Fire protection coatings expand when exposed to heat, forming a carbon-based char that insulates steelwork and delays structural failure. We deliver both thin-film intumescent coatings for exposed steel and cementitious sprays for high-demand environments such as data centres, plant rooms and warehouses.
Our approach combines rigorous surface preparation, accurate film-thickness measurement and full traceability throughout the process. We work with leading systems including Nullifire, Sherwin-Williams, Hempel and Jotun, ensuring every coating performs exactly as tested.
What sets us apart:
– Fully trained applicators with manufacturer approval for leading systems
– Controlled environmental application for accuracy and performance
– On-site film thickness testing and QA verification
– Full traceability from primer to top coat with digital documentation

An intumescent coating is a specialist fire protection paint that expands when exposed to heat, forming a protective char layer that insulates steelwork and delays structural failure during a fire.
Intumescent coatings are typically thin-film paints suitable for visible or architectural steelwork, while cementitious coatings are spray-applied for heavier-duty applications requiring higher durability or thicker coverage.
Depending on system type and thickness, coatings can achieve fire resistance ratings of 30, 60, 90 or 120 minutes, verified through testing to BS 476 Part 21 and EN 13381 standards.
Which manufacturers’ systems do you apply?
Yes. We offer both on-site and off-site applications depending on project requirements, size, and logistics. Each is delivered with full QA inspection and certification.
Every coating project includes digital QA records, dry film thickness testing, and photographic verification, supporting Golden Thread compliance and long-term maintenance planning.
