This intumescent paint are those fire retardants that are used to protect any substance or building from catching fire. Intumescent fire retardant paint are widely used by professional painters who use them as a passive protection mechanism of the building against fire. The paint containing the intumescent when exposed to the flames of a fire expands to become a black foam or “char barrier” which can be almost an few mm thick and coats the surface that the paint has been applied to.
This char acts as a barrier that cuts off much-needed fuel to the burning fire and protects the underlying structures giving precious extra time for the evacuation of the occupants of a building and allowing fire fighters longer to arrive and quench the blaze so that the damage is minimized.

The conventional way for fire proofing to steel structure is used vermiculite spray which is more rough and thicker. The thickness of spray can be up to 50 mm thk compare with 3 mm thk on intumescent paint in some cases. The surface applied is rough and uneven, more fragile or easily crack or drop ( internal grade vermiculite) in loose particulars. The other aspect is the price of vermiculite spray is relatively cheaper if compare with intumescent paint.
