Waterproofing shower/ bath walls

[***Tom11***]

1500 x 700 low profile tray on solid floor. Newly plastered walls.
What system do you recommend to waterproof the walls ?
Any recommendations for the Topps matting or a roll on type ?
Will the walls need priming 1st ?

Any help is appreciated.

What sub surface is the plaster on ....not plasterboard I hope it will swell and force off the tiles. The best way is proper non absorbent wall board which can be tiled directly. Then you need to sort out the interface between the shower tray or bath properly. When carried out well it can remain good for years.
I have some holiday lets in Cornwall each done this way ...and remember these customers really bash the installs...no problems now after 10 years from the oldest one. Mind you no plastic baths ..pressed steel, no plastic shower trays either as they move around too much whatever you do.
