re-tiling walls plasterboard advice replace or add a backing board ?

[Isidoro]

Hello

I am planning to refurbish the bathroom in my house. and I am not a professional


The walls tiles need to be removed and I am expecting the plasterboard will get ruined.

What is the best approuch

should I replace the old plasteboard with a cement board (like backing board aquapanel from wickes)

or could I just put the the new cement board on top of the original plasterboard using screw and adhesive ?

I suppose the second will be easier

thanks a lot

You could just Replace the plasterboard with new plasterboard and tank out wet area's.

Hello Ianflem

So from your experience for walls iwould it be easier to replace plasterboard ? instead of put a backing board on top ?

How is the current plasterboard fixed? Is it dot and dabbed to the block/brick or screwed to studs? Either way, it's a better job to replace rather than cover it over. Unless you are fitting heavy stone tiles, the cement board really isn't necessary, plasterboard is much cheaper also.

3 walls are internal so I am expecting are screwed but the external one could be dabbed
I suppose the dabbed one are difficult to remove.

the tiles are ceramic but they are a bit heavy: weight is 16 kg /m2 but I suppose it still possible to use normal plasterboard
however if I go for something like hardiebacker could it be pssible to replace the previous plasteboard for the walls ?

thanks a lot

Yes is the answer.
Seems you want to use Hardiebacker, so use Hardi

Isidoro,
Whether the boards are dot n dabbed or screwed to studs they can both be removed.
The weight you have advised will be fine on standard plasterboard.Cement boards can
be used if u wish.If it were me I would replace with new plasterboard and apply tanking
kit to wet area's (Shower etc).

If your going to replace use a waterproof board or tile backer board.

You ask the best approach. A pro who knows how to give you that bathroom you need with that wow! Factor.

I start my tiling tomorrow :sofahide: and for what its worth . . . . .

I took all the plasterboard off when I removed the old tiles. It had been dot and dabbed to the thermoblock walls and removing the dots/dabs took a long time but worth it. I rebuilt the surface with Tile Backer Boards and tile adhesive then tanked the whole lot.

Like most things - careful prep is the key.

Good luck. :juggle:

fairplay any pics mate?

How did you fix the backer boards? Dot n dabbed with tile adhesive?

 

[hedgie]

These any good?

 

[hedgie]

Not dot n dab - full cover with tile adhesive using 3mm square notched trowel. As the substrate was clean adhesion is good . . . . I hope - :yikes:

Walls must've been good.. I'm surprised you managed to get a flat wall that way, to be honest.

I'm looking to do the same shortly. Do I remove the tiles and adhesive fix 6mm Marmox board all over and use mechanical fixings also. Stud walls will be screwed to studs.

Is this OK for heavy travertine or do I need to remove all the plaster boards and re-board with 12mm marmox or Hardie backer ?
