Process	Painting
	Painting is performed for protection reasons. Paints protect metals and steels from rust, wood from decomposition, concretes from carbonizing. Besides, paints are used against wear and friction, for decoration, identification, warning, and security. Paints are a fluid material composed of pigments, binders, fillers, solvents, and additives. According to the type of each of these components, many different kind of paints can be produced. Commonly, they are classified according to the type of binder. Paints can be applied to a surface and, after drying, they form a thin, continuous film with good adhesion. Drying can be physical (e.g. tar, bitume, acryl, vinyl) or chemical (e.g. epoxies.)

Category	Surface treatments
Materials	Substrates: Metals Wood Ceramics Paints: Alkyd paints Aqueous acrylic dispersions Chlor caoutchouc paints Epoxy paints Tar-epoxy systems
Environmen- tal notes	Depending on the components, paints can be harmful for the environment, as well as for the human health.
Additional info	The result of painting strongly depends on many variables, such as substrate, ambiental conditions, previous surface treatments, binder, number of layers, and painting method.
