Intumescent Fireproofing — Toronto, York Region & GTA
Intumescent Fireproofing
Intumescent fireproofing is a thin coating that gives exposed structural steel a fire-resistance rating while keeping a clean, painted finish. FAIME applies it to beams, columns and steel decks in warehouses, industrial buildings and commercial conversions. Each coat is built up to the specified thickness, measured, recorded and handed over with the documentation.
Thin-film coatings applied to the thickness specified for each member's required rating.
Beams, Columns & Decks
Exposed interior structural steel, including mezzanines and steel deck undersides.
Measured & Recorded
Dry film thickness checked as the work progresses, with every reading recorded for your file.
A Decorative Finish
Steel stays visible and looks finished, which suits exposed structure in offices and showrooms.
What It Is
Looks Like Paint. Works Like Insulation.
In normal conditions an intumescent coating is a smooth, paint-like film. In the heat of a fire it swells into a thick, insulating char that slows the rate at which the steel heats up, helping the structure keep its load-bearing capacity for the rated period.
What FAIME Does
Thin-film intumescent coatings on exposed interior structural steel
Beams, columns, connections and steel deck undersides
Application by air spray and hand roller in measured coats
Dry film thickness inspections, recorded and handed over
Work phased around buildings that stay in operation
What Sets the Rating
The required rating for each member comes from the project's fire-protection specification
The specified product and its listed thickness for that steel section determine the build
FAIME applies to that specification and records the readings; it does not design the rating
We apply thin-film intumescent coatings, not cementitious spray fireproofing
How We Do It
The Thickness Is the Rating.
01
Site Assessment
We walk the building against the drawings and specification to confirm every member to be protected and its required rating, and coordinate access with the client and other trades.
02
Surface Preparation
Steel is cleaned and prepared so the coating bonds properly. Everything that is not being coated is masked and protected from overspray.
03
Built Up in Coats
The coating is applied by air spray and hand roller in multiple coats, each left to cure — typically around eight hours — before the next goes on. One heavy pass is never the shortcut.
04
Measured as We Go
Dry film thickness is checked regularly on flanges, webs and connections so that every section reaches the thickness its rating requires, not just the easy-to-reach faces.
05
Recorded for Your File
Every reading is recorded. At handover you receive the inspection reports and the material certifications for the products applied.
06
Safe Around Operations
Work areas are fenced and controlled, crews work to site safety protocols with the right PPE, and applications are scheduled around the building's operations.
Proof
Fireproofing Work We Have Actually Done
A York Region warehouse in Newmarket, being upgraded so that office space can be added. FAIME applied Sherwin-Williams Firetex® FX5120 for a 1-hour rating and Firetex® FX5090 for a 2-hour rating to selected beams, columns and a 1,300 sq ft steel deck, in multiple coats roughly eight hours apart, with thickness verified and recorded throughout. March to April 2026, completed on schedule with zero safety incidents while the warehouse stayed in operation.
Before: bare steel mezzanine structure.After: columns, beams and deck underside coated.Coated frames across the bay.Firetex® FX5090, the 2-hour product, on site.
Mezzanines, new office areas and change-of-use work inside existing industrial buildings, where exposed steel needs a rating and the building cannot stop operating.
Commercial Conversions
Offices, showrooms and retail spaces with exposed structure, where a clean, painted finish matters as much as the rating itself.
General Contractors
A fireproofing scope priced from your drawings and specification, applied to the specified products and thicknesses, and closed out with the paperwork you need.

Common Questions
Frequently Asked Questions
A thin coating applied to structural steel that looks like paint under normal conditions. When exposed to the heat of a fire, it expands into a thick, insulating char that slows the rate at which the steel heats up, helping it keep its load-bearing capacity for the rated period. Unlike cementitious spray fireproofing, it leaves the steel visible with a clean, decorative finish.
Through thickness. The required rating for each member comes from the project's fire-protection specification, and the specified product has a listed dry film thickness for that steel section and rating. The coating is built up in multiple coats until that thickness is reached, and the thickness is measured and recorded as the work progresses.
We apply the product specified for the project. On our Newmarket warehouse project that was Sherwin-Williams Firetex® FX5120 for a 1-hour rating and Firetex® FX5090 for a 2-hour rating, both water-based, thin-film intumescent coatings for exposed interior structural steel.
Usually, yes. Work areas are fenced and controlled, surrounding areas and equipment are masked against overspray, and applications are scheduled around the building's operations. The Newmarket warehouse stayed in operation throughout our work there.
