For use on virtually all roofs, RoofSeal/OneStep Tape incorporates Eternabond’s advance MicroSealant Technology and features a UV stable backing.
RoofSeal/OneStep creates a waterproof, moisture and air tight barrier with no additional sealing required. RoofSeal/OneStep remains flexible to temperatures as low as -70°F making it virtually impossible to thermally shock the roof causing a leak.
RoofSeal/OneStep permanently bonds to materials such as EPDM, TPO, most PVC, CSPE/Hypalon, CPE, SBS, APP modifies, asphalt BURs, coal tar BURs, all metal roofs, tiles, shingle, aluminum, Galvanized steel, gypsum board, wood, polyethylene, propylene, polystytrene, fiberglass, brick, concrete, masonry, OSB, etc.
Eternabond RoofSeal/OneStep Tape is used to seal roof joints (seams) and tears, flashings, copings, skylights, gutters, etc. Perfect for repairing and restoring roofs on mobil homes and RVs. Very flexible, RoofSeal/OneStep seals to itself so it can be cut and folded around an object, as if wrapping a present.
