Contego IFRM coatings continue to lead the intumescent fireproofing industry, pushing the standards higher with each test result. Contego HS RFB intumescent coating was tested December of 2023 at Intertek Laboratories in Elmendorf, TX achieving a new CII/IF 120-01 listed design.
Design No. CII/IF 120-01 encompasses the following structural steel:
Hollow Rectangular or Circular Structural Steel Columns: Use hollow steel sections, rectangular or circular shape, having nominal Hp/A or W/D section factors based on four-sided exposure to meet 1, 1 1-2, 2 HR Fire Resistance tested to ASTM E119, UL-263, CAN/ULC-S101 assembly ratings.
Save Time and Project Cost!
With 26 Hp/A listed data points, Contego’s design will cover your structural steel HSS Column needs with up to 30% less product and labor requirements. The chart below compares DFT (dry film thickness) coating requirements for a 2-hour fire resistance rating on HSS columns with the leading intumescent manufactures listed designs in the USA currently.

Contego is pioneering the (IFRM) intumescent fireproofing industry, pushing the standards higher with each test result. Testing the 1st 2HR UL D603 Composite Steel Deck Floor/Ceiling Design back in 2018, now testing the 1st Full Scale Dimensional Lumber Floor/Ceiling (13ft x 19ft OSB, I-Joist Assembly)
Location: Intertek Laboratories Test Date: 8.30.2022
The test specimen was tested load bearing with a 40 lb/ft2 superimposed load applied in four increments of 25% before the fire exposure, allowing for stabilization of deflection after each increment.
Contego HS Intumescent applied at a 40 Mil DFT on the Full Scale Dimensional Lumber Floor/Ceiling (13ft x 19ft OSB, I-Joist Assembly) 2×12 wood joists spaced 16-in. oc 23/32 Category OSB tongue and groove OSB subfloor with 7/8-in. Red Oak flooring planks, tongue and groove installed as finish flooring met a fire endurance period of 50 minutes before flaming was seen through the top of the sample.
When applying a finish coat to this assembly you will achieve an additional 16 minutes to total a 1:06 hour/minute fire resistance as per our ASTM E119/UL263 “The Effect of Top Coat on Contego HS Intumescent RFB” test results.
The specimen was evaluated in accordance with the following:
ASTM E119-20, Standard Fire Test Method for Fire Tests of Building Construction
CAN/ULC S101, Standard Methods of Fire Endurance Tests of Building Construction
UL 263, Standard for Safety for Fire Tests of Building Construction and Materials
The floor assembly consisted of the following:
13ft x 19ft overall area
2×12 wood joists spaced 16-in. oc spanning the 13-ft width. Center joist was a double 2×12. Fourth joist from the center in either direction was also a double 2×12 joist.
23/32 Category OSB tongue and groove OSB subfloor attached to wood framing with #9 deck screws spaced 12 in. oc.
7/8-in. Red Oak flooring planks, tongue and groove installed as finish flooring, fastened with 2-in. long brad nails. Three brad nails evenly spaced along width of each board at each joist location.
Underside of the floor assembly was primed with a water base interior and exterior primer.
Contego Passive Fire Barrier HS, Lot No. HS-1053, was sampled by Intertek’s Frances Martinez on June 28, 2022. This coating was first applied by brush along the wood seams. Then it was spray-applied in three coats. The coating was applied to the overall fire side of the sample with an overall average of 55.3 wet mils (39.8 dry mils).
100% silicone was used as filler between double joists. The silicone sealant was then coated with the Contego Passive Fire Barrier HS with brush application.
The assembly was then allowed to cure for 32 days before fire testing
The Contego International floor/ceiling assembly described within this test report met a fire endurance period of 50 minutes, as per the specified performance requirements of ASTM E119, Standard Fire Test Method for Fire Tests of Building Construction and Materials.
The test specimen was tested load bearing with a 40 lb/ft2 superimposed load applied in four increments of 25% before the fire exposure, allowing for stabilization of deflection after each increment. The full superimposed load was applied for 30 minutes before the start of the fire test.

When applying Contego intumescent paint, following the preparation and application guidelines developed over twenty years in business is a must.
If your preparation and application processes are in line with our published guidelines, Contego Intumescent will safely protect your project. We have created a series of six videos to help train your team. This first video explains how to safeguard your applicator, prepare the paint, and the type of equipment we recommend for our intumescent coating.
Contego comes in two thickness formulations:
The High Solids version (HS) has a 70% solids content and can be applied 30 mils wet, drying down to 21 mils. This preparation requires fewer coats to achieve a specified dry film thickness. Although thicker wet film coats can be applied with HS, the finish is essentially just as smooth as our Original version. The Original formula dries to approximately 50 percent of the applied amount. Due to its formulation, when the Original version dries, it is a bit smoother than HS.
The zero VOC content of both formulations has been demonstrated by testing ASTM D 3960-05, “Standard Test Method for Determining Volatile Organic Compound (VOC) Content of Paints and Related Coatings.” This makes Contego a safe coating for both the applicator and those who live within the structures protected by Contego.
The difference between HS and Original is that HS has less water and more thixotropy. Otherwise, comparison of the FTIR spectraflouriscopic “signature” of each version show they are chemically identical, so both offer the same class-leading fire protection.
HS is generally used on large projects, especially on structural steel columns and beams. These structures are often not visible when the project is completed, but that aside Contego is generally thinner, lighter, and less expensive than any other intumescent coating available. Plus, applying HS makes the job go faster because it requires less product and spraying. The Original version is usually used when spraying isn’t an option and brush and roll applications are the only choice. Both versions can be top-coated to add color or sheen and to seal the surface from wind and moisture.
Regardless of where these two outstanding products are applied, there is never an issue with the material when application instructions are followed. When we hear from an applicator that they are experiencing a problem with the product, it is almost always determined that it was caused by poor preparation or application.
We hope you find this first video explaining how to safeguard your applicator, prepare the paint, and the type of equipment we recommend informative. Other videos in this series will soon be available that cover related subjects.
Contego International started 20 years ago in a small family restaurant in Indiana and now draws in talent from around the globe. Contego’s intumescent products are sold worldwide and are applied to many types of surfaces, including steel, wood, aluminum, drywall, foam insulation, and concrete.
