tileing shower

[mik h]

Hi there
I have been doing my sons bathroom in old victorian house. Wall so bad that I have had to build new wall with exterior grade plywood on 3x2 battens.
Part of this will be in a new shower cubicle which i have nearly plumbed in.
I am now worried about the use of exterior grade ply in the shower area in particlar.
The last thing I want to do is remove the ply, which is 18mm .
Could I use the ply with a treatment prior to tiling or could I place a moisture resitant board on top of the ply in this area.
Where I have the ply behind toilet etc ( not wet as such , could you please advise on a suitable pre- tre-treatment for the wall. this only to dado height ( 10000MM)

any help gatefully received
Mik H

thanks for that Just one thing whats Hardie backer.? Is it the Plasterboard thats moisture resistant?

 

[paul flight]

hardie is a cement base type of board (topps tiles.) wedi/marmorex is a light weight board (tilefix direct)search!

 

[The Legend; Phil Hobson RIP]

Sorry, as Paul says Hardie is a cement board, Wedi, Marmox etc. are light weight backer boards, much better in wet areas than plasterboard.

either hardie/marmox/wedi are all excellent products and far superior to tile onto that plywood
