currently I have a wall that contains a door recess of about 8" deep. I need to plasterboard the wall and the recess. Clarelr where the wall joins the recess there is a 90 degree corner which I will have to but up the plasterboard. As both wall and recess will be dabbed and doted, do I need to put wood behind the 90 degree corner to support it.
If not, what do I screw the angle bead into ?
