Some more progress since last post. Painted all plastered surfaces with bare plaster paint, ended up buying a fresh tub and much easier to apply as had no bits. Even with all the time spent sanding and filling prior to painting, any minor defects are shown once its painted, so any filling and sanding again. Dry fitted all the lights to mark holes for fixtures, still need to do radiator,I have kept the measurements on a sheet of paper. Skirting board has been fitted in landing, sanding over fixing holes still needs doing. Internal corners scribed. Went with the mesh matting prior to plastering, instead of plasterboard. End of stair trimmer had grain end, so I glued and nailed a trim of wood to make it all neat. Didn't expect a good paint finish hence the reason for this.
