Log burner finish?

#1
Hi all I need to render a big surround for a log burner it consists of engineered bricks, lintels and concrete blocks! Not sure of the best method? Has to be done in sand cement and lime but needs a smooth finish
Do I scratch coat it and then top coat in sand and cement and key the top coat and then pva and skim with multi finish?
Any suggestions please
