Afternoon

I know this is a similar thread to one already started however slightly different so warrants a new thread?!
I have a 'Sun Room' floor to tile in a 1st floor extension.
The floor is softwood floorboards with no obvious deflection & the tiles are 900mm plank wood effect porcelains.
I recommended 6mm Hardibacker stuck down with rapid flexi with scrim tape joints & screwed when dry.
The customer has bought 6mm Orbry board......?
I questioned whether this would be rigid/stable enough as an overboarding method especially with such long narrow tiles.

What are your opinions/recommendations?

Thanks in advance

Provided the deflection is as you say, then yes, they'll be fine to use. Fit as per the HB with https://www.tilersforums.com/forums/tile-adhesive/ and screws.

Christ, thats a turn up..so your supposed to trowel https://www.tilersforums.com/forums/tile-adhesive/, bed hardibacker and leave to dry before screwing it down..well that's a new one on me, just checked website and can't find that snippet of information..like a link to that :)

Well the way I'd look at, if there was no instruction in the installation notes is this, if you're screwing down 6mm Hardie into wet https://www.tilersforums.com/forums/tile-adhesive/ it can deform.
We know the idea is for the https://www.tilersforums.com/forums/tile-adhesive/ to give u a flat surface for the Hardie,
So if u don't wait for it to dry and screw it down, u stand the chance of not getting a flat surface.
After all, that's one of the objectives of using it, is t it?

Just the way I do it, to me it squashes down the addy and fills the voids properly , if it deforms the boards that bad your floor is buggered and should be straightened with a bit of slc .
I don't expect Many to agree with me on here ,I've stopped more threads than Mike Tyson stopped fighters, although I did get told to do it like that on here years ago, but folk change there mind like the wind on here and tend to forget, I love it on here :tearsofjoy:

The idea of the addy is to fill voids under the floor, not straighten it, folk make things up as they go along on here , what do you do, dot and dab the bloody thinks, we are making the floor a surface to tile onto not straighten like drylining, if it needs straightening, you slc it, **** , though, I'm a plasterer, I should be drylining the floor, I'd be good at that

What are u talking about! That's nonsense!
U really do get ur knickers in a twist on here lately Craig!
Not the person I remember!
If u have a straight board and u fill the voids with https://www.tilersforums.com/forums/tile-adhesive/ you're straightening the floor!
By the very words 'FILL THE VOIDS!' You're straightening the floor!
A void is a dip in the floor is it not!
So if u fill that void, u've straightened it!
I never once mentioned LEVEL did I!
So by that rationale, u lay your Hardie in wet SLC do u!
And if u read my post more carefully, it says 'the way I LOOK AT IT'
It wasn't a definitive answer!

I would use either, both will achieve the same.
Hardie should be screwed when https://www.tilersforums.com/forums/tile-adhesive/ is wet. The screws hold the board down, the https://www.tilersforums.com/forums/tile-adhesive/ fills the voids, they both work together and it should be done wet to squeeze the https://www.tilersforums.com/forums/tile-adhesive/ down tight, otherwise if you were Hardie-ing over uneven boards, you'd have to slc before laying hardie? and you wouldn't screw through slc would you? Also, doing it dry stand the risk of de-laminating the https://www.tilersforums.com/forums/tile-adhesive/ / hardie bond, surely?

Well as the customer has bought 6mm Orbry I'll probably use that.
Does that need screwing when wet?
