Basically whether skimming or not (and my research shows this seems to

tape and jointing compound and you will not get cracking. Butt the non
tapered sides together and all you have to cover the Joint is the skim.

Have you ever tried to remove wallpaper from plasterboard which wasn't
skimmed?


Not to mention the damage that everyday knocks and bumps does to
an unskimmed plasterboard wall from about 3 feet downwards.

Builders just like to tape'n'seal'n'paint because they don't
have to pay an expensive plasterer, and it can be done with
semi-skilled people (=cheap).
