Hi
Have had whole house replasted recently and turns out the guy was a cowboy. One of the problems we have been left with is damp patches on walls. Some patches appearing on interior walls and not by pipes so let’s assume it’s not caused from DPC or pipes etc.
The patch in the picture is the worst, it is on the chimney breast which was boarded and plastered. We have tried using zisner primer and whatever we do we keep getting this patch returning. Any thoughts on the cause (chimney is ventilated) and/or suggestions for treatment?
Thanks.
