floor tiles on wood floor boards

The standard way is to use ceramic tile underlay nailed to the floorboards with ring shanked nails. James Hardie have ceramic tile underlay, called exactly that (6mm fibre cement sheeting) with the nailing centres marked I think 150mm centres with 100mm centres around the edges. Then use a flexible adhesive such as Davco Ultraflex.

I think you can also get a special adhesive for direct sticking to floorboards but feels less solid to me underfoot.

Arms, James Hardie actually say the CTU is pre primed for this reason:

"Pre sealed sheets increases cement based tile adhesive working time by 50%"

but I usually also prime to seal the dust and give a better bond

Hi all, looking for some advice. Our kitchen has ceramic tiles laid over floorboards, I have done a test dig and found 20mm of concrete sitting on orange plastic sheeting. I was hoping that the 70's reno would have used masonite, but whatever!

Any ideas on getting it up without trashing the floorboards............thinking SDS hammer drill with 40mm chisel bit (ozito 1500w)

Theres a fair chance that the sand/ cement bedding will have chicken wire bedded into it for strength, so it's not going to be easy. Maybe you can just crack the bedding enough to get under it, and lever it up.
