Paints are a mixture of pigments and adhesives that are generally available in liquid form. Different types of paints and their application in the building are discussed. Paints form a solid layer when applied to the surface. The film protects the surface from many hazards such as corrosion, weathering, chemical attacks, and so on. Wooden or metal structures can extend their life by covering with paint. Not only protective paints, but they also give the surface a beautiful look. Therefore, paints play a major role in construction work and projects.
