Contego Fire Retardant Paint & Primer - Multi-Purpose Intumescent - 5 gallons

Contego PFB is a full-bodied latex, single component coating 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. The product may also be used for conduit, decking and cladding.

General Guidelines for Application

• Dimensional Lumber - Up to 1 hour depending on the size of the wood and the thickness
  of Contego applied. (40 mils/500µ dft)
• Manufactured Wood - Up to 1 hour depending on the size of the wood and the thickness
  of Contego applied. (40 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)

Contego PFB 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're 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.
