Is Sealcoating Suitable for Older Asphalt Surfaces?
Sealcoating is a popular maintenance solution to extend the life of asphalt surfaces. But when it comes to older asphalt, many property owners in Oshawa wonder if sealcoating is still effective or even advisable. In this article, we explore the suitability of sealcoating for aging asphalt and share expert insights from Capital Parking Lot Line Painting.
Understanding Sealcoating and Its Purpose
Sealcoating involves applying a protective coating over asphalt surfaces to shield them from damaging elements like UV rays, water penetration, oil spills, and oxidation. This process not only improves the appearance but also helps prevent cracks and potholes from developing prematurely.
What Does Sealcoating Do?
- Protects against sun damage and oxidation
- Seals minor cracks and surface imperfections
- Prevents water infiltration that can weaken the base
- Enhances curb appeal with a fresh, black finish
- Makes subsequent maintenance like line painting more effective
Can Older Asphalt Be Sealcoated?
When asphalt ages, it undergoes natural wear and tear, including cracking, surface erosion, and loss of oils that keep it flexible. While sealcoating is excellent for newer or moderately aged asphalt, its effectiveness on older surfaces depends on the current condition.
Capital Parking Lot Line Painting, a leading service provider in Oshawa, emphasizes that sealcoating is suitable for older asphalt only if the surface is structurally sound. This means:
- Minimal or no major cracking
- Stable base with no significant potholes or depressions
- Surface free of debris, oil stains, and vegetation growth
If these conditions aren't met, sealcoating might trap moisture or worsen surface deterioration instead of protecting it.
Signs That Older Asphalt May Not Be Ready for Sealcoating
- Large, interconnected cracks (alligator cracking)
- Extensive potholes or crumbling edges
- Severe surface raveling or loose aggregate
- Standing water or drainage issues
Preparing Older Asphalt for Sealcoating
If the asphalt is aging but salvageable, proper preparation can make sealcoating successful. Capital Parking Lot Line Painting advises Oshawa property managers to follow these key steps:
- Thorough Cleaning: Remove all dirt, debris, and stains using power washing or sweeping.
- Crack Sealing: Fill and seal cracks to prevent water infiltration.
- Pothole Repairs: Patch any holes or depressions to create a smooth surface.
- Drying Time: Ensure the asphalt is completely dry before applying sealcoat.
Benefits of Sealcoating Older Asphalt When Done Correctly
When older asphalt is properly assessed and prepared, sealcoating offers several advantages, including:
- Extending the life of the pavement by slowing oxidation
- Improving surface texture and appearance
- Providing a better base for line painting and other markings
- Reducing maintenance needs in the short term
