2058772 9014894 PCTABS00002 The invention relates to a electrostatic spray apparatus, including a hood (11). The hood (11) defines a top region (11a) with a depending skirt (11b-e) and comprises first and second hood elements, either or both of which may comprise moulded shells, with an electrode sandwiched therebetween. The electrode extends over said top region (11a) and down the skirt (11b-e) to terminate short of the lower regions of the skirt (11b-e). The hood (11) is so constructed that, other than at the lowermost regions of the skirt (11b-e), said hood (11) does not have any junction of its planer surfaces having a radius less than one hundred and fifty millimetres. The hood has an opening (17) in its top region through which an electrostatic spray head (18, 19) is entered into the hood (11), the electrode presents a connection (28) for an electrical supply and the potential applied to the spray head (18, 19) is substantially the same as that applied to the electrode.
