have been tasked by client to lime plaster most of his old georgian house,never got anything plastered in my life, except me, need a bit of advice if poss. client has lime plaster everywhere and its cracked, popped, fallen off, uneven,looks bad. have chopped back to firm gripping plaster and exposed a lot of laths, filled in with new hairy lime plaster and replaced laths that were too bendy or missing. problem is that now the repair fill in plaster is at a level depth of about 6mm. which matches the depth of original lime plaster which is bumpy and cracked but firm, no way were 3 coats put on these walls and I can't paint over this until it is all sanded which given the hair in the lime plaster is not an option. have suggested to client that it might be possible to skim the walls with a medium lime plaster that will be about 8mm thick and allow me to get some sort of finish ready for clay paint, question, would this work? and how best to prepare old lime walls before i put the medium plaster on, any ideas.or have i got this all wrong.
