Hello, Im new to the forum, but have an issue.
I have just taken down all the tiles off my bathroom walls floor to ceiling 4 walls, both the inner walls have collapsed, the plaster and base have come off the breeze block, and is now bare breeze block.
The other two walls have come away to a firm "backing" and has taken the majority of pink off the wall.

For the breeze block I am thinking of dry-walling it with plasterboard and then tile to the plasterboard. The outer walls was wondering if its ok to tile direct to the backing it seems very solid with good key?!

Im tiling with 600x300 travertine tiles 10mm thick approx. and mapei gypsum primer, mapei keraquick adhesive and grout.

Is there a problem with my approach or does it sound ok! your input is much appreciated.

Thanks

you would find it easier to chase outer walls back to brick and plasterboard all walls gives a smoother truer structure to tile onto and will erradicate the issue of weight per sq metre. plasterboard walls will take 32kg psm were as plastered walls will only take 26kg psm. with tiles of this size you need the walls to be ultra flat and smooth for the best results you do not want to be building out with adhesive to level the tiles.
hope this helps oh and

Same as, take the rest of the old plaster off and dry line the whole lot, then you know it's going to flat and plumb

Sharp Russ, nothing gets past you!

It is Grumpy, missed that one

I know it is, was just trying to be diplomatic!

Okay -so how heavy is a sq metre of 600x300x10mm travertine tiles with adhesive and grout.( and should this be a 600x400mmtile?)

John.

Look below, made a right hash of that

Tiles and Adhesive Weight Per Square Metre - THE TILE SOURCE

hmmmm,does this mean render or backer board?,or maybe take a "risk" on plasterboard,any thoughts.
what would u do,honest answers pls

to the forums m8
ged

Just as a matter of intrest to myself by "render"do we mean sand and cement or an undercoat of plaster such as browning with or without a skim coat?

Sand and cement m8

yes sorry grumpy was typing and playing poker at the same time didnt notice that i had hit wrong key.

dry line all way roun for me too

Yep. Dry line with plasterboard for me too

(then tanking kit if required) and then tile.

Only reason I added tanking bit is because we had a mish-mash of surfaces to tile
1) Dryline
2) Plaster
3) Ply
4) Stud

Tanked everything and then tiled over the lot
