SEALCOATING

What is Sealcoating?

• Sealcoating is the application of a protective coating to asphalt-based pavements.

• It’s a mixture of water, sand, polymers, and other additives that forms a protective layer.

Purpose of Sealcoating

• Protection: It shields the asphalt from oxidation, UV rays, and chemical spills.

• Longevity: Sealcoating extends the life of the pavement by preventing damage from various elements.

Benefits of Sealcoating

• Prevents Oxidation: The sun’s rays can dry out the asphalt, making it brittle and prone to cracks. Sealcoating slows down this process.

• Waterproofing: It fills in cracks, preventing water from seeping in and causing further damage, especially in freezing conditions.

• Aesthetic Appeal: Sealcoating gives the pavement a fresh, new look, enhancing its appearance.

• Fuel Spill Resistance: Asphalt and gasoline have similar chemical makeups, so fuel spills can soften and weaken the pavement. Sealcoating creates a barrier against this.

Process of Sealcoating

1. Cleaning: The surface must be clean and free of debris.

2. Repairing: Any existing cracks or holes should be filled before sealcoating.

3. Application: The sealcoat can be applied using a sprayer or squeegee.

4. Drying: The coating needs to dry and cure, which can take several hours or up to a few days, depending on the product and weather conditions.

When to Sealcoat

• New Asphalt: It’s recommended to wait at least 6 months after new asphalt is laid before sealcoating.

• Frequency: Every 2-3 years, or as needed, depending on traffic and weather conditions.

Considerations

• Weather: Sealcoating should be done in dry weather.

• Curing Time: It’s important to keep vehicles off the newly sealcoated surface for the recommended curing time.

Sealcoating is a cost-effective way to maintain asphalt pavement and prevent costly repairs in the future. It’s a straightforward task that, when done correctly, does not need to be carried out often but provides long-lasting benefits.
