Common Sealcoating Mistakes and How to Avoid Them Jun 26, 2025

Sealcoating is an essential maintenance practice for preserving the longevity and appearance of asphalt surfaces. However, common mistakes during sealcoating can compromise the effectiveness of the treatment and lead to costly repairs down the line. To help you avoid these pitfalls, Absolute Asphalt, Paving & Sealcoating presents this guide on the most frequent sealcoating mistakes and how to prevent them.

One of the most prevalent mistakes in sealcoating is neglecting proper surface preparation. Before applying a sealcoat, the asphalt surface must be thoroughly cleaned. This involves removing all debris, dirt, and oil stains, which could otherwise prevent the sealcoat from adhering properly. Use specialized cleaners and patch repair products to address grease spots and cracks. Skipping or inadequately performing this step could result in uneven application and peeling of the coating.

Applying sealcoat in adverse weather conditions is another common error. Both temperature and humidity levels can significantly affect the curing process. Ideally, sealcoating should be applied under mild weather, with temperatures consistently above 50°F and without the threat of rain for at least 24 hours. Application in cold or rainy weather can lead to improper drying, resulting in a coating that is soft and prone to damage.

It's essential to avoid applying sealcoat too thickly. While it might seem like a thicker coat would offer more protection, excessive thickness can lead to cracking and peeling. A thin, even coat is most effective and should be applied using proper sealcoating equipment. Over-application not only wastes product but can also compromise the integrity of the asphalt surface.

Avoid using low-quality sealcoating products. Quality truly matters in the long-term performance of sealcoating. Cheaper sealcoat products often lack the necessary components to protect against UV rays, oil spills, and weather-related wear and tear. Investing in high-quality sealants can save money and headaches in the long run, providing a finish that stands up to the elements.

Timing between successive coatings is critical, yet often overlooked. Many property owners make the mistake of reapplying sealcoat too frequently, thinking it will offer extra asphalt protection. However, it is generally recommended to apply sealcoat every 2 to 3 years. Over-sealing can lead to a buildup of coating that will crack and flake, leading to a messy and unsightly surface.

Failing to follow manufacturer guidelines is also a mistake that should be avoided. Each product comes with specific instructions regarding its application process, drying time, and necessary conditions. Deviating from these guidelines can lead to inferior results.

Lastly, they underestimate the importance of hiring professionals. While DIY sealcoating might seem like a cost-effective approach, improper application can cause more harm than good. Professional sealcoating services, like those offered by Absolute Asphalt, Paving & Sealcoating, ensure that every stage of the process is executed correctly for optimal results. Professionals have the expertise, equipment, and products necessary to extend the life of your pavement effectively.

In summary, avoiding these common sealcoating mistakes can significantly enhance the durability and appearance of your asphalt surface. By focusing on proper surface preparation, suitable weather conditions, correct application technique, and quality materials, you can ensure a long-lasting and well-protected pavement. Trusting experienced professionals can make all the difference in achieving the best results for your asphalt surfaces.
