Do You Need to Power Wash Before Sealcoating?
Sealcoating your asphalt parking lot is an essential step to extend its life and keep it looking fresh. But before you apply that protective seal, there’s an important question to ask: do you need to power wash before sealcoating? In this post, we explore why thorough cleaning matters and how it impacts the quality of your sealcoat, especially for businesses in Markham.
Why Sealcoating Matters for Your Parking Lot
Sealcoating is more than just a cosmetic upgrade. It protects your asphalt from the damaging effects of UV rays, oil spills, water infiltration, and harsh weather conditions. For cities like Markham, which experiences a range of weather throughout the year, sealcoating provides a crucial barrier that helps prevent cracks and potholes from developing.
Companies like Capital Parking Lot Line Painting understand the importance of proper surface preparation to ensure the sealcoat adheres well and lasts longer.
The Role of Power Washing Before Sealcoating
What Does Power Washing Do?
Power washing is the process of using high-pressure water to remove dirt, grime, oil stains, loose debris, and old sealcoat residues from the asphalt surface. This step is vital because sealcoat needs a clean surface to bond effectively. Without proper cleaning, the sealcoat may peel, bubble, or wear unevenly.
Can You Skip Power Washing?
While it might be tempting to skip power washing to save time, doing so can compromise the quality of your sealcoating project. Dirt and debris act as a barrier between the sealcoat and asphalt, reducing adhesion and allowing moisture to seep underneath.
Capital Parking Lot Line Painting in Markham always recommends power washing as a standard part of their sealcoating preparation process to ensure a smooth, long-lasting finish.
Benefits of Power Washing Before Sealcoating
- Improved Sealcoat Adhesion: Clean surfaces allow sealcoat to bond properly, reducing premature peeling.
- Removal of Harmful Contaminants: Oils and chemicals can degrade sealcoat if not cleaned off.
- Enhanced Appearance: A clean surface provides a smoother, more uniform finish.
- Increased Longevity: Proper prep extends the life of your sealcoat, saving future maintenance headaches.
- Prevents Moisture Trapping: Dirt and debris can trap water, leading to cracks and potholes beneath the sealcoat.

Common Mistakes to Avoid When Sealcoating Without Power Washing
- Skipping Cleaning: Leads to poor sealcoat adhesion and early failure.
- Applying Sealcoat on a Wet Surface: Moisture interferes with curing and bonding.
- Using Inadequate Equipment: Inefficient cleaning can leave behind oils or dirt.
- Ignoring Repairs: Sealcoating over cracks or potholes without prepping first reduces effectiveness.
