I’m in the process of repairing a large natural stone wall, limestone. Around here , Milwaukee, they call it Lannon stone. On one side it was coated with stucco, half of which as fallen off. The idea is to get rid of all the stucco, repair, replace, and point the stones as needed.
My thought is to start with Quikrete premix mortar cement (#1136) which costs about $3.50 for 80#s for the inside repairs and use the same colored mortar for exterior pointing. The colored stuff runs at least twice as much.
The original wall was build in 1931 so the colored mortar lets me blend with the original mortar.
The #1136 is a type S mortar. I am thinking to soften it down a little for this limestone by adding lime. Am I nuts from reading too much restoration stuff about modern mortars breaking the stone?
Has any one done this kind of doctoring? Any thoughts?
Thanks

You're not nuts.
Search the forum for lime mortar or google as well.
There have been a few restorations here where lime mortars were used.
