I have soon got to plasterboard by loft and am in the process of deciding how to finish it.
I have watched quote a few videos now on how to tape and fill a plasterboard wall.
And again a few on how to plaster (skim) a new wall.

what i can't seem to find an answer to anywhere is.
whats to stop me buying normal flat sheets of plasterboard and using something like polyfiller or a flexible joint compound or even silicon sealant/ decorators caulk on the joins ?

I know there must be a reason otherwise trades wouldn't exist that perform both of these techniques.
i'm just struggling with my google-fu tonight. I'm assuming it has something to do with the finish cracking ???
