Painting Panelled Doors in London Period Homes

A well-painted panelled door is one of the most visible signs of quality decoration in a period interior. It is also, in the hands of an inexperienced decorator, one of the easiest things to get wrong. Runs in the panels, brush marks across the stiles, missed spots in the moulding quirks, and a finish that starts lifting within two years -- all of these are common, and all of them are avoidable. This is how we approach panelled doors in London's Victorian, Edwardian and Georgian properties.

Understanding the Anatomy of a Panelled Door

Before you can paint a panelled door correctly, it helps to understand what the different parts are called, because the correct painting sequence follows the structure of the door.

A standard four-panel Victorian door consists of:

Panels -- the recessed fields within the frame, typically four in number on a standard door
Mouldings -- the shaped edges between the panel field and the surrounding framing, which catch light and cast shadow
Muntins -- the central vertical member dividing the panels
Rails -- the horizontal members (top rail, middle rails, bottom rail)
Stiles -- the outer vertical members on either side of the door

The correct painting sequence -- panels first, then mouldings, then muntins, then rails, then stiles -- is not arbitrary. It is designed to ensure that wet edges always meet wet edges, preventing lap marks where a painted section has partially dried before an adjacent section is applied.

Preparation: The Work That Determines the Outcome

The quality of a painted panelled door is determined almost entirely by preparation. On an existing door in a London period home, the following preparation steps apply:

Clean the door thoroughly. Doors accumulate grease, fingerprints and general grime around handles and at the stile edges where hands regularly contact the surface. A sugar soap solution applied with a cloth and rinsed off is the correct starting point for any door that is being repainted rather than stripped.

Assess the existing paint. Run a hand over the existing painted surface. If there are significant ridges from previous brush marks, drips, or areas of failing paint, these need to be addressed before any new coat goes on. Light sanding with 180-grit sandpaper will key the surface and reduce minor ridges. Heavier flaking or poorly-adhering paint should be stripped back to a sound substrate -- either by careful heat gun or chemical stripper, depending on the profile complexity.

Strip the mouldings. The mouldings are where paint tends to accumulate most aggressively over years of redecoration. A small shave hook, used carefully along the quirk (the narrow groove at the junction between the moulding and the panel), will remove paint build-up that no amount of sanding will address. Take care not to cut into the timber itself.

Fill holes, cracks and imperfections. Fine two-part filler is the right material for timber doors -- it is harder than standard decorator's filler and will not shrink after application. For hairline cracks along grain lines, flexible acrylic filler is better. Sand all filled areas flush after curing.

Prime any bare timber. If preparation has exposed bare wood at any point -- stripped mouldings, filled areas, or a door that has been completely stripped -- a proper timber primer must be applied before undercoat. Using an undercoat or topcoat directly over bare wood will result in uneven absorption and a patchy finish.

The Correct Painting Sequence

With the door prepared and primed where necessary, painting proceeds as follows:

1. Panels. Begin with the recessed panel fields. Apply paint to the centre of each panel and work outward toward the moulded edges with a 50mm brush, leaving a wet edge at the moulding line. Do not attempt to paint into the moulding at this stage.

2. Mouldings. Using a 25mm brush, work the paint into the moulding profile immediately, while the panel wet edge is still workable. The key here is to load the brush adequately but not excessively -- too much paint in a moulding will pool in the quirk and form a run. Work in the direction of the grain, following the moulding profile around the panel. Use the tip of the brush to lay off and remove excess.

3. Muntins. The central vertical member between the panels is painted next, working from top to bottom. Keep a wet edge at the rail junctions.

4. Cross rails. Paint the horizontal rails across the width of the door. At the junctions with muntins and stiles, lap slightly into the adjacent wet surface to avoid a hard line.

5. Stiles. Finish with the outer vertical members, working from top to bottom in long, light strokes. Lay off in the direction of the grain.

6. The door edge. The latch edge and hinge edge should be painted to match the face in the same operation. The convention in period properties is that the hinge edge of the door matches the room it opens into, and the latch edge matches the room the door swings toward -- but in practice, painting both edges to match the face is more common and entirely acceptable.

Brush Choice and Technique

The quality of the finish on a panelled door depends heavily on brush quality. Use a natural bristle brush for oil-based paints and a good synthetic brush for waterborne finishes. A 50mm brush for the main panel fields, a 25mm cutting-in brush for the mouldings, and a 63mm or 75mm brush for the stiles are the standard set.

Lay off lightly at the end of each section -- that is, draw the brush across the surface with minimal pressure and almost parallel to the surface, in the direction of the grain, to remove brush marks and leave a smooth film. This is the technique that distinguishes a professional finish from an amateur one.

Colour Choices for Period Doors

Woodwork white. The most common choice in London period homes, and entirely appropriate. Off-whites rather than brilliant white tend to look better in older properties -- Farrow and Ball's All White or Wimborne White, Little Greene's Loft White, or a comparable mid-sheen white in a quality eggshell or oil-based paint.

Dark doors. Dark-painted interior doors have become increasingly popular in London period homes, and they work extremely well in hallways and on prominent doors where a strong first impression is wanted. Farrow and Ball's Railings, Pitch Black or Down Pipe, Little Greene's Obsidian or Lick's deep navy ranges are all used frequently. Dark doors in oil-based eggshell have a depth and richness that water-based finishes struggle to replicate.

Colour-matched to walls. Painting a door in the same colour as the surrounding wall, or close to it, is a contemporary approach that can look very effective in certain rooms -- particularly where the door is set into an alcove or where the architecture is quite plain. It requires a careful choice of sheen level: a door in dead flat emulsion will not survive heavy use. An eggshell or satin in the wall colour is the practical approach.

Durability and Maintenance

A properly prepared and properly painted panelled door in a quality eggshell should last seven to ten years in normal use before it requires more than a light clean or a small touch-up at handle areas. The keys to longevity are: complete preparation, a proper primer where needed, adequate dry time between coats, and a finish product designed for woodwork rather than walls.
