HardiBacker & Floor Level? - Tile Advice

[Dumbo]

the tiles on the concrete need adhesive say 3mm so that negates bringing that into the equation . So what the op needs to allow for is the difference in floor heights prior to tiling i.e. 6mm Hardie plus adhesive for Hardie which is not much ( especially for me as I tread mine in )

Thanks for the replies fellas, I appreciate the help. SLC is the way to go by the sounds of it. I'll pick up some decent S1 for the floorboard side.

I assume flexible grout will also need to be used on the floorboard tiled side, aswell as where it joins with the concrete?

Flexible grout is a must . Where the two floors meet you will need something more flexible than grout i.e. Colour matched silicone

Perfect, ok good job I asked that, I will be using a grey grout is that something you can pick up easily from a tile store, the silicon I mean, or is it just general no nonsense silicon type stuff?

Also I assume it's best to get the Hardiboards down and then sort the SLC up to the same level?

Most grout manufacturers do a matching colour silicone grout . Yes Hardie first the level up to it .

Thank you Jeremy. Wish I could be so succinct

I have good day taking the rip out a plumber so I thought I would give something back to the universe . Also first time this week I've looked from where I'm working to see you had worse weather than me .

It's been awful here. Festival weekend too. Good luck to the campers. Rather them than me!

Morning guys, the point I was trying to make, which I think may have been lost in the trail is that the total depth of product on the concrete side, from top of concrete to underside of tile may be 9mm once you take into account 6mm HBB and 3mm under tile adhesive upon that. If you were to try to tile 18m2 in one operation with adhesive on the concrete side, to me that is 9mm. If there were a problem and the adhesive rep cut a cross section through tile, adhesive, and concrete, they would indeed see ?mm.
We are on the same side no.
The laughable thing is that these same manufacturers imply no more than 3mm total depth to avoid "stress" but say on the bags "upto 20mm"
Sorry foe typos, its early.
