Causes of Cracked Plaster Ceilings
1) Building Structure Movement
Buildings naturally “settle” over time. Plasterboard joints can crack when the structure shifts slightly.
2) Moisture & Water Leaks
Among the most common causes in KL:
Leaking pipes (from the unit above / bathroom)
Leaking roof/awning
Leaking air conditioner
Prolonged moisture weakens plasterboards and causes recurring cracks.
3) Weak Ceiling Framing
Cheap framing, excessive spacing between frame members, or rushed installation can make the ceiling crack easily.
4) Fan & Light Vibrations
Installing a ceiling fan without proper support places extra load on the plaster ceiling structure.

How to Repair a Cracked Plaster Ceiling (DIY & Professional)
A) DIY for Small Cracks (Fast & Cost-Saving)

Steps:
Clean the cracked area (remove peeling paint)
Apply filler and smooth it out
Let it dry (follow the product instructions)
Sand until smooth
Repaint the ceiling for an even finish
Tip: If the crack reappears within a short time, it means the real cause has not been resolved yet (for example: a leak or weak framing).
B) Professional Repair for Serious Cracks (Safer)
For large or recurring cracks, the process usually involves:
Opening up the damaged section
Replacing the plasterboard
Inspecting and reinforcing the frame
Anti-moisture treatment
Repainting and final finishing
