Hi all, just wondering if anyone can give some advice on my current problem. I'm renovating and have removed an old air vent from the wall in one of the bedrooms. Cut some Gyprock to fit, but I can't get it to sit flush with existing plasterboard, it sits out from the main wall by about 3mm.
Directly behind the air vent, in the wall cavity, is a wooden beam. Naturally it sits flush behind the existing plaster/wall. The existing plaster and my patchup piece are the same depth. There is nothing stuck to the beam to make the new plaster sit out, it just does.
By this point, you've probably worked out I don't know a great deal . I guess what I want to know is, should I attack the beam somehow to make the new gyprock piece sit into the hole further, or can I do something to the gyprock once it is positioned in the space to make it flush, i.e. sand the **** out of it.
As I said, not much idea really, patience is appreciated
