My first attempt at rendering part of a wall (to repair) it went fairly well, but unfortunately I have added too much in a few places.
It is now totally dry and rock hard.
What is the best way to sand it down to get it smooth. I know I should have done it before it set fully but I didn't. I had thought it might look OK when painted but unfortunately now i need to get it flat.
