UK Tiling onto hardwall with membrane

[josephs]

Hi,

I'm currently prepping a shower for tiling. One wall has been built out for the shower pipework, which I'm covering in 12mm wedi board. The other is an internal brick wall, which is currently scratch coated with hardwall.

Having read around here it seems tiling directly onto hardwall is a no no, but my plan was to apply a waterproof membrane over this with tile adhesive before tiling (something like kerdi 200). Would this be enough to stabilise the wall, or is it still necessary to skim the hardwall first?

I'm really not keen on boarding the wall as it's going to eat into the space we've got and having baton and boarded some other walls, I don't know if I get face getting the drill through more of our crazy bricks.

Any advice would be hugely appreciated.

Schluter Kerdi 200 like products are perfect for the application as long the wall is perfectly sound, make sure you apply the corner band up the wall/corner. Send us some pictures. Good luck!
