EternaBond RoofSeal Microsealant Repair Tape 6" x 10' White — 35 mil UV-Stable Waterproof Seam Tape

EternaBond RoofSeal White is a 6" x 10' microsealant repair tape that creates a durable, waterproof and airtight seam over roof materials in a single application.

This one-step RoofSeal tape combines a flexible, weather-resistant backing with a pressure-activated microsealant adhesive to stop leaks, reseal seams, and patch tears on many roof surfaces. Offered in a 6-inch width and a 10-foot length cut from new master rolls, this white tape delivers a total thickness of 35 mils for long-lasting protection against moisture and UV exposure. It’s formulated to adhere to a wide range of substrates so you can repair flashing, seams, penetrations, and damaged membrane sections quickly without primers or heat in most cases.

What surfaces can this microsealant tape bond to effectively?

EternaBond RoofSeal adheres to a broad variety of roofing substrates used by professionals and DIYers. It bonds to rubber membranes, most PVC and TPO materials, metal panels, tile edges, wood, concrete and specialized liners. The tape’s chemistry and thickness are optimized to maintain adhesion under temperature cycles and exposure.

• Suitable for EPDM, TPO, hypalon and most PVC membranes
• Strong adhesion to metals including copper and Kynar-coated panels
• Works on tile, wood and concrete surfaces when clean and dry
• Compatible with pond liners and landfill liners for containment repairs

How long does a repair last and how does the tape resist weathering?

The 35 mil total thickness and UV-stable white outer layer help the tape maintain a watertight seal and resist solar degradation over time. When applied according to instructions on a properly prepared surface, the tape creates a permanent, flexible seal that moves with substrate expansion and contraction. Longevity depends on environmental conditions and proper surface prep.

• UV-stable top coat reduces color and property breakdown from sunlight
• Flexible construction tolerates thermal cycling and wind uplift
• Designed for permanent, water-tight seam repairs when applied correctly
• Best results on clean, dry, and grease-free surfaces

How do you apply EternaBond RoofSeal for a reliable repair?

Application is straightforward: clean the area, scuff smooth glossy surfaces if needed, position the tape, and press firmly with a roller. The microsealant activates under pressure to form an immediate bond; overlaps and edge rolling improve performance. No solvent primers or heat welding are normally required except in specific low-temperature or oily-surface situations.

• Prepare surface: remove dirt, loose material, oils and moisture
• Cut tape to needed length and align over the seam or tear
• Apply pressure and finish with a roller to work out air and ensure adhesion
• Overlap existing seams by recommended width for full waterproofing

Can this product be used for professional re-seaming or quick emergency patches?

Yes. RoofSeal is suitable for both permanent re-seaming jobs and fast emergency patching. Professionals favor it for re-seaming entire runs or patching details; homeowners and maintenance crews use it for immediate leak control until a larger repair can be scheduled. Its simplicity and reliability make it a go-to for many roofing tasks.

• Trusted by roof repair specialists across multiple roofing types
• Ideal for flashing repairs, seam reinforcement, and puncture patches
• Quick-to-apply for emergency stops; durable enough for long-term repairs
• Available in white for heat reflection and visual match on light roofs
