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.
Review: Seems good. Time will tell - I used this to tank my shower cubicle. I used backer boards to line the walls. And used the tape to seal the joins and cover the screws. It is easy to cut as required and sticks well once rolled down. It seems to provide a good watertight seal and I was able to tile over the boards and tape with no problem. Only time will tell if it fave a good seal but I am confident it will.
