Our Vermiculite Cementitious Coating is a spray- or trowel-applied fire-resistive system based on cementitious binder and lightweight vermiculite insulation, offering a reliable, fire-resistance rating of up to 4 hours for structural steel, decking and concrete substrates. It is especially designed to provide passive fire protection for different types of structures and equipment in Cellulosic fire enviroments, hydrocarbon fire environments and jet fire environments.

Key Advantages

• Up to 4 hours fire-resistance: Our product range has been tested for fire rating and can achieve designs with up to four hours of protection.

• Three density options – low, medium, high:

• Lightweight yet structural: The vermiculite-based composition adds thermal insulation to structural steel and helps maintain temperature below critical thresholds during a fire.

• Non-combustible, cementitious formulation: Free from intumescent coatings’ reliance on additives, this system is based on Portland-cement/vermiculite or gypsum/cement blends — providing passive fire protection through insulation rather than expansion.

• Versatile application: Spray or trowel-applied on steel beams, columns, ducts, metal decking, and suitable concrete or mixed substrates. It supports interior and semi-exposed usage depending on density selection.

• Durability and finish: Especially at medium and high densities, the system offers good abrasion¬- and moisture¬-resistance and for outdoor/exposed use is weatherable, freeze/thaw resistant and suitable for parking garages, exterior structures and clean-room environments.

Typical Applications:

• Structural steel fire protection in commercial, industrial, and high-rise buildings.

• Parking garages, transport terminals, and elevator shafts, especially where humidity or abrasion may be present.

• Exterior steel frames, exposed structural elements, and clean rooms.

• Spaces with high fire-risk in industrial settings.

Technical & Application Summary:

• Fire-Resistance Rating: Up to 4 hours (achieved with appropriate thickness and density).

• Application: Mix on-site with potable water and apply using conventional spray or pump equipment. Follow substrate preparation and thickness guidelines as per manufacturer data sheets.

• Finish: Natural concrete/grey textured finish. Can be over-coated if an aesthetic top coat is required.
