[Cob] Using cob for filling gaps in wood

[howard at earthandstraw.com]

The first consideration is what you have for a foundation.  Will it carry the load that cob would be? ...or would a light clay/straw wall be more appropriate to stuff the stud walls with?

  Subject: [Cob] Using cob for filling gaps in wood


  Hi all,

  I recently inherited a cabin whose walls are made of rough-cut lumber
  planks, much of which still has open gaps between the planks so you
  can see the light of day through the wall, like a barn I suppose.
  Also the floors have gaps as well, like a porch/deck.

  I'm wondering if people think cob would be a reasonable solution for
  sealing up the gaps.  I'm hoping I can determine a good recipe with
  some tests, and then just go at it with some putty knives.  I guess if
  I need to use some plant fibers, I'll have to use something very
  finely ground; maybe even wheat paste?  Are there any special
  considerations for ensuring that the cob sticks well to the wood?

  I believe I have plenty of clay on site, but have not yet made any
  test recipes to confirm.

  An unexperienced and aspiring cobber,
  Gene
