I am undertaking my garage conversion and looking for some advice. All external walls (including the new one in place of the garage door) are cavity walls. However, the two 'columns' either-side of the garage door (and supporting the lintel) are of solid double-brick thickness construction (i.e. no cavity). There is a DPC however.
Can my plasterer plaster straight onto this section of wall? Or will this lead to penetrating damp and some for of 'tanking' should be undertaken?
