How to Know If Your Asphalt Surface Is Ready for Sealcoating

Sealcoating your asphalt surface is an essential step in extending its lifespan and maintaining its appearance. But how can you tell if your asphalt is ready for this important maintenance? In this guide, we'll explore the key signs and conditions to look for before scheduling sealcoating, especially for property owners in Oakville.

Asphalt Sealcoating

Why Sealcoating Matters for Oakville Asphalt Surfaces

Oakville, one of Ontario's top 30 cities, experiences a variety of weather conditions that can affect asphalt surfaces. From winter freezing to summer heat, asphalt is susceptible to damage such as cracking, fading, and erosion. Sealcoating acts as a protective barrier, preventing water infiltration, oil spills, and UV damage.

Capital Parking Lot Line Painting often recommends sealcoating as a key preventative maintenance step to keep parking lots and driveways in top condition, ensuring safety and curb appeal.

Key Signs Your Asphalt Surface Is Ready for Sealcoating

1. Visible Surface Cracks and Fading

Before sealcoating, check for hairline cracks, surface wear, or fading color. Minor cracks can be sealed before applying the coat, but large cracks or potholes should be repaired first for the best results.

2. Absence of Moisture

Sealcoating should only be done on dry asphalt. Moisture interferes with the adhesion of the sealant and can cause bubbling or peeling. Make sure the surface has been dry for at least 24-48 hours after rain or snow melt.

3. Clean Surface Free of Debris

A clean surface is critical. Remove dirt, leaves, oil spots, and old sealcoat flakes to ensure the new coat properly bonds to the asphalt.

4. Temperature and Weather Conditions

Sealcoating requires temperatures above 10°C (50°F) and dry weather for at least 24 hours after application. Avoid scheduling sealcoating during rainy or extremely hot days.

Steps to Prepare Your Asphalt for Sealcoating

  • Inspect and Repair: Address cracks and potholes with professional repairs.
  • Clean Thoroughly: Power wash the surface to remove all dirt and debris.
  • Dry the Surface: Allow sufficient drying time after cleaning or rain.
  • Choose the Right Time: Schedule sealcoating during favorable weather.

Common Mistakes to Avoid Before Sealcoating

  • Sealing over wet or damp asphalt
  • Ignoring cracks and damage repairs
  • Applying sealcoat in extreme temperatures
  • Failing to clean oil and grease stains
