Hi All, I wonder if I could seek some advice about the outside cement render(horrid but can't afford complete render in lime) on our cob and stone property. I noticed a couple of hair line cracks and one spot where the render is bubbled and raised. What can I do to protect the property for the mean time until summer (will hack off loose render and re -render bubbled patch with lime in summer)?- if any one could advise me please, that would be great. This has probably been covered already so apologies if this is the case.
