Mostly I am working in lived in homes, it’s great when you have and empty house to decorate but that’s not very often the situation. So, it’s important to have the room cleared as much as possible and get those dust sheets down covering all surfaces including the bed!
Clean and good quality dust sheets are alway used.
I move the heavy furniture to the centre of the room so I can work round and be able to reach the middle of the ceiling with an extended poll.
There, job done.
