Drywall contractor: About a week. We need to hang it, then apply the first coat of magumpus. I need to come back a couple days later and apply another coat of magumpus. Then sand the magumpus and paint the walls.
Customer: What are you gonna do about the floor? It slopes down toward the center of the room.
Contractor: Well, I need to mix up some magumpus, pour it on the floor to make it level, then put a layer of plywood over the floor.
