This project involved the application of a passive fire protection system to structural steelwork as part of a community centre refurbishment. The works were undertaken to achieve a 60-minute fire resistance rating in accordance with the project fire strategy.
Due to the condition of the existing steel, full surface preparation was required prior to the application of any protective coatings.
All steelwork was abrasive blasted to remove existing coatings, corrosion and surface contamination, achieving a clean, sound substrate suitable for fire protection application. Particular attention was given to heavily corroded areas to ensure consistent surface quality across all members.
Following preparation, a zinc phosphate primer was applied to provide long-term corrosion protection and ensure optimal adhesion of the intumescent system.
Thermoguard WI intumescent coating was then applied by airless spray to achieve the specified dry film thickness required for a 60-minute fire resistance period. Application was carried out in accordance with the manufacturer’s data sheets and project specification.
Where required, a compatible flame-retardant topcoat was applied to provide a uniform finish and additional protection to exposed areas.
The completed system provides a durable, compliant passive fire protection solution designed to maintain structural integrity in the event of fire. All works were carried out to a high standard, with full quality control throughout the process to ensure long-term performance and compliance.
