Fireproof painting (intumescent coatings) protects structural elements from reaching critical failure temperatures during a fire. The coating expands dramatically under heat, forming an insulating char that protects steel from reaching 550°C — the temperature at which steel loses structural integrity.
Smooth applies intumescent coatings throughout the Boston area for commercial construction, multifamily residential, and restaurant/hospitality projects where exposed structural steel requires fire protection without spray-on fireproofing. We work with UL-listed systems to achieve code-required 1, 2, and 3-hour fire ratings.
Available for all standard code-required fire resistance periods
Allows exposed structural steel to remain architecturally visible
Fully documented and tested for code compliance
Thin-film for visible applications, thick-film for maximum rating requirements
Required fire rating and substrate conditions confirmed. UL-listed system specified.
Steel cleaned and primed per system requirements.
Intumescent coating applied in required passes to achieve specified DFT (dry film thickness).
Dry film thickness measured and documented for code compliance.
