Floor gypsum for wall?

[jonasob]

Is there any possibility to use floor gypsum as wall gypsum? I have a small amount of floor gypsum left and have more walls than floors to build

Heavy, labor-intensive, expensive, and no beveled edges for joint filling, so no, I would have tried to exchange them at the lumberyard for regular gypsum instead.
