Maintaining asphalt surfaces is very important to preserving their durability, functionality, and appearance. Two common methods of asphalt maintenance are sealcoating and crack filling, but many property owners and managers often confuse these processes. While both are vital for extending the life of your asphalt, they serve different purposes and address different issues. Andersen Asphalt & Striping would like to break down the key differences to help you make a proper decision about your asphalt maintenance needs.
What is Asphalt Sealcoating?
Sealcoating is a protective layer applied to the entire surface of the asphalt. It acts as a barrier against damaging elements such as:
• UV rays: Prolonged exposure can weaken and dry out asphalt, leading to cracks.
• Water: Sealcoating prevents water from seeping into the surface, where it can freeze and cause damage.
• Oil and chemicals: Fluid drips from vehicles can erode unprotected asphalt over time.
Sealcoating is primarily preventative and works best when applied to asphalt that is still in relatively good condition. It restores the rich, black appearance of the asphalt, improves its resistance to wear and tear, and extends its lifespan.
What is Crack Filling?
Crack filling is a targeted repair method used to address specific cracks in asphalt surfaces. Over time, asphalt naturally develops cracks due to factors such as:
• Temperature fluctuations: Expansion and contraction during freeze-thaw cycles.
• Heavy traffic: Constant weight and movement can stress the surface.
• Aging: Asphalt loses flexibility as it ages, making it more prone to cracking.
Crack filling involves cleaning the cracks and filling them with a flexible material, such as rubberized asphalt or polymer-modified fillers. This prevents water and debris from infiltrating the cracks and causing further damage.
Can Sealcoating & Crack Filling Be Combined?
Yes! In fact, combining the two processes is the best approach for proper asphalt maintenance. Crack filling should be done first to address structural issues, followed by sealcoating to provide a uniform protective layer. This combination ensures a smoother surface, enhances durability, and prevents future damage.
Why Is It Important to Differentiate Between Sealcoating & Crack Filling?
Understanding the difference between sealcoating and crack filling allows you to take the right steps for your asphalt’s specific needs. Neglecting cracks without filling them first can render sealcoating ineffective, as water can still penetrate the surface through untreated cracks. Applying crack filling without following up with sealcoating leaves the surface unprotected from external elements. Both sealcoating and crack filling are essential components of asphalt maintenance, but they address different problems and serve unique purposes. If your asphalt shows signs of wear or cracking, consulting with a professional can help you determine the right combination of services to preserve its longevity and appearance.
