IMO steam vacuum is waste of money. First step is to use conventional items - cif or vinegar/soda mix with some good physical brushing. If it doesn't work, try aggressive removers like bleach etc. if still doesn't work. Consider replacing a few tiles only. This might be the best course path without incurring too much cost and reaching the end goal.

There are other ideas for electricity savings too. IMO the main consumers are 1 - Air Cons > Fridges > Washing Machines > Heaters > Fans (Yeah! you will be surprised) > Computer/Laptops For Fridges - old Fridges tend to consume higher wattage too so better to change. Rather than Gas heaters which require new line set up simpler solution is to train to take cold water showers. Its proven to be good for you. If you really need hot water showers then install the lowest cost option. Also for aircons, the other option is to replace them with dehumidifiers and air coolers. They are of lower wattage the conventional aircon and require lower maintenance in the long run especially filter changes, checks and chemical washes etc. Fans too I think to make best use of wattage change to good solid brands like KDK and don't go for cheap option because for same wattage the experience is worse off. Computer/TV laptops you would be better with lower lighting of back panel that tends to drain your electricity if you are using these devices regularly for long hours.

A recent update. I got the HDB to come and inspect it. Their thinking is that the wall is not a main beam so not problematic. This is a wall consisting of several panels. So the bulge so to speak happens between the 2 panel joints. Their suggestion is that I install a carbon mesh between the joints using a contractor to reinforce the joints and then seal it with another layer. The process will involve breaking open the wall to see the defect, perhaps add carbon mesh and then seal it then paint it. He also told me that its pretty common in older flats but not so in prefab styled ones. He also added that it could be moisture related and that windows need to opened to keep humidity under control. So, I asked them if any contractor like Nippon paint would do it. Then they told me that you need an approved contractor but didn't know if Nippon paint had capability. So, I will be looking into a quotation soon.

Wouldn't plastering seal the bulge inside? I was thinking this portion of the wall needs to be sanded or something before plastering or re-sealing. I am comfortable doing white cements on the holes created by nails or chip offs on the wall. If it is plastering the entire wall, I may end up hiring the pros. Any idea if the painters will handle this or is it some other contractor who does this kind of work? It would be interesting if its is stress related but equally likely could be some moisture related defect. Whatever the source, they occur at regular patterns on the wall and are vertically oriented.

It appears to be a bulge that is leading on to a crack. The source of the problem is what I am worried about.

Hey Folks, New to the forum here. I saw this in my resale HDB unit on 3 of the walls here. There are bulges in the wall (Refer pic) at regular intervals. Does anyone know - 1. What are these defects? 2. How can they be fixed DIY? Cheers,
