Is Sealcoating Suitable for Older Asphalt Surfaces?
Sealcoating is a popular maintenance method for asphalt pavements, but is it the right choice for older surfaces? In this post, we’ll explore the benefits, limitations, and best practices for sealcoating older asphalt, with insights from Capital Parking Lot Line Painting, a trusted service provider in Cambridge, Ontario.
Understanding Sealcoating and Its Purpose
Sealcoating is the process of applying a protective layer over asphalt surfaces to shield them from environmental damage, UV rays, oil spills, and water infiltration. This protective coating extends the life of the pavement by preventing oxidation and cracking.
Challenges of Sealcoating Older Asphalt
Older asphalt surfaces present unique challenges that can affect the effectiveness of sealcoating. Over time, asphalt deteriorates through weather exposure, traffic wear, and natural aging, resulting in cracks, potholes, and surface irregularities.
Common Issues with Older Asphalt:
- Surface Cracking and Alligatoring
- Oxidized and Brittle Pavement
- Existing Potholes and Depressions
- Loss of Aggregate Bond
Is Sealcoating Recommended for Older Pavements?
Sealcoating older asphalt is not always straightforward. While it can provide a refreshed look and added protection, it is crucial that the surface is in a condition that can properly bond with the sealcoat. According to experts at Capital Parking Lot Line Painting in Cambridge, applying sealcoat to severely damaged or heavily cracked asphalt is often ineffective and may even accelerate failure if underlying issues are not addressed first.
When Sealcoating Older Asphalt Makes Sense:
- The surface has minor cracks that can be sealed
- There is no significant structural damage or deep potholes
- The asphalt has not been extensively oxidized or eroded
In these cases, sealcoating can restore the appearance and extend the pavement’s life by several years. However, proper surface preparation, including crack filling and patching, is essential to ensure a successful application.
Steps to Prepare Older Asphalt for Sealcoating
Capital Parking Lot Line Painting recommends a thorough preparation process to maximize sealcoat adhesion and durability, especially in Cambridge’s varied climate:
- Cleaning: Remove dirt, debris, and vegetation to provide a clean surface.
- Crack Repair: Fill cracks with appropriate sealants to prevent water infiltration.
- Patching: Address potholes and significant surface damage with patching materials.
- Drying: Ensure the pavement is completely dry before applying the sealcoat.
