Sounds interesting if I can avoid paying a plasterer. Wouldnt the taped
joins show when you paint over them? Can you give me some more deatils
of what tape and filler please.

No, the taped joins do not show (if you do it right). The edges of the
plasterboard are tapered in so that when you have filled it, you end up
with a totally flat surface.

The tape & filler are specially designed for jointing plasterboard...
called something obvious like "plasterboard jointing tape" and
"plasterboard filler".
