We're having cork tiling put down (6mm thick), floorboards seem in pretty good shape but there are a few wide-ish gaps 3-4mm and I can't guarantee that all the edges are the same height so I wouldn't want any unevenness of the floorboards to start showing through the cork.
Should I put a layer of ply down first, screwed countersunkenly to the boards? How thick a ply, and how big/expensive a job is this?
