    Basic Use

    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 mobile 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.


    Eternabond RoofSeal/OneStep utilizes EternaBond’s advanced MicroSealant™ Technology, a 100% solids formulation of synthetic resins, thermoplastics and non-curing rubber (non butyl) with a built in primer, bonded to a tough UV stable backing. Designed not to harden under even the most rigorous conditions. Sag temp > 200ºF. MicroSealant™ is protected (while in a roll) by a tough, easily removed siliconized polymer release liner, which prevents contamination prior to its use. All materials are prefabricated to provide uniform thickness.

    Surface Preparation
    Surface must be clean and dry; free of loose rust and scale, dust, talc, and dirt. Oil, grease, and other contaminants should be removed with a suitable solvent/cleaner. Use of EternaPrime reduces clean up. For older plastic roofs, score surface with sand cloth and wipe away dust.

    Install Eternabond RoofSeal/OneStep over the repair area, removing the plastic release liner gradually to prevent contamination of the adhesive prior to application. Rub or roll with pressure with hand or steel roller to activate bonding process. This material may be applied to clean dry surfaces from 150ºF+ to -20ºF. Treat surface with EternaPrime for installations from 40°F to -20°F.
