Sealcoating for asphalt surfaces is a vital process for extending the lifespan of roadway surfaces, such as home driveways, parking lots, and streets. This proactive care process consists of adding a protective coating to the asphalt surface, improving its lifespan and aesthetic value, while guarding it from surface degradation caused by weather, traffic, and spills.


 

The Process of Sealcoating

Sealcoating is the addition of a high-quality protective layer consisting of bitumen emulsion or coal tar pitch. This layer forms a strong surface that safeguards the asphalt from external agents, such as ultraviolet radiation, rainwater, oil, and chemicals. Over time, unsealed asphalt can show surface breaks, surface gaps, and degradation due to ageing and repeated traffic. Sealcoating helps prevent these issues by preserving the strength of the asphalt and lengthening its lifespan.
 

Key Reasons to Sealcoat

Shielding Asphalt from the Elements
Asphalt surfaces are frequently exposed to harsh weather, including precipitation, snow, and ultraviolet radiation. Stormwater can seep into cracks, triggering freeze-thaw cycles that weaken the surface. Sealcoating prevents moisture penetration and defends the asphalt from UV radiation, which can weaken it.

Keeping Asphalt Flexible
The aging process occurs when asphalt material is exposed to oxygen and sunlight. This process leads to the asphalt to turn brittle and form breaks. Sealcoating reduces the UV-related degradation, keeping the asphalt pliable and less likely to crack.

Making Asphalt Look New
A recently treated parking lot looks attractive and modern, upgrading the first impression of parking spaces, industrial areas, and business complexes. The sleek, black coating of sealcoating conceals flaws and provides a consistent appearance.

Saving on Repairs
Sealcoating is a relatively inexpensive way to safeguard parking areas relative to the large expenses of repairs or rebuilding. Periodic sealcoating can save property owners on future repairs eventually.

Shielding Against Harmful Substances
Driveways are often exposed to chemical spills, petroleum, and other chemicals that can compromise asphalt. Sealcoating forms a barrier that blocks these chemical hazards, preserving the asphalt and ensuring its longevity.
 

When to Reapply Sealcoating

Industry experts recommend performing sealcoating every biennially to triennially, based on vehicle loads and regional weather. Proper preparation, including thorough washing and sealing fissures, provides the sealcoating offers maximum protection.

In conclusion, asphalt sealcoating is an critical process for extending the life of the performance of asphalt surfaces. Regular sealcoating reduces repair costs, saves money over time, and improves the visual appeal of your property.
