Intumescent Coating — Passive Fire Protection for Structural Steel & Aluminium
Intumescent Coating is a water-based passive fire protection paint specifically engineered for structural steel and aluminium surfaces in commercial buildings, industrial facilities, and public spaces. On exposure to heat, the intumescent coating expands rapidly — forming a thick, insulating char layer that protects the steel or aluminium structure beneath, maintaining structural integrity for up to 90 minutes and providing critical time for safe evacuation and fire brigade response. Available at Saify Paint House — Karachi’s trusted industrial coatings dealer since 1999.
Why Choose Intumescent Coating?
Unprotected structural steel loses up to 50% of its load-bearing strength at temperatures of 550°C — a temperature that can be reached within minutes in a building fire. Intumescent Coating provides the passive fire protection that prevents this catastrophic structural failure, maintaining the integrity of steel and aluminium structures long enough for occupants to evacuate safely and for fire services to contain the fire. It is a mandatory requirement under Pakistani building regulations for commercial buildings, industrial facilities, hospitals, schools, and high-rise developments — and a critical investment in the safety of any building’s occupants and structure.

Surface Preparation & Application
Steel surfaces should be prepared to Sa 2 (light blast cleaning) or SSPC-SP6 standard and primed with a compatible steel primer before intumescent coating application. Apply intumescent coating in the number of coats required to achieve the specified dry film thickness for the required fire rating period. Apply by brush, roller, or airless spray. A compatible sealer or decorative topcoat can be applied over the cured intumescent coating to achieve the desired aesthetic finish. Always follow the product data sheet for film thickness requirements, recoat intervals, and fire rating specifications.
Industries That Rely on Intumescent Coating
Intumescent Coating is a mandatory specification across commercial construction, industrial facilities, healthcare, education, hospitality, retail, and high-rise residential sectors in Pakistan.
