Thanks folks! That's really helpful!! :)

I have recently taken on a venue that has a concrete stage floor, there are flush wooden battens every 30cm or so running upstage to downstage. We have a varied program of work, mostly receiving but includes dance and amateur musical theatre. For the dance we lay a soft underlay, wooden interlocking boards then vinyl on top, this is time consuming and takes up a lot of storage space when not in use. The sets brought in by companies can be screwed into the wooden battens but you have to get it in the right place. What I'd like to do is lay a more permanent wooden layer over the whole stage. My question is, what would be the best stage covering for my stage? Ply? Or something sturdier? How do I make sure this doesn't warp when painted for the first time? Thanks!
