Our stage floor is in a terrible state, I don't think its been reskinned in over a decade. Its MDF so I'm putting a proposal together to pay for it to be reskinned. If we end up doing it in house (more than likely), I believe we need to prep the MDF before laying it down. Someone once suggested to me that the sheets needed to be painted on both sides to prime them, I'm guessing so that they expand before they're layed. Does anyone have any advice?
