How Sealcoating Protects Against Salt and De-Icing Chemicals

Winter in Kingston can be harsh, and the use of salt and de-icing chemicals is essential to keep roads and parking lots safe. However, these substances can cause significant damage to asphalt surfaces. Discover how sealcoating offers vital protection, prolonging the life of your pavement.

Understanding the Impact of Salt and De-Icing Chemicals

Salt and other de-icing chemicals are crucial during the winter months in Kingston, a top 30 city in Ontario, known for its snowy winters. While they effectively melt ice and snow, these substances accelerate the deterioration of asphalt. Salt penetrates cracks and weakens the binder that holds asphalt together, leading to potholes, cracking, and surface erosion.

The Chemistry Behind the Damage

When salt dissolves, it creates a corrosive solution that seeps into the pores of asphalt. It reacts with water and the asphalt binder, stripping away essential oils and causing the surface to lose flexibility. This process speeds up oxidation and cracking, especially under freeze-thaw cycles common in Kingston’s winter climate.

What is Sealcoating?

Sealcoating is a protective layer applied to asphalt surfaces to guard against environmental damage. It typically consists of a mixture of refined tar, oil, water, and additives that form a durable barrier. By applying sealcoat, parking lots and driveways become less permeable to water, salts, oils, and UV rays.

Why Sealcoating is Essential in Kingston

For property owners in Kingston, where winter conditions subject parking lots to frequent salt application, sealcoating is a critical maintenance step. It not only protects the asphalt but also enhances its appearance and safety by improving surface texture.

Benefits of Sealcoating Against Salt and De-Icing Chemicals

  • Prevents Salt Penetration: Sealcoating forms a waterproof barrier that stops salt from seeping into the asphalt.
  • Reduces Oxidation: The sealcoat layer protects asphalt from oxygen exposure, slowing down the hardening and cracking process.
  • Extends Pavement Life: By protecting against chemical damage, sealcoating helps to maintain structural integrity longer.
  • Improves Appearance: A fresh sealcoat restores the deep black color of asphalt, making your parking lot look well-maintained.
  • Cost-Effective Maintenance: Sealcoating reduces the frequency of costly repairs and resurfacing.

Step-by-Step Sealcoating Procedure

  • Surface Cleaning: Removal of dirt, debris, and old coatings to prepare the asphalt.
  • Crack Filling: Sealing cracks to prevent water and salt intrusion beneath the surface.

Common Mistakes to Avoid When Sealcoating

  • Applying sealcoat over wet or cold surfaces, leading to poor adhesion.
  • Skipping crack repairs, which allows salt to penetrate and cause damage beneath the surface.
  • Using low-quality sealcoating products that don’t provide adequate protection.
  • Ignoring regular maintenance schedules, especially in regions like Kingston with severe winters.
  • Not allowing sufficient curing time before reopening the parking lot to traffic.
