How Sealcoating Protects Against Salt and De-Icing Chemicals

Sealcoating is an essential maintenance step for asphalt surfaces, especially in cities like Oshawa where harsh winter conditions and the widespread use of salt and de-icing chemicals can cause significant damage. In this article, we explore how sealcoating acts as a protective barrier, extending the life of your parking lot or driveway.

What Is Sealcoating?

Sealcoating is a protective layer applied to asphalt surfaces that seals tiny cracks and pores. This process prevents water, oils, and chemicals from penetrating the asphalt, which can lead to deterioration. By creating a barrier, sealcoating helps maintain the structural integrity and appearance of your pavement.

Why Salt and De-Icing Chemicals Are Harmful

During winter months, municipalities and property owners in Oshawa frequently use salt and other de-icing chemicals to keep roads and parking lots safe. While effective at melting ice, these substances can cause serious damage to asphalt by:

  • Accelerating the breakdown of asphalt binder and aggregates
  • Increasing the risk of cracks and potholes
  • Encouraging water penetration that leads to freeze-thaw damage
  • Causing discoloration and surface wear

How Sealcoating Protects Asphalt Surfaces

Sealcoating forms a waterproof and chemical-resistant layer that shields asphalt from the harmful effects of salt and other de-icing agents. Here’s how it works:

1. Creates a Water-Resistant Barrier

By sealing the porous surface of asphalt, sealcoating prevents water mixed with salt from seeping into the pavement. This reduces the risk of freeze-thaw cycles that cause cracks.

2. Shields Against Chemical Penetration

Salt and de-icing chemicals can weaken the asphalt binder, making the surface brittle and prone to damage. Sealcoating blocks these chemicals from reaching the underlying layers, preserving the pavement’s flexibility and strength.

3. Enhances Surface Durability

With regular sealcoating, asphalt surfaces maintain their integrity longer, resisting the wear and tear caused by winter treatments.
