Wetting hardboard for under under new carpet. How wet?

[wanabechippie]

Hey.

Going to be laying new carpet over floorboards upstairs soon. Big gaps/nicks in boards so i'll be laying hardboard (or ply??) over the boards first.

I know the hardboard needs wetting before it goes down to prevent warping at a later date, but how wet are we talking? Damp sponge over? Garden hose? Overnight in the bath? Wrapped round a fat bloke in a sauna?

Cheers.

Just a would the weight of the underlay and carpet keep the hardboard flat.

How to do it and how much just under the table

But if its an occupied house just leave the boards for a few days to settle down before fixing.

After searching for the second time on here, I found the thread I was looking for prior to posting this thread.

Remembered something about wetting the HB but wasn't sure how much.
