Passive fire protection splits into three working families, and specifying by habit rather than asset wastes money in one direction and safety margin in the other. The comparison is clearer than the marketing around it.
Cementitious sprays
Cheap per square metre, fast over big areas, and effective while intact, cementitious fireproofing remains common on older UAE plants and in commercial construction. Its weaknesses are physical: weight that structures must carry, cracking under vibration and impact, and the moisture gap that opens against steel, breeding corrosion under fireproofing that inspection teams discover decades later. Coastal humidity accelerates exactly this.
Thin film intumescents
For buildings, thin film intumescent coatings protect steel at paint like thicknesses and cellulosic fire ratings, preserving architectural steel lines. They are the default for exposed structure in commercial projects across Dubai, applied over compatible primers with certified thickness per section factor.
Epoxy intumescents
Hydrocarbon environments change the fire curve and the answer. Epoxy systems such as Chartek are certified against hydrocarbon pool and jet fire scenarios, bond structurally to blasted steel, shrug off weather and washdown, and add corrosion protection rather than concealing corrosion. Refineries, gas plants and offshore assets specify them as standard, and our process plant fire protection article covers the detail.
The selection grid
Office and retail steel: thin film. Sheltered industrial structure with cellulosic risk and a tight budget: cementitious, with an inspection plan. Hydrocarbon facilities, coastal and offshore assets, and anywhere corrosion under fireproofing has been found before: epoxy intumescent, first and last.
