What kind of substrates can Contego be used on?
Contego has been proven effective on a wide array of substrates such as structural steel, wood (both dimensional lumber and manufactured woods like OSB, MDF, Plywood, etc), and drywall, spray polyurethane foam, aluminum, PVC pipe and more. It should not be applied on Stryofoam or EPS since that material is liquid fuel at less than 200 degrees and Contego, like ALL intumescents, reacts at about 360 degrees.
