To strip or not to strip...?

[jambo000]

Hi all,

I'm currently renovating my bathroom and i've removed everything from the room leaving me with a concrete floor. I'm fitting a shower base and making a few changes to the plumbing , i'm also tiling the room from floor to ceiling. I've got durasheet boards for tiling in wet areas but the bathroom has still got the existing pasterbaord , i had originally planned to cover 2 walls in concrete sheeting (wet areas) over the original plasterboard however all the diagrams i see for fitting shower bases show the concrete sheeting against the studwork. My question is...do i strip off the existing plasterboard back to studwork and then fit my durasheet straight onto the studs...OR...do i cover the plasterboard i have with my concrete sheets. The other 2 walls (square room) are not wet areas and i intend tiling over the existing plasterboard.
Any advice is appreciated...
jim

well mate , its like this....you could cheat and just place duraboard over the plasterboard ....and it will look fabulous for a while ....then when moisture gets in ....the plaster will swell and have a party ...tiles will work loose .....and before you know it .....its open house .....everyone is invited ......so umm ....do yourself and your hip pocket a favor ..and take the plasterboard off first ....check the studs, and replace any showing wear....and go for it and umm .....if its not too much bother .....could you post us some pics?.....not everyone one is a rocket scientist here and I am sure someone will learn something for your experiance

I have had less than favorable results with BGC Durasheet. The sheets arent as stiff or as hard as Hardies sheets and they crack and disintergrate when in contact with water.

I've got the message as far as durasheet is concerned , i've replaced it with duraliner instead. Didn't realize about the movement between plasterboard and duraliner though , i think i'll strip - thanks for the advice - and will post pics when i can.
