1880 house with lime render. - Tile Advice

[sifly]

Hi, I am replacing a bathroom and after removing the old tiles have found old lime /horsehair render on brick. This seems pretty solid and wondered if I can tile over with 250 mm x8mm tiles after priming /stabilizing wall?
Or do I rip it off and render with sand/cement?... There will be a shower above the bath.
Cheers Si.

Mechanically fix a waterproof board through the plaster to the brick!

That's a possibility thanks, can I get a 6mm board?

Or rip it off and dry line...

Yes...

a 6mm board for tiling onto a wall????

 

[sifly]

I see the 6mm boards are mainly listed as for floors, would it be OK if screwed directly onto the render, or should I go 12? I don't have space for wood battens.
I'll make a decision later after I remove the tiles above the bath and see how well they are fixed.
Cheers Si.
Ps. Just hope the neighbours don't mind the hammer drill!

10mm Marmox with spankers would be my choice [emoji106]

Thanks spankers look good!
