Method and apparatus to deliver a fluid mixture

A mixing and dispensing apparatus comprising:

• a) a flow path comprising at least two conduits, at least a portion of each of which is flexible, each conduit having an inlet end connectable to a source of fluid and an exit end;
• b) at least one peristaltic pump operatively connected to the flexible portions;
• c) the flow path further comprising a mixer downstream from the exit ends and in fluid communication therewith;
• d) a discharge mechanism comprising a discharge nozzle downstream from the mixer and in fluid communication therewith whereby the discharge nozzle comprises a portion of the flow path and a hand grip portion wherein the hand grip portion is useable to direct the discharge nozzle at a target surface whereby the fluids, once mixed, may be applied to the target surface;
• e) a first actuator operatively connected to the at least one peristaltic pump, and,
• f) a gas flow line exterior to the flow path and having an inlet end connectable with a source of pressurized gas and clearance nozzle at an outlet end, and a second actuator is operable to cause gas to flow through the gas flow line and out the clearance nozzle whereby the target surface may be cleaned before application of the mixed fluid.
