Cob: Re: earth floors

[Carla Kennedy]

Hi Paul,
Very interesting principle.  Thank you.  Would that apply as well to 
plasters for cob walls?  I read somewhere that you can use a harder, shinier 
plaster mix for kitchen and bathroom walls.  Would that be more likely to 
crack or peel? (That's basically what I understand delaminate to mean.)
