ROOFDX SUPER
Restores Corroded Metal Roofs. Heavy-Duty Waterproofing Protection.
ROOFDX SUPER is a high-performance, single-component urethane coating engineered to restore and protect heavily corroded metal roofs. Designed for demanding roofing applications, it penetrates, seals, and stabilizes deteriorated surfaces—forming a tough, elastic, waterproof membrane that extends roof life and reduces the need for costly replacement.
Formulated with corrosion-inhibiting pigments, ROOFDX SUPER actively protects metal substrates from rust, acid rain, and environmental attack. Its ability to react with existing corrosion allows it to expand into rusted areas, sealing crevices and reinforcing compromised sections for long-term durability. Its wetting and penetrating properties enable it to seal deep cracks and irregular surfaces, making it especially effective for aging and damaged roofs.
Once cured, ROOFDX SUPER forms a seamless, resilient barrier that prevents air and liquid penetration while maintaining flexibility under extreme temperature conditions. It offers excellent resistance to oils, fats, acids, and other pollutants, and can be used as a buried membrane beneath soil, pavers, or other overburden systems for versatile, long-term protection.

Technology
Moisture-Cure Urethane System
Preparation and Application
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion. Do not apply if the substrate or air temperature is predicted to drop below 35°F (2°C) within 4 hours after application. The application surface must remain at least 5°F (3°C) above dew point during the application and curing process.
Application
Do not apply ROOFDX SUPER to wet, damp, or frozen surfaces. Do not apply if the area cannot be protected from precipitation for at least 4 hours after application. ROOFDX SUPER is applied directly out of the container after at least 2 minutes of low speed drill stirring. Do not thin the product. Apply in 2 coats using a soft brush, medium nap roller, or airless sprayer in a smooth, even technique.
Application over Seams in Metal Roofs
Achieved by embedding ROOFAB into a fresh coat of ROOFDX SUPER applied at 15 mils wet thickness. The fabric is then saturated with a second application at sufficient thickness to remove all voids, fishmouths and dry spots. Bolt heads on metal roofs should be daubed with K-CATALYST modified ROOFDX SUPER until they are completely encapsulated. As soon as the K-CATALYST ROOFDX SUPER has set, it should be coated with a compatible topcoat.
Application over Built-Up or Modified Asphalt or Capsheet Roofs
Requires good preparation as described above. If gravel is present, this should be removed by wet-vac or scraped off and pressure washed. BUILDKOTE or compatible flood coat should be installed to soften the profile of embedded gravel.
Application of ROOFDX SUPER may proceed by embedding 40” ROOFAB into a fresh coat of ROOFDX SUPER applied 1½ gallons per 100 sq ft (66 sq. ft. per gallon); the fabric should be smoothed out without stretching so that it conforms to the surface without voids, tents or dry spots. Begin at the lowest point of the roof and each roll saturated with an even coat of ROOFDX SUPER at 1½ gallons per 100 sq ft (66 sq. ft. per gallon) as soon as the first coat has soaked up and no wrinkles remain. Enough material should be present at the overlap that saturation occurs completely without fishmouths or dry spots. Continue application with laps facing downhill to shed water if work is interrupted by precipitation. Sudden precipitation will not wash ROOFDX SUPER off when wet or newly applied, but will produce a mottled, dull appearance that is not detrimental to overall performance.
ROOFDX SUPER should always be coated with a suitable topcoat and if solar panels or other overburden is installed, use appropriate separation layer.
Spray Application
Utilize a 45:1 airless pump, a 1/2″ hose, 3/8″ whip and a 37 to 41 width tip
Recommended Thickness
30 mils Dry Film Thickness (DFT)
Drying Time
To walk on – Approximately 24 hours @ 80°F (27°C) and 70% RH.
Total Cure – Approximately 72 hours @ 80°F (27°C) and 70% RH.
Clean up
Clean tools and equipment with xylene or aromatic solvent.
Storage
Store in a dry area and protect from direct sunlight and freezing. Keep container tightly sealed. Shelf life is 2 years from date of manufacture when stored in a factory sealed container between 50ºF (10ºC) and 81ºF (27ºC).
Disposal
Waste disposal must be in accordance with existing federal, state and local environmental control laws. Incineration is the preferred method of disposal.
