spills, especially in commercial settings. These substances can penetrate the asphalt, weakening the bond between the aggregate and the binder, leading to surface breakdown. Sealcoating contains chemical-resistant materials that prevent these spills from damaging the asphalt.

The Application Process

Preparing the Surface

For sealcoating to be effective, the asphalt surface must be thoroughly cleaned and repaired. This includes removing debris, filling cracks, and addressing any potholes. Proper surface preparation makes sure the sealcoat adheres well and provides uniform protection.

Applying the Sealcoat

The sealcoat is typically applied using sprayers or squeegees, ensuring an even and comprehensive coverage. The number of coats and the specific application technique can vary based on the condition of the asphalt and the expected traffic load.

Curing Time

After application, the sealcoat requires time to cure before the surface can be used again. The curing process allows the sealcoat to harden and adhere properly to the asphalt, providing durable protection. The required curing time can vary depending on weather conditions and the specific sealcoating product used.
