There is shown apparatus 1 for underwater painting of a substrate 9, comprising a tubular shield 2 having a closed end 3 and an open end 4, and a paint supply device 7 and a compressed air inlet 5. The air inlet 5 passes into a chamber formed between the end 3 and a perforated baffle plate 6 which serves to provide a uniform stream of air under pressure to the open end 4 for displacing water from the substrate 9, which can then be painted using a circular ring of paint issuing from a spray tip 11 of the device 7. The position of the shield can be adjusted using adjustable casters 14, or electronically (means not shown). |
