Interesting terminology. Yes, you can put plasterboard or drywall over existing plaster. However, are there any plumbing or electrical considerations? How will you trim corners, baseboards, doorways, etc ? Usually it is smarter to remove the old material before applying new. ps It is wise to remove all loose plaster, as it may release and lodge in the way while applying the new board. Of course, if the whole wall is loose, you have nothing to glue to, and trying to nail or screw plasterboard over plaster is often hopeless.
screw studs to the wall vertically and screw board to studs then finish plaster
