How Sealcoating Shields Against UV and Oxidation
Sealcoating is an essential maintenance process that protects asphalt surfaces from harmful environmental factors. In Richmond Hill, where seasonal changes and sun exposure can accelerate pavement deterioration, sealcoating extends the life of your parking lots and driveways. Discover how Capital Parking Lot Line Painting utilizes sealcoating to guard against UV damage and oxidation.
Understanding the Impact of UV Rays on Asphalt
Ultraviolet (UV) rays from the sun penetrate asphalt surfaces and initiate a breakdown of the binder that holds the aggregate together. Over time, this exposure causes the asphalt to lose its flexibility and become brittle, leading to cracks and surface degradation. Richmond Hill experiences varying weather conditions, with ample sunshine that can accelerate this natural aging process.
What is Oxidation and Why is it Harmful?
Oxidation occurs when oxygen molecules react with the asphalt binder, hardening it and making the surface prone to cracking. This chemical change reduces the pavement’s ability to withstand traffic stress and weather fluctuations. Without protection, oxidation can cause premature failure of parking lots and driveways.
Sealcoating: A Protective Barrier
Sealcoating acts as a protective shield, preventing UV rays and oxygen from penetrating the asphalt surface. This process involves applying a specially formulated coating that rejuvenates the pavement binder and seals small cracks and pores.
How Sealcoating Works
- Blocks UV Rays: The dark, reflective coating absorbs and reduces UV radiation that would otherwise damage the asphalt binder.
- Prevents Oxygen Exposure: By forming a waterproof layer, sealcoating limits the asphalt’s contact with oxygen, slowing oxidation.
- Restores Flexibility: Sealcoating replenishes oils lost through weathering, keeping the surface more elastic.
- Reduces Water Penetration: Water is a major factor in pavement deterioration; sealcoating minimizes water ingress that leads to cracks and potholes.

Common Sealcoating Mistakes to Avoid
- Applying Sealcoat on Wet Surfaces: Moisture can prevent proper adhesion and lead to bubbling or peeling.
- Ignoring Surface Preparation: Dirt, oil, and debris must be removed to ensure effective bonding.
- Sealing Over Large Cracks Without Repair: Sealcoating fills small cracks but large cracks require proper patching first.
- Skipping Regular Maintenance: Sealcoating is not a one-time fix; regular reapplication is necessary for optimal protection.
