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

[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.

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:
