Painting can be categorised in 2 parts - In-house painting is a five-step process. To begin with, you need to clean the walls and ceiling. Post that you need to apply a primer coat. Once the primer is dry, apply wall putty twice. Finally, apply the coat of paint chosen and then another coat to give it a rich and thick feel. The exterior painting process for a new house or building is a 3-step process. The painters apply primer first then once it is dry, apply the first coat of paint and then a second coat to finalize it. Exterior painting of any commercial or industrial building requires concrete planning. You must consider the business cycle and choose a time when there is minimum disruption to commercial and business activity. The important thing to take care of at the time of painting any commercial building is colour. The choice of colour should complement the brand and enhance it. Any colour shade that goes well with the business brand is a great choice. After initial painting and occupation of the house there is need of repainting later. Most experts suggest that walls of the houses need to be painted every 4 to 5 years. This depends on multiple factors such as climate or weather and the location where you stay. If there are any floods or any other natural disaster, the houses need to be rebuilt and repainting is also a necessity. Considering the pollution and humid weather in Mumbai, it becomes even more imperative to re-paint often. The simple steps in repainting are to wash the walls with water to clean all the dust. The washing needs to be done twice to ensure every corner is clean, and then let it dry for a day. Then comes the coating of primer on the entire wall and ceiling, especially the damaged areas, fill it to make it smooth. If there is colour change then the old paint needs to be scrapped off completely which might take time. Any painting work with equipment like rollers, sprays and pole brushes will help the painters finish the work on time and ensures a perfect finish.
