Repainting kitchen cupboards is one of the most cost-effective ways to refresh your kitchen — but it's also one of the most common DIY paint jobs to go wrong. Chipping, peeling, and scratching usually come down to three things: inadequate surface preparation, the wrong primer, or using a paint that isn't tough enough for a high-traffic kitchen environment. Follow these steps and you'll end up with a finish that looks great and stands up to daily use.
Why Kitchen Cupboards Chip So Easily
Kitchen surfaces cop a lot of punishment — steam, grease, moisture, and constant handling. Standard wall paint simply isn't formulated to handle this. It stays slightly flexible and soft, which means it chips and scratches when knocked. The key is using a hard, enamel-type or cabinet-specific paint combined with thorough preparation. Skipping either of these steps is the number-one reason DIY cupboard repaints fail.
Choosing the Right Paint
For kitchen cupboards, you want a paint that cures to a hard, washable film. Look for:
- Waterborne alkyd or enamel paints – These are the gold standard for cabinetry. They brush and roll smoothly, have lower odour than traditional oil-based paints, and cure rock-hard. Resene Lustacryl and Dulux Aquanamel are popular NZ options specifically suited to trim and cabinetry.
- Cabinet-specific paints – Some ranges are formulated exclusively for furniture and cabinetry and offer excellent hardness and adhesion.
- Sheen level – Choose a semi-gloss or gloss finish. These are easier to wipe clean and more durable than satin or low-sheen options.
Avoid standard interior wall paints — even premium ones — on cupboard doors. They're not designed for the wear cabinetry receives.
Gather Your Materials
Before you start, get everything together:
| Item | Purpose |
|---|---|
| Sugar soap or degreaser | Remove grease and grime |
| 120–180 grit sandpaper | Scuff existing surface for adhesion |
| 240 grit sandpaper | Light sand between coats |
| Quality primer/undercoat | Adhesion and stain blocking |
| Cabinet enamel or waterborne alkyd paint | Durable topcoat |
| Quality synthetic brush and small foam roller | Smooth application |
| Tack cloth | Remove dust before painting |
| Screwdriver | Remove doors and hardware |
Step-by-Step: How to Repaint Cupboards
1. Remove Doors and Hardware
Take doors off their hinges and remove all handles, knobs, and hinges. Painting flat on a workbench gives a far better finish than painting in place, and you'll avoid getting paint on your hardware.
2. Clean Thoroughly
This is the most important step most DIYers rush. Kitchen cupboards accumulate grease and cooking residue that will prevent paint from bonding properly. Wash all surfaces with sugar soap or a dedicated degreaser, rinse well, and allow to dry completely. Don't skip this — no amount of good paint will stick to a greasy surface.
3. Sand the Existing Surface
Using 120–180 grit sandpaper, scuff the entire surface — doors, frames, and drawer fronts. You're not trying to strip the paint back to bare timber; you just want to dull the sheen and give the new primer something to grip. Sand with the grain on timber. Wipe down with a tack cloth to remove all dust.
If the existing paint is flaking or in poor condition, you may need to strip it back further or fill any chips with a fine surface filler before sanding smooth.
4. Apply a Quality Primer
Don't skip the primer — it's what locks everything together. Use a primer specifically suited to the substrate (MDF, timber, or previously painted surface). For MDF doors, use a high-build MDF primer as MDF is very absorbent, especially on edges. Apply one to two coats, allowing full drying time between coats, then lightly sand with 240 grit and tack off.
5. Apply Your Topcoats
Apply your chosen enamel or cabinet paint in thin, even coats — two to three coats is typical. Thin coats dry harder and are less prone to runs and sagging. Use a quality synthetic brush for edges and a small foam roller for flat panels to minimise brush marks. Lightly sand with 240 grit between coats once fully dry, and tack off before the next coat.
6. Allow Full Cure Time
This is where patience pays off. Waterborne enamels may feel dry to the touch within hours, but they take days to weeks to fully cure to their maximum hardness. Rehang doors carefully and avoid heavy use for at least a week. Don't stack items against freshly painted surfaces during this period.
Common Mistakes to Avoid
- Painting over grease – Paint will peel within weeks.
- Skipping primer on MDF – The edges will soak up paint and never look right.
- Applying thick coats – Causes runs, slow drying, and a softer finish.
- Rehanging too soon – Doors can stick and the paint can tear when opened.
- Using wall paint – It won't cure hard enough for cabinetry.
When to Call a Professional
If your cupboards have significant damage, are made from a tricky substrate like veneer or melamine, or you want a truly flawless spray finish, it's worth calling in a professional painter. Spray application gives a factory-smooth result that's very difficult to replicate with a brush and roller. A qualified painter will also know exactly which products suit your specific cupboard material. You can find experienced local painters on tradedirectory.co.nz.
