What is Melamine?

Melamine is a type of finish made by fusing decorative paper, saturated with melamine resin, onto a particleboard or MDF substrate under high heat and pressure. The result is a hard, smooth, plastic-like surface that mimics the look of wood grain, solid color, or stone – but at a fraction of the cost of real veneer or paint.

In cabinetry, melamine is most commonly found on the interior surfaces of cabinet boxes – the shelves, the inside walls, and sometimes the back panel. It is durable against scratches, easy to wipe clean, and resists moisture better than raw particleboard. The trade-off is that it is not real wood, cannot be refinished, and chips at the edges if struck hard.

Key features of melamine

• Thermally fused: The paper and resin are bonded under heat, creating a permanent surface.
• Hard and smooth: Resists scratches, stains, and minor abrasion better than paint.
• Easy to clean: Wipes down with mild soap and water.
• Color and pattern variety: Available in solid colors, woodgrain prints, and stone looks.
• Cannot be refinished: Once damaged, the panel has to be replaced – sanding exposes the substrate.

BuyWholesaleCabinets uses cabinet-grade plywood with a clear UV-coated natural finish for the cabinet box interior instead of melamine. The visible interior surface is real wood (the outer ply of the plywood), which gives a warmer look, holds screws better, and stands up to long-term use without chipping at the edges.

FAQ

Is melamine the same as laminate?

They are similar but not identical. Both use a printed decorative layer over a substrate. Melamine is thermally fused directly to the substrate in one process. Laminate (like Formica) is a separate sheet that is glued onto the substrate after the fact. Laminate is typically thicker and more durable; melamine is thinner and lower cost.

Is melamine good for kitchen cabinets?

For interior shelves and box walls, it is functional and budget-friendly. For exterior surfaces like doors and visible side panels, it tends to look and feel like the budget material it is. Higher-quality cabinets use plywood or solid wood for visible surfaces and reserve melamine (if used at all) for hidden interiors.

Can melamine cabinets be painted?

Not easily. The melamine surface is non-porous and designed specifically to resist things like paint. With heavy sanding, a bonding primer, and a special paint, it can be done, but the result is rarely as durable as paint on wood. Most professionals recommend replacing melamine doors rather than painting them.

Does melamine swell when wet?

The melamine surface itself is moisture-resistant, but the particleboard or MDF substrate underneath is not. If water gets through a chipped edge or unsealed cut, the substrate will swell and the melamine surface will lift. This is why melamine is rarely used for sink base interiors.
