Can anyone help. I have a hardboard wall and have twice put ceramic tiles (big ones that match the rest of the bathroom) on to it. Each time they have slid off. Should I prepare the hardboard wall in some way. Is there a special glue.
Not tiling the wall is not an option at the moment.

First you need to brace the wall, hardboard is too flexible. Then coat with PVA 1:3 and allow to dry before tiling.
Scrub the HB with the roughest sandpaper you can aquire. In reality though, HB is not an ideal surface to try and tile to.
OK, do you *really* mean hardboard? If so, that's really not an acceptable substrate - far too flexible for a start. Is this a stud partition wall, or what? Let's have some more details of the scenario and I'm sure you'll get some good advice.

All large tiles will creep down the wall under their own weight, roughened wall or not. Best to batten the wall and tile upwards.
Does he really mean hardboard I wonder ..

Don't tile over hardboard, it doesn't work, people put hardboard up to avoid having a wall plastered or dry lined, as you have already found out, it's false economy given that you'll have to re-tile it every twelve months instead of just using plasterboard once and then it's finished.
