[Cob] cracks in plasterJill Hogan jill.hogan at mat.org.zaWed Sep 17 13:00:38 CDT 2008
Hi Bob Wemix all the sand clay and lime together, no presoaking and we mix it with our feet on tarps like we make cob. Seems to work best Regards MAT 023 625 1533 www.mat.org.za We are sponsored by Cape Lime, Robertson. ----- Original Message ----- From: Bob Smolen To: coblist at deatech.com Sent: Tuesday, September 16, 2008 9:41 PM Subject: [Cob] cracks in plaster Thanks Jill and Ron for your thoughtful comments. I reinspected the wall and there are only a couple of very minor cracks in the last lime/sand only layer. I am pleased. The earlier coatings were probably too clay rich as you suggest. I will experiment with a less clay mixture. I mix the lime and sand and clay at the same time. Is it necessary to soak the lime in water for days before mixing. My last coating seem ok so I believe presoak is not necessary. Can you comment on how you have done your plaster mix?
