These are some pics of a flat we had to plaster last December. We decided to use bonding as it was to cold to knock up s/c.All the old plaster came off the wall in sheets as it had not adhered to the brick work. We also had to leave the coving on and the skirts,which acted as our "datums" for our wooden dabs . As you can see we sealed the walls as we went along (sbr) and formed the dabs into screeds. We did all the screeds and then filled them inbetween some times with one coat and some with two and floated and devilled them all up then skimmed it out..
