I had quite a long chat with the Sarissa people when I was at the Games Expo thing. Apparently the MDF squares do warp when one side is made overly wet, but sealing both sides helps prevent it.
What did surprise me is that, according to the chap I spoke to, MDF becomes pliable when heated. So, leave a warped board in the sun, or on a heat source, and its own weight will flatten it out.
Never heard that before.

I've never tried it because once you've got stuff glued to the top it seems a bit of a risk!
I would also resist the temptation to use an artificial heat source as MDF is choc full of nasty chemicals which overheating might liberate!

Do yourself a favour though and don't research the dangers of MDF or you'll be rebasing everything on something that won't embalm your lungs!

Never ever cut it with a proper breathing mask, even in small quantities, it is truly lethal stuff.
