In most cases, it does not require any treatment or modification except cutting, sawing and mechanical finishing. The fact that thousands of years old stone buildings are still functional confirms its durability. Most stones require minimal maintenance and retain the aesthetics for their lifetime. Since the stone does not require chemical treatment or painting, it creates a health-friendly interior.
