[Cob] Lime putty on cob and adobe.

[Ron Becker]

Hello Shody, thanks for the responce. In a workshop I attended put on  
by Carole Crews in Toas we put the lime and cob mix right on the wall.  
It set up nicely but the cob allowed us to put it on a little too thick  
and we got some cracking. But I see your point about the ph thing where  
acid soils are concerned. In the southwest the soil if often pretty  
alkaline. So it wasn't much of an issure I guess. But we did discuss  
adding cob or adobe mud to the first coat to help with adhesion. We  
also added paper pulp. The combination of cob and pulp made the lime  
very buttery feeling under the trowel and it adhered well.



Those who question global warming have a financial or emotional  
interest in the status quo.
