How to Buy Fireproofing for Construction Projects
Spray-applied fireproofing is a narrow, specification-driven channel. Two manufacturers dominate sprayed fire-resistive material (SFRM): GCP Applied Technologies with Monokote and Isolatek with Cafco, and both sell through a short list of specialty distributors to applicator subcontractors, many of whom hold manufacturer training credentials. Intumescent coatings for exposed steel follow paint-industry channels through companies like Sherwin-Williams and PPG alongside the SFRM makers. GCs never buy this material themselves; they buy an installed system from an applicator, because the product, the UL design, and the application equipment are inseparable. Board and wrap systems for joints and ducts move through commercial drywall distributors.
SFRM sells by the bag, with coverage math expressed in board feet per bag at a given thickness and density, and installed pricing quoted per square foot of protected steel at the thickness each UL design requires. Intumescent coatings price per gallon with dramatically higher material cost but a thin, paint-like finish. Applicators buy on net-30 distributor accounts with project pricing on bag counts in the thousands. Material pricing has moved up moderately into 2026 with gypsum and cement inputs, while intumescent products carry the steeper increases, reflecting resin costs and booming demand from exposed-structure architecture and mass timber projects.
Vetting in fireproofing means vetting the applicator and the paperwork chain together: confirm the sub is trained or approved by the manufacturer whose product is specified, that the exact UL or Intertek design numbers for your assemblies appear on the submittals, and that thickness and density testing will be documented per AWCI Technical Manual 12-A for the special inspector. Substituting products between bid and buyout requires re-approval against every listed design, so lock that early. Ask suppliers about regional stock depth during winter heating season, bond-test requirements over primed steel, and patch-material availability for the trades who will inevitably knock spray off beams.
Fireproofing Supplier FAQs
Can a general contractor buy SFRM and spray it in-house?
Legally in most places, yes; practically, no. The material requires specialized pumps and nozzles, manufacturer-trained operators, and installed thickness and density verified by special inspection against UL designs. A failed density test means stripping and respraying at your cost. Every serious project uses a specialty applicator, and manufacturers support trained firms with the technical documentation inspectors demand.
What is the difference between SFRM and intumescent fireproofing?
SFRM is a cementitious or fiber spray applied thick, cheap per square foot, and left concealed above ceilings. Intumescent coatings look like paint and swell into an insulating char in fire, making them the choice for architecturally exposed steel, at several times the installed cost. The fire-resistance rating requirement is the same; the difference is appearance and budget.
Why does the fireproofing thickness vary beam to beam?
Required thickness depends on each member's size, expressed as its W/D ratio, and the hourly rating of the assembly, so a light beam needs more material than a heavy column for the same rating. The applicator's submittals map every member size to a thickness under the governing UL design, and inspectors gauge-test against that schedule.
How is fireproofing repaired after other trades damage it?
Patching with the same manufacturer's material is standard and expected; hangers, duct straps, and conduit installers knock spray loose on every job. Keep bags of the specified product on site, document patches, and have the applicator return before ceilings close. Mixing a different brand into patches can void the tested design, so match the original product.
