Painted, wood veneer or solid wood doors: how to choose

Five piece painted doors

A five piece door is a frame of four rails and stiles around a centre panel. Painted, that centre panel should be MDF. Solid wood panels and solid wood frames expand and contract with humidity, and a painted film cannot stretch with them, so a hairline opens at the joints through the first heating season. MDF does not move the same way, so the paint holds.

Expect a hairline at the joints on any painted door built from solid wood. It is a property of the material, not a defect, and it is the main reason Valmont specifies MDF centre panels for painted work.

Slab doors

A slab door is one flat face with no frame and no panel. It reads quiet, it is the easiest surface to clean, and it takes an integrated pull well, since the pull can be machined straight into the edge or the face. Slabs can be painted, veneered or laminated. Painted slabs show the flattest colour of any door, so the substrate and the spray work have to be right.

Wood veneer and sequence matching

Veneer is a thin layer of real wood over a stable core. Because the core does not move much, a veneered door stays flatter than a solid one, and because the leaves come off the same log, they can be laid in order so the grain continues across doors, drawers and panels. That is sequence matching, and it is what makes a wall of cabinetry read as one surface.

• Rift sawn oak gives straight, even grain lines with almost no cathedral figure, which suits tall runs and long horizontal drawer banks.
• Plain sawn oak gives the wider cathedral figure, warmer and busier, better on shorter runs and single doors.
• Walnut darkens and warms with light exposure over the first year or two, so a panel kept behind a door will not match one in the sun.
• A clear matte coat lets the grain read without gloss and keeps the colour closer to the raw wood than a warm oil finish does.
• Sequence matching has to be planned before cutting, and it usually means ordering more material than the net area.

Solid wood and fluted fronts

Solid wood has depth you can feel at the edge, and it can be sanded and refinished rather than replaced. It also moves with the seasons, so joints open and close a little through the year. Fluted fronts are machined grooves that catch light and throw shadow, usually in solid stock or a solid faced panel. Fluting reads best on islands, feature walls and bar fronts where light crosses it.

How each ages, and touch-ups

Paint takes the visible wear first: a chip at a corner, a mark where a ring hits the door. It is also the easiest to correct, since a matched touch-up or a single door respray brings it back. Veneer wears very slowly on the face and shows its age at the edges. Solid wood hides knocks in the grain and takes a sand and refinish where paint cannot.

Keep a labelled offcut and the finish code from the job. A door can be remade years later, but matching a finish without a record means matching by eye against a surface that has already aged.

Care

All three want the same routine: a soft damp cloth, a dry pass after, and no abrasive pads or solvent cleaners. Wipe spills off quickly at the sink and the dishwasher, since standing water at a bottom edge is what damages any door. Keep steam away from door faces by pulling the dishwasher door open only after the cycle has cooled, and keep indoor humidity steady through the winter.

Which rooms suit which

Kitchens take painted doors well, since touch-ups are simple and colour ties the room to the walls. Media walls, offices and libraries suit veneer, where a sequence matched run across a long wall is the point. Vanities and laundry rooms want painted or veneered slabs for cleaning. Islands, bar fronts and feature walls are where fluted and solid wood earn their place.
