Fireproofing vs. Intumescent Coatings
The visible and technical differences between cementitious fireproofing and reactive intumescent coatings.
Start with evidence
Record the existing substrate, exposure, damage, access and previous work. Photographs are useful when they are labelled as actual projects or clearly identified as representative.
Define performance and constraints
Identify the required outcome, operating hours, adjacent finishes, ventilation, cure or drying time and documentation obligations before selecting a product.
Request a written scope
The proposal should identify preparation, repairs, materials, application limits, exclusions, protection and the party responsible for inspections or testing.
Verify before closeout
Review appearance, coverage, transitions and required records. Keep product and maintenance information with the property file.
Compare the design basis first
Ask the designer to identify the required assembly, structural element and exposure conditions before considering alternatives. A thin-looking finish and a textured spray are not interchangeable simply because both are described as fire protection. Obtain the relevant system evidence and review any substitution through the project process.
Compare installation and maintenance constraints
Record surface preparation, primers, finish requirements, access and inspection responsibilities for each option. Ask how future damage is assessed and repaired. Keep technical acceptance separate from appearance approval so an attractive sample does not inadvertently authorise an unsupported system change.
