Resistant Paints, also known as Intumescent Paints work differently to fire retardant paint rather than discharging a flame dampening gas they burn and swell up when exposed to fire. It has the effect of making an insulating coating that protects any materials from the heat generated by the fire. The prime major reason that makes intumescent paint a good choice for fireproofing is that it is appropriate for use on almost all structural building materials like Softwoods (pine, cedar, and larch), Medium Density Fiberboard, Hardwoods ( Like oak, ash, birch, and beech), Chipboard, Metal, Concrete, Plaster, and Plasterboard, Melamine faced sheet and Brick and Stone.
