I have moved into my place in punggol for about 20 months. Quite a few months back, we suddenly realized that there was spots and patches on our ceiling in the master bedroom and the one next to it. We thought it was pipe leakage or something. But it was not damp and could be wiped off with cloth. But as the month progress, it became worse and spread through the whole ceiling of the 2 rooms. We are not sure if this is due to dust trapped or moulds or leakage. My ceiling looks like that now.
Anyone knows whats wrong?? Looks horrible!! Should I just paint over it?
