How Sealcoating Protects Against Salt and De-Icing Chemicals
In regions like Newmarket, where winter months bring heavy snow and the frequent use of salt and de-icing chemicals, protecting your pavement is essential. Sealcoating offers an effective barrier that extends the lifespan of asphalt surfaces, maintaining their structural integrity and appearance.

Understanding the Effects of Salt and De-Icing Chemicals on Asphalt
Salt and other de-icing agents are necessary for keeping roads, driveways, and parking lots safe during icy conditions. However, these chemicals can be harsh on asphalt surfaces. Over time, they penetrate the pavement, accelerating deterioration by breaking down the binding agents that hold the asphalt together.
In Newmarket, a city known for its cold winters, this issue is particularly relevant. The repeated freeze-thaw cycles combined with chemical exposure often lead to cracks, potholes, and surface wear.
What Is Sealcoating and How Does It Work?
Sealcoating is the application of a protective liquid layer over asphalt surfaces. This layer acts as a shield, preventing water, salt, oils, and UV rays from penetrating and damaging the pavement beneath.
Key Functions of Sealcoating:
- Blocks moisture from seeping into the asphalt
- Protects against oxidation caused by sunlight
- Reduces damage from salt and de-icing chemicals
- Enhances the surface’s appearance with a fresh black finish
- Extends the overall lifespan of the pavement
