EternaBond Roof Seal Tape – White, 2 Inch × 50 Ft

EternaBond Roof Seal Tape in white, 2 inch × 50ft, uses the same industry-trusted MicroSealant technology as the 4-inch roll in the narrower width that is ideal for smaller seams, tighter joints and precision work.

When should I use the 2-inch width rather than the 4-inch?

Use 2-inch tape when you need precision — sealing along a narrow edge, around a small penetration, or in a location where a 4-inch tape would overhang onto surfaces it shouldn't. For full roof seam re-sealing and Heki vent surrounds, the 4-inch roll is the better choice. Many caravanners keep both widths: the 4-inch for major sealing work and the 2-inch for detail and touch-up jobs.

Can I apply EternaBond directly over my existing sealant?

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

Do I need a primer?

On most caravan surfaces — aluminium, fibreglass, EPDM, and painted surfaces — no primer is required. For typical caravan sealing jobs, 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 expected. 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 adheres 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 even when the surface is slightly wet.

Will 50 feet be enough for my job?

At 15.24 metres per roll, the 2-inch tape is primarily suited to detail sealing work rather than full roof re-sealing. For major jobs involving full roof seam coverage, the 4-inch roll provides much better coverage per metre of seam. Contact us if you're unsure which size or how many rolls your job requires.

Can EternaBond be removed if needed?

EternaBond is designed as a permanent application and should be treated as such. While removal with heat and effort is possible, it should not be considered a temporary solution.
