I fitted a new DG window into the drylined wall last weekend and finished
the reveals last night, complete with corner beads for reinforcement. I had
planned to feather the plaster from the beads onto the mirror-like finish i
had achieved previously on the plasterboard dry lining - instead i got an
awful drawn out mess at the edges, covering 50% of the wall in an attempt to
feather out smoothly (lots of water, panic sponging and bad language).

I'm no expert in this area but board jointing mix is reputed to be good for
feathering.
