As is well known, in the shipbuilding industry, due to its nature, there are limitations in automation and mechanization of painting work, so it is mainly done manually by skilled workers, and accordingly, it is required to secure skilled painters.

For example, it is very important to paint the paint exactly to the required thickness. If the paint is applied too thickly, the consumption of the paint increases, and if the paint is applied too thinly, the ship may be corroded and reworked during quality inspection, resulting in additional costs. this will happen

On the other hand, spray painting training is also conducted at the actual yard to increase the proficiency of painting work. Waste of paint, long-term training impossible due to toxic paint, limitation of practice guidance while wearing a gas mask, lack of supply and supply of practice subjects, coating Actual spray painting training is limited due to problems such as increased waiting time for training due to drying.
