## Questions & Answers

**Q: Can you please explain how to use this with tile adhesive and backerboard? As it is not self ashesive, and the tile adhesive cannot pass through it li**
A: You are meant to paint over it with tanking paint after application. 
It is made deliberately porous so that is will soak up the rubberised tanking paint and stop the paint from ripping if joints or corners move. This is NOT a waterproof tape it is a part of a waterproofing system.

**Q: Is this self adhesive tape?**
A: Good Afternoon No this is stuck down with flexible tile adhesive

**Q: Can this be used with Nass boards tanking membrane?**
A: Yes no problem at all

**Q: can this be used with a tanking kit?**
A: Yes

*by Q***D on Reviewed in the United Kingdom on 20 July 2020*

I got this Waterproof Cloth Joining Tape for shower corner joints.Its difficult to put on, you need Waterproof Tanking Membrane to get it to stick.I wasn't happy and put better grade tape on instead.
