Claims20
A spray applicator, comprising:
- an applicator body extending from a first end comprising a handle portion to a second end;
- a first spray assembly, comprising:
- a fluid mixing chamber connected to or within the applicator body and configured to independently receive fluids from a first source and a second source, the fluid mixing chamber comprising a first fluid inlet and a second fluid inlet, a fluid mixing passageway, and a fluid outlet to receive mixed fluid from the fluid mixing passageway;
- and
- a first spray nozzle structured and arranged to receive mixed fluid from the fluid outlet of the fluid mixing chamber, comprising a fluid inlet and a spray outlet positioned to direct a first liquid spray pattern external to the spray applicator;
- a second spray assembly comprising a fluid passageway and a second spray nozzle attached to the applicator body and positioned to direct a second liquid spray pattern into a first liquid spray pattern from the first nozzle;
- and
- a controller comprising an actuator mechanism and a trigger configured to control a flow rate of liquid from the first nozzle and/or from the second nozzle, wherein the trigger is located at or adjacent to the handle portion.
A method of manufacturing a spray applicator, comprising affixing a water spray assembly to a plural component spray gun comprising a plural component spray nozzle, wherein the water spray assembly comprises a water supply tube connected to a fluid input of a spray nozzle attached to the applicator body and positioned to direct a second liquid spray pattern into a first liquid spray pattern from the plural component spray nozzle of the plural component spray gun.
