[Cob] cob on earthbag

[Michael Blaha]

I have had some luck covering the bags with clay slip for temporary UV 
protection.
The slip would help the cob adhere too.
Pats right about filling the indentations first.  Cob / plaster keys 
right in to the space between earthbag lifts.
Cob evens it out and makes it appear to be a cob wall. 
Then the finish plaster glides on.

I've tried chicken wire and cement/lime plaster over stem wall earthbags.
Concrete cracks. It works pretty well  - so far. 

I have tried papercrete (PC) on some stem walls. 
The bags close to the floor / ground got moldy ( Charmaine said it would). 
I ended up removing most of it and used lime and earth plaster as a 
replacement.

Papercrete protected the bags from elements though.  I would try this 
again for outdoor walls. 
Moss could be encouraged with some yogurt and moss bits spread on PC. 
Making a green  / mossy earthbag wall.

Bags are neat because they don't require as much attention to the mix; 
they are modular; and they pack real tight - becoming rammed earth strong.
