What adhesive for ceramic tile underlay?

[clover-grove]

I have a back room / mud room type of set up. The flooring is structaflor yellow tongue. I had planned to lay Hardie ceramic tile underlay and tile over the top. The James Hardie website just says "appropriate adhesive". I'm a bit stuck. My understanding is that thinset would be appropriate, however, I'm still stuck on what thinset to use. I unfortunately haven't had any luck speaking to people in store.

I was also hoping to use screws rather than nails. Is this okay to do? There's only recommendations for nails in the installation guides.

Thanks in advance for any help

Welcome to the Bunnings Workshop community @clover-grove. It's wonderful to have you join us, and many thanks for your question about installing ceramic tile underlay.

The installation instructions call for a stud adhesive to glue the underlay to the timber, and I'd recommend Gyprock CSR 5.5kg Acrylic Stud Adhesive.

Unfortunately, I've enquired extensively about the copious amount of nails required for the installation and have been told that it's the only option.

Please let me know if you have any questions.
