Finishing compounds are materials used to enhance the surface quality of various products, particularly in woodworking and metalworking. They help achieve a smooth, polished finish by filling in imperfections and providing a protective layer. Common types include wood stains, varnishes, and polishes, each serving different purposes depending on the desired outcome. These compounds can be applied through various methods, such as brushing, spraying, or wiping. The choice of finishing compound often depends on the material being treated and the specific finish desired. Proper application can significantly improve the durability and appearance of the finished product.
