Do You Need to Power Wash Before Sealcoating?

Sealcoating your asphalt parking lot is an essential step to protect it from wear and tear, but is power washing a necessary part of the process? In this article, we explore why cleaning your surface before sealcoating matters, especially for property owners in Barrie looking for quality results.

Why Sealcoating Matters

Sealcoating is a protective layer applied to asphalt surfaces to extend their lifespan and improve appearance. It protects against UV damage, water infiltration, oil spills, and other environmental factors. For residents and businesses in Barrie, a city known for its changing weather and seasonal variations, sealcoating is especially beneficial in maintaining parking lots and driveways in top condition.

Capital Parking Lot Line Painting, a trusted company in Barrie, consistently emphasizes the importance of proper surface preparation before sealcoating to ensure the best results.

The Role of Power Washing Before Sealcoating

What is Power Washing?

Power washing uses a high-pressure water spray to remove dirt, grime, oil stains, loose paint, and other debris from surfaces. When preparing for sealcoating, the goal is to create a clean, debris-free surface so the sealcoat adheres properly and lasts longer.

Benefits of Power Washing Before Sealcoating

  • Improved adhesion: Removing contaminants allows the sealcoat to bond effectively with the asphalt.
  • Enhanced appearance: Clean surfaces result in a smoother, more uniform finish.
  • Extended lifespan: Proper prep helps prevent peeling and cracking of the sealcoat.
  • Preventing costly repairs: Dirt and debris can trap moisture, leading to premature asphalt damage.

Steps to Prepare Your Asphalt for Sealcoating

Capital Parking Lot Line Painting recommends the following preparation steps to ensure a successful sealcoating job in Barrie:

  1. Inspection: Assess the asphalt for cracks, potholes, or damage that needs repair before sealcoating.
  2. Cleaning: Use power washing to thoroughly clean the surface, removing all contaminants.
  3. Drying: Allow the surface to dry completely after washing to prevent moisture from trapping under the sealcoat.
  4. Crack Filling: Repair cracks and fill potholes to create a smooth surface.
  5. Sealcoating Application: Apply the sealcoat evenly with professional equipment.

Common Mistakes to Avoid When Preparing for Sealcoating

  • Skipping power washing: Failing to clean the surface can cause poor adhesion and reduce sealcoat lifespan.
  • Sealing wet asphalt: Applying sealcoat before the surface dries traps moisture, leading to bubbling and peeling.
  • Ignoring repairs: Sealcoating over damaged areas does not fix underlying problems and can worsen over time.
  • Not hiring professionals: Attempting to sealcoat without proper experience or equipment can yield unsatisfactory results.
