Frequently Asked Questions About Sealcoating in New Jersey

Sealcoating is a protective coating applied directly to the surface of asphalt pavement. It seals the top layer of asphalt, protecting it from damage caused by sun, rain, snow, ice, salt, oil, and daily wear. It also restores a clean, fresh black finish to your pavement.

Asphalt is naturally porous and breaks down over time when exposed to the elements. Sealcoating creates a protective barrier that slows oxidation, prevents water from penetrating the surface, and extends the life of your pavement significantly. Regular sealcoating is one of the most cost effective ways to protect your pavement investment.

Most driveways and parking lots should be sealcoated every three to four years depending on traffic, exposure, and the condition of the pavement. New asphalt should be allowed to cure for at least one full year before the first sealcoating application.

In New Jersey sealcoating is best done during warmer months — typically between late spring and early fall. Sealcoating requires temperatures of at least 50 degrees Fahrenheit and dry conditions to cure properly. Topnotch schedules all jobs to ensure optimal conditions for the best possible result.

Most residential driveways can be completed in a few hours. Commercial parking lots vary depending on size. Topnotch works efficiently to minimize disruption to your home or business.

We recommend waiting at least 24 to 48 hours before walking or driving on a freshly sealed surface. This allows the sealcoat to cure fully and ensures the best possible finish. Curing time can vary depending on temperature and humidity.

Before sealcoating your pavement should be clean and free of debris, oil stains, and vegetation. Any significant cracks should be filled prior to sealcoating for the best result. Topnotch will assess your pavement before every job and recommend any necessary preparation work.
