[Cob] frozen cob

[phil]

To be more specific, frozen cob mortar in a cordwood wall.

South facing wall took rain in a heavy wind, temp dropped to well below freezing and the cob has gone mushy/crumbly. Any ideas for a protective coating? I'm suggesting a simple lime plaster to the homeowner but would like more input.

Thanks,
