Adhering James Hardie Tile Underlay to timber floor
Hello @Obadiah
Welcome to the Bunnings Workshop community. It's fabulous to have you join us, and thank you for sharing your question about tile underlay.
I suggest having a quick read of this discussion - Tile underlay adhesive onto plywood floor by @BryceBrad. The recommended adhesive mentioned in the discussion is Stud Adhesive. I recommend using Paslode 25 x 2.5mm 500g Underlay Cement Nails 410 Pack to nail the sheet down onto your floor.
It sounds like a fantastic tiling project, any photo updates you can provide would be highly appreciated.
If you need further assistance, please let us know.
Eric
