Re: Restore plaster walls after fire
I'm a historic preservation carpenter/foreman. We work on old houses, and last summer we restored a 1817 house, which, unfortunately entailed gutting the entire first floor of the original core structure. The owners being very preservation-minded to begin with, (the house is in a village that is a National Landmark Historic District), were open to re-plastering one room with the original three-coat lime finish, on the salvaged split heart pine lath. The framing was all replaced, but the room appears as originally. We obtained all of the materials (except the sand) from Virginia Lime Works. It's definitely a more labor-intensive way to go. We used a 1/4" crown stapler to fasten the lath. It's much better than trying to re-nail the brittle lath of 200 years. We found the most time-consuming aspect was filtering in the horsehair at a slow uniform rate. If it's wadded and clumped, it isn't doing anything. There are some tutorials on Youtube that may be helpful, search "Lime Plaster" and Va Lime Works.
So, one room was done as an example of a museum-quality restoration, patched areas on the exterior brick walls were also done with lime/horsehair, but the remainder of the house was done with blueboard and two-coat plaster, for speed and economy. It comes out looking like this:
Remove not the ancient landmark, which your fathers have set.
