high pressure airless spraying has just become popular in China in recent years, but in foreign countries, high pressure airless spraying of interior and exterior wall emulsion paint has long been widely used. The specific construction method is to use a special high-pressure airless spraying machine to deliver the high-pressure paint to the spray gun through the high-pressure hose, and then release the pressure through the spray gun to form atomization, so as to form a smooth and dense coating on the wall surface
