120m2 Garage Floor Tiling Price Check

Why decouple if there's no UFH?

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?

A decoupler is to protect against lateral movement, the screed expanding and contracting as it heats and cools, it wont make any difference with regards to the weight being applied from vehicles

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?
