Hi Reddit,I live in an apartment in a humid location. But I can't explain how it. I was wondering if anyone know's what this is? i previously had it and painted over it - to no affect as it returned in a matter of months. The colour of the paint as also a dull yellow. Some black spots have appeared too - which i suspect is fungus.Could it be leaking from the apartment above me?Any suggestions? many thanks in advancehttps://imgur.com/a/6nrWiV8Edit: Laguage. via /r/DIY https://ift.tt/2JSCHZl
