Surface restoration refers to the process of repairing and rejuvenating the outer layer of various materials, such as wood, metal, or stone. This technique is commonly used in fields like architecture, art conservation, and automotive repair to enhance the appearance and functionality of surfaces that have been damaged or worn over time. The methods of surface restoration can include cleaning, sanding, polishing, and applying protective coatings. These processes help to remove imperfections, restore original colors, and protect against future damage. Surface restoration not only improves aesthetics but also extends the lifespan of the material being treated.
