Fire-resistant paints

Intumescent paints are often used to protect exposed steel, making it unnecessary to enclose the structure with fire-rated assemblies and saving valuable interior space. Why must special care be taken with construction tolerances around all structural elements using intumescent paints?

AnswerIn a fire, the paint intumesces and expands to protect the material. Adequate clearance must be taken into account to ensure proper fire-resistance will be maintained.
