I don't think you do. The only thing I can think of is to hang a sheet of drywall or plywood--both come in sheets 4' x 8'--on the wall and paint that. Both are heavy, so you'd have to put holes in the walls to hang them. Maybe you could just prop a sheet of one of them against the wall, making sure it's leaning enough not to fall over because if it did it could damage people and things.

No.

I'm 16 and my family is moving into a new house. The house was just built and we're renting it, so we can't exactly paint the walls. However, I wanted to paint my room in black chalkboard paint so I can draw on the walls with chalk. But since I cannot actually spent the walls in my room, I was wondering if there's anyway to put something up or down so I can paint it and it'd be as if nothing is abnormal but easily removed or taken off for if we move again.
