We are a small theatre group and rent a local community theatre for our performances. The facility owner does not allow any painting or nailing to the floor. The floor is a SHINY reddish hardwood surface which causes us problems. We are thinking of building our own modular floor which we can be put on top of the stage when we need. We are considering using cam locks for clamping the floor-pieces. Please advise on the materials and the techniques of building the floor.
