First time tiling floor with Schluter Ditra matting

[vinnykaka]

Hi there everyone,
I have been using this forum as a guest to get info and all contributors have helped a great deal so i wanted to become a member and join the community!!!
I have done several tiling jobs on walls only but now i have been asked to do 2 complete bathrooms with ceramic on the wall and porcelain on the floor.
The client has bought ll the materials and he showed me a roll of orange Ditra matting and i was thinking man, i dont know how to use this stuff. I have watched a video on youtube but just wanted any expert advice/tips that will help me.
Many thanks in advance and i am also dying to show you some before & after pics of the jobs that i have done previously.
Thanks peeps.
Vinny

Ditra is easy to install.. use adhesive suitable for the substrate...

Again what is the substrate..?

And most of all... :welcome:

Hi Dave,

I am removing the old floorboards and replacing with 18mm wpb exterior plywood as that is what's supplied by client.

Also, what size of trowel do i use for the tile & Ditra to plywood?

Thanks for the speedy reply..

No probs..

18mm... you will need to make sure plenty nogins are added between the joists.. a simple overlay with no support is insufficient ..

A 4mm trowel is needed for the application of the matting and mix the adhesive wetter than normal for a nice full coverage.

do i use the same size nogins as the joists?

what size trowel shall i use for the tile addy..10mm?

If you can add the same size noggins, this will stop joist twisting as well.. and 10mm notch is fine..

And use Dural instead, available from www.wetdecs.co.uk.
