16mtr, 600 by 600 porcelain kitchen floor on ply ? advice please !

[2020Tiling]

Hi ! iam after some advice on this one thanks. Ive got a Porcelain floor to tile in 2 weeks time, the tiles are 600 by 600 mat black slate effect with a hint of a silver speck when the light hits it. Anyway the floor is solid after been over boarded with 18mm ply on top of solid floor boards after nogins have been fitted etc, the floor has no deflection. ply has the correct expansion gap etc. The problem i have is thers an old chimney stack that has been replaced leaving a concrete slab where the cooker is and this sticks out around 12 inches from the plyths , so the ply has just been butted up to the concrete and is slightly higher than the ply floor? also the floor isnt 100% flat /level in places. just after your views on how the best way to prep this would be ? theres no ufh. I was thinking slc on the dips in the floor then ditra , but unsure how to tackle the old chimney slab ? what do you guys recon ?

I'd ditra first then level, this floor has to be bang on as 600x600 can be a nightmare unless the floor is totally flat, as for the concrete, it depends how much higher it is, will the height be lost once levelled??

I prefer Hardie or similar rather than ply but in this instance I'd level first then Ditra. Ditra should be directly under the tiles to benefit from its uncoupling properties.

I too would level then Ditra not sure if schluter recommend levelling compound over ditra but I may be wrong as things do change from time to time

Terry if the floor is uneven then using 600x600 tiles will be a nightmare!the floor needs to be flat!so screed the floor flat with fibreplan and tile it. as long as the floor is rigid and stable you will be fine.you don't need ditra!! imho sorry for confusing you

I,ll tell you, 10 years ago i did hallway with 300x300 nero granite tiles straight on ply. after 7 years floor was still solid, not even tiny crack in grout. But now allways use ditra. So it's up to you how you want to do it

Re: 16mtr, 600 by 600 porcelain kitchen floor on ply ? advice please

from a technical standpoint on the photos provided you should:

1. level the entire floor with a good quality SLC (fibre reinforced would be a preference for me!)
2. lay a decoupler across the entire area and then tile........

but because the area is sooooooo small i would lay a simple (inexpensive) crack iso membrane like "maptex" or "mapnet".... then screed with a good quality SLC and tile away...........(maptex is a fibreglass roll and mapnet is like underfloor heating without the wire!)

best wishes

Lee.

I've spoken to Bal and Schluter about this very issue and got two different answers, one said Ditra onto ply then level, the other said level on the ply then then Ditra.
In my opinion why level onto ply and then Ditra, if you need an uncoupling membrane because you are using ply then get the ditra in first.
This one is down to you matey, there are no fixed rules here!!
