I get overspray everywhere when I was painting. I was amazed at where I got it sometimes.
I'm thinking of grabbing one of those white painters coveralls next time I'm at Lowe's as I can expect I picked up a lot of it along the way.
I'm hoping some of it that landed off the drop clothes will sweep up, especially since a lot was picked up by my shoes when drying... We'll see if I now have a larger square imprint on the ground. I've had smaller overspray spots left from previous spots where the overspray left cardboard laydowns.
