Bob and all:
The most recent "timber framing" magazine Issue # 107 has an article titled "Timber Framing for the Homestead". In this article which shows a timber frame home built in the old style of fully exposed frame inside and out, built here in MA, on the western side of the state.

The infill which was a 8" thick block called Safecrete, originally a Swedish invention. Which was covered inside and out with a lime plaster.

He says about the inside covering of the blocks:

"Unlike stuccos of cement, lime plaster moves with the seasonal movement of the frame and does not crack or work free from the block [infill]. (There is no spline at the masonary-to-wood seams). Unlike stucco, lime plaster does not trap moisture beneath its surface. Also, being highly alkaline, it's resistant to mold and mildew."

He does not say anything specific about the exact make up of the outside surface other than both surfaces were covered with lime plaster.

This would seem like a solution to your idea to have the frame show inside and out.

I would suggest you purchase this edition of the magazine and read the article. Also to maybe contact the writer and get some input from him about how it's standing up to the weather here in New England.
