So are you saying direct to screed then? I think it's because of the weight of the vehicles going onto the tiles.

Yeah if there's no ufh don't bother uncoupling as Pete says. The reason I said I would if I were to do my job again was, it was a heated floor and the customer and designer had me use 2mm joints.

So sorry to be a pain but I'm getting slightly confused now. Can I confirm that I am OK to just tile straight onto the SLC that is on top of sand and cement screed? The floor has no underfloor heating? It's just the weight of the cars that are a problem?
That's fine to tile direct. I've tiled loads of car showrooms on both new and old screeds and never decoupled.

Ahh cheers for that I didn't read Bri's post properly! So it's just the heat when the membrane is required! So I quite alright to tile the porcelain onto the screed. The guy I'm doing it for bought the same tiles that a local car garage used for there show room, so they should be fine.

How long has the screed been down?

Not 100% but I would say about 2 weeks. I can find out though.

Make sure that is fully cured before tiling. You can tile earlier by using either a green screed adhesive or a decoupler as a moisture barrier.

Hoe long for screed to fully cure usually? Not clued up on this?
