Re: SB: Stucco ingredient volume

[Charmaine R Taylor <tms@northcoast.com>]

HI

I'm completely at a loss to figure out how much sand, lime, OPC to order up for my stucco session in the spring.   
5)  Using Charmaines stucco formula of 1:2:9 (OPC, lime, sand) then I have
basically 8% OPC, 17 % lime, 75% sand and water unknown.  

HI George... 1:2:6 is the NLA formula NOT MINE for stucco of lime.

I like pure lime for plastering...but if you follow theirs I think you will still need LESS than 20 bags as lime gives more  actual volume per bag.

However I have not ordered that much lime for ANY job so I am hoping Harry Francis will answer this if he knows the calcs.


The lime isn't swelling, it just adds water to become a soft putty, and I believe you would need to add theM DRY together ( OPC and hydrated lime) because the cement will begin to set as soon as wetted.

Again the NLA has specific directions, I believe, on mixing..I will check this out and get back to you.

the NLA 1:2 ratio is by volume DRY as I recall. so you wont get the advantage of soaking the lime as you would with a pure lime plaster.

any reason you want to add the cement? faster set for winter??
