Thermoguard Thermocoat S is an intumescent, solvent based paint system providing fire resistance to structural steel and cast iron of up to 90 mins with a minimum number of coats. A compatible decorative overcoat system ensures the system will enhance the building’s architectural and design features. Recommended for external exposed steel not subject to pooling water. For interior Universal Beams, Columns and other open section steel see Thermoguard Thermocoat WI Ultimate. For interior steel hollow sections, see Thermoguard Thermocoat WO Ultimate Thermoguard Thermocoat S works as the heat of a fire triggers a catalytic reaction, causing the expansion of an insulating char layer up to 50 times the paint thickness. This layer keeps the steel below its critical temperature, thus maintaining the structural integrity of the building.

Surface Preparation Steel and Cast Iron Steel and cast iron should be free from rust and millscale and primed with Thermoguard Steel Fire Paint Primer to 75 microns DFT (or alternative good quality anti-corrosive primer compatible with intumescent paints) in accordance with manufacturers instructions. Treat galvanised surfaces with Teamac Mordant Solution (T Wash) first before priming with Thermoguard Steel Fire Paint Primer. Thermoguard Steel Fire Paint Primer may be left without further overcoating or decorated with appropriate conventional paint where no fire resistance is required depending on level of exposure/environment. To Specify Dry Internal: Apply Thermocoat S in accordance with film thickness schedule supplied by Technical Department to acheive 30, 60 or 90 minute protection. Visible external exposed during construction or occasional modest damp internal areas: Also apply 1 good coat Thermoguard Flame Retardant Topcoat (available in Gloss or Eggshell finishes). Not suitable for: Areas subject to “pooling” water Wet or External Under Cover: Apply 2nd coat Thermoguard Flame Retardant Topcoat (available in Gloss or Eggshell finishes). Full External Exposure - Contact Technical Team on 0113 2455450 Application Thermocoat S may be applied by brush, roller or airless spray. To achieve the best finish in the shortest time, spray application is recommended.
