Chipped melamine kitchen cabinets are a common frustration in NZ homes, but with the right preparation and products, you can restore them to a near-new finish without replacing the whole lot. The key is thorough surface prep — melamine is notoriously slippery, so skipping steps will lead to peeling paint down the track.
What You'll Need
Before you start, gather your materials. Most of these are available at Bunnings or Mitre 10:
- Melamine or two-part epoxy filler (such as a fine surface filler or automotive spot putty for small chips)
- Fine-grit sandpaper — 180 to 240 grit for flatting, 320 grit for finishing
- Degreaser or sugar soap
- Bonding primer specifically formulated for slick surfaces (melamine, laminate, or glass)
- Topcoat paint — water-based enamel or alkyd enamel in your chosen sheen
- Tack cloth, painter's tape, and a quality synthetic brush or small foam roller
- Safety glasses and a dust mask (P2 rated) for sanding
Step 1 — Clean the Surface Thoroughly
This step is non-negotiable. Kitchen cabinets accumulate grease, cooking oils, and cleaning product residue that will prevent paint from bonding. Wipe down every surface with a degreaser or sugar soap solution, then rinse with clean water and allow to dry completely. Even if the cabinets look clean, do this step.
Step 2 — Sand the Damaged Areas (and the Whole Surface)
Lightly sand the chipped areas with 180-grit sandpaper to remove any loose or flaking melamine and to feather the edges of the chip so there's no sharp lip. Then scuff-sand the entire cabinet surface with 240-grit paper — this is critical for adhesion on melamine. You're not trying to remove the melamine coating, just dull the sheen so the primer has something to grip. Wipe away all dust with a tack cloth.
Step 3 — Fill the Chips
For small chips and dents, a fine surface filler or two-part epoxy filler works well. Apply it with a flexible plastic spreader or putty knife, pressing it firmly into the chip and leaving it slightly proud of the surface. Follow the manufacturer's drying time — don't rush this. Once fully cured, sand the filled area flat with 240-grit, then finish with 320-grit for a smooth surface. Feather the edges carefully so the repair blends in. For very deep chips, you may need two thin coats of filler rather than one thick application.
Tip: Wipe the filled and sanded area with a damp cloth and let it dry before priming, to remove any remaining dust.
Step 4 — Apply a Bonding Primer
This is the most important product choice you'll make. A standard wall primer will not adhere reliably to melamine. You need a bonding primer designed for slick, non-porous surfaces. Resene and Dulux both offer suitable products — ask at your local trade store for their current recommendation for melamine or laminate surfaces, as product ranges do change.
Apply a thin, even coat and allow it to dry fully per the datasheet. Lightly sand with 320-grit between coats if applying a second primer coat, then wipe with a tack cloth.
Step 5 — Apply Your Topcoat
For kitchen cabinets, choose a water-based enamel or alkyd enamel in a satin or semi-gloss sheen — these are more durable and easier to wipe clean than flat finishes. Apply two thin coats rather than one thick coat, allowing full drying time between coats. A small foam roller gives a smoother finish than a brush on flat panels; use a brush for edges and detail areas.
Wattyl and Resene both produce kitchen-suitable enamel topcoats. Check the product's technical datasheet for recoat times and compatibility with your chosen primer.
Colour Matching
If you're only touching up a small area rather than repainting the whole cabinet, colour matching can be tricky. Take a door or drawer front to a Resene ColorShop or Dulux trade store — they can often colour-match using a spectrophotometer. Be aware that even a perfect colour match may look slightly different due to sheen variation or the age of the existing finish.
Realistic Expectations
Painted melamine will never be quite as hard-wearing as the original factory finish, but a properly primed and topcoated surface will hold up well in a normal kitchen environment. Avoid harsh abrasive cleaners and steel wool, which will scratch the new paint.
| Step | Key Product | Why It Matters |
|---|---|---|
| Clean | Sugar soap / degreaser | Removes grease for adhesion |
| Sand | 180–320 grit paper | Scuffs surface for grip |
| Fill | Fine surface or epoxy filler | Levels chips flush |
| Prime | Bonding primer (melamine-rated) | Critical adhesion layer |
| Topcoat | Water-based or alkyd enamel | Durability and washability |
When to Call a Professional
If your cabinets have widespread delamination, swelling from water damage, or structural issues with hinges and carcasses, a repaint alone won't fix the underlying problem. A qualified cabinet maker or painter can assess whether repair or replacement is the better option. For a full kitchen respray, professional cabinet painters use two-pack polyurethane systems that are far more durable than DIY brush-applied paints — the results are noticeably better. You can find qualified local cabinet makers and painters on tradedirectory.co.nz.
Safety note: Always work in a well-ventilated space when sanding and painting. Wear a P2 dust mask when sanding, and check product safety data sheets for any solvent-based products. See WorkSafe NZ for guidance on safe use of paints and solvents at home.
