Hi all, I need help please. I'm going to be making my own lime putty plaster for an exterior application over old painted "cinder blocks". It's a big project and I don't want to screw it up too badly (3 buildings worth min.) My main question is this: what are proportions for an application that could survive in new england? It is not a structural app, but I don't want it to wash off as my first attempt did. Can I add clay/dirt/ash for color? Secondarily, I'll also be working with half timbers cut from the property...how, if at all, can I get this plaster to "stick" to both the cinderblock and the timber. (I also have timber framed windows and had a B**** of a time repairing and filling gaps between the timber and the existing render. End all result was less than stellar and painfully time consuming (kept staining timber). Any help would be greatly appreciated. thanks!
