Heres a great answer to your question that I got from Andy deGruchy, the owner of LimeWorks.us. He's the guy that I got my sprayer from and he sells tons of Natural Hydraulic Lime on the East Coast. Hi Andrew, I have found that to have the oomph you need to push the sanded lime material you need at least 24 cfm (cubic feet of air per minute)at 90 p.s.i. continuously. So if you get a 90 psi pancake compressor- sure it puts out that psi pressure but peters out in no time because it does not have the volume of air per minute to keep going and won’t spray sanded stucco without frustration. In order to not have any question regarding having enough volume of air so you can keep working all day long I get the tow behind 85 cfm (if they have them that small) or 125 cfm air compressor (which is more typical) from a rental place.

I think you'll nee to make adjustments based on the type of plaster you're spraying and the thickness at which it is mixed. In general you should mix the plaster as if you were going to hand apply it. You don't want to add too much water as that will weaken the plaster. You will need a big compressor so that the pressure can stay high without the compressor cycling on and off all the time. Good question Charles.

There are several articles on my blog about the advantages and disadvantages of plaster types. It often comes down to user preference. I hope you find some input in the blog to help you decide.

I've read so many different opinions :). What are the reasons for choosing either earth or lime plaster?

I think that might be best. Everything I have read in recent months points towards a mud plaster beneath a lime plaster as a bad combination. If you can remove the plaster all the way down and build it back up, that's probably the best fix, albeit not the easiest. You may want to get a professional to help you. Hi Ruth.

First we used a mud plaster coat [with lime putty added] then the lime plaster. I over wet cured the first 2 walls and I think that's what caused the plaster to fail. Now I need to repair the walls. From your info should I just remove all remaining mud and lime and startover with spraying up lime plaster coats? I'm lousy at chemistry and the lime info is hard for me to understand.

The spraying definitely sounds like a better way to go, albeit not quite as social an activity as packing mud side by side with your friends and neighbors.
