Floorboards

[Gareth1]

Hi,

I've been reading about preparing a tongue and groove floor for tiling but I'm still confused about what to do. I want to tile over floorboards in my bathroom preferably with travertine tiles. Can I just overboard with 6mm or 12mm Hardibacker?

Thanks,
Gareth

You need to make sure that there is no bounce in the floor before you do anything.

Plus,how much room do you have to play with height wise ?

The floor feels sturdy to me but I'm not experienced. I tried filling a glass of water to the brim, placing it on the floor, and walking around it. None spilt and there was very little to no movement of the surface. The water moves a little if I jump on the floor but not by much.

With regards to height, I can raise the floor if needed and I'd rather overdo the job than do it twice. The only slight problem is the step up entering the room - the WC soil pipe etc. will be OK. I'd like to minimise the step if possible though.

If you feel the floor is sound I'd go for the 6mm hardie glued and screwed...

I'll use 6mm hardie then.

To stick the boards down, would using a 6mm square notched trowel and a rapid setting flexi adhesive be right (putting screws in while the adhesive is wet)? I have some BAL rapidset flexible left over. Should I prime the floorboards with SBR?

Thanks,
Gareth
