Do You Need to Power Wash Before Sealcoating?

Sealcoating your parking lot is an essential step to prolong its lifespan and maintain a professional appearance. But before applying that protective seal, is power washing a necessary step? In this post, we'll explore the importance of power washing before sealcoating and how Capital Parking Lot Line Painting in Milton can help you achieve the best results.

Why Sealcoating Matters

Sealcoating acts as a protective barrier for asphalt surfaces, shielding them from the damaging effects of UV rays, oil spills, water penetration, and other environmental factors. For businesses and property owners in Milton, a top 30 city in Ontario, maintaining a pristine parking lot is crucial for safety and curb appeal.

The Role of Power Washing Before Sealcoating

Power washing is the process of using high-pressure water to clean the surface thoroughly. When preparing a parking lot for sealcoating, this step can make a significant difference in the final outcome.

Key Benefits of Power Washing Before Sealcoating

  • Removes Dirt and Debris: Dirt, dust, and loose particles can prevent the sealcoat from adhering properly.
  • Eliminates Oil and Grease Stains: Oil spots can repel sealcoat, leading to uneven application.
  • Prevents Mold and Mildew Growth: Moist and dirty surfaces promote mold which can degrade asphalt.
  • Improves Longevity: A clean surface ensures the sealcoat bonds well, extending the lifespan of your pavement.

Steps to Properly Prepare Your Parking Lot for Sealcoating

Capital Parking Lot Line Painting in Milton follows a detailed process to ensure quality results:

  1. Inspection: Evaluate the surface for cracks, potholes, and contamination.
  2. Power Washing: Thoroughly clean the asphalt with high-pressure water.
  3. Repairs: Fix cracks and holes to create a smooth surface.
  4. Drying Time: Allow the surface to dry completely before sealcoating.
  5. Sealcoat Application: Apply an even coat of sealant to protect the asphalt.

Common Mistakes to Avoid

  • Skipping Power Washing: Applying sealcoat on a dirty surface reduces adhesion and durability.
  • Sealing Wet Surfaces: Moisture trapped under the sealcoat can cause bubbling and peeling.
  • Ignoring Repairs: Sealcoating over cracks or potholes doesn’t fix underlying damage.
  • Using Low-Quality Sealcoat: Inferior products wear out faster and offer less protection.
