Intumescent Paint Contractors London

Professional Intumescent Paint Application in London

Fire Stopping London provides specialist intumescent paint contractors for structural steel fireproofing across London. Our certified applicators deliver precise fire-retardant coatings for commercial and selected residential projects requiring 60, 90, or 120-minute fire resistance periods.

What is Intumescent Paint?

Intumescent paint is a fire-retardant coating that swells when exposed to heat, forming an insulating char layer that protects structural steel from fire. This expansion can be up to 50 times the original coating thickness, maintaining steel integrity during fire exposure.

Our Intumescent Paint Process

Every project begins with structural steel assessment and specification review. We calculate the required coating thickness based on section factor, fire resistance period, and test data from certified systems.

Steel surfaces are prepared to the specified standard, typically SA2.5 blast cleaning for new steel or thorough cleaning for existing structures. Primers are applied where specified, followed by the precise application of intumescent basecoats.

Each coat is measured using dry film thickness gauges to ensure compliance with manufacturer specifications. Top coats are applied to the specified colour and finish, with full documentation provided for building control approval.

Commercial Project Experience

We have delivered intumescent paint fireproofing for diverse commercial projects across London, including office developments, retail centres, hospitality venues, and industrial facilities. Recent projects include nightclub steel fireproofing where aesthetics and fire protection are equally critical.
