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.

Are you in line with the global initiative to build and maintain a better, safer environment? Air Quality in the work environment – hospitals, schools, offices, commercial and residential buildings – is a big area of concern.
Clumpy, toxic cementatious coating
The WELL Standard* states“Pollutants generated indoors can lead to a variety of symptoms and health conditions. Volatile organic compounds (VOCs), combustion byproducts and airborne particulate matter are known to trigger nausea, headaches, asthma, respiratory irritation and allergies. While ambient outdoor air is often better quality, natural ventilation methods, operable doors and windows, and general building envelope infiltration can diminish indoor air quality if external air quality parameters are poor.”

A recent report from Mount Sinai Irving J. Selikoff Center for Occupational & Environmental Medicine Work Safely with Spray-on Fireproofing states:
Those who burn, prepare, grind, sift or sell [gypsum] are, as I have often observed, afflicted with great difficulty breathing… -Bernardino Ramazzini
Big changes in intumescent technology made “green” fire retardant paint possible. Contego intumescent changes fireproofing from the LEED nightmare associated with most fire protection products to a valuable LEED points generator.
You might know the history; environmentally friendly fireproofing was an oxymoron. Most fire retardant paint formulas were toxic, carcinogenic, and laced with high concentrations of VOCs. Those products are poisonous in the can and on the surface. This translates to very toxic in burn conditions.
HAZARDS IDENTIFICATION
Caution!
Causes eye irritation
Causes skin irritation
Causes severe respiratory tract irritation May cause risk of lung disease (i.e. silicosis and/or lung cancer)
Clean latex-based, non toxic intumescent coating
Do we really want to use this obsolete technology in our hospitals, schools, commercial & residential buildings?
Pressure treated fire resistant lumber (PTFR) is among the worst. According to USDA studies, the PTFR process is destructive to the lignins in the wood and would dissolve attachments, like screws and nails, unless they are stainless steel.
Then there are cellulosic and cementatious fireproofing materials. We’ve all seen them; they look like oatmeal when applied. The litigation list concerning these materials is lengthy and focused primarily on the constant deposition of tiny fibrils that get into the breathable air and are then inhaled straight into the lungs. Complaints in the majority of lawsuits have been centered on mesothelioma and other forms of cancer involving the respiratory system. In addition, when reading the MSDS of most intumescent coatings, the section on health risks contain clear warnings of both acute and chronic brain damage and damage to the central nervous system. Not exactly environmentally friendly.
The reason for these unhealthy toxic problems is simple. The components that make various fireproofing technologies work— whether cellulosic spray-on materials, cementatious products, mastics or intumescents—are inherently unhealthy.
This was one of the big drivers when Contego began designing cutting edge solutions for the green market niche. The challenge was to find alternatives that performed as well or, in most cases, better than what was already out there, without the risks from the past formulations. This research led to our current formulation of ZERO VOCs (ASTM D4017) and ZERO TOXINS (BSS 7239-88).
Contego meets all the Benchmarks for LEED certification, Living Building Challenge, WELL Standard and Google Red List Material Standard.
GREEN isn’t the only advantage of Contego Fire Barrier Intumescent Latex. It applies at a fraction of the thickness (and weight) needed for a latex intumescent in the past. It’s finish is as smooth as paper, pure white in color and is formulated to accept any topcoat.
That’s why we at Contego say…”White is the new Green”. Air Quality in SFRM fireproofing materials are a PROBLEM, Contego’s IFRM fireproofing is the SOLUTION! Get more information here.
