Can I paint melamine or laminate furniture?

Melamine and laminate faces are thermosetting plastic films pressed onto chipboard or MDF. They are hard, completely non-porous and chemically inert, which is exactly why they wipe clean and exactly why ordinary paint slides off. Nothing in a standard primer bonds to them. The job is entirely about creating a mechanical key and using a primer designed to grip a plastic.

What you'll need

• A degreaser or sugar soap, and clean cloths
• Abrasive paper around 180–240 grit, or an abrasive pad
• An adhesion, melamine or multi-surface primer
• A hard-wearing water-based satinwood or acrylic eggshell
• A small foam or microfibre roller, for a smooth finish

Step by step

1. Degrease far more thoroughly than feels necessary.Melamine holds grease, polish and silicone from cleaning sprays on a surface with no absorbency at all, so all of it sits on top waiting to break the bond. Wash with sugar soap or a proper degreaser, rinse with clean water, and dry. Do it twice on anything from a kitchen.
2. Abrade the whole surface until the shine is gone.You are not removing the melamine — it is only a fraction of a millimetre thick and cutting through it exposes the board. You want the gloss knocked off uniformly so there is a mechanical key. Work it over evenly, then vacuum and wipe the dust off with a damp cloth.
3. Seal any exposed chipboard or MDF edges.Where the melamine has chipped, or on a cut edge, the board underneath is exposed and will drink paint and swell. Fill any damage, sand flat, and seal those areas with a suitable sealer before priming.
4. Use a genuine adhesion primer.This is the step that does the work: a specialist melamine, multi-surface or adhesion primer formulated to bond to non-porous plastics. General-purpose wood or wall primers will not. Apply it thin and even, and respect its overcoating window — many of these primers want the topcoat on within a stated period.
5. Topcoat with a hard trim paint, thin and twice.A water-based satinwood, acrylic eggshell or furniture paint. Two thin coats over one thick one, every time, because thickness is what stays soft and blocks. A small foam or microfibre roller gives the most uniform surface on a flat door.
6. Let it cure before you use it hard.Touch-dry is not cured. A trim paint on a cupboard door reaches full hardness over days to weeks, and putting the doors back into daily use immediately is how the edges get damaged. Rehang them, but treat them gently at first.
7. Be realistic about where it will last.Vertical surfaces that get touched but not abraded — cupboard doors, wardrobe fronts, sides — do well. Shelf tops that things slide across, drawer runners, and edges that get knocked will wear through eventually, whatever you use.

Tips

• Test your system on the back of a door or the inside of a carcass first. Twenty-four hours later, try to pick the paint off with a fingernail and try a piece of tape on it. If it lifts, the preparation was not enough.
• A spray-applied finish is dramatically better on flat melamine doors than any brush job, if you have somewhere to do it and can mask properly.
• Removing doors and handles and working flat is worth the extra half hour: horizontal surfaces let the paint flow out and eliminate runs on the edges.

Common mistakes

• Sanding through the melamine face — The film is very thin and the chipboard beneath is porous and swells. You only need the shine gone, not the surface removed.
• Using a standard wood or all-purpose primer — Nothing in it bonds to a cured non-porous plastic. It will look fine for weeks and then peel off in sheets from the first knock.
• Painting kitchen cupboards without degreasing — Cooking grease is invisible, everywhere and completely fatal to adhesion. It is the reason most failed kitchen cupboard repaints fail.
