[Strawbale] Mixing S Type Lime in a Mortar Mixer

[Debbie Johnson-Jackson]

Hello All,
	Does anyone have experience, proportions and/or pointers for mixing  
S Type lime in a mortar mixer?
We would like to mix and slake all the lime we will need to do our  
lime plastering. We have the room to make
the troughs to hold it, the big question my husband has is how much  
can be done in one mortar mixer load
and is it best to add water first then lime or visa versa?
	Thanks for the help,

			Debbie
