Fireproof Paint for Steel | Contego HIGH SOLIDS Fire Retardant Paint/Primer for Steel (1-3 Hours) - 5 gallons
What is this Fire Resistant Metal Paint?
Specially designed for structural steel, the new Contego High Solids formula means you can get the same great results using 20% less paint! A thinner coat means less labor costs to get the desired rating. Full-bodied latex, single component coating is designed to protect a wide range of building materials, including structural steel, aluminum, dimensional lumber, manufactured wood products, trusses, drywall, spray polyurethane foam insulation, HDPE wall panels, concrete, plaster, solid core doors and more. “HS” (High Solids) provides an alternative to Contego’s ORIGINAL FORMULA product. At 68% solids, the HS variant requires one-half to perhaps one-third as many coats. It must be applied with a spray gun with 3,300 psi (216 Kg/cmC) or greater with an 0.025″ (0.62mm) tip or larger.

- Interior or exterior application (just use exterior grade top coat for exterior applications).
This fire rated paint for steel should not be applied when the relative humidity exceeds 80% or the surface to be coated is less than 40°F (5° C) or less than 15°F (-9°C) above the current or forecasted dew point. The product is best applied when ambient temperatures are between 50°F (10°C) and 95°F (35°C). While the product can be applied at lower temperatures, viscosity may be a problem and, if applied at higher than recommended temperatures, there may be a risk of runs or sags. Once applied and cured, extremely low or high temperatures should not be a problem.
On combustible substrates such as dimensional lumber, manufactured wood (Oriented Strand Board, Particle Board, Plywood, etc.), polyurethane foam, and drywall (GWB) a primer is not required but may be useful if:
- Dimensional Lumber - The wood is very old and/or dry and would likely absorb too much of the Contego coating.
- Manufactured Wood - The substrate is very old and/or dry or if the resin content is unusually high.
- Polyurethane Foam - The foam is soy-based or made from other organics that emit a vegetable oil.
- Drywall (GWB) - The drywall has been previously painted with oil-based (alkyd) paint or if you are not sure.
On structural steel and other metals such as aluminum, copper, brass, or composites, a primer is always required. No exceptions have been observed regarding what kind or brand of primer can be used. Even inexpensive shop primer has shown no incompatibilities. However, doing a test patch is always recommended with any new combinations of primer and our product since it is impossible to have tested every product from every manufacturer.
Thickness and Coverage Rates - this depends entirely on the substrate and the time rating required. Please call to get coverage requirements for your particular project.
General Guidelines for Coating Thickness Requirements
- Dimensional Lumber - Up to 2 hours depending on the size of the wood and the thickness
of Contego applied. (20 mils/500µ dft)
- Manufactured Wood - Up to 2 hours depending on the size of the wood and the thickness
of Contego applied. (20 mils/500µ dft)
- Polyurethane Foam - Meets the 15 minute thermal barrier requirements of IBC-2603.
(15 - 20 mils/380-500µ dft)
- Drywall (GWB) - Contego adds 55 minutes to any type of GWB. (15 mils/380µ dft)
- Structural Steel - Contego provides up to 3 hours restrained depending on the W/D, Hp/A or A/P of
the steel and the thickness of Contego applied. (8 - 200 mils / 200-5000µ dft refer to our steel calculator
- Aluminum Columns have been tested for 2 hours. Aviation grade .025 panels for an estimated 4+ hours. (20 - 50 mils/500 - 1270µ dft)
