[Cob] plastering

[sly at riseup.net]

Hello,

I'm about to do a workshop on light clay, cob and then finishing with
plaster.   My question is about drying times.  Can I do each layer the
next day or do I need to make sure each layer is completely dry before
applying the next.  The light clay will be stuffed in the walls and then
we will cob over that after putting up a metal mesh and then we will put a
finish sand clay plaster.

Thanks,
Sarah
