Fire-resistant paints for steel
Thin films, serious protection
- Firefilm A6: white, water-based, low-thickness intumescent paint.
- Firefilm FC2: two-component system for steel structures.
- SC 902: two-component low-VOC system.
For concrete elements see fire-resistant plasters.
Frequently asked questions
Where are fire-resistant paints applied?
On steel columns, beams and trusses in factories, warehouses, shopping centres, car parks and public buildings where fire resistance is required.
Water-based or two-component?
Water-based intumescent paint suits interiors and is easy to apply. Two-component systems offer greater resistance to humidity and mechanical stress.
Can it be overpainted?
Yes, a compatible topcoat is usually applied for protection and colour. It must be selected per system instructions so intumescence is not affected.
How is thickness checked?
With wet and dry film thickness gauges during application. Thickness must match the fire protection design to achieve the required duration.
