Thermoguard Steel Fire Paint Primer is a quick drying, high build, solvent-based primer for structural steel offering exceptional corrosion resistance, maximum grip to steel and existing primers and helps to ensure good intumescent paint adhesion.

Ideal for priming bare steel surfaces before the application of Thermocoat WI, Thermocoat WO and Thermocoat S intumescent paints. Also suitable for application where corrosion resistance is required in normal buildings or as part of a corrosion resistant system when overcoated with Thermoguard Flame Retardant Paints.

Designed for structural steel frames requiring full or partial fire protection with Thermocoat intumescent paint.

Thermoguard Steel Fire Paint Primer is composed of Zinc phosphate and Micaceous Iron Oxide for exceptional corrosion resistance and adhesion.
