Hi there - so I am having the balcony flooring replaced on my two storey victorian terrace house as unfortunately it had become rotten. To do this of course they had to take all the wrought iron off. It occurred to me that maybe while it's off it might be a good opportunity to have it painted - as I suspect it's easier to do when it's off the balony than on. I have a painter - but I'm not sure he has experience with doing this - so I wanted to ask what is necessary to do this. The old paint is white and it's ancient but doesn't really look rusty or anything - just old and perhaps dirty and a maybe a bit flaky. Does he need to sand it all back/off or can he just paint over it after getting any flaky paint off. Thanks for letting me know. Also - what kind of paint and how many coats would be required and how long would it take to dry. He may know that - but I thought I'd check so I am informed of how it's done. Many thanks.
