Painting and Finishing Parquet Floors in London Period Homes

The Parquet Floor: An Asset Worth Protecting

Original parquet flooring is one of the most desirable features a London period home can possess. Laid in herringbone, basket-weave, or brick patterns from thin strips of hardwood — typically oak, pine, or teak — original parquet in good condition adds significant character and value to a property. The question of how to finish it — whether to paint, oil, wax, or seal — requires careful consideration of the floor's condition, the room's use, and the aesthetic you are trying to achieve.

Paint vs Seal: Understanding the Choice

Painting a parquet floor is a permanent decision in practical terms. Once paint is applied, removing it without damaging the individual blocks is extremely difficult. Sealing or oiling, by contrast, is reversible — a sealed floor can be sanded back and repainted or re-sealed at a later date with relative ease.

Painting is appropriate where the parquet has significant surface damage — discolouration, staining, uneven colour from missing blocks that have been replaced, or a general appearance that cannot be improved by sanding alone. A painted floor also makes a strong decorative statement and is historically appropriate: painted timber floors were common in Georgian and early Victorian interiors, particularly in secondary rooms and upper floors.

Sealing or oiling is appropriate where the timber is in reasonable condition and the natural grain and colour of the wood are worth preserving. A well-sanded and oiled oak parquet floor in a London townhouse has a warmth and authenticity that paint cannot replicate.

Preparation: The Critical Stage

Regardless of whether you are painting or sealing, preparation is everything. A parquet floor cannot be painted or sealed over old wax, old varnish, or contaminated surfaces. The existing finish must be completely removed.

For most London period parquet floors, this means mechanical sanding. A professional floor sander — either a drum sander for the main field or a belt sander — will remove the existing finish and a thin layer of timber to reveal clean wood beneath. This process generates a substantial quantity of fine dust and requires the room to be sealed off from the rest of the house.

Before sanding, walk the floor carefully and hammer down any raised nail heads or loose block fixings. A nail that sits proud of the surface will tear the abrasive belt, damage the sanding drum, and potentially cause injury. Check also that no blocks are loose or missing — these should be re-glued and allowed to cure before sanding begins.

Sanding Sequence for Parquet

Parquet presents a specific sanding challenge because the blocks run in multiple directions. Unlike a straight-laid board floor, you cannot sand with the grain for the entire field. A herringbone parquet in particular will have blocks running at 45 degrees to the room's axis, and the junction between blocks runs across the grain of adjacent pieces.

Professional floor sanders address this by sanding at 45 degrees to the herringbone pattern, then finishing with a fine grade along the dominant direction. The edge sander — used around the perimeter where the drum sander cannot reach — runs parallel to the skirting board. The junction between field and edge sanding should be blended carefully; this is where amateur sanding jobs most commonly show an obvious line.

Painting the Floor: Product Selection

For a painted parquet floor in a London period property, the choice of paint matters significantly. Standard wall emulsions and even floor paints designed for concrete will not bond adequately to prepared timber or will not withstand foot traffic. The correct products are specifically formulated floor enamels, deck paints, or specialist timber floor paints.

Farrow & Ball's Floor Paint is a popular choice for London period interiors — it provides a hard-wearing, low-sheen finish in their full colour range. Little Greene's Floor Paint is similarly durable. Both are water-based with sufficient hardness for normal residential use. For heavier traffic — a hallway, kitchen, or playroom — a two-component polyurethane floor enamel gives superior abrasion resistance, though it offers less colour choice and requires more careful handling during application.

Apply a minimum of two full coats, allowing each to cure fully before the next. Three coats will give a more durable finish. Lightly sand between coats with 240-grit paper or a fine scotch-brite pad to remove any nibs and improve intercoat adhesion.

Sealing the Floor: Oil vs Lacquer

Where natural timber is the goal, the two main options are oil and lacquer (varnish). Hard wax oils — products such as Osmo Polyx-Oil or Bona Hardwax-Oil — penetrate the timber rather than sitting on the surface. They give a natural, low-sheen appearance, are easy to spot-repair, and are particularly appropriate for period properties. The drawback is that they require re-application every two to four years in a high-traffic area.

Lacquers and water-based varnishes sit on the surface and form a film finish. They are more durable and require less maintenance but give a more obviously coated appearance and cannot be spot-repaired without visible joints.
