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.

Composition
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 > 200F. 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.

Application
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 150F+ to -20F. Treat surface with
EternaPrime for installations from 40F to -20F.
