Project Spotlight: Concrete Grind and Seal at the Caldwell Airport Terminal

At Spray ’n Coat Painting, we often get called in to finish what others couldn’t quite get right—and that was the case with this 2,000 sq. ft. concrete floor coating project at the Caldwell Airport terminal. The building, now home to a private charter company, needed a durable and clean finish to make the space more welcoming for employees and travelers.

Project Background

This terminal originally had carpet in several areas, and after it was removed, thick glue residue was left behind across the concrete floors. Our customer had hired another contractor to handle the coating work, but unfortunately, they lacked the necessary equipment and experience for the job. That’s when we stepped in to get things done right.

Our Process

To give the customer the clean, sealed finish he was hoping for, our crew tackled the job in several key steps:

• Joint Filler Replacement: We started by removing the old joint filler and refilling the seams.
  
  
• Heavy Grinding & Surface Prep: Using professional grinding equipment, we stripped away all glue residue and opened up the pores of the concrete to ensure a strong bond.
  
  
• Matte Polyurethane Coating: We applied a commercial-grade polyurethane sealer in a matte finish. This not only improved the look of the space but also provided a stain-resistant, slip-resistant surface that can stand up to heavy foot traffic.
  
  

Why It Matters

For a commercial space like this—where first impressions matter and safety is non-negotiable—the right prep and coating system makes all the difference. The finished floor is now sealed, low-maintenance, and ready to take on day-to-day traffic from both staff and customers.
