• What adhesive should I use for my tiles?

We recommend you use a cement-based flexible tile adhesive (Class C2 / S1 according to EN 12004 - 12004).  If you need better waterproofing than just the tiles, use a waterproof adhesive provided it is cement based.

• If lining out a shower area in my house, do I need a polythene sheet to the back of the board?

No, for domestic application this is not needed.  A polythene sheet is more usually applied if it is to be a walk in shower or wet room (ie no shower tray), or for heavy duty or high use areas, such as changing rooms and swimming pool areas.
