Should You Sealcoat Before or After Line Painting?
If you're considering a parking lot renovation in Whitby, one crucial decision is whether to sealcoat before or after line painting. Capital Parking Lot Line Painting, a trusted expert in the industry, can guide you through this process.

What is Sealcoating?
Sealcoating is a protective coating applied to asphalt surfaces to extend their lifespan. It helps prevent cracks, potholes, and other damage caused by harsh weather conditions, vehicle traffic, and UV rays.
Benefits of Sealcoating
- Protects the asphalt from oxidation and water damage
- Enhances the appearance and curb appeal
- Extends the life of the asphalt surface
- Provides a slip-resistant surface
Sealcoating Before Line Painting
Many experts recommend sealcoating your parking lot before line painting. Here's why:
Advantages
- The sealcoat acts as a primer, ensuring better adhesion of the line paint
- The line markings will last longer on a freshly sealcoated surface
- You can address any cracks or repairs before applying the sealcoat
Disadvantages
- The sealcoat needs to cure completely before line painting, which can delay the project
- If the sealcoat is not applied evenly, it may affect the appearance of the line markings
Sealcoating After Line Painting
Some contractors prefer to line paint first and then sealcoat. Here are the pros and cons:
Advantages
- The line markings are less likely to be damaged during the sealcoating process
- You can complete the line painting and sealcoating in a shorter timeframe
Disadvantages
- The sealcoat may not adhere as well to the line markings, reducing their lifespan
- Any repairs or cracks need to be addressed after line painting, which can be more challenging
The Verdict
According to Capital Parking Lot Line Painting, a reputable company serving Whitby and the surrounding areas, the best practice is to sealcoat before line painting. This approach ensures better adhesion, longer-lasting line markings, and a more durable surface overall.

However, the decision ultimately depends on your specific needs, budget, and timeline. Capital Parking Lot Line Painting can assess your parking lot and provide expert guidance on the best approach for your project.
