Nassboards Waterproof Tanking Tape - Aqua Elastic Self Adhesive Butyl Joining Permanent Strong Sealing Tape for Waterproofing Bathrooms, Shower Wet Rooms, Use Outdoors Indoors Preventing Leaks (20m)

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

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.

Easy to use and it sticks to anything

Bought to finish off a tile backer board install. I used Marmox backer boards but used this tape as it was about 2/3rds cheaper than the Marmox product. This sticks so well, easy to install, it has two pieces of peel offs which helps with corner installation. Highly recommended!

Really sticky - great stuff for a shower before tiling

Excellent quality honey.

Bought 20m which was supplied as four 5m rolls. Tape is easy to apply to single plane surfaces such as straight down or across a wall, where it excels, but very difficult to apply in corners such as a wet room. The tape has two strips of backing tape, you can peel one off before the other to push into a corner, however the tape stretches unevenly which then causes wrinkles. With 3 of the rolls the backing tape did not peel off correctly which then required picking at with a knife to lift the edge of the backing tape. The glue is very sticky, so once stuck near impossible to peel off and adjust. I used a roller to press the tape firmly down. Not the best experience, I would probably use tanking liquid and tape for corners if I was to do something similar.

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.
