Best of the Best - 10 out of 10. Very powerful stick. Very easy to apply and has a firm bond. Definitely recommend. It may be slightly more expensive than other brands, but does the job no question. Nice and wide too so you get good coverage. I ordered 15-meters, arrived 3 x 5-meter rolls. Good delivery. Have used on the bottom of our hot tub Review: Great tape and cheaper than the other brands - Used to waterproof tile backer board in a shower. If used with the large panel board washers and screws, this does sit quite proud of the surface, so does take a little bit of thinking when tiling ontop. However was easy to cut and sticks to anything and everything. It is not necessary to get the premade bottom corner pieces, however it would make life easier. It was unclear whether tanking membrane was required to stick the felt edges down, so I went belt and braces and liberally coated the tape with Everbuild Aquaseal Waterproof Tanking Membrane. ## Features - EXCELLENT FOR SEALING LEAKS: Introducing the Self Adhesive Waterproof Tanking Butyl Tape, a must have tool to help prevent leaks and water seeping through in your bathroom, shower or wet room.
