My sister has recently moved into a newly renovated 'barn'. The origianal external walls are 9 inch solid brickwork (some reds some Flettons). The Architect specified chemical dpc injection, 'Actis' multi layer insulation on external side with wood batten and finished with horizontal ship lap boarding, painted. Internally the walls were 'dot and dabbed' and plasterboard installed with skim coat finish. The problem is that since occupation there are saturated spots at every 'dot and dab' position. Is this moisture coming out of the brickwork, being drawn into the warm, or hygroscopic salts within the brickwork attracting moisture from the rooms as a 'wick' affect? The builder has suggested that the whole area be dry-lined internally.
Any suggestions?
