MDF is bent!

[attractivebrunette]

I wallpapered a very big MDF door 102cm x 232cm and left it overnight lying flat on two boxes either end.

I'm sure this has bent the MDF in the middle as there was nothing to support the middle

Can I rebend it by turning it over on the boxes and leaving it there another night so it re-bends back the other way?

Probably!

The moisture in the paste will have helped it warp, dampening the underside will help with returning it to a flat conditioned, though not guaranteed , timber batons fixed to rear are needed to help it remain flat and true.
