Hence, 20 m² can be coated effortlessly per hour with a layer thickness of 200 µm using the Venturi Coating System. Apart from the Venturi spray gun, the use of the Venturi Coating Systems requires a compressed air source of 8 bar. The RepaCoat coating is supplied in a double cartridge with a special mixing spiral for the system.
