Painting a kitchen ceiling that has grease buildup is not just a matter of rolling on a new coat. If the surface is dirty or oily, the new paint can fisheye, peel, or show stains through soon after the job is done.
In Auckland homes, especially in busy family kitchens, grease from cooking, steam, and airborne residue can build up over time. The good news is that with the right prep and paint system, you can get a clean, durable finish.
Why grease must be removed before painting
Grease acts like a barrier between the ceiling and the new paint. Even a paint labelled as durable won’t bond properly if it is sitting on top of oily residue. That is why the preparation stage matters more than the painting itself.
If you paint over grease, you may end up with patchy adhesion, discoloured spots, or paint that starts lifting around the cooktop area. A proper clean gives the sealer and topcoat a chance to grip the surface and last.
- Look for shiny patches, yellowing, or sticky areas near the cooking zone.
- Check corners and around extractor fans, where residue often collects.
- If the ceiling has mould as well as grease, treat both problems before painting.
How to clean the ceiling before painting
Start by protecting benchtops, appliances, and flooring with drop sheets. Turn off power to light fittings if you need to work around them, and use a stable ladder or work platform so you can reach the whole ceiling safely.
Wash the ceiling with a suitable degreasing cleaner mixed according to the label. For many homes, warm water and a sugar soap solution works well, but stubborn kitchen grease may need a stronger degreaser. Wipe the ceiling with a clean sponge or cloth, then rinse with clean water to remove any cleaning residue.
Do not scrub so hard that you damage the existing paint. The aim is to remove the grease, not scour the plasterboard. Once cleaned, allow the ceiling to dry fully before applying any sealer or paint.
- Use two buckets: one for cleaning solution, one for rinsing.
- Change cloths often so you are not spreading grease around.
- Feather-sand any rough edges once the ceiling is dry.
- Spot-prime stained or nicotine-marked areas if needed.
Prime, then paint with the right product
After cleaning, apply a stain-blocking or problem-surface sealer where needed, especially if the grease has caused yellowing or discolouration. This helps prevent stains bleeding through the topcoat and gives you a more even finish.
For most kitchen ceilings, a good-quality interior ceiling paint with a washable, low-sheen finish is a practical choice. It helps reflect light without showing every mark, and it is easier to keep clean in a working kitchen. Apply at least two thin coats rather than one heavy coat, and keep a wet edge to avoid lap marks.
If you are working in a kitchen with poor extraction, consider improving ventilation as part of the overall solution. A good extractor fan or rangehood will reduce future build-up and help the paint job last longer.

Frequently Asked Questions
Can I paint over a greasy kitchen ceiling without cleaning it?
No. Paint will not bond properly to grease, and the finish is likely to fail. Always clean the ceiling thoroughly first and let it dry before priming and painting.
What cleaner should I use on a kitchen ceiling before painting?
A sugar soap solution or a proper degreasing cleaner is usually suitable, provided you follow the label directions. For stubborn buildup, a stronger kitchen degreaser may be needed.
Do I need to prime a kitchen ceiling after cleaning?
If there are grease stains, yellowing, or previous paint issues, a stain-blocking primer or sealer is a smart step before topcoating.
