Fair enough, guess we can all only go on our own experiences.
Wooden floorboards, agreed never had an issue, just a couple with bowing on older boards. Only seen breakthrough on chipboard and only when it got damp, so I always advise better safe than sorry now.
Looking at the label it's Structural Ply (for use in Walls, Floors & Roofs) Adhesive is MUF+PF. Requires treatment for external use. It's getting used as a bath panel to tile.
All hilarious......... no need to place anything under your bath legs. The flooring itself spreads the load over existing floor joists., adding anything else would be pointless.
