A few thousand years, before the dawn of history when man was only a cave dweller, he painted his rock shelters to express and satisfy his aesthetic sensitivity and creative urge. These walls served the purpose of recording animals, hunting and daily life in the civilization. In today's context, apart from serving its purpose of carrying information, a wall painting covers multiple functions like - defining and decorating a space, branding or artistic expression and public expression through community gatherings. For instance, a wall painting was created within Facebook's office in India, they are being done on the Tulsi pipe road in Mumbai to beautify it, or they are designed to add to the exotic interiors of restaurants.

In this section we shall see how a wall is painted for an indoor space. Before we trace the process let us glance through its history.
