Large-Scale Parking Lot Sealcoating: Lessons from a 2.2 Million Square Foot Project

When it comes to sealcoating, few projects test a contractor’s organizational skills quite like a 2.2 million square foot parking lot with a firm two-week deadline. Advanced Pavement Technologies (APT) faced exactly this challenge at Six Flags Great Adventure in New Jersey, where they were tasked with repairing, sealcoating, redesigning the layout, and striping the entire parking lot before the amusement park’s season opening. The job demanded meticulous planning, the right equipment, and a strategic approach to pre-mixed sealer delivery that allowed crews to maximize every hour of workable time. For contractors looking to take on large commercial sealcoating projects, the lessons from this job offer a blueprint for success. Understanding how to stage materials, coordinate multiple work crews, and leverage ready-to-use sealer products can mean the difference between a profitable, on-time completion and a logistical nightmare. Whether you are bidding on a shopping center lot, a corporate campus, or an entertainment venue, mastering the principles behind high-volume sealcoating operations is essential for growth.

Project Planning and Staging Area Setup

Before any sealer touched the pavement, APT invested heavily in pre-job planning. The single most important decision they made was establishing a dedicated staging area. Located in a corner of the lot just off a main entry road, the staging area served as the operational hub for the entire project. Measuring 200 feet by 70 feet, it contained a 20-yard dumpster, a portable toilet, the SealMaster 4,800-gallon pre-mix tank, two Bobcats, an enclosed equipment container, a milling machine, a paver, a sweeper, and all the sand, additives, and spray tips needed for the job. Everything was backed into position at the end of each shift so crews could pull out and start working immediately the next morning.

Why Staging Areas Matter for Large Commercial Lots

Improved Organization and Safety

A central staging area keeps equipment consolidated, reducing the risk of accidents from vehicles moving randomly across the job site. On the Six Flags project, this containment meant no trucks were scattered across 2.2 million square feet of parking lot. Crews always knew where to find tools and materials, which minimized downtime and created a safer working environment.

Faster Daily Start-Up

The practice of backing all equipment into the staging area at night allowed crews to drive out straight in the morning. On a job with a tight two-week window, every minute saved in setup translated directly into more square footage sealcoated. APT’s owner, Andrew Muller, emphasized that the staging area “saved us so much time” and made it possible to meet the deadline despite multiple rain delays.

Streamlined Material Delivery

Large sealcoating jobs depend on just-in-time delivery of sealer, sand, and additives. With a staging area, tanker trucks could pull in, offload, and leave without interfering with active sealcoating operations. APT coordinated with SealMaster to receive 4,800-gallon tankers on an as-needed basis, with each new tanker arriving just before the previous one ran dry. This seamless logistics chain kept spray crews working continuously.

Key Elements of an Effective Staging Area

• Easy access for material delivery trucks with room to maneuver
• Proximity to the largest or most critical work zones
• Secure storage for equipment and supplies overnight
• Sanitary facilities to keep crews on site rather than leaving the job
• Dedicated areas for mixing, loading, and equipment parking

Pre-Mixed Sealer: The Key to High-Volume Production

One of the most impactful decisions APT made was using ready-to-use pre-mixed coal tar sealer delivered in 4,800-gallon tankers equipped with agitators. Rather than having crews spend time at a hydrant measuring water and mixing sealer from scratch, the pre-mix arrived with water already metered to specification. All APT’s crew had to do was add sand and additive before spraying. This approach dramatically improved both the speed and consistency of the sealcoating operation.

Advantages of Pre-Mixed Sealer Delivery

How Pre-Mix Enabled Six Days of Continuous Sealcoating

APT divided the parking lot into four 500,000-square-foot sections and sealed them sequentially. On peak days, they went through four full tankers of pre-mix. The first coat was applied using a 1,000-gallon unit with an air-assisted spray bar, while the second coat was applied using two 550-gallon units. Sealcoating began on Day Six of the project and continued for six days, with crews waiting at least a day between coats to allow proper curing. In total, APT applied 40,000 gallons of pre-mix sealer and 18 pallets of sand and additives over the course of the job.

Cost and Labor Savings from Pre-Mix

APT owner Ted Wilson noted that having ready-to-use sealer “was very important for getting the job done on time, for saving labor costs, and for making the work easier on our employees. It saved the time of going to the hydrant, putting the water in, and working to get the right mix every time.” The result was a more consistent final product and a crew that could focus on application quality rather than batch preparation.

Coordinating Multiple Work Crews on a Tight Schedule

Beyond sealcoating itself, the Six Flags project required extensive preparatory work: removing 4,900 lineal feet of 8-inch concrete curbs, milling concrete tramways, removing more than 50 speed bumps, pulling 650 concrete parking bumpers and their metal stakes, taking out signs with posts buried 3 feet deep in asphalt, and filling the resulting holes. APT deployed 12 workers per day across multiple crews, with each crew handling a different aspect of the preparation simultaneously.

Orchestrating Simultaneous Workstreams

Rather than sequencing work linearly, APT ran parallel operations from Day One. A sweeper kept pavement clean and dust down continuously. Workers hand-cleaned areas the sweeper could not reach. A crew using a Bobcat with a fork attachment removed signs and parking bumpers. A three-person crew milled concrete tramways. Another crew milled speed bumps. This parallel approach allowed APT to compress what could have been a three-week preparation phase into just five days.

1. Day 1-2: Staging area setup, sign and bumper removal, initial sweeping, concrete tramway milling
2. Day 3-5: Continue removal work, fill holes from removed posts, receive paint and sealer deliveries, begin milling curbs
3. Day 6-11: Begin sealcoating in completed sections while continuing prep work in remaining areas
4. Day 12-13: Final sealcoating, clean-up, prepare for striping
5. Day 14 (May 5): Project complete on schedule

Innovative Curb Removal Strategy

One of the most time-saving decisions came during curb removal. APT initially planned to use a backhoe to remove 8-inch concrete curbing in large chunks, haul them to the staging area, and pay for disposal. Instead, they tried running a milling machine directly over the curbing. It worked so well that what would have been a multi-day labor-intensive operation became a quick, clean milling pass. Wilson noted the milling machine “went right through the curbing. It was so much quicker and much less labor-intensive than using a backhoe.”

Managing Weather Delays and Client Expectations

Rain posed a persistent challenge, with wet pavement delaying work on Days 3, 4, 5, and 7. Rather than losing those days entirely, APT planned for weather-resilient work tasks that could continue in wet conditions. Sign removal, hole filling, and equipment maintenance kept crews productive even when the pavement was too wet for sealcoating. This contingency planning was critical to hitting the May 5 deadline.

Communication and Coordination with the Client

Six Flags presented additional challenges: the park was shooting a television commercial and operating on a limited pre-season schedule while APT was working. Coordinating with the property manager required constant communication. APT assured Six Flags management from the outset that the job would be completed on time, and after all the rain delays, Muller said, “I was thrilled to deliver.” The key was setting realistic expectations early and maintaining transparent communication about progress and setbacks throughout the project.

Lessons for Contractors Taking on Large Sealcoating Projects

• Always build a staging area into your bid and job plan for lots over 100,000 square feet
• Partner with a sealer supplier who can deliver pre-mix tankers on a just-in-time schedule
• Plan for rain days by identifying preparation work that can proceed in wet conditions
• Divide large lots into manageable sections and seal one section at a time
• Consider alternative methods for demolition tasks such as milling instead of excavating
• Maintain daily communication with the property manager to align on access and scheduling

SealMaster’s Mike Tarvin summed up the financial lesson succinctly: “The price you pay for the sealer does not matter nearly as much as the efficiency in which you can put the product on the ground. That truly determines your profitability.” APT’s success on the Six Flags Great Adventure project demonstrates that with proper planning, the right material delivery system, and parallel work coordination, even the most complex large-scale sealcoating job can be completed on time and on budget. Contractors looking to grow their commercial sealcoating business should study these principles and apply them to their own operations.
