Precision and Performance: Our Matthews Paint Mixing System and Paint Booth


At Port City Signs & Graphics, we’re always looking for ways to deliver the highest quality signage for our clients. One recent investment — the Matthews Paint Mixing System and a new ETL-listed semi-downdraft paint booth — takes our in-house painting capabilities to the next level. These upgrades give us complete control over the paint process, ensuring consistent, durable finishes that perfectly match your brand colors.

Why Matthews Paint? The Industry Standard for Signs

Matthews Paint has long been recognized as the sign industry’s go-to choice for durability, precise color-matching, and reliable performance. While we’ve used Matthews Paint for years, we previously had to order pre-mixed paint from vendors. That meant delays, occasional errors, and wasted product when we only needed a small batch.

Now, with the Matthews Paint Mixing System in our shop, we can:

  • Mix colors on demand! From a half-pint to multiple gallons.
  • Match corporate and brand colors with exact precision, including PMS specifications.
  • Reduce waste by mixing only what’s needed, saving on costs and safe disposal.
  • Turn projects around faster with no waiting on outside shipments.

In today’s world, brands expect perfect consistency across every detail of their signage, and this system lets us deliver exactly that.

A State-of-the-Art Paint Booth

Of course, mixing the right paint is only part of the process. Our new semi-downdraft paint booth provides a clean, controlled environment to apply those custom finishes. With interior dimensions of 14' x 9' x 26'5", it accommodates both small and large painted components.

Key features include:

  • Double-filtered air intake and exhaust systems for a dust-free environment.
  • Consistent airflow and lighting for smooth, even application.
  • Certified safety and compliance with NFPA-33 and OSHA standards.
  • Eco-friendly design that reduces fumes and improves air quality for our team.

The result? A flawless finish that not only looks better but also performs better outdoors over time.

What This Means for You, Our Clients

These upgrades impact nearly every painted sign we produce, from dimensional letters and architectural signage to custom projects with detailed designs. Whether you’re a corporation protecting brand standards, a university maintaining consistent colors across campus, or a design and branding agency wanting to ensure color consistency for your clients:

  • Faster turnaround times with in-house mixing and spraying.
  • Durability and longevity thanks to Matthews’ industry-leading formulations.
  • Creative possibilities, including fades, gradients, and specialty finishes.

One recent example: a sailfish sign for Seapath Marina and Yacht Club. Our precision sprayers, combined with Matthews Paint and the booth’s clean application, allowed our painters to capture gradients and detail that make the design stand out.

Staying on the Cutting Edge

We don’t like to compare ourselves to other sign companies…we’d rather let our work speak for itself! What we can say is this: by investing in the same systems trusted nationwide by the sign industry’s leaders, at Port City Signs & Graphics, we’re bringing a higher level of precision, consistency, and efficiency to Wilmington and beyond.

It’s all part of our commitment to staying at the forefront of what’s possible in custom signage.  This way, you, our clients, can be confident your signs will look exactly as envisioned, down to the very last detail.
