The article describes the intervention by artisan Davide Incredibile, who performed a cleaning and treatment on a Spanish terracotta floor in a prestigious apartment in Piazza Navona. Thanks to Marbec products and the artisan’s skill, the floor has gained a timeless beauty and elegance. The treatment included the use of IDROWIP for pre-installation protection, VIACEM for descaling cleaning, ANTISTAIN for stain protection, PALLADIUM for a uniform finish, and IDROFIN MATT for a satin appearance. This intervention perfectly exemplifies how the combination of professionalism and high-quality products can enhance the historic spaces of Rome.
