[Cob] Earthen plaster & CEILINGS

[ocean]

Kiko has found the easiest way to adhere earthen plasters to a stud 
wall is on top of standard drywall sheathing - the mud sticks very well 
to the cardboard surface of the drywall.  We've also used the extruded 
metal lathe (intended for stucco applications) over wooden sheathing.  
If you apply drywall to the ceiling, the mud should stick well there 
too.

(Kiko doesn't think mud plasters will stick as well to wooden lathe, 
due to the high expansion of clay plasters.)
