Hi
New here and hoping someone might be able to give me an idea what's going on ...
We have recently moved into what used to be my grandmother's old bungalow. She passed away in 2008 and the bungalow has been uninhabited ever since, although we've been doing extensive renovations over the past seven years.
Previously (presumably over the course of several years), water had been leaking in around the chimney; we had a roofer install some flashing where there hadn't been any around the top and sides of the chimney. Where the water had been leaking and making the plaster beneath damp, there had been mould on the bedroom / kitchen side of the ceiling near the chimney breast.
These were cleaned with fungicidal wash, painted with two coats of stain-block paint (can't recall the make, but could probably find out) before the roofer came in last year, so during some bad weather water staining had made it through. So again, after he'd been and once it was dry we cleaned it, applied two coats of the same stain-block paint, and then two coats of kitchen / bathroom emulsion.
Despite this, even before we moved in, there seemed to be a regular sheen of moisture where that stain-block paint had been applied, on the kitchen side of the chimney, even if it hadn't rained for weeks.
During this past summer, even when it hadn't rained for weeks, we have on a few random occasions seen clear droplets of yellow liquid on the ceiling on the bedroom-side of the chimney breast, where that paint had been applied; when wiped off, it does not stain. Now my wife has just messaged me to say she's seen the same on the kitchen side, which is the first time I'm aware of that happening.
The droplets just seem to appear ... we don't notice regular dripping or anything like that which might indicate problematic quantities of water above
I will check tonight when I get home, but each time this has happened since the flashing was applied around the top of the chimney, the plasterboard immediately above the affected area has not been obviously wet or even damp. I'm mystified ... unless there was some issue with the paint, I believe my Dad had had it for some time ... it's just odd that these droplets only seem to occur where that stain-block paint has been applied.
Actually, one other potential factor: my Dad sprayed some expanding polyurethane foam between the chimney and the adjacent joist a couple of years ago. Last I looked it was not exhibiting any obvious sign of degradation.
Does anyone here have any ideas what might be causing this, please ... ? As I said, I'm mystified but we need to sort it, as on the bedroom side the droplets could affect electrical equipment ...
Edit: I should mention that, while my eldest son does smoke, he is not permitted to do so indoors. No-one else in the household smokes
