Gluing Cloud 9 underlay

[Ruggers]

I'm going to fit some cloud 9 cirrus 9mm underlay and was wondering apart from taping all the joints once down, is it recommended that I spray glue all the underlay to the floor, just the edges, or not at all?

I have wooden floor upstairs and bitumen covered concrete downstairs?

Staple the underlay to wooden floors, A little spray won't hurt on bitumen but not 100% necersary.

Yeh I've spoken to someone now but thanks for the reply and backing up what I was told elsewhere.
