We begin with a site visit to inspect the structural steelwork, existing coatings, surface condition and working environment. Our team reviews access requirements, surrounding areas, programme constraints and the required fire-resistance period. Where available, we also examine the project drawings, steel schedule and coating specification to establish the correct preparation method, compatible coating system and practical delivery plan.

Before work begins, surrounding surfaces and equipment are carefully protected, with suitable containment measures introduced where required. The steelwork is cleaned to remove rust, mill scale, failing paint and contamination. Where specified, we shot blast using iron silicate media to achieve an Sa 2.5 near-white metal finish. A compatible primer is then applied promptly to protect the prepared steel and provide a suitable foundation for the intumescent system.

The specified intumescent coating is applied using professional airless-spray equipment in a controlled sequence of layers. Application conditions and coating thicknesses are monitored to ensure the required system build is achieved across the steel sections. Once sufficiently cured, a compatible protective or decorative topcoat can be applied where specified, completing a durable passive fire-protection system designed for the project’s required fire-resistance period.
