I have a 1894 house with a stone/rock wall (limestone I think). The foundation is in decent shape for the most part but I would like to parge the exterior visible portion to give it a more modern look and to also make it easier to maintain. Currently each fall I go around and try to seal up any little cracks that developed through the year.
Anyway my plan is to dig down about 6 inches around the exterior. Then attach some diamond mesh to the rock wall. Use the first coat to fill to the level of the mesh, then skim coat that layer to give it a smooth look.
1.) What kind of cement/mortor to use for parging?
2.) Can anyone offer a better suggestion on how to go about this?
I should mention too that part of the reason for doing this is that with a couple layers of siding (the most recent is LP smart siding) it sticks out a 1-2 inches over the foundation. I know I can't parge nearly that thick, but having a good 1/2" of parging would help narrow that gap.
Any input is appreciated.
