EternaBond RoofSeal Mobile Home & RV Repair Tape 12" x 10' White — UV-Stable, MicroSealant

This 12-inch wide by 10-foot long section is precision-cut from new master rolls to give you the same professional-grade RoofSeal used by roofing specialists. The product combines a durable, UV-resistant backing with EternaBond's MicroSealant that includes an integrated primer to adhere to diverse surfaces quickly and reliably. It’s offered in white to match many roof finishes and to reflect sunlight for cooler surfaces.

How does this tape bond to different roof materials?

The tape uses a MicroSealant layer with a built-in primer that promotes adhesion across many substrates without a separate primer step. It forms an immediate tack and then cures to a permanent, waterproof seal as it conforms to surface irregularities.

• Works on EPDM, TPO, Hypalon and most PVC membranes
• Adheres to metal roofs, including painted, copper and Kynar-coated surfaces
• Suitable for tile, wood, concrete, pond liners and landfill liners
• Designed to re-seam and repair tears, punctures, and open seams

Will the tape hold up outdoors under sunlight?

The backing material is formulated for long-term UV stability; EternaBond reports field performance lasting decades in full sun exposure. That UV resistance helps prevent premature breakdown, discoloration and loss of adhesion when used on exposed roofs.

• UV-stable backing tested over long-term outdoor exposure
• White color helps reflect sunlight and reduce heat absorption
• Resists weathering and remains flexible to accommodate thermal movement

How easy is it to apply and what prep is required?

Application is straightforward and intended for both pros and DIYers: clean, dry the area, peel the release liner, position the tape and press firmly. For best long-term results, remove dirt, oils, loose coatings and heavy oxidation before applying.

• Cut-to-length 10-foot section from a master roll for ease of handling
• No separate primer usually required due to built-in primer in the MicroSealant
• Use a roller or firm hand pressure to ensure full contact and watertight adhesion

What typical problems can this product fix?

RoofSeal tape is intended to repair common leaks and breaches that allow water intrusion: seam separations, punctures, small tears and flashing gaps. It also works for preventative patching or creating continuous re-seams on worn roofing details.

• Patch punctures and tears on RV and mobile home roofs
• Seal open seams, splits and flashing edges
• Provide continuous waterproof re-seams on a variety of roofing systems
