Thanks for the replies.
I have seen a thing called a plasters hawk at bunnies...but my question is - what do you do with it?
So far most of the walls look decent, and I have managed to just lay some plaster over the old joins - obviously never prep'd properly. I got some Gyprock Multi Purpose compound from Bunnies on the advice of a carpenter doing a shop refit at the building where I work. Got a truck load of plaster offcuts off him too
I haven't had a decent look at the loungeroom walls yet, but obviously I wouldn't mind making a fairly decent job of it if it requires a bit of fiddling.
Will look out for your tutorial, thanks
