POP or gypsum false ceiling: the answer depends on your slab, not your budget

Gypsum board is factory-made to a consistent thickness, goes up on a GI framework and finishes flat. POP is mixed and applied wet on site over a chicken-mesh or board base, and the finish depends on the person applying it that day.

Gypsum is faster, cleaner and more predictable, and it cracks at the joints if the framework moves or the jointing tape was skipped. POP is more forgiving of curves and shapes, tolerates a slightly out-of-level slab better, and cracks in the field if the mix was wrong or it dried too fast.

For flat ceilings with clean lines — which is most contemporary work — gypsum wins on repeatability. For coves, curves, mouldings and anything sculpted, POP is still the sensible material, and pretending otherwise leads to a gypsum ceiling with a POP cove stuck on it, which is where cracks start.

Whichever you choose, the failure you actually want to avoid is moisture. Neither material forgives a leaking slab above. Fix the source before the ceiling goes up, because both will telegraph it within one monsoon.

Fix the leak before the ceiling. Both materials will telegraph it within one monsoon.
