Tiling on to Chipboard (Bathroom )

[lad25]

Just after a bit of advice , I'm going to tile my bathroom floor which is chipboard and solid . Its about 2.5m2 so I was thinking about using hardibacker 6mm to cover . What adhesive would you suggest for sticking the board down with and what screws also what grout and adhesive would you suggest for the tiles ? Or do you suggest a different method altogether .......

Thanks
in advance ..... :huh2:

Sorry, I should have asked this one first time round ... is it a typical practice (noting the small space that I am working with) to use the ply in plank form, covering the floor with a number of pieces (staggering joints with the T&G underneath) or should I be trying the craziness of laying the PLY as a single sheet (I can't see that to be possible). When pieces of PLY butt up to each other, what should I be doing about those edges? The same as just suggested for the outer edges, I guess?

You can get ply in 2440x1220 sheets so should fit straight in with only minimum cutting.

But with the "whites" already fitted, I'll have to either cut the PLY around them or would it make more sense to lift them out, do the tiling and then put them back in? In asking, I realise that the finish would be better, if I did ... and if that's the case, I guess that my builders could have done me a favour and spoke to me about this before they plumbed everything in.

On Mapei's adhesive selector they say that, Ultramastic III, Keraflex maxi, Keraquick with latex plus, Granirapid, Elastorapid, S2 Ultraflex mono and S2 Ultraflex quick can all be used on chipboard. I have'nt used them on chip floors
