tesa Ultra Power Under Water Super Duct Tape - Extra Strong Repair Tape for Repairs on Wet and Dry Surfaces - Highly Weather Resistant - 1.5 m x 50 mm

Fantastic product, sticks well, waterproof and long lasting. Used at home on several items.

Used for cracks in Acrylic bath. Prepped and dried before using tape. So far after nearly two weeks of showerings soaps and cleaning still stuck to the bath and keeping it water tight.

Ideal

Good adhesion also easy to tear but like most sticky tapes glass has to extremely dry or it won’t adhere.

Does not work. We had a small leak in our guttering. No great pressure at all, but the tape won't stick to the guttering to create a seal, even when we applied several layers! Certainly would be no use under water. Should never have believed their marketing hype, and saved my money.

Superb,works well

Works as long as only part underwayer

Sticks to absolutely everything

超強力、皮膚につくとやばい

Solide et transparent pour différents usages

Macht genau was es soll, entspricht genau der Beschreibung.

This is very thick tape, I think that is what makes it 'ultra Power'. I was not impressed by its adhesiveness/glue, it wouldn't stick well to rubber materials. The tape itself is very thick which would make it more durable I guess, however this makes it less flexible and wrapping it around something didn't turn out nice. If you are looking for thick tape that's expected to have a lot of grinding wear, then this would be a good choice. Do take into account the downsides I described earlier.

Perfetto, ottimo nastro
