Hi -- I'm here for the first time! I help manage a 72-seat theatre in a town of less than 2000 people. It's a black box theatre, used mainly for one play a year, movies once a week, live concerts once a month or so, and various community events. The whole place is black except for the stage floor, which is sand-coloured. This is where my question comes in: the floor is original (1983) and has very thin sisal laid all over it. We have been painting it every few years, but the person who did that has left and I don't know what kind of paint to use! Any ideas?
