Exteriors and weather

Coating external staircases and fire escapes safely

An external staircase or fire escape is a piece of safety equipment as much as a painted structure, and work on it has to respect that at every stage. Access cannot simply be blocked overnight, and the coating specified has to cope with foot traffic, exposure and the anti-slip requirement most of these structures carry.

Keeping the escape route usable throughout

We agree with the building's management how the route will be kept clear or how an alternative is signed during the work, since a fire escape cannot simply be closed without a plan agreed in advance with whoever is responsible for the building's safety.

Escape route status agreed with the responsible person before starting
Signage and temporary alternatives put in place where access is affected
Work phased by section so at least part of the route is always usable

Corrosion at treads, welds and fixing brackets

Open steel staircases corrode fastest at tread edges, weld seams and the brackets fixing the structure to the building, all points where water sits or vibration works a coating loose. These get specific mechanical preparation rather than a general once-over.

Anti-slip and coating compatibility

Many external staircases carry an anti-slip nosing or aggregate finish on the treads, and any coating chosen has to be compatible with that texture rather than filling it in and reducing grip. We check what is already specified for the treads before proposing a system for the rest of the structure.

Working at height on an occupied structure

Painting a staircase that people are actively using means careful sequencing, wet paint signage and sometimes out-of-hours working where the building's use pattern makes daytime access difficult.

Sections worked in a logical order to minimise closed time
Out-of-hours slots considered where daytime use is heavy

How we work on this

We agree escape route access with the responsible person before starting any staircase work
We give tread edges, welds and fixing brackets specific preparation, not a general once-over
We check anti-slip compatibility before specifying a coating for stair treads

Questions we are asked about this

Can a fire escape be painted without closing it?

Usually yes, if the work is phased so at least part of the route stays usable, with clear signage for any temporarily closed section. We agree the approach with the building's responsible person before starting.

Do you need to remove anti-slip surfacing to paint the treads?

No, we choose a coating compatible with the existing anti-slip finish so grip is not reduced. Where the anti-slip surface itself is failing, that is worth raising separately as its own repair.

How often do external staircases need repainting?

More often than most exterior joinery, since they take constant foot traffic and full weather exposure. A regular inspection cycle usually catches problems before they need a full strip-back.
