We have a fairly wide staircase, with a sharp curve in it (it doubles back on itself). The result is a drop from one side to the other of say 6 feet. There's also a gap in the middle which somebody could fall down. The ceiling is also pretty high, and to paint the wall on the 'downhill' side you need to be able to reach up around 15 feet. Any suggestions for a safe way of working, please? This is the staircase between the first and second floor, btw.
One thought was just to paint walls and ceiling in white and use a roller on a very long pole, But then we would have to continue that lack of colour right down to the hall, as there is no natural break.
