Board fixing advice please

[Dan1234]

Hi Everyone

Removed the plasterboard from a wall to re-board ready to tile. What I have found is that all the walls are battened with 50x25mm battens spaced every 400mm There is also insulation between.

Now will 12mm no more ply be okay to glue and fix onto these 25mm thick battens? Or should I fix through the battens into the concrete blocks with stainless steel screws?

Hi mate,

According to James Hardiebacker, no you cant. They should be minimum 2 inch (50mm) by 4 inch studs. So I'd be inclined to go into the block work.

Cheers
