PPG Architectural Coatings provided an extremely durable anticorrosive and fire protective coating system which met all British fire protection standards, while producing an attractive finish to complement Wembley Stadium's visual appeal.

PPG proposed and supplied the complete anticorrosive and fire protective coating system for all externally and internally exposed steelwork of the stadium. A combination of SIGMAFAST™ 302, SIGMACOVER 435, SIGMACOVER 456 HS and SIGMADUR™ 520 coatings were applied to the steel structures in order to provide a high level of anticorrosive protection.

For the required fire protection, a full three-coat fire system was used to meet the various environmental conditions around the stadium. The STEELGUARD 3146 primer and STEELGUARD FM560 solvent-based intumescent coating were chosen because they provide the required 60-minute fire rating. The topcoats used were STEELGUARD 2458 & AMERCOAT® 450SG to guarantee optimal aesthetics.

The STEELGUARD FM560 intumescent coating proved to be the best solution for the reconstruction of such an important landmark of sport infrastructure. Its fire and corrosion protection characteristics continue to meet British standards while retaining the aesthetic appearance of the stadium. They were successful in providing a solution that still protects the exposed steelwork for the arch, roof structure and internal steelwork for the bowl structure, and will do so for many years to come.
