fixing 6mm Marmox Boards

[Telf]

Im due to start a job in a couple of days and im fixing 6mm Marmox boards on top of 15mm WBP Plywood which will be screwed down on top of 22mm Weyroc.

The Question is... do i need to lay with flexible adhesive or can i just screw them down with marmox washers?

One person said i only need to screw every 300mm but a website that i was looking at for prices said you can't screw 6mm down it has to be put down with flexible adhesive. So I thought i was all sorted now im stuck what to do again.

What would everyone else do or does any one no the answer?
