Intumescent Spraying & Coating

Intumescent Spraying & Fire Protection Coatings

Invisible Protection. Visible Compliance.

At HK Fire Ltd, we deliver professional Intumescent Spraying and Coating services to protect structural steelwork and building elements from fire. Intumescent coatings are a highly effective and unobtrusive way to achieve up to 120 minutes of fire resistance, ensuring your project meets all legal requirements and safety standards without compromising design or aesthetics.

What Are Intumescent Coatings?

Intumescent coatings are passive fire protection products that are applied as a spray or paint to structural components—most commonly steel, timber, or concrete. In the event of a fire, the coating reacts to heat by expanding and forming a thick, insulating char layer, delaying the temperature rise of the substrate and maintaining its structural integrity.

Applications include:

Structural steel beams, columns, and frames
Timber elements (walls, ceilings, beams)
Soffits and concrete structures
Fire-rated partition systems and fire doors (with appropriate specifications)

Why Use Intumescent Spraying?

Achieve up to 30, 60, 90, or 120 minutes of fire resistance
