Do You Need to Power Wash Before Sealcoating?

Sealcoating your asphalt parking lot is essential to protect it from the elements and extend its lifespan. But before applying sealcoat, one question often arises: do you need to power wash first? In this article, we explore why power washing is a critical step in the sealcoating process, especially for properties in Mississauga, and how Capital Parking Lot Line Painting ensures top-notch service every time.

Sealcoating Preparation

Why Is Power Washing Important Before Sealcoating?

Power washing removes dirt, debris, oil stains, and other contaminants from the asphalt surface. These impurities can prevent the sealcoat from adhering properly, resulting in a patchy or prematurely worn finish. In cities like Mississauga, where weather conditions can cause rapid wear and tear, thorough preparation is key.

The Role of Surface Preparation

Proper surface preparation, including power washing, ensures the sealcoat bonds effectively. Without this step, trapped grime beneath the sealcoat can cause bubbling or peeling, undermining the protective benefits of the treatment.
