Why is granite rarely painted compared to concrete outdoor sculptures?

Granite is rarely painted compared to concrete in outdoor sculptures due to its natural durability and aesthetic appeal. Unlike concrete, granite is highly resistant to weathering, requiring minimal maintenance. Its rich, natural colors and textures often make painting unnecessary, as it would mask its inherent beauty. Concrete, on the other hand, is more porous and prone to cracking, making paint a protective and decorative layer. Additionally, granite's dense surface doesn't adhere well to paint, leading to peeling over time, while concrete's roughness holds paint more effectively. These factors make granite a preferred choice for long-lasting, low-maintenance outdoor art.
