The objective of this study was to design and develop a wall painting equipment to gradually replace human laborand increase labor productivity. The study was conducted to design and fabricate wall painting machine with a flow of 54 liters per hour. Based on the theoretical calculation, application of graphic design software, experimentation, and the principle of working, the parts of wall painting machine were designed and fabricated. Specially, based on the theories of general hydraulics and machine design, the automatic paint pumpingsystem, a type of peristaltic pump, was designed to be suitable for painting solution and painting system. The project has successfully fabricated the wall painting machine with the capacity of 300 m2 per hour, 3-4 times higher than that of the manual painting equipment with cheap manufacturing cost. The quality of painting surface did not depend on the skill of painters In addition, the system is quite compact, easy to move at construction place.
