Depends if you need cement or lime render. For cement, 6:1:1 is good.
For lime, 3:1 lime putty to sand is good. Dont use cement render on old
properties, mistake.

Lime putty is most economically made by dumping a bag of hydrated lime
into a bin, covering with water, and closing it up. Leave for a month
or so.
