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.

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.
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.”
READ THE MSDS of the Products being used on your project. When considering required fire protection, old technology such as Spray Fire Resistant Materials (SFRM) may not meet all or any of these acceptable conditions:
October 2, 2018
- Formaldehyde levels less than 27 ppb.
- Total volatile organic compounds less than 500 μg/m³.
- Carbon monoxide less than 9 ppm.
- PM₂.₅ less than 15 μg/m³.
- PM₁₀ less than 50 μg/m³.
- Ozone less than 51 ppb.
- 0Radon less than 0.148 Bq/L [4 pCi/L] in the lowest occupied level of the project.
- Carbon monoxide levels less than 35 ppm.
- PM₂.₅ less than 35 μg/m³.
- Nitrogen dioxide less than 100 ppb.
- Formaldehyde less than 81 ppb. (more…)
Are you concerned about the future of projects where cementitious or cellulosic fireproofing has been applied? You should be.
An interesting set of recommendations and precautions has been offered by Mt. Sinai Hospital in New York (link to download at end below). In addition to Mt. Sinai, other major medical entities worldwide are identifying the fireproofing materials that many refer to as “oatmeal” as a probable source of various pulmonary disorders.
This is because these types of fireproofing materials are highly friable. Grab a section and pull it off. It typically isn’t hard to do. Note all of the fine particulate that breaks off with the section. When you consider how much of that “oatmeal” material gets shed into the breathable air, it’s no surprise that medical problems could ensue.
The good news is the human body is resilient. However, concerns were originally raised in a study from 1988 by the USDOC and NIST regarding SFRMs (Spray-On Fire Resistant Materials) containing asbestos and others that didn’t. It also discusses both SFRMs and insulation materials, so it should be clear that each product has to be evaluated on its own merits (or risks).
That same particulate is in the air as you can see by how much of it settles out on every surface in a structure. Once you breathe it in, it going to be in your body forever and potentially the source for a wide range of medical problems like COPD and mesothelioma. These and other diseases can cause respiratory impairment or even fatalities.
Perhaps that’s why many materials require everyone to leave the premises except the applicator. Then the applicator has to wear the “space suit” when working with those materials. This also causes massive scheduling delays and costs. One major GC in Las Vegas who primarily does nothing but projects valued at $120M+ said delaying his project by a month costs him $10M that he can never recover. Even a two week delay is obviously a $5M ding.
Carefully think about the materials you specify and use. Ask for an MSDS or SDS and read them. If many people read the MSDS or SDS documents, a lot of these products would be history.
Use a latex based intumescent coating like Contego. It is zero VOC and offers the same or better protection as cementitious or cellulosic without the possible associated medical outcomes down the line.April 26, 2018
Contego Reactive Fire Barrier Intumescent paint has been chosen to protect the frame structures of the 48 elegant passenger capsules incorporated into the worlds largest and tallest observation wheel the Ain Dubai (Dubai Eye in English).
The passenger “pods” were designed and built by Molinari Rail of Switzerland. The steel and aluminum structures of the 48 capsules will be prepared, primed, coated with Contego High Solids Reactive Fire Barrier (RFB) then top coated. The Contego RFB application process will be handled by S.C. Omega Solutions Center S.R.L.
The Ain Dubai will be the world’s largest giant ferris wheel. It is located on the $1.6 billion dollar Bluewaters Island development, off the coast of Dubai’s Jumeirah Beach Residence, with a projected 2018 completion date. The 48 luxury capsule “pods” of the wheel will be capable of holding 1,400 visitors at any given time and offer views of Dubai’s iconic landmarks.
Over 210 meters tall, the Ain Dubai, will eclipse the 167-meter High Roller in Las Vegas and the 190-meter (625ft) New York Wheel to be built on Staten Island. The final structure of the Ain Dubai will include around 9,000 tons of steel, almost 25 percent more than the amount of iron used to construct the iconic Eiffel Tower.
Two of the world’s largest cranes, each with a 180-meter-long boom (590 ft) and the capability to lift more than 3,000 tons are used to raise this remarkable structure. For reference, that’s a lifting capacity of close to 11 Airbus A380s. The assembled hub and spindle stretch 40 meters (130ft) across and 20 meters (65ft) high, weighing a total of 1,805 tons.
Speaking of the Ain Dubai, Omar Delawar, Chief Projects Officer at Meraas, said: “Once completed, Ain Dubai will emerge as an engineering masterpiece, the first of its kind in the industry.”
Abdulla Al Habbai, group chairman at Meraas, said: “Ain Dubai reflects our ambition of creating new destinations that contribute to His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of UAE and Ruler of Dubai, vision of a city where people are encouraged to create, explore and enjoy.”November 29, 2017
Contego’s New D603 Floor Ceiling Assembly from UL Finally Puts An End to The Cementitious Nightmare for Fireproofing Decks
Contego has been famous for cutting-edge super thin film intumescent technology – and now has a UL intumescent deck assembly for corrugate pan decking that exceeds two hours! Contego is thin, light, smooth, green and affordable as well.
As Mel Martin, in charge of Contego’s Canadian Business Development, says “It’s not a question of if it [cementitious fireproofing] will fall off, but when.”
Contego’s adhesion of 631 PSI, according to our ASTM D4541 test, is twice that of our one closest competitor and between ten and fifteen times better than most of the rest.
Structural steel is protected with Contego’s thin film intumescent coating. You can see below the pervasive damage that spray-on fireproofing typically inflicts on steel.
Here’s a shot of the two types of fireproofing side by side on steel beams.
Of course, beams and columns also benefit from a thin film intumescent, but more on that in another post.
For now, would you prefer this:
Or would you prefer this:
Historically, there were no options beyond cementitious. SFRM (Spray-Applied Fire Resistive Material) was the only way to get a rating on deck systems. No more. In the past, the only other reason to continue using SFRMs was because they were perceived as being cheap. Now people are finding severe damage to their structures where SFRMs have been applied. Some damage so bad that the building can’t be spared and people are realizing a lower initial cost is a terrible bargain just a few short years down the road.
With the medical community also warning against the use of SFRMs, the potential legal liabilities make SFRMs the last thing you should use.
Now all of that has changed. For those who like UL, our new D603 intumescent deck assembly clears the way to an astonishingly thin and smooth coating that can be top coated to unleash a world of creative options.
Just as important, after reviewing the raw data, the Contego intumescent deck assembly was nowhere near failure at 2 hours, so the real rating is well beyond that mark. In the near future, we will run the same test extended to three or four hours as well as a very thin coat that is consistent with our ASTM-E119, UL-263,ULc-S101 test done at Intertek in 2009.May 8, 2017
