Earl’s Court Station

By 2007, the roof structure at the station needed refurbishment, which involved removing the existing paintwork and preparing the exposed steel before recoating.  This work was complicated however by the fact that the station had to remain open, and that there were up to 8 layers of old paint to be removed, some of which contained lead, and as the roof glazing had to be removed for this work, the coating system used would need to be fast drying at lower temperatures.

Experts at Sherwin-Williams worked throughout the project with the applicator, CLC Contractors Ltd, to develop a system that could be applied on site and meet the requirements of the project and the client, London Underground (TFL), who needed 15 years to first maintenance for the steelwork.

The solution was to chemically strip the old paintwork and then prepare the steel to St3 standard, apply a surface tolerant epoxy system of, Macropoxy M902 brushing aluminium primer and Macropoxy M905 undercoat, followed by Acrolon C137V2 acrylic urethane gloss topcoat.

Outcome

These epoxies have fast cure at low temperatures, and the topcoat gives long term protection thus allowing the work to be carried out to the required specification with minimum disruption to the normal station operation.
