How to Paint Stairs and Bannisters in London: A Phased Approach for Occupied Homes

The Staircase: London's Most Challenging Decorating Project

The staircase is the single most difficult element to paint in a London home. It is in constant use — often the only route between floors — and it encompasses a demanding combination of surfaces: hardwearing treads, delicate spindles, a smooth handrail, newel posts, string boards, risers, and the surrounding walls. Each of these surfaces has different preparation requirements, different paint specifications, and different drying time constraints.

In Belgravia townhouses and Chelsea terraces, staircases are often the most architecturally prominent feature of the hallway, with turned balusters, carved newel posts, and swept handrails that demand careful, detailed work. In more modest London properties, the staircase may be simpler in design but no less critical — it is the first thing visitors see and the surface that takes the hardest daily punishment.

Planning the Phased Approach

In an occupied London home, painting a staircase in a single continuous operation is rarely practical. The household needs to move between floors, and fresh paint on treads needs time to cure before it can take foot traffic. The solution is a phased approach:

Phase 1: Balusters, newel posts, and handrail — these can be painted first because they do not need to be walked on. The household can continue using the stairs normally while the balustrade dries and cures.

Phase 2: Risers and string boards — these vertical surfaces can be painted next, again without disrupting access to the stairs.

Phase 3: Treads — this is the critical phase. The most common approach is to paint alternate treads, allowing the household to use the unpainted treads for access while the painted ones dry. Once the first set is cured (typically 24–48 hours for a floor paint), the second set is painted. Some decorators paint one side of each tread, allowing foot traffic on the other side, but this is only practical on wider stairs.

This phased approach typically extends the project over four to five days, but it means the staircase is never entirely out of commission.

Paint Specification for Treads

Stair treads take more physical punishment than almost any other painted surface in a home. They are walked on in shoes, dragged across with furniture, and subjected to grit and abrasion that would destroy a standard wall emulsion within weeks.

The correct specification for painted stair treads is a dedicated floor paint — not a standard eggshell or satin. Professional options include:

• Dulux Trade Diamond Glaze — a water-based floor paint with excellent abrasion resistance and a satin finish
• Johnstone's Two Pack Epoxy Floor Paint — extremely tough, best suited to service stairs and utility areas
• Farrow & Ball Floor Paint — available in the full Farrow & Ball colour range, this is a hardwearing option for decorative schemes where colour coordination with the walls matters
• Mylands Floor Paint — popular among London decorators for its historical colour palette and tough finish

Whatever product is chosen, preparation of the treads is essential: existing paint must be sanded to a smooth, sound surface, bare timber must be primed with a wood primer, and dust must be removed completely before applying the floor paint. Two coats are the minimum; three coats provide significantly better durability.

Preparing and Painting Spindles

Staircase spindles — turned or square — are time-consuming to paint well. In a typical London terraced house, a single flight may have 30 to 40 spindles, each requiring individual attention.

Preparation: existing paint should be lightly sanded with fine abrasive paper or a foam sanding block, working around the profile of each spindle. If the existing paint is heavily built up, the spindles may need stripping — chemical paste is the safest method for turned profiles.

Application: spindles are best painted with a small brush — a 25mm or 38mm angle brush — working from the top down. The paint should be worked into the grooves and quirks of the turning first, then the flat surfaces smoothed out. A common mistake is to overload the brush, which leaves runs in the crevices. Thin, even coats are essential.

Product: a water-based eggshell or satinwood is the standard choice for spindles. It provides a smooth, hardwearing finish that resists fingerprints and scuffing from the hands that inevitably grip the balusters when ascending and descending.

The Handrail

The handrail is the most heavily touched surface in the house. Every ascent and descent involves prolonged hand contact, and the paint must withstand this without becoming tacky, discoloured, or worn.

Many London homeowners choose to leave hardwood handrails in a natural finished state — oiled, waxed, or varnished — rather than painting them. This is particularly appropriate for mahogany, oak, or walnut handrails in period properties, where the warmth and grain of the timber is part of the architectural character.

If the handrail is to be painted, a high-quality satinwood or gloss finish provides the best durability. The surface should be degreased thoroughly before painting — years of hand contact deposit oils that prevent adhesion — and the paint allowed to cure fully before the handrail is used. In practice, this means taping a temporary rope or fabric guide alongside the staircase while the handrail cures.

Walls and Ceiling Above the Stairwell

The stairwell walls above a London staircase present their own challenge: height. In a Victorian or Edwardian townhouse, the stairwell may rise through three or four storeys, with the upper sections accessible only from scaffolding or a stair tower.

Professional decorators use stairwell scaffold systems — adjustable platforms that rest on the treads and provide a level working surface at height — to reach the upper walls safely. This is not a task for a domestic stepladder; the geometry of a staircase makes unsecured access at height genuinely dangerous.

The walls should be painted in a washable emulsion — the stairwell is a high-traffic area and the lower sections will accumulate scuffs and marks. A mid-sheen finish is practical and easier to wipe clean than a flat matt.

Timing and Scheduling

In London, the best time to paint a staircase is during mild, dry weather when windows can be opened to provide ventilation and accelerate drying. Spring and early autumn are ideal. Winter projects are feasible but require longer drying times between coats and careful management of heating to avoid trapping moisture beneath the paint film.

A full staircase redecoration in a London townhouse — treads, risers, strings, balusters, handrail, newels, and stairwell walls — typically takes five to seven working days for a professional team.
