Preserving an American Icon in the Heart of Denver

Some structures are painted. Others are protected.

Standing 272 feet above downtown Denver, the Colorado State Capitol Dome remains one of Colorado’s most defining landmarks. Its gold-leaf finish represents the state’s mining heritage and the craftsmanship that shaped the West. When its coating system began to fail only a few years after a major rehabilitation, the State relied on BASE Painters to take on the Capitol Dome Restoration that others could not complete.


The result was an award-winning restoration that returned the structure to its iconic brilliance and protected its legacy for decades to come.


Project Overview

Client: State of Colorado – Department of Personnel & Administration

Location: Denver, Colorado

Structure: Historic Capitol Dome

Height: 272 ft (83 m)

Scope: Full coating removal, surface restoration, and gold-finish renewal

Access Method: Rope access + contained scaffolding

Products: Sherwin-Williams Fluorokem HS, vapor-blasting system

Duration: Summer 2018 – 2019

Award: CoatingsPro Magazine — 1st Place, Specialty Project

The Challenge

When BASE arrived onsite, the dome’s coating system, installed during a 2016 rehabilitation, had already begun to delaminate and fade across the copper exterior. The failure went far beyond appearance. It placed the long-term protection of one of Colorado’s most important historic structures at risk.


This Capitol Dome Restoration required a specialized balance of precision, preservation, and access:

  • Rope access expertise to reach the upper geometry where scaffolding could not be installed

  • Historic material protection during the removal of failed coatings

  • Performance under intense UV exposure, high altitude, and unpredictable Denver weather


This was not a simple repaint. It was a structural preservation effort performed at height on a landmark that receives statewide attention.


Execution: Precision at Every Height

BASE Painters removed the failed coatings down to bare copper using vapor blasting, a controlled and highly accurate process that cleans without sacrificing the metal’s integrity. Once the surface was restored, the team applied Sherwin-Williams Fluorokem HS, a long-life fluoropolymer engineered for extreme UV resistance and color stability that is essential for a mile-high gold dome.


Every phase was performed using rope-access protocols, allowing the crew to move efficiently across the dome’s contours while maintaining full public safety and leaving Capitol operations uninterrupted.


Results: A Capitol Dome Reborn

The Colorado State Capitol Dome once again shines across the Denver skyline. The new coating system is built to withstand altitude, weather, and UV exposure for decades.


Outcome Highlights:

  • Complete removal of failed coatings

  • Copper surface restored with meticulous preservation

  • Application of long-life Fluorokem HS system

  • Rope-access completion with zero safety incidents

  • National industry recognition for craftsmanship and execution


This Capitol Dome Restoration did more than correct a failure. It reaffirmed the dome as one of Colorado’s most enduring symbols.


From above, the Capitol Dome Restoration shows its true scale, with BASE crews restoring one of Colorado’s most iconic structures.

Talk to BASE Painters

When your structure is historic, iconic, or simply too important for anything less than precision, you need a team built for projects others walk away from.
