Is Plywood ok for a partition wall?

[doug boardley]

give and take advice in a friendly way guys please:8:

offended, me, never!

your studding looks perfect, chamfered edge plasterboard, taped and jointed with plasterboard adhesive, providing your tiles and adhesive are less than 32kg.(tanking wet areas of course!)

otherwise,

Wedi board, marmox, knauf, no more ply, hardibacker, or wicks waterproof board!

but remember, even though the boards are more stable you still need to sort the joins in the boards out!

good luck..

Thanks for the compliment, I try to learn what I can and do my best.

What do you mean by sort the joins in the boards out?

Using plasterboard would save quite a lot of money, what is involved with tanking?

And I presume it would only need tanking in the shower and around the bath area?

PS. The Wickes board is Knauf Aquapanel.

you still need to tape and join backerboards, the boards are waterproof but the joins are a weakspot!, so you will need to put skrim tape over the joins and screed with a flexable adhesive!

tanking in you situ is easy, paint on so to speak!

2 coats, one coat left to right , second coat top to bottom!

I do wet rooms quite often so:

this is a wedi board (tilebacker) room and i am taping the joins with wedi tape and tanking paint!

and a bit later, but you see what i mean about the joins in the boards!

finished job:

According to the large commercial instructions, when using the Knauf Aquapanel joint adhesive there's no mention of using scrim tape, these instructions also imply that it stronger, as you can use 600mm centres on the battens, where as the domestic/small commercial instructions state using 400mm centres and the scrim tape, with flexible adhesive.

This information is on the Knauf website Knauf Drywall - Aquapanel - Drywall for Wet Areas

Now the only problem I have is deciding which way to go as some posters say use plasterboard and tank, and others say use a backer board.

Edit: Very nice looking job Dagger, and I spy a laser level, wonderful inventions them.

Ronski, it depends on the weight of your tiles, as to what substrate to use, cement boards will bear more load than plasterboard

 

[dagger]

if your tiles are less than 32kg including adhesive you can use both, if more use tilebacker.

that said i have NEVER known anyone to not reccommend sealing the joins in any board aquapanel or other!

grout is water replellant, so water goes into the grout, and dries out through the grout (hence the change in colour), if you are not suitabliy "tanked" the water in the grout can "ebb" into the wall, if where it ebbs is on a join you have a failure!

just my opinion, but i am pretty sure of myself..

im with dagger on this one :8:
