Commercial Asphalt Services in Sun Prairie, Wisconsin

Sealcoating is a liquid sealant applied to asphalt surfaces to protect them from:

• Sun damage: The sun’s UV rays can dry out and crack asphalt, leading to potholes and other problems. Sealcoating creates a barrier that reflects UV rays, keeping your asphalt cooler and preventing cracks.
• Water damage: Water can seep into cracks and freeze, further expanding them and causing even more damage. Sealcoating fills small cracks and helps prevent water from penetrating the asphalt.
• Oil and gas spills: These substances can soften and break down asphalt. Driveway sealcoating creates a barrier that helps prevent spills from damaging your pavement.

While DIY sealcoating is an option, hiring a professional like Hallman Asphalt & Sealing ensures a higher-quality, longer-lasting result.

There isn’t a single schedule that works for every parking lot. Traffic volume, pavement age, sun exposure, drainage, previous maintenance, and overall condition all affect how quickly asphalt deteriorates. Many commercial properties are evaluated for sealcoating every 2–3 years, but Hallman Asphalt recommends basing the decision on the actual condition of the pavement rather than automatically sealing on a fixed schedule.

Sealcoating requires warm, dry conditions so the material can properly cure. In Wisconsin, that generally makes the warmer months the appropriate sealcoating season. Temperature, humidity, rain, and the forecast all matter, so Hallman Asphalt schedules projects when conditions are suitable for proper application and curing.

Yes. Sealcoat is a protective surface treatment, not a structural repair. Cracks should typically be cleaned and filled, while potholes and deteriorated areas may require asphalt patching before sealcoat is applied. Preparing these areas first helps address the underlying problems rather than simply covering them.

Cure time depends on weather conditions, the product being applied, and the specific project. Commercial lots generally need to remain free of vehicle traffic while the sealcoat cures. Hallman Asphalt can help plan the project in phases when appropriate, allowing businesses and larger properties to maintain access while work is completed.

Yes. Sealcoating and line striping are commonly completed as part of the same parking lot maintenance project. After the sealcoat has sufficiently cured, new parking spaces, accessible markings, traffic markings, and other required lines can be applied to the refreshed surface. Combining services can minimize disruption while giving the entire lot a clean, finished appearance.
