Paint quality, finish, and colour make an enormous difference to the character of a period London home. Here is a practical guide to specification, from primer to final coat.
Decoration is the finish that defines a completed renovation. Everything underneath can be perfect — plumbing, structure, insulation, joinery — and a poor paint job will undermine it all. Conversely, in a period London property with well-maintained original features, a beautifully executed decoration programme can transform the quality of the space at modest cost relative to structural work.
This guide covers the key decisions in a paint specification for a period London property.
Paint quality: the case for using the right product
The gap between budget and premium paint is not primarily about colour — it is about pigment concentration, binder quality, and coverage. A premium paint (Farrow & Ball, Little Greene, Papers & Paints, or similar) has higher pigment loading, meaning it covers better, shows more accurately in different lights, and has better durability. The cost difference per litre is significant; the cost difference per room is modest when you account for the labour cost of applying it.
For the walls and ceilings of a period London property, there is another dimension: traditional surfaces. Lime plaster, the original substrate in most Victorian and Georgian London buildings, is vapour-permeable — it allows moisture to move through it. Conventional modern emulsions and eggshells can reduce vapour permeability, trapping moisture in the wall. For original lime plaster walls in good condition, a traditional distemper (Earthborn, Brouns, or Papers & Paints) or a modern microporous emulsion is more appropriate than a vinyl matt.
Understanding finish types
Flat/dead flat: Completely matt, no sheen. Shows surface imperfections less than any other finish. The correct choice for walls in period properties — particularly corniced reception rooms where a flat finish reads as assured and settled. Farrow & Ball's Estate Emulsion, Little Greene's Intelligent Matt.
Matt emulsion: A slight sheen, standard for most residential walls. More washable than flat/dead flat. Appropriate for kitchens, hallways, and children's rooms where washability matters.
Eggshell: A semi-gloss finish for joinery (skirtings, architraves, doors, window frames). Oil-based eggshell gives a harder, more durable finish than water-based but takes longer to dry and has higher VOC content. For period properties where the joinery is being painted in a traditional manner, oil-based eggshell gives a depth and durability that water-based products are still catching up with.
Gloss: High sheen, typically used for external joinery (window frames, front doors) and some period internal joinery where high-gloss was the original finish. Difficult to apply without showing brush marks — requires meticulous preparation and often multiple coats.
Lime wash: A traditional finish for the exterior render of Georgian and pre-Georgian buildings. Vapour-permeable, slightly textural, and the correct material for lime-rendered facades. Not appropriate for modern masonry paints or cement render.
Colour selection for period properties
Period properties have a distinctive quality of light — particularly in London's north-light drawing rooms and the deeply shadowed interiors of terraced houses. Colours that look clean and bright in a showroom or on a colour card can read unexpectedly dark or cool in these conditions.
Test colours on large samples (at least A4 size) applied to the actual wall and assessed at different times of day and in artificial light before committing. Paint companies provide tester pots for this reason — the cost of testing is negligible against the cost of repainting.
Period-appropriate palettes: - Georgian rooms: off-whites, stone colours, and pale neutrals (Farrow & Ball's Elephant's Breath, String, Pointing, Old White). Deep strong colours on woodwork in Regency-period rooms (dark greens, reds, lead greys). - Early Victorian: stronger colours — drabs, ochres, and deep greens became fashionable. Joinery often picked out in a deeper tone of the wall colour. - Late Victorian and Edwardian: the Arts and Crafts palette — sage greens, dusty blues, warm ochres, terracotta. Deep olive greens and burgundies in hallways.
Preparation: the unseen work
A paint job is only as good as the preparation beneath it. In a renovated period property:
New plaster: Must be fully dry before painting. Apply a mist coat (emulsion diluted 10% with water) as a primer — this seals the new plaster without blocking out the suction entirely. Two full coats of final emulsion after the mist coat is standard.
Existing plaster in good condition: Wash down to remove dust, grease, and any friable material. Fill hairline cracks with fine surface filler. Sand smooth when dry. Apply a primer/undercoat if the surface is very porous.
Joinery: All joinery (doors, skirtings, architraves) should be filled, knotted (for new softwood — apply knotting solution to resin pockets before priming), primed, and undercoated before the final finish coat. For an oil-based eggshell system: one coat oil primer, one undercoat, two finish coats. Denib (light sanding) between coats for a smooth result.
Previously painted surfaces: Wash down with sugar soap. Sand to key the surface. Fill any holes or cracks. If there is a significant colour change (particularly going from dark to light), an appropriate blocking primer will reduce the number of coats required.
Programme and drying times
Paint works have their own logic: you cannot rush drying times without compromising the result. Allow minimum:
- —4 hours between water-based coats
- —16–24 hours between oil-based coats
- —48 hours before re-coating on high-build or specialist products
In a London renovation in winter (October–March), low temperatures slow drying times significantly. A heated and ventilated building accelerates drying but must not create excessive draughts that contaminate wet surfaces.
Decoration is typically the last trade to work throughout the building, following joinery installation and before final floor finishes are laid. It should not be rushed to meet a handover date — rushed decoration is immediately visible to anyone familiar with quality.
ASAAN employs directly a skilled decorating team for all finished decoration on our renovation programmes, rather than subcontracting this trade. The quality of the final coat is a direct reflection of the care taken in everything that preceded it.
