Cloud 9 underlay which way up?

[Odd Job]

Hope someone is still up tonight, as i'm having a fitter coming tomorrow.

Any one know if its brown side, or plastic side to the floorbaords with cloud 9 underlay

I have found 1 discussion when searching the net and they suggested brown paper facing up, but if they are wrong im stuck.

Also i have double sided tape to go on the floor, now im thiniking i may need a one sided to actually join the pieces on the top rather than underneath?

any tips?

Many thanks

Bit late to answer this but for reference - its writing side up so the floor looks like a giant advert for cloud 9
