EternaBond Roof Seal Tape – White, 6 Inch × 50 Ft

EternaBond Roof Seal Tape in white, 6 inch × 50ft, is the permanent solution for jobs too wide for 4-inch tape: a large vent flange, a full roof seam overlap, a pop-top lid seal or a repair over a wide area of failed sealant.

When should I choose the 6-inch width over the 4-inch?

Choose the 6-inch when you need wider coverage in a single pass — large vent flanges, pop-top lid joints, wide roof seams, or repair work over a broad area of failed sealant. The extra width means 75mm of adhesion on each side of a centrally placed seam, versus 50mm with the 4-inch. For most standard vent surrounds and roof seams, the 4-inch is sufficient. When in doubt, wider is better for permanent repairs.

Can I apply EternaBond directly over my existing sealant?

Yes, in most cases. Remove any loose, crumbling, or flaking material and degrease thoroughly, then apply EternaBond directly over the existing sealant. You do not need to remove sound, well-adhered sealant underneath — EternaBond bonds over it.

Do I need a primer?

On most caravan surfaces — aluminium, fibreglass, EPDM, and painted surfaces — no primer is required. For typical caravan roof sealing, primer is not necessary.

How long does the bond last?

EternaBond is a permanent sealing solution used in commercial roofing applications where decades of performance are required. In caravan applications, properly applied EternaBond typically outlasts the vehicle.

Can I use this in the rain or on a wet roof?

EternaBond is one of the very few roof tapes that will adhere to a damp surface — making it genuinely useful for emergency field repairs. For optimal bond strength, a dry clean surface is always preferable, but the tape will seal in wet conditions when needed.

How many rolls do I need to re-seal a full caravan roof?

This depends on your van's size and the number of seams. A typical 6–7 metre caravan has two main longitudinal roof seams plus vent surrounds and end caps. For a full preventative re-seal of all seams using 6-inch tape, one to two rolls is usually sufficient for the main seams, with the 4-inch roll used for vent surrounds and detail work.

Can EternaBond be removed if needed?

EternaBond is designed as a permanent application and should be treated as such. Removal with heat and considerable effort is possible but it is not a temporary product.

Is the 6-inch roll suitable for fibreglass roofs?

Yes. EternaBond bonds directly to fibreglass without primer, making it well-suited to the fibreglass roofs common on Australian and New Zealand caravans and motorhomes.
