Coatings, commonly referred to as paint, are protective or decorative layers applied to a surface. These substances consist of pigment, binder, solvent, and additives. Pigments provide color and opacity, while binders hold the pigment particles together and adhere the coating to the substrate. Solvents, typically water or organic compounds, are used to dissolve the binder and control viscosity, evaporating after application to allow the coating to dry. Additives are incorporated to enhance specific properties such as durability, drying time, or resistance to mildew.

Coatings are applied to a wide array of surfaces including wood, metal, plastic, and masonry. Their primary functions include aesthetic enhancement, corrosion protection, weather resistance, and improved hygiene. For example, house paints protect buildings from the elements and offer visual appeal, while industrial coatings safeguard machinery and infrastructure from rust and chemical damage. The type of coating used depends on the substrate, the intended environment, and the desired performance characteristics. Common application methods include brushing, rolling, spraying, and dipping. The selection and application of coatings are critical for the longevity and functionality of many manufactured goods and structures.
