do any other tilers do this - Tile Advice

[Mattash99]

Evening all

More a watcher than a poster, but, I priced a job up for 37 metres on the electric matting, which include slc and schlutter, but was told today that the tile supplier can get a tiler that will tile straight on to the wires and without schlutter!! Can't believe anyone would do this over such a big area, wouldn't do it over a metre let alone 37 of large format porcelain

What's the substrate?

What is the substrate ?

 

[hmtiling]

If there's thermal boards and a solid floor, then i'd have no qualms about tiling straight on it

 

[Mattash99]

Part ply part existing screed

 

[J Sid]

two mat zones and expansion joint between them, make sure no movement in ply part and I probably wouldn't ditra

I always use slc over underfloor heating because it easier to do .

yeah, also always slc over electric ufh. I'm not sure if he's asking about slc or ditra thiugh?

To be honest, both. Thought there was a certain tolerance of slc that had to be over the wires

 

[Rookery]

I too always slc over ufh cables on insulation board and wouldn't normally uncouple if fixing porcelain.

 

[Rich Midge]

As above, I use a decoupler with stone not porcelain. I slc enough to cover the wires though some do say a minimum thickness over ufh cables.

On previous conversations I've had with schluter they like at least 3mm between ufh wires and ditra . Dural not so fussed

If i was to use heat mats, which i don't since devi went and killed that bit of the market, i wouldn't usually use a membrane. I see the mat fibres give a softening effect to any lateral stresses. I'd always use slc though. I think fixing direct to cables is crazy, but onto mats you're bound to be leaving loads of air pockets.
I know, i know - it can be done and manufacturers will agree, but i personally wouldn't.

Dural and 'fussed'.
Not often seen in the same sentence!

Getting back to a previous thread air pockets around cable can equal burnt out mat at this point and because of air pockets this is tilers fault for cause of failure according to thermonet. Don't understand why you don't use heat mats please explain wish I didn't have to . Also agree I'm sure there is so added strength due to mesh
