Intumescent coatings are highly engineered fire-retardant paint systems applied to load-bearing structural steel. In the event of a fire, the extreme heat triggers a chemical expansion, swelling the coating into a thick, carbonaceous char layer. This insulating barrier slows heat transfer to the steel, allowing the structure to maintain its load-bearing capacity for the specified fire rating period.

Where intumescent paint is typically required

We regularly apply certified intumescent paint systems to structural steelwork across various Grantham and South Kesteven projects, including:

• Logistics hubs, distribution centers, and commercial transport depots
• Agricultural buildings, food processing plants, and storage facilities
• Retail developments, retail parks, and trade counter units
• Schools, colleges, and community public buildings
• Office developments, business centers, and light industrial units
• Residential apartment complexes and modern housing developments
• Steel-framed structural extensions and building conversions

Fire resistance periods and compliance

We apply certified thin-film coatings to meet 30, 60, 90, or 120-minute fire ratings, based on the building's design, height, and intended use. Our estimating team uses structural steel drawings and fabrication schedules to calculate the precise dry-film thickness (DFT) required for each steel section size.

Every application is executed in accordance with ASFP standards and manufacturer specifications. We perform wet-film thickness (WFT) monitoring during spraying and complete comprehensive dry-film thickness (DFT) checks upon curing. A full compliance certificate and thickness log are issued upon completion to satisfy Building Control and project handover requirements.

How projects are delivered on site

Our experienced spray teams coordinate directly with on-site project managers to ensure smooth execution. We carefully monitor environmental conditions (including humidity, steel temperature, and dew point) to ensure correct paint adhesion. Masking, containment, and overspray control are managed to protect adjacent trades and structures.
