Sealcoating for Asphalt Crack Prevention

What is Sealcoating?

Sealcoating is a protective layer of asphalt coating that is applied to the surface of paved roads, driveways, and parking lots. It helps to protect the asphalt from the damaging effects of sunlight, rain, snow, and other external factors. Sealcoating also enhances the appearance of the pavement, making it look smooth and black.

The Importance of Preventing Asphalt Cracks

Preventing cracks in asphalt is crucial for maintaining the integrity and longevity of the pavement. Cracks are one of the main causes of pavement deterioration and can lead to more extensive damage, such as potholes. Once cracks start to form, they allow water to penetrate the pavement, which weakens the base and subbase layers. Over time, this can result in the formation of potholes and the need for costly repairs.

How Sealcoating Helps Prevent Asphalt Cracks

Sealcoating acts as a protective barrier that seals the asphalt surface and prevents water, oil, and other substances from penetrating the pavement. It fills in small cracks and gaps, preventing them from expanding and becoming larger. By reducing the amount of water that infiltrates the pavement, sealcoating helps to preserve the strength and structural integrity of the asphalt.

The Benefits of Sealcoating

There are several benefits to sealcoating asphalt surfaces regularly:

  • Crack prevention: As mentioned earlier, sealcoating helps to prevent the formation and expansion of cracks, preserving the pavement’s integrity.
  • Protection from weathering: Sealcoating protects the asphalt from the damaging effects of sunlight, rain, snow, and other weather elements. It prevents oxidation, which can cause the asphalt to become brittle and prone to cracking.
  • Improved appearance: Sealcoating gives the pavement a fresh, black appearance, making it look well-maintained and aesthetically pleasing.
  • Cost savings: Regular sealcoating can extend the lifespan of the pavement, reducing the need for costly repairs and replacements.
  • Overall, sealcoating is a cost-effective way to protect and preserve asphalt surfaces, ensuring their longevity and minimizing the need for extensive repairs or replacements.

    When to Sealcoat

    The ideal time to sealcoat asphalt surfaces is when the pavement is still relatively new and in good condition. Sealcoating should ideally be done every 3-5 years, depending on the amount of traffic and weather conditions the pavement is exposed to. It is important to sealcoat before any significant cracking occurs to prevent further damage.

    The Sealcoating Process

    Sealcoating is typically performed by professional contractors who have the necessary equipment and expertise. The process involves the following steps:

  • Cleaning: The pavement is thoroughly cleaned using power washers to remove dirt, debris, and any loose material.
  • Crack filling: Any existing cracks are filled with a rubberized asphalt crack filler to prevent water infiltration.
  • Sealcoating application: The sealcoat material is applied using a spray system or squeegee. Multiple thin coats may be applied to achieve the desired protection and appearance.
  • Cure time: The sealcoat needs time to cure and dry before it can be trafficked. This typically takes 24-48 hours, depending on weather conditions.
  • It is important to note that sealcoating should only be performed in optimal weather conditions. The temperature should be above 50°F and there should be no rain in the forecast for at least 24 hours after application.

    Maintenance Tips for Sealcoated Surfaces

    To maximize the effectiveness of sealcoating and prolong the life of the pavement, it is important to follow these maintenance tips:

  • Regular cleaning: Keep the pavement clean by regularly sweeping away debris and dirt. This prevents the buildup of harmful substances and extends the life of the sealcoat.
  • Avoid heavy traffic: Avoid parking heavy vehicles or equipment on freshly sealcoated surfaces for at least 48 hours. This allows the sealcoat to fully cure and prevents damage.
  • Address cracks promptly: If cracks start to form after sealcoating, have them repaired immediately to prevent further damage to the pavement.
  • By following these maintenance tips, you can ensure that your sealcoated asphalt surfaces remain in optimal condition and continue to provide long-lasting protection.

    In conclusion

    Sealcoating is an essential preventive maintenance technique for asphalt surfaces. By applying a protective sealcoat, you can prevent the formation and expansion of cracks, enhance the appearance of the pavement, and extend its lifespan. Regular sealcoating, combined with proper maintenance, can save you significant time and money in the long run by minimizing the need for costly repairs or replacements. So, if you want to protect your asphalt surfaces and keep them in top condition, sealcoating is the way to go!
