MDF vs MFC: What's the Difference and When Does It Matter?
Two common boards, two very different properties. Here's a clear breakdown of MDF and MFC — what each does well, and where each one belongs in a cabinetry project.
"MDF or MFC?" is probably the most common material question in a cabinetry workshop. They look similar on the shelf and both come in sheets. But they behave very differently, and mixing them up creates problems.
Here's the clear version.
MDF — Medium-Density Fibreboard
MDF is made from wood fibres broken down and bonded under heat and pressure with resin. The result is a dense, smooth, homogeneous board with no grain structure.
What it's good for:
- Painted door and drawer fronts — the smooth, grain-free surface takes primer and paint cleanly
- Routed profiles and decorative edges — it holds detail without chipping
- Internal shelving in wardrobes (lighter duty)
- Skirting and moulding applications
What it isn't good for:
- Carcasse construction in kitchens — it's heavy and doesn't hold screws at edges as well as chipboard
- Wet areas — standard MDF swells badly when it gets wet; even moisture-resistant MDF has limits
- Applications where weight is a concern
MFC — Melamine-Faced Chipboard
MFC is chipboard (compressed wood chips and resin) with a melamine resin surface bonded to both faces. The surface can be plain colour, woodgrain, stone-effect, or textured.
What it's good for:
- Kitchen and wardrobe carcasses — dimensionally stable, strong, screw-friendly
- Door fronts where a decorative finish is wanted (timber looks, solid colours)
- Shelving (choose 18mm for loaded shelves)
- Most standard cabinetry applications
What it isn't good for:
- Painted finishes — the smooth face doesn't grip primer the way MDF does, and any chipboard grain can show through paint over time
- Routed profiles on edges — the core chips
The simple rule
| You want... | Use... | |---|---| | A painted door front | MDF | | A timber or solid-colour door front | MFC (decorative) | | A kitchen carcasse | MFC (18mm) | | A routed edge or profile | MDF | | A wardrobe carcasse | MFC (16mm or 18mm) | | Wet area cabinetry | Moisture-resistant MFC |
What about cost?
MDF is generally slightly more expensive per sheet than equivalent MFC, and it's heavier — so factor handling and fitting labour into your quote if you're switching from MFC to MDF on a large job.
For most kitchen projects, the smart approach is MFC carcasses + MDF painted fronts (where painted is specified) or MFC throughout (where a decorative surface is specified). Don't use MDF for carcasse work unless there's a compelling reason.
