Thanks ! Great12


someone told me the upper apartment floor maybe leaking due that is y the lower apartment celing is black with spots. Is this the cause also. I am just wondering how could the uppor appartment floor leak? (very absurd )

Thanks once again.

I also had mould appearing on the ceiling. I cleaned it off with bleach and painted with Dulux Gold which inhibits mould growth. I also invested in a dehumidifier and the problem stopped.

its due to high rates humidity and poor ventilation. advise not to clean it with wet stuff...


repainting will do, and always secure ventilation by using dehumidifier every after using air-condition.

You will need to kill the mould before painting, that's why I used bleach. This was over a year ago and the problem has not returned.
