Coating refers to the application of a layer of material onto a surface to enhance its properties or appearance. This process can protect surfaces from corrosion, wear, and environmental damage, making it essential in industries like construction and manufacturing. Common types of coatings include paints, varnishes, and sealants, each serving specific purposes based on the material and desired outcome. Coatings can be applied using various methods, such as spraying, brushing, or dipping. The choice of method often depends on the size and shape of the object being coated, as well as the type of coating material used. Proper application ensures durability and effectiveness, contributing to the longevity of products like automobiles and furniture.
