Painting

The terms paint and coating are used interchangeably and there is no accepted definition that explain their difference. In industry paints are air-drying materials applied as liquid in the field. The paint system contains several products such as primers, emulsions, enamels, opaque stains, sealers, fillers, and other materials used as prime, intermediate or finish coats. Unlike paints, many coatings do not contain pigments and may not harden completely. Special coatings are thick and with high performance.

The main purposes of applying paints to a surface are protection, decoration, or to serve a particular function such as weatherproofing, etc. Paints are liquid materials that could be applied by brush, roller, or spray. Paints are composed of pigments, solvent, and binders. Most paints are described according to the solvent used, which could be alkyd, latex, oil, oleoresinous, rubber, or urethane. For a professional paint job, it is required to select the correct paint, prepare the surface, and apply the paint accurately.
