Air-assisted, low pressure spray equipment having an improved spray nozzle including a caulking gun having a carriage adapted to receive cartridges having a nozzle, rams mounted on the caulking gun for engaging each cartridge to dispense a liquid from the nozzle, a trigger mechanism for advancing the rams into operative engagement with each cartridge; a static mixer having an inlet port for receiving a liquid component from the nozzle of each cartridge and having an optional spray tip for introducing the mixed liquid components into an atomizing zone; a static mixer shroud encasing the static mixer and an optional spray section having inlet ports for receiving pressurized air and outlet ports for introducing air into the atomizing zone. The spray tip passes through an orifice in the spray section such that the mixed liquid components are introduced into the atomizing zone. The equipment is useful for spraying a two-component composition.
