Key item features

  • RoofSeal is the best solution for leak repair or corrosion protection in tough environments and conditions, including land-fill and pond liners and RV Roofs. RoofSeal is the product used in the EternaSeam kit.
  • The specialized backing has proven to be UV stable, even after 16 years in full sunlight.
  • The patented Eternabond adhesive has an integrated primer which enables RoofSeal to BOND with the surface it is installed on. It can be applied without primer to most clean surfaces. This is NOT true for butyl adhesive tapes. They all need to have primer applied.
  • Perfect for re-seaming all roofs, regardless of the material, RoofSeal makes a permanent water-tight seal (except silicones). Also great for tank repairs.
  • Rubber, fiberglass, aluminum, modified, shingle, PVC, steel, hot-tar, etc.
  • Elongation factor greater than 700% guarantees RoofSeal will flex, expand and contract in all conditions, even on liners!
  • Can be installed to -20 degrees F (with EternaPrime).
  • Sag rating of over 250 degrees F.

Tenacious Stuff

It is tenacious stuff. It sticks like crazy. It is easy to manage with the backing supplied but it is necessary to align it properly before applying it because it sticks like crazy. However, it is capable of being creased or folded to restore alignment if alignment is not perfect. But it will stick to itself like any other tape and cannot be easily removed after application without causing some damage.

The answer to leaks on RV

My brother tried flex seal and multiple other products, leaks continued. I cleaned up his "mess" (removed flex seal, etc...) applied tape as directed, problem solved. Amazing product

When you install this on a clean surface on your RV roof it is permanent. It is great around the skylights or along the edges. You'd better get it right the first time because there's no lifting it back up. I've been using this EternaBond tape for years and I love it.
