Ditra

[Sean SML Tiling]

Customer asked today could I lay ditra onto floor boards instead of using hbb. I dont feel comfortable doing this what do you guys think is the best approach

 

[DHTiling]

Depends on how solid the boards are..?

 

[Sean SML Tiling]

They are pretty solid hardly any movement. Is it suitable for wood floor?

 

[bugs183]

What kind of floor is it? If the floor is solid and stable then It's fine for plywood, chipboard though is always a worry.

 

[Sean SML Tiling]

It is chipboard that's y im a little concerned. Hbb is so much cheaper bit dont understand y they want ditra

 

[bugs183]

I'd be tempted to glue and screw a cement board like Marmox, lovely to use.

I would prefare to use Hardie board glued and screwed, Ditra is for lateral movement and will do nothing for deflection. Imo.

 

[Sean SML Tiling]

Ive suggested other products but they seem to want ditra.

 

[The Legend; Phil Hobson RIP]

Sorry Bugs, post overlap.

 

[Sean SML Tiling]

Would a 2 part flexible be more appropriate

 

[DHTiling]

ahh chipboard... no use hardibacker..

 

[bugs183]

Nah SM you need to get the chipboard out of the equation by isolating it, two part won't help.

 

[Sean SML Tiling]

Cheers guys. Looks like hbb or they cam get someone else to do it.

 

[bugs183]

At least they've done some homework and asked for Ditra!
We've been using it nearly 20 years and it's only recently that people are starting to know about it, but since then other systems like backer boards have appeared and again people are slow to catch on.
Is this a floating floor??

 

[Sean SML Tiling]

No its not floating
