I've gotten some conflicting advice on which cement to use on an old chimney. I was told that I cannot use just any motar mix for chimney repair because I have an older chimney. In my current house I'd like to redo some of the exterior parts of the chimney above the roof, but in the house I'll be moving into at the end of the summer I have some repairs I'd like to do on the chimney that is inside the house (attic, etc). I have cement needed to repair anything in the firebox, but it didn't say anything about exterior use, or outside the firebox area.
This is what I bought, but have yet to use...
Type S Mortar Mix
Any thoughts?
