Ceilings cop a particular kind of scrutiny: daylight rakes across them from windows and shows every lump, patch and roller mark. They also collect the stains nothing else does - roof leaks, bathroom steam, smoke. Here's how ceiling painting actually works.
Why ceilings are painted flat
Flat (matt) ceiling paint reflects almost no light, which hides minor surface imperfections that any sheen would highlight. Standard ceiling white is also slightly different from wall white - formulated to resist yellowing and spatter less during rolling. This is one place where the specialist product genuinely earns its keep.
Water stains: block first, always
A dried water stain will bleed through ordinary ceiling paint no matter how many coats you apply. The fix sequence:
- Confirm the leak is fixed. Paint can't stop moisture that hasn't stopped.
- Let the plaster dry fully. Damp plaster plus paint equals bubbling.
- Stain-blocking primer over the mark. This seals the stain so it can't migrate into the topcoat.
- Then the ceiling paint.
Smoke and kitchen film
Smoke damage and years of kitchen grease film behave the same way - they bleed through. Cleaning first, then a blocking primer where needed, then topcoats.
When a ceiling needs repair, not paint
Sagging plasterboard, wide cracks that keep returning, and plaster that's drummy to the touch are repair jobs. Paint over them and you've bought a short delay. A straight answer about which situation you're in is part of any honest quote.
Colour beyond white
White isn't compulsory. Dropping a soft colour onto the ceiling can settle a tall room, and colour drenching - walls and ceiling in one tone - suits smaller rooms. But white flat remains the default for good reason: it bounces light and hides age.
