- Ready-to-Use Product Features
- Outstanding Features
- Extremely chemical resistant to oils, fats, acids and other con‐ taminants
- Penetrates into gaps and cracks then it swells as it sets to plug leaks
- Saturates easily into reinforcing fabrics and coats evenly over irregular surfaces
- Remains flexible at low tempera‐ tures; will not flow at high tem‐ peratures
- Effective protection for all cli‐ matic extremes over long peri‐ ods of time
- Exhibits good adhesion to as‐ phalt or coal tar, BUR, Modified, zinc, copper, steel, lead, alumi‐ num, tin, E.P.D.M., concrete and mineral composites
- Provides a high quality mem‐ brane that will resist impact, impingement, abrasion and much physical damage
- Restores strength to damaged or weakened substrates and mate‐ rials
- May be combined with K‐ Catalyst to reinforce and add strength to surfaces
Applications & Uses

- Applications
Surfaces must be dry, free of dirt, loose debris, grease, oil, or any substance that could interfere with adhesion. Refer to POLAPRIME data sheet for information regard‐ ing selection of appropriate primer if necessary. Application over seams in metal roofs is 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 appli‐ cation at sufficient thickness to remove all voids, fishmouths and dry spots. Bolt heads on metal roofs should be daubed with suffi‐ cient ROOFDX SUPER that they are encapsulated to the point of run‐ down. As soon as the ROOFDX SUPER has dried, it should be coated with a compatible topcoat. Application over built‐up or modi‐ fied asphalt 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. If the surface is slicktop, capsheet, or re‐saturated, this should be vacuumed, blown or pressure washed until clean and, if excessively porous, primed with POLAPRIME 2. Application of ROOFDX SUPER may proceed by embedding 40” ROOFAB into a fresh coat of ROOFDX SUPER ap‐ plied 1½ gallons per 100 sq ft (66 sq. ft. per gallon); the fabric should be smoothed out without stretch‐ ing so that it conforms to the sur‐ face without voids, tents or dry spots. Begin at the lowest point of the roof and each roll satu‐ rated 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 over‐ lap that saturation occurs completely without fishmouths or dry spots. Continue application with laps facing downhill to shed water if work is interrupted by pre‐ cipitation. Sudden precipitation will not wash ROOFDX SUPER off when wet or newly applied, but will pro‐ duce a mottled, dull appearance that is not detrimental to overall performance. ROOFDX SUPER may be used as an adhesive at loose edges and will form all flashings and joints with the ROOFAB. Black surfaces, by their nature, will absorb heat; this heat buildup causes expansion, followed by con‐ traction as the surface cools. This constant expansion and contrac‐ tion causes fatigue of the substrate including the roof beams, fasten‐ ers, and other building compo‐ nents. To reduce the intensity of this cyclic fatigue and to reduce demand for air conditioning by lowering temperatures, a coat of a compatible solar‐reflective roof coating is recommended. If solar panels or other overburden is to be installed, use appropriate separa‐ tion layer.
