Hi.
The walls in my ensuite are coming along well...
Just thinking about the floor now.
The original tiled floor was tiled over thin sheets of plywood. The ply was on top of T&G chipboard.

Is it ok to tile on plywood? I seem to be coming across articles or posts that suggest not.

I've come across Schluter Ditra Matting when buying my Addy for the walls.
Is this any good?
Which would be best?
I've not research either yet. So I don't know how they are installed. Do you have to lay them on https://www.tilersforums.com/forums/tile-adhesive/? Sorry, I'm at work and not got time to research just yet.
It's a chipboard floor. I think. Haha. It has no bounce. It's a very small area. About 1m x 2m. Perhaps 2.5m. can't quite remember.

Hardie Backer would be better on suspended timber floor, Ditra on concrete floors.

Ditra is used to protect tiles from lateral movement found in concrete floors and by itself offers very little protection from deflection in suspended timber floors.
If you want to use Ditra you would need to overboard your chipboard with a 18mm ply first.
Personally I always use 6mm Hardie and have never had a problem.

Use hardiebacker boards. 6mm notch trowel of https://www.tilersforums.com/forums/tile-adhesive/ then put boards ontop and screw with rust resistant screws (30mm) and scrim the joints of the boards and skim a coat of https://www.tilersforums.com/forums/tile-adhesive/ over it.

Ok Great. Thank you. What would I use as the scrim? Sorry, I'm a complete novis, who wants to do it right first time.

Whilst I'm here. Are the principles for floor tile the same as walls. What advise would you give. I forget the size of the tiles, perhaps 500x 500.

This is the tape/scrim. It must be alkaline resistant tape
