Painting and Polishing
Paint preserves, protects and decorates surfaces and enables them to be cleaned easily.

Types of paints:
There are seven types of paints, used commonly are :

Oil paints
These are the traditions type having a linseed oil medium. Finishes vary from flat to oil-gloss. Oil paints dry by evaporation of the solvent and by oxidation, synthetic paints have replaced them.

Synthetic paint
The medium for these is a chemical compound, one type being oil-modified alkyd resin. They have the advantage over oil paints in setting more quickly and offering greater durability where corrosion is a main concern. They also have better flow and are easier to apply.

Water paints
Known also as distempers they are used mainly on internal walls and ceilings and most of them give a flat finish. They have a drying oil or varnish medium emulsified in water. They are prepared on the site by adding water to make a paste. Emulsion paint has super ceded water paint.

Emulsion Paints
These are mostly used on wall surfaces. Oil bound distemper is a type of emulsion paint. An emulsion paint has the pigments and medium dispersed as small globules in water. Oil, synthetic resin and bitumen are the common mediums. Among different emulsion paints are alkyd, bitumen, polyvinyl acetate and styrene emulsion paints. The finish obtained is flat to egg shell gloss.

Cellulose Paints
They are mostly used as spray paints in car industry because they dry very quickly by evaporation of solvents. They are not satisfactory for general building work but can be used for furniture and fittings in houses.

Special paints
Among the many kinds are aluminum paints, bituminous paints, chlorinated rubber paints, fire-resistant paints, heat-resisting paints, fungicidal paints, texture paints etc., These are used for special applications and manufacturer’s instructions should be followed for thinning and applications of the required number of coats.
