Fire Resistant Paint and Fire Retardant Coatings
Fire resistant paint is a passive fire protection system, not a finish. An intumescent coating sits dormant at a few hundred microns and, at around 200 °C, swells into an insulating char many times its original thickness. That char is what keeps structural steel below its critical temperature long enough for the building to be evacuated.
Structural steel protection
The required dry film thickness is not a single number. It is calculated from the section factor (Hp/A) of each member and the fire rating required — 60, 90 or 120 minutes. A column and a secondary beam in the same building will need different thicknesses. We supply the coating with a thickness schedule worked out member by member, not a blanket specification.
Fire retardant coating for wood
For timber panelling, plywood partitions, stage sets and false ceilings, fire retardant paint for wood reduces surface spread of flame so the finish does not become the fuel that carries fire across a room. Clear and pigmented systems are available where the timber grain must remain visible.
Cable and penetration protection
Cable trays carry fire between compartments as efficiently as an open door. Fire retardant cable coating, combined with proper cable fire barrier sealing at every wall and floor penetration, restores the compartment line that the cable route broke.
Application and verification
Surface preparation, primer compatibility and ambient conditions decide whether the coating performs. We supply the system with application method statements and carry out wet and dry film thickness checks, issuing a coating record that can be submitted with the fire NOC documentation.
