Because people use aircon everyday with very low temperature and the condensation causes the external walls to be very wet

In Bukit Panjang there are a lot of HDBs like that not just in Seng Kang

That is true but I am talking about the problems of HDB flats, one if the reasons is aircon too cold in the room, as a result the wall in the other room or external wall get wet. 





When the temperature in one room is 21 degree while the other room is 32 degree, it will cause the water vapour in the air of the hotter room to accumulate to the wall. This is similar to the case when you grab a can of coke or beer from your fridge you see water stains all over the can due to condensation. So dunt just blame the weather the residents who use aircon on daily basis are to be blamed or they are simply ignorant

The condos at Bukit Timah Hill need to be repainted every 4-5 years owing to the unsightly mold formation. The humidity of the hill and forest reserve are contributory factors.

Humidity is one reason but aircon condensation is the other reason

My friend uses a CPAP machine as he has sleep apnoea. There is condensation inside the unit owing to him sleeping in an aircon bedroom exposed to the afternoon sun while he is at work in the daytime.

HDB can only repaint the external wall but you have to fix the condensation problem to your walls at home as it will turn your walls mouldy sooner or later.

Moisture attracts mold.

But not everyone switches on aircon round the clock leh.
It is not that simple.
You come to older estate, you won’t see mould issue so common lah.

The real reason is newer estate(maximise profit) is building too close to each other. Lack of direct sunlight to dry up the wall.

The designer also never includes humid factor.

The subcontractors are using low quality paint to maximise profit?

Maybe they should erect a number of mega fans to blow  the HDB external walls every night.

US and British spelling.
Mould is British spelling.

Bullshxt lah.
Mould issue happens sometimes it is due to hollow wall, rain water is trapped in it, cannot dry up in time. You need to solve the root cause.

这只是治标不治本lah.

If that is the case all the HDB’s external walls will turn black not just in Seng Kang

I've seen this happen in my block too, and it gets worse during the rainy season. The trapped moisture makes it easy for mould to grow, especially on older HDB walls. Mould Testing can help check how serious the problem is and if the air quality is affected. Some neighbours tried scrubbing it off, but it keeps coming back unless the underlying moisture issue is fixed properly.

Hv to use anti mould paint. Some parts of wall will still need to repaint 7 to 8 yrs
