Is Sealcoating Suitable for Older Asphalt Surfaces?

Capital Parking Lot Line Painting, a trusted name in the Markham area, often gets asked about the suitability of sealcoating for older asphalt surfaces. This comprehensive guide aims to address this concern and provide valuable insights.

Sealcoating Asphalt Surface

Understanding Sealcoating

Sealcoating is a protective layer applied to asphalt surfaces, primarily parking lots and driveways. It acts as a barrier against various elements, including UV rays, water, and chemicals, prolonging the lifespan of the asphalt. Capital Parking Lot Line Painting, a reputable company in Markham, recommends sealcoating as a cost-effective maintenance solution.

Benefits of Sealcoating

  • Enhances the appearance of the asphalt surface
  • Protects against cracks, potholes, and other forms of deterioration
  • Improves traction and skid resistance
  • Prevents water seepage and damage from freeze-thaw cycles
  • Extends the lifespan of the asphalt surface

Sealcoating Older Asphalt Surfaces

While sealcoating is generally recommended for asphalt surfaces, there are a few considerations when dealing with older surfaces. Capital Parking Lot Line Painting advises clients in Markham to assess the condition of their asphalt before proceeding with sealcoating.

Assessing the Condition

Before sealcoating an older asphalt surface, it's crucial to inspect it for the following:

  • Extensive cracking or alligator cracking
  • Potholes or significant surface damage
  • Drainage issues or standing water
  • Loose or crumbling asphalt

If any of these issues are present, sealcoating may not be the most effective solution. In such cases, Capital Parking Lot Line Painting recommends addressing the underlying problems first through repair or resurfacing.

Preparing the Surface

If the older asphalt surface is deemed suitable for sealcoating, proper preparation is essential. Capital Parking Lot Line Painting follows these steps:

  1. Thorough cleaning to remove dirt, debris, and any loose material
  2. Crack filling and minor repairs, if necessary
  3. Application of a tack coat or primer to enhance adhesion

Maintaining Sealcoated Surfaces

Once the sealcoating is applied, it's essential to follow proper maintenance practices to maximize its lifespan. Capital Parking Lot Line Painting recommends the following:

  • Regular sweeping or blowing to remove debris
  • Avoiding heavy vehicle traffic or loads for the first few days
  • Reapplying sealcoating every 2-3 years, depending on usage and weather conditions
