Sealcoating is the process of applying a protective layer (sealant) over asphalt pavement to enhance its durability, appearance, and longevity. This protective coating helps shield the surface from the damaging effects of weather, chemicals, oil spills, and general wear and tear.
Why Sealcoat is Important:
Protects Against UV Damage
The sun's ultraviolet rays can cause asphalt to oxidize and break down over time, leading to cracks and fading. Sealcoating helps prevent UV damage by creating a protective barrier.
Prevents Water Damage
Water is one of the primary causes of pavement deterioration. Sealcoating helps keep water from penetrating into the asphalt, reducing the risk of cracks and potholes caused by freezing and thawing cycles.
Protects Against Oil and Gas Spills
Oil and gas can quickly degrade asphalt, leading to soft spots and cracks. Sealcoating provides a layer of protection, helping the surface resist the damaging effects of spills.
Enhances Aesthetic Appeal
Sealcoating restores the dark, rich appearance of the asphalt, giving it a like-new look. It can also help mask minor imperfections, making the surface look smoother and more uniform.
Increases Lifespan
By protecting the pavement from various elements and preventing premature damage, sealcoating can significantly extend the lifespan of asphalt surfaces, saving money on expensive repairs or repaving.
Timing: Sealcoating is typically applied every 2-3 years, depending on traffic, weather conditions, and the level of wear the pavement experiences.
