Fire-Retardant Coating

Fire-retardant coating is a life-safety service that provides critical passive fire protection to building structures and elements, and Islamia Paints & Decor offers professional fire-retardant coating application for commercial, industrial, and residential buildings across Kolkata. Fire-retardant coatings work by either forming an insulating char layer when exposed to high temperatures (intumescent coatings) that slows heat transfer to the substrate, or by releasing fire-suppressing gases that dilute the oxygen and flame-sustaining chemicals around the fire (fire-retardant paints). Our fire protection services cover structural steel members (columns, beams, and connections in steel-framed buildings) that can lose their load-bearing capacity at temperatures as low as 550 degrees Celsius — intumescent coatings from Berger, Sika, and Asian Paints can provide 30, 60, 90, or 120 minutes of fire resistance depending on the coating thickness and system specified; wooden surfaces including doors, wall panelling, ceiling panels, and furniture where fire-retardant paints and clear intumescent varnishes reduce the surface spread of flame and provide valuable escape time during a fire; electrical cable trays and ductwork in commercial and industrial buildings where specialised fire-resistant coatings prevent fire from spreading along cable routes; and concrete surfaces in tunnels, parking garages, and industrial facilities where fire-resistant coatings protect against explosive spalling of concrete during a fire. Our application process follows strict manufacturer guidelines and relevant Indian standards (IS 3646 for fire-resistant coatings on structural steel). We begin with a thorough surface preparation (abrasive blasting or mechanical cleaning for steel, sanding for wood), application of a compatible primer, and then the specified number of coats of fire-retardant coating applied at the correct wet film thickness to achieve the desired fire rating. Every project includes thickness verification using dry-film thickness gauges and complete documentation for fire safety compliance. We serve commercial building owners, industrial facilities, hospitals, hotels, educational institutions, and residential developers across Kolkata.
