Its been a while since i did roughcasting and just wanted to ask a question; why is lime used in the mix? Do i NEED to use it or can i do without it?
Cant remember exactly; i used it in my roughcast mix before, but have forgotten why. Is it to do with the age of the building, (my house is 70 years old), breathability on the wall or to help it all bind better? Thanks in advance.
