So I went to this job today all had been pre plasterboarded and beading by the customer as he was "only trying to help" anyway so I get there and the whole job is totally botched the board is not even at the top the beading is not level and where two bits join theres a gap between the beads but nothing behind it so how can I fill this gap plus a bit of the plaster board has snapped so the gaps bigger thinking either getting some plastic beading thats bigger to cover it up any ideas....Theres no board or anything behind the gap...The screws were all sticking out the board.........trying to help trying to save money more like.
