Interior Commercial Painting In Denver, Lakewood, Highlands Ranch, Littleton and Centennial, CO
Durable and Professional Finishes In High Traffic Areas

Tri-Plex Painting is a family-owned company founded in 1989 by our president, Jeff Lukens. For more than three decades, we’ve built our reputation by delivering consistent, high quality interior painting for commercial and residential properties alike. Whether someone is searching for interior painters near me or commercial painters near me, our focus remains the same: doing the job right the first time and building long-term relationships with our clients.
High-traffic spaces demand more than just a fresh coat of paint. They require experience, proper materials, and attention to detail at every step. From gyms and amenity spaces to hallways and common areas, our approach to interior commercial painting is built around durability, cleanliness, and results that hold up long after the project is complete.
Interior commercial painting in high traffic environments requires a very different approach than a standard office or residential project. Areas like gyms, fitness centers, and shared amenity spaces see constant daily use, repeated contact with walls and doors, and exposure to moisture, heat, and frequent cleaning. To hold up over time, these spaces demand the right products, thorough preparation, and experienced interior painters who understand how commercial spaces actually function.
At Tri-Plex Painting, we approach interior painting in high traffic areas with durability, cleanliness, and long term performance as the top priorities. Gyms, in particular, present unique challenges free weights brushing walls, equipment being moved daily, and members expecting a clean, professional appearance at all times. That’s why product selection matters just as much as application.
We regularly use high performance paints and primers from Sherwin-Williams and Benjamin Moore that are designed for commercial interiors. These coatings are selected specifically for their washability, scuff resistance, and ability to maintain a consistent finish under heavy use. In many gym and common area projects, proper priming is critical to ensure adhesion and uniform sheen, especially when walls have been previously patched, repaired, or exposed to moisture.
Professional Interior Commercial Painting for Office Environments

Interior commercial painting in an active office setting requires more than technical skill, it requires professionalism, coordination, and clear communication from start to finish. Office spaces are often fully occupied, with employees working around computers, desks, conference rooms, and shared equipment that cannot simply be shut down for a paint project. A successful interior painting job in these environments starts long before the first wall is painted.
At Tri-Plex Painting, we understand that productivity and security are just as important as the finished appearance. Our interior painters are trained to work carefully around office furniture, computers, monitors, sound systems, and sensitive equipment. Every project begins with detailed protection of floors, desks, workstations, and surrounding surfaces. Masking and covering are handled with precision to prevent dust, overspray, or disruption to daily operations.
Preparation is approached with the same level of care. Wall repairs are completed cleanly and efficiently, with sanding and priming performed in a controlled manner to minimize dust in occupied spaces. Clean lines at trim, doors, and transitions are achieved through proper taping and caulking, ensuring the final result looks sharp and professional under office lighting.
One of the most critical elements of interior commercial painting in office spaces is communication. We work closely with building managers and property teams to coordinate schedules that make sense for their operations. Whether that means working in phases, after hours, or focusing on one area at a time, our goal is always to minimize disruption. Throughout the project, we stay in constant contact with building management, providing daily updates and addressing any adjustments as they arise.
This level of coordination has allowed us to successfully complete projects in active office environments for clients such as JLL (Jones Lang LaSalle) and Google, as well as numerous commercial properties across the Denver metro area. Each project reinforces our belief that professionalism on the job site is just as important as the quality of the paint itself.
We believe a successful job starts with great communication, and our approach reflects that at every stage of the process. Our goal is to have you as a client for life, and we take pride in delivering interior painting services that meet that standard!
High-Performance Coatings for Parking Garage Interiors


Interior painting in parking garages is one of the most demanding environments for any coating system. Concrete walls are porous, uneven, and constantly exposed to vehicle traffic, exhaust, moisture, and daily wear. To achieve a clean, bright result that holds up over time, interior commercial painting in garages requires the right materials, proven application methods, and careful coordination with building management.
Tri-Plex Painting recently completed the interior painting of two tri-level parking garages, transforming the walls to a clean white finish that significantly improved visibility and overall appearance. Brightening a garage isn’t just about aesthetics—it creates a safer, more welcoming environment for employees and visitors while making the space feel larger and better maintained.
For this project, we used Sherwin-Williams masonry primer, specifically designed to penetrate and seal concrete and masonry surfaces. Proper priming is critical in parking garages to ensure consistent coverage and long-term adhesion. The finish coats were applied using Sherwin-Williams SuperPaint Satin, selected for its durability and washability in high-traffic commercial settings. The satin sheen provided a noticeably higher-quality finish than flat coatings, offering improved light reflection while still holding up to routine cleaning and abrasion.
Application technique plays a major role in the longevity of garage coatings. Both the primer and paint were applied using a spray and back-roll method, allowing the material to fully penetrate the grooves, pores, and texture of the concrete walls. This approach ensures even coverage, proper film build, and a finish that performs as intended. The project was completed with two full coats of paint for maximum durability and consistency.
Protection and attention to detail were priorities throughout the process. Our interior painters carefully masked around all signage, electric vehicle charging stations, smoke alarms and detectors, and adjacent surfaces. Floors and surrounding areas were protected to prevent overspray, keeping the garage clean and operational throughout the project.
Just as important as the workmanship was communication. We worked in constant coordination with the building manager, closing off one level at a time so employees could continue parking on the remaining floors. This phased approach allowed the project to move efficiently while minimizing disruption to daily operations—an essential part of successful interior commercial painting in active facilities.
Improved Visibility and Safety Through Brighter Finishes
Beyond appearance and durability, brighter white walls play an important role in overall safety within parking garages—especially those that are enclosed or located beneath buildings. Light-colored finishes reflect available lighting far more effectively than darker or unfinished concrete, helping eliminate shadows and improve visibility throughout the space.
In enclosed garages, better light reflection makes it easier for drivers and pedestrians to see clearly, identify signage, and navigate lanes, corners, and pedestrian walkways. This added brightness contributes to a safer environment by improving sightlines and creating a space that feels more open and secure. The satin finish further enhances this effect by reflecting light evenly without creating glare, making it an ideal choice for high-traffic garage interiors.
By combining high-quality materials with thoughtful color selection, interior commercial painting can significantly improve both the functionality and safety of parking garage environments.
