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)

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.

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.

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

Did the job but the thickness of the tape made levelling of the tiles very difficult, especially in the corners.

Very good tape, easy to apply and bonded very well to the boards.

Saved me so much time when waterproofing my wetroom. Rather than using tanking slurry and membrane tape, which would have been messy and time consuming, I was able to tape up within 1 hour. I did one line using traditional methods and quickly gave up!! Done and dusted no mess at all. Customer service was great had an issue with one of the tape as the backing paper was too sticky and would not tear off resulting in me wasting alot of tape. I reached out and a new 5m free of charge was posted out on a next day delivery. Best practice, I used OB1 around all the edges of the wetroom. Once dry after 24 hours I used the tanking tape. After tiling I used silicone. Overall ID BE shocked if any water passed through!

Great stuff, we’re now using it on every installation

Superb adhesion from tape. Bought to replace Mapei waterproof tape which would not adhere to Qboards installed despite, liberal use of Mapei tanking liquid. Removed all useless mapei tape, and tanked over Nassiboard tape. Without question, would advise purchase this tape, and buy any tanking liquid
