Hi All,
I'm renovating my bathroom and tiling the bath / shower area in 12mm 30.5cm x 30.5cm marble tiles. The end wall will be fully tiled. Another two walls will be partially tiled (from the bath to a door on one side and a window on the other)
I've removed the old tiles which came off easily. The walls are plastered with a pink skim coat and then a thick (2 to 3 cm) layer grey of backing which I think is plaster (not sure). Two internal walls are lightweight concrete blocks and I believe the external wall will be concrete block too.
Here's my problem - I've read that a skimmed plaster wall can only support 20 kg/m2. To cover a square metre I'd need about 10 tiles which would weigh about 25 Kg. I think that, with adhesive and grout, It could be over 30Kg/m2 easily.
Some kind of waterproof tile backer seems to be a good solution. I've never used it before. Can someone recommend a product / system to me?
Do I remove the old plaster and fix the backer boards to the block wall behind and can I pack out the backer board somehow so the tiles are flush with the areas of wall which I'm not tiling?
Many thanks
Gareth
