Painting Lift Doors: The Complete On-Site Spraying Guide

Lift doors are one of the most visible and most-touched surfaces in any office block, hotel, hospital, or shopping centre. Scratches accumulate from trolleys and luggage. Scuff marks build around door edges from daily foot traffic. Painted or powder-coated finishes fade unevenly under harsh lobby lighting. And yet the lift itself may be in perfect mechanical order, replacing doors to address a cosmetic problem is an expensive, disruptive, and entirely unnecessary response.

On-site electrostatic spray painting is the practical alternative. It restores the surface to a consistent, durable finish in a single overnight session, at a fraction of the cost of door replacement, with no structural work and no extended lift downtime.

Why lift doors degrade faster than most interior metalwork

Lift landing doors face a combination of mechanical abrasion and environmental stress that accelerates finish degradation. The door edges and frames are struck repeatedly by trolleys, cases, and hand trucks during loading. Door faces are touched thousands of times a day by people steadying themselves as doors open and close. In environments with high foot traffic, hospitals, hotel corridors, supermarket back-of-house, the finish can show visible wear within two to three years of installation.

In buildings where the interior has been refurbished, original lift door colours also frequently fall out of step with new wall finishes, floor coverings, and reception schemes. A fresh colour is often needed not because the surface is damaged, but because the scheme has moved on.

Both situations, wear-driven degradation and aesthetic mismatch, are addressed effectively by on-site electrostatic recoating.

Why electrostatic spraying is the standard method

Electrostatic spraying works by electrically charging the atomised paint particles as they leave the spray gun. The lift door panels, which are earthed metal, attract the charged particles, causing them to wrap around edges and profiles rather than bouncing off or drifting away as overspray. This produces several important advantages in a lift lobby environment:

• Minimal overspray: Charged particles attracted to the target surface produce far less drifting spray than conventional airless or HVLP methods, critical when working adjacent to button consoles, carpeted floors, and decorative wall finishes
• Even edge coverage: The wrap-around effect ensures consistent film build on door edges and rebates, the areas most prone to thin coverage with conventional methods
• Fast application: The efficiency of electrostatic transfer means large areas of door panel are covered quickly, reducing time the lobby must be cordoned off
• Excellent adhesion to metal: The electrostatic bond between charged particles and earthed metal surface contributes to strong initial adhesion before chemical cure begins

For situations where electrostatic equipment is less suitable, such as very deep recesses within the door frame, or lift car interior panels with complex profiles, HVLP (high volume low pressure) spraying can be used as a complement. Both methods produce a factory-quality finish when applied correctly to a properly prepared surface.

How the process works: step by step

Every lift door recoating project follows the same methodical sequence. Shortcuts at any stage compromise the final finish, particularly in the preparation phase, where the quality of the cure adhesion is established before any topcoat is applied.

Recoating versus door replacement: a direct comparison

For building managers evaluating options, the comparison between on-site recoating and full door replacement is straightforward on cost and disruption grounds. The table below sets out the key factors.

Which lift door surfaces can be sprayed?

Electrostatic spraying is applicable to virtually all metal components associated with lift landing installations. In most recoating projects, the scope includes:

• External landing door leaves (the primary door panels visible to building users)
• Door frames and surround sections
• Side panels and pilasters adjacent to the door opening
• Header sections above the door
• Internal car door panels (using HVLP where electrostatic access is restricted)
• Lift car ceiling panels and wall panels (where metallic, interior wall finishes are assessed individually)

Glass inserts within door panels, button console face plates, and any digital display panels are masked off and not sprayed. Stainless steel lift doors with brushed or mirror finishes require a different assessment, where the existing stainless surface is in good condition, a metallic effect coating over it is an option; where genuine stainless panels are required, replacement is the correct route.

Colour matching and metallic finishes

One of the most common reasons building managers commission lift door recoating is to update the colour to match a refurbished interior. Lift lobbies that were last decorated in the 1990s or early 2000s frequently carry door finishes in colours, beige, oatmeal, pale grey, that look dated against modern interior schemes.

Any colour from the RAL Classic, RAL Design, British Standard 4800, or NCS range can be mixed and applied. Where a building has a specific corporate or brand colour, paint manufacturers can mix to a supplied colour reference or from a physical sample. Metallic topcoats, replicating the appearance of brushed steel, satin aluminium, antique bronze, or aged brass, are also available and are applied in the same electrostatic process.

Where a colour match to an existing adjacent surface is required, a paint chip or physical sample allows the correct BS or RAL reference to be identified before spraying begins.

Working in occupied buildings

The majority of lift door recoating projects take place in occupied commercial buildings, office blocks, hotels, hospitals, and residential apartment buildings where the lift serves active floors 24 hours a day. Electrostatic spraying is well suited to this environment because:

• Work is typically scheduled out of hours (evenings or weekends) to avoid lobby congestion during business hours
• The minimal overspray characteristics of electrostatic application reduce the risk of paint affecting surfaces beyond the masked zone
• The coating reaches overnight drying and handling strength, meaning the lobby is fully presentable before the building opens
• In multi-lift lobbies, adjacent lifts continue to operate throughout, so vertical access to the building is never fully lost

Where access restrictions or building management requirements make even brief overnight cordoning impractical, we discuss scheduling options with the client to identify a window, weekend, bank holiday, or annual shutdown period, when the work can proceed without inconvenience to occupants.
