hi all!! i pricing a job at the mo and wondered the best way of going about plastering around a arch window reveal. the wall is currently a bare brick wall with a arched window in, i was going to just hardwall the wall including the reveal with no beads and then nail a thin coat plastic arch bead and skim with multi. is this the way or should a be beading the window before i hardwall it?? ?? blah blah blah hope this makes sense, thanks for any advice......
