City officials in Phoenix are scheduled to unveil a 200-foot mural Saturday along a flood control structure at Cave Creek Sweetwater Park in north Phoenix, marking the first time the material has been used for a mural, KJZZ reported.
Painting a Desert Landscape With Thermal Coatings
The artwork, created by artist Nicole Poppell, features a distinct desert theme punctuated by splashy shades of yellow and blue. Phoenix City Councilwoman Debra Stark described the finished visual addition to the neighborhood as spectacular.
Yet the project’s true distinction lies entirely beneath the pigments. Workers painted the mural using a material called EnKoat, a specialized surface coating typically reserved for commercial and residential rooftops.
City officials initiated the project after local neighborhood leaders requested a fresh mural for the park. Stark and community organizers wondered whether the thermal-blocking properties proven on roofs could translate effectively to vertical park infrastructure.
Testing Lower Temperatures on Concrete Walls
Following Saturday’s unveiling, the City of Phoenix plans to collaborate with researchers to analyze whether the experimental paint meaningfully reduces local surface or air temperatures surrounding the mural. Stark noted that while traditional measures like planting shade trees remain essential, exploring material science offers an additional avenue to combat intense summer heat.
If the testing proves successful, city leaders intend to weigh further investments in reflective architectural coatings as part of broader municipal cooling strategies.
The Science and Precedent Behind the Paint
The company behind the medium, EnKoat, is a Phoenix-based enterprise founded by Matthew Aguayo and Aashay Arora while they were doctoral students in Arizona State University’s School of Sustainable Engineering and the Built Environment. According to ASU News, the firm’s core products are engineered to cut energy consumption, prolong roof lifespans, and act as moisture barriers against extreme weather.
EnKoat has previously partnered with ASU and the Salt River Project on a two-year evaluation of its IntelliKoat coating across a 40,000-square-foot repository. That research tracks performance metrics against sections of the structure left uncoated.
Utilizing reflective finishes for public cooling initiatives has gained traction elsewhere. In New Haven, Connecticut, a community-driven basketball court mural named Chromatic Drift was unveiled on June 10, 2026, at the Betsy Ross Arts and Design Academy. Developed with participation from over 200 students and volunteers, that project demonstrated that specialized cool coatings can reduce surface temperatures by up to 10 degrees Fahrenheit and lower surrounding air temperatures by up to 3.5 degrees during extreme heat events.
