Picking the right paint sheen for a ceiling is one of those decisions that seems minor but can make or break the finished look of a room. Get it wrong and you'll highlight every imperfection in the plasterboard — get it right and the ceiling simply disappears into the background, letting your walls and furnishings do the talking. Here's what you need to know before you crack open a tin.
Understanding Paint Sheen Levels
Paint sheen refers to how much light a dried paint film reflects. From least to most reflective, the common options are:
| Sheen Level | Also Called | Light Reflection | Typical Use |
|---|---|---|---|
| Flat / Matt | Dead flat | Very low | Ceilings, low-traffic walls |
| Low Sheen | Velvet, eggshell | Low | Interior walls |
| Semi-Gloss | — | Medium-high | Trims, doors, wet areas |
| Gloss | High gloss | High | Trims, furniture |
For most ceilings, flat or matt is the go-to choice among professional painters across New Zealand.
Why Flat Paint Is the Standard for Ceilings
Ceilings are lit from below — light rakes across the surface and picks up every bump, join, and imperfection. A flat finish scatters light rather than reflecting it, which visually softens those surface irregularities. This is especially important with standard GIB plasterboard ceilings, where stopping (plastering) joins and screw holes are common.
A gloss or semi-gloss ceiling, by contrast, acts almost like a mirror under certain lighting conditions. You'll see every ridge, roller mark, and patch — not a great look.
Key benefits of flat ceiling paint:
- Hides surface imperfections
- Gives a clean, receding look that makes rooms feel taller
- Easy to touch up (low sheen blends well)
- Widely available and generally more affordable
What About Kitchens and Bathrooms?
This is where things get a little more nuanced. Flat paint is not very washable and can absorb moisture, which is a problem in high-humidity rooms. New Zealand's BRANZ research highlights that moisture management is critical in wet areas — mould on ceilings is a common issue in poorly ventilated Kiwi homes.
For kitchen and bathroom ceilings, consider a low-sheen or eggshell finish rather than dead flat. These offer:
- Better moisture resistance
- Improved washability (you can wipe off cooking splatter or condensation marks)
- Still low enough reflectivity to hide most imperfections
If your bathroom has poor ventilation, fixing the airflow is more important than paint choice — but using a mould-resistant ceiling paint is a smart extra step. Both Resene and Dulux offer ceiling paints with mould inhibitors specifically suited to NZ conditions.
Choosing the Right Product
Most major NZ paint brands offer a dedicated ceiling white formulated for flat application. These are slightly thicker than wall paints, which reduces drips and spatter when rolling overhead.
- Resene Ceiling Paint – a popular flat white with good hide and spatter resistance
- Dulux Ceiling White – widely available at Mitre 10 and Bunnings
- Wattyl also offers ceiling-specific products through trade and retail outlets
Always check the product's VOC (volatile organic compound) content if you're sensitive to paint fumes — low-VOC options are available from all major brands.
Colour and Sheen: A Quick Note
Most ceilings are painted white or off-white, which reflects light downward and brightens the room. If you're going for a coloured ceiling (a bold design choice that's becoming more popular), the same sheen rules apply — stick to flat or low-sheen in the chosen colour. Bear in mind that darker colours on a flat finish can be harder to touch up evenly.
Preparation Makes All the Difference
No matter which sheen you choose, proper prep is essential:
- Fill and sand all cracks, screw holes, and joins flush
- Prime any bare plaster or repaired areas — skipping this causes flashing (patchy sheen variation)
- Clean the surface to remove dust, grease, or old flaking paint
- Apply two coats for even coverage, allowing full drying time between coats
Poor prep is the number one reason a ceiling looks patchy or shows imperfections after painting — even with the best flat paint.
When to Call a Professional
Painting a ceiling is physically demanding and fiddly. If your ceiling has:
- Extensive cracking or water damage — this may indicate a structural or plumbing issue that needs investigating first
- Textured or specialist surfaces — popcorn or acoustic ceilings require specific products and techniques
- High stud heights — working safely at height requires proper scaffolding; WorkSafe NZ has clear guidelines on working at height safely
- Mould that keeps returning — this may point to a ventilation or moisture problem beyond a paint fix
A qualified painter will also achieve a much smoother, more consistent finish than most DIYers, particularly on large open-plan ceilings. You can find experienced local painters on tradedirectory.co.nz.
