ICC Spray-Applied Fireproofing Special Inspector

HoldPoint study map

Course outline

Unit and lesson titles below are HoldPoint original material. They are not an official exam bulletin.

1. Substrate and application conditions

   Fireproofing fails on the steel you could not see, in the weather you ignored, to a thickness nobody measured.

   • Approved fire-resistance designs and the assembly you are actually looking at
   • Substrate condition: mill scale, paint, oil and decking
   • Primer compatibility and the product data that governs it
   • Ambient conditions and the manufacturer’s application window
   • Mixing, water content and the material that left the hopper
   • W-shapes, tubes, decks and the different inspection problems
   • Patching of holidays before you ever measure thickness
   • Practice: six substrate conditions, six next steps
   • Unit review: Substrate and application conditions

2. Thickness measurement

   Thickness is a sampling-plan problem first and a gauge problem second.

   • Which thickness the design actually requires — by member
   • Measuring locations: flanges, webs and decks
   • Gauge method and the averaging rule the method uses
   • Low thickness: how much area, how you report it
   • Built-up thickness versus a single pass
   • Masked connections and steel that was never sprayed
   • Re-measurement after a patch
   • Practice: lay out a thickness survey on a bay
   • Unit review: Thickness measurement

3. Density and adhesion/cohesion

   Thickness that passes can still fail density or bond. They are different tests.

   • Density specimens: where, how many, how handled
   • Laboratory versus field density as specified
   • Adhesion/cohesion: method identity
   • Failed bond on a painted or oily substrate
   • Over-spray, rebound and material that is not the tested product
   • When a passing thickness accompanies a failing density
   • Retests after corrective work
   • Practice: classify eight results as thickness, density or bond
   • Unit review: Density and adhesion/cohesion

4. Sampling locations, deficiencies and repairs

   A patch is new work. Sampling that only hits easy steel is not a sampling plan.

   • Random versus biased sampling
   • Members that are hard to reach and therefore uninspected
   • Damage after inspection: trades, weather, occupancy
   • Repair materials that are not the original product
   • Firestopping versus SFRM — different inspections
   • Intumescent coatings as a related but separate system
   • Stop-work when the design assembly is not what was sprayed
   • Practice: write four deficiency entries
   • Unit review: Sampling locations, deficiencies and repairs

5. Records and coordination

   The thickness log, the density report, and the steel inspector who needs the fireproofing off a connection.

   • What a complete SFRM daily report contains
   • Design-number traceability on the report
   • Coordination with steel, welding and the building inspector
   • Covering fireproofing with finishes too early
   • Occupancy that starts before patches are retested
   • Closeout package for the fire-resistance assemblies
   • Photographs that prove member coverage
   • Practice: assemble a closeout checklist
   • Unit review: Records and coordination

6. Mixed review and exam navigation

   Stems that mix substrate, thickness and bond, and how to keep those tests from collapsing into one “it looks thick enough.”

   • How an SFRM stem hides the required test
   • Thickness items versus density items
   • The unused hourly rating number
   • Mixed set: primer, thickness survey and bond test
   • Timed retrieval across Chapter 17 and the ASTM methods
   • What you do not redesign
   • Final self-assessment
   • Handoff to steel and general requirements
   • Unit review: Mixed review and exam navigation

Who this roadmap is for

Special-inspection personnel preparing for the SFRM credential scope.

Always confirm the current ICC eligibility rules, exam outline, references, fees, and scheduling policies before purchasing materials or setting an exam date.

Study sequence

A controlled preparation roadmap

1. 01

   Verify the current program

   Start with the official source links below. Record the current outline, permitted references, eligibility rules, and any application steps that apply to your route.

2. 02

   Map the reference set

   Turn each published domain into a retrieval map. Practice where to look before trying to memorize isolated answers.

3. 03

   Build the SFRM core

   Study substrate readiness and application conditions alongside thickness, density, adhesion, and cohesion testing, then connect both to field decisions and documentation.

4. 04

   Practice under controlled timing

   Use short lookup drills first, then mixed review. Track missed concepts and slow retrievals separately so each can be corrected.

5. 05

   Recheck before exam day

   Return to the credentialing body for last-minute policy or reference changes. Do not rely on a third-party summary for current exam administration.
