Abstract: There is provided a spray unit for a remotely operable spray apparatus. The spray unit is configured to spray a material having first and second material components. The spray unit comprises a first material inlet for receiving the first material component, a second material inlet for receiving the second material component, and a spray component comprising a mixing chamber and a spray orifice. The spray component is movable between a spraying position in which the mixing chamber is in communication with the first and second material inlets such that the first and second material components enter the mixing chamber and are sprayed via the spray orifice, and a non-spraying position in which the mixing chamber is closed from the first and second material inlets. The spray unit further includes a pneumatic actuator operable to move the spray component between the spraying position and the non-spraying position, and a remotely operable electric actuator arranged to control operation of the pneumatic actuator.
