Decorating a Fully Panelled Room in London: Georgian, Victorian and MDF Reproduction Panelling

Panelled Rooms: The Most Demanding Decorating Work

A fully panelled room — walls lined from skirting to dado or from floor to ceiling in timber or MDF panelling — is among the most demanding painting projects in London residential decoration. The complexity of profiles, the number of internal and external angles, the difficulty of achieving consistent coverage on recessed fields without clogging the moulding arrises, and the unforgiving nature of eggshell or gloss in raking light all demand a level of preparation and technique that separates competent decorators from exceptional ones.

Done well, a painted panelled room is one of the finest finishes a London property can have. Done poorly, it looks worse than bare plaster.

Georgian Box Panelling

Georgian box panelling — typical of Belgravia, Mayfair, and Marylebone townhouses built between roughly 1720 and 1840 — uses flat-fielded panels within a simple bolection or ovolo moulding. The panels themselves are relatively flat, the moulding profiles are restrained, and the overall geometry tends toward the rectilinear.

The preparation challenge on genuine Georgian joinery is the accumulated paint layers. In properties that have not been stripped in living memory, there may be twelve to twenty layers of paint on the panelling — particularly in hallways, stairwells, and formal reception rooms that were repainted regularly. At this stage the original moulding detail is beginning to be obscured: the crisp arrises have become rounded, the junction between stile and moulding is a series of drips and sags rather than a clean shadow line.

The decision whether to strip and repaint or to prepare over existing paint is case-specific. Where moulding detail is being significantly obscured, full stripping — using a hot air gun and moulding scrapers, or chemical strippers on complex profiles — followed by careful rubbing down and priming is the correct approach. Where the existing paint is sound and detail is preserved, thorough preparation (degreasing, rubbing down, and filling any cracks at the panel field/moulding junction) can give an excellent result without the cost and disruption of stripping.

The panel crack problem: Timber panels expand and contract seasonally. In a dry London winter with central heating running, the field panels will shrink across the grain, opening hairline cracks at the joints between field and moulding. These cracks cannot be permanently filled with a rigid filler; they must either be filled with a flexible decorator's caulk (which will accept paint but will not sand smooth) or accepted as a characteristic of the original timber construction.

Victorian Raised and Fielded Panelling

Victorian panelling — found in townhouses and terraces of the 1850–1910 period across Chelsea, Kensington, Islington, and Hackney — typically uses raised and fielded panels: the field projects slightly from the surrounding rail and stile, surrounded by a planted moulding. The profiles are often more complex than Georgian panelling: ovolo, bolection, and egg-and-dart mouldings appear frequently, particularly in the more ambitious properties of the middle Victorian period.

The raised-and-fielded format creates more profile complexity and more surfaces at different angles, all of which must be covered without runs, sags, or bare patches. The raised field — which receives light across its face — and the recessed shadow around the moulding junction are the areas where preparation failures and application errors are most visible.

Painting sequence for raised and fielded panels: The correct order of work, which ensures wet paint does not drip onto freshly painted areas, is: mouldings first (in and around the moulding profiles), then the panel fields, then the stiles and rails. The mouldings should be painted with a small sash brush that fits the profile; trying to cut in with a standard brush produces uneven coverage in the depths of the profile and excessive paint build-up on the arrises.

MDF Reproduction Panelling

Many London properties built in the 1990s and 2000s — and many older properties that have been refurbished — have MDF reproduction panelling: flat MDF sheets routed or moulded to replicate the appearance of period panelling, painted and installed on a flat wall.

The preparation requirements for MDF are different from those for timber. MDF has no grain, does not expand or contract significantly across its face, and has no existing paint build-up if new. However, it is highly absorbent at cut edges (the routing and moulding cuts expose raw MDF fibre that will absorb paint indefinitely without sealing) and requires specific primer treatment.

Priming MDF panelling: All routed edges and profiles must be sealed with a high-build MDF primer (Zinsser Bulls Eye 1-2-3 is widely used in the trade, as is Dulux Trade MDF Primer) applied in two coats and sanded back between coats. Without this sealing, the paint coats applied over the profiles will appear dull and porous compared to the flat face areas of the panel, and the finish will never look consistent.

Junction with the wall: Where MDF panelling meets a painted plaster wall above the dado rail, the junction must be caulked and allowed to cure before painting. This joint will move with seasonal changes in temperature and humidity; a paintable flexible caulk (Decorator's Mate, UniBond) is the correct material.

Colour and Sheen Selection

Colour: Historically, painted panelling in London period properties was painted in a single colour from skirting to cornice — in many cases this was off-white or stone, with the colour differentiation coming from gilded moulding details or a contrasting wallpaper above the dado. Contemporary practice often uses the panelling colour as the dominant element of the room.

Deep, saturated colours work particularly well on panelling — Railings, Hague Blue, Studio Green, Porphyry Pink, and their equivalents from Little Greene and Mylands — because the multiple surface angles and moulding profiles catch light differently, creating tonal variation within a single colour that makes the room interior feel three-dimensional and architectural. A pale colour on panelling has less of this quality; it can look flat or empty.

Painting all surfaces — panelling, walls above, cornice, and ceiling — in the same colour is increasingly common and is known as "colour drenching" or "tone-on-tone." In a panelled room with complex detail, this approach can be extraordinarily effective: the detail reads in relief and shadow without the distraction of colour contrast.

Sheen level: Eggshell is the standard professional choice on panelling in London interiors. It is durable, washable, and provides enough sheen to define the profiles without the hard, reflective quality of gloss. Full gloss on panelling is traditional (it was the standard before water-based eggshell products became reliable) and still looks exceptional when applied by a skilled hand — but it requires more thorough preparation and is less forgiving of substrate imperfections.

Dead flat on panelling is unusual and generally inappropriate — the purpose of painting panelling, at least in part, is to define the geometry with light and shadow, which requires some sheen.

Order of Work

The correct sequence for a full panelled room decoration:

1. Preparation: fill, sand, caulk joints, prime bare areas
2. Ceiling: cut in and roll; two coats
3. Cornice: cut in against ceiling and walls
4. Panelling: mouldings first, fields second, stiles and rails third
5. Skirting and architraves
6. Final cut-in touches where surfaces meet

Each coat must be fully dry and lightly sanded before the next is applied. For a quality eggshell finish on complex panelling, three coats (primer, undercoat, finish) is the minimum; four coats delivers a noticeably better result.
