Review: Be careful when applying - So strong adhesion, great to have but a pain to apply, once stuck virtually impossible to reposition! Great for the function but take great care with removing backing paper otherwise the adhesion gets you! A two person job if length is more than 30cm (or grow a third arm!) All in all a great product
Review: Good tanking tape - Used this on boards in my bathroom. Seems to work well and has helped with the tanking

### ⭐⭐⭐⭐⭐ Good tanking tape
*by M***H on 9 March 2025*

Used this on boards in my bathroom. Seems to work well and has helped with the tanking

### ⭐⭐⭐⭐ Instructions on the package
*by M***M on 21 August 2025*

Good, but when you remove the first side piece of paper the tape will start to sag. Remove a small piece at a time. It is more difficult with long pieces of tape . I would think the more you use it the better you will get. A few basic instructions on the tape packet would be helpful.
