Tower Bridge Restored to True Colours

Published on 2009-09-30. Author : SpecialChem

Tower Bridge is one of London's best-known landmarks. But years of exposure to the harsh city environment means that the bridge now needs a facelift. Coatings supplied by Hempel UK will protect Tower Bridge for 25 years, and make sure it retains its iconic look.

Built in 1894, Tower Bridge can be seen in Hollywood films, tourist brochures and picture postcards. But after years of exposure to the elements, the bridge has lost its sheen - so a four-year renovation project costing £4 million is now underway.

Hempel UK is supplying the protective coatings, a total of 22,000 litres of paint, to ensure the bridge keeps its iconic blue and white colours for the next quarter of a century.

Restoration without disrupting traffic

A vital part of London's transport system, around 40,000 motorists and pedestrians use Tower Bridge each day. In order to cause as little disruption as possible, the work will be done in sections, with a quarter of the bridge under scaffolding at a time.

Protecting the environment

For this project, around 1,500 tonnes of abrasive material will be used to blast away old paint and reveal the original metal framework underneath. To protect the River Thames and the immediate environment, the bridge sections will be fully shrouded and the debris will be collected and safely disposed of.

Long-lasting protection

Hempel UK is supplying a state-of-the-art high-performance coating system that will protect Tower Bridge for at least 25 years. A variety of coatings will be used on different areas and sub-structures, and the coating system will be touched-up after 12 years.

The coatings protecting Tower Bridge

Shopprimer E 15280

A two-component epoxy polyamide primer containing zinc phosphate rust-inhibiting pigments

Hempadur Mastic 45880

An extremely robust two-component high-build epoxy paint with a high-solid content

Hempathane 55810

A low-VOC, two-component polyurethane topcoat with very good gloss and colour retention will ensure that the bridge looks its best when the work is done.

About the Restoration Project:

Pyeroy Ltd. is carrying out the restoration project on behalf of the City Bridge Trust, which maintains all five city bridges (London, Tower, Southwark, Blackfriars and Millennium Bridges) at no cost to the British taxpayer. Hempel UK is also supplying Pyeroy with 13,000 litres of protective coatings for the £2.5 million facelift of Southwark Bridge.
