I used up the last of my workable cement mix yesterday and only covered a little more than half of one short wall. By my estimates in order to daub the entire cabin this way would require an additional 800 lbs of dry cement mix. Not very encouraging.
On the interior I have been experimenting with canned spray foam insulation. I bought three cans and sealed up part of two walls with it. I know this is terribly unauthentic material but something tells me if Daniel Boone could have gotten his hands on this stuff he would have been on it like flies on honey. The color is not great and the bead can be very uneven.
I put some of this on Thursday evening and trimmed it up Yesterday morning. Once it has been trimmed and or sanded it will take stain.
I did a quick test with some stain to see what it would look like and I have to say for reasons of time and economy this will probably be the way I go to finish sealing the cabin. At least temporarily for the winter. I may still panel the interior with barn wood eventually and I may still mud the exterior someday but for now I'm going to concentrate on sealing up the interior with this stuff.
