Might add keep the floor and furnishings protected until you know nothing is going to drip or fall from the ceiling.
Did a small mudroom ceiling once. Thought it was a quick, small job so just drag a plastic drop around to catch the splatter on a popcorn ceiling since I was using a 3/4" sleeve. It was just a few drops that had dripped and a little popcorn material that dropped after I moved the plastic. This was a painted concrete floor. Then the lady ho got a little fussy and got to walking all over it making it look twice as bad while giving me down the road. " I used to paint...I can't believe you did not cover everything.." It was very humbling experience. She didn't even want me to finish the cuting in. I made a mistake but enough was enough!
$200 to her and a sincere apology and I was out of there before it got really ugly.
