A satin finish is a type of surface treatment that provides a soft sheen, falling between matte and glossy finishes. It reflects light gently, creating a smooth appearance without being overly shiny. This finish is commonly used in various applications, including paint, wood, and metal surfaces, offering a balance of elegance and durability. Satin finishes are popular in home decor, especially for walls and furniture, as they are easier to clean than matte finishes while still hiding imperfections. They are also frequently used in fabrics, such as satin textiles, which are known for their luxurious feel and subtle luster.
