A
layer or film spread over a surface for protection or decoration
coatings are high grade products that can provide decorative appeal but are
primarily designed to protect the substrate from degradation either from
environmental or chemical actions. It is both metals and nonmetals such as concrete, brick, plastics, and timber deteriorate in natural environments.
Protective

are designed to seal off the substrate from these damaging reactions
thus preventing corrosion. A correct, well planned choice of paint system for
buildings & structures and its subsequent maintenance is decisive, in the
long run, to its profitability.
