I have this building that will be storage in the back half, and sorta "she" shed in the front. But I've been thinking about painting the floor to make it a bit nicer. Should I get something like deck paint, or can regular wall paint work? Or is there a inexpensive (cheap) covering. I'm thinking on the "she shed" part to have a rag rug one day to go with the camp rockers and this cot I have in there. This is a long term work in progress.
