Plastering and painting works are done using plaster of paris on walls. This is required so that the ups and downs on the surfaces are removed or hidden. Also at times they are used to close cracks on the walls. Painting is done to add color to the room where it is done. Though at times it is simple and in white based on the need, they can also be colourful and textured to give life to the occupants of the room. Innovative ideas and color also give soothing environment in the room.
