Hi Peeps
Looking at a floor this week with wet underfloor heating.
So the customer has said the heatings run to temp. Slab put down in January. Likley be end of may for tiling. Not tiled over wet underfloor heating before so want to make sure the preps right.

Any tips/advice much appreciated.
Cheers

What type of floor is it, sand and cement?

I asked the home owner and it’s 4in cement then 4in kingspan then 60mm screed. He says it was a normal dry mix screed. I've got the name of the screed company, local so can check that with them.

Get all the details off the screed company, and also make sure the ufh has been commissioned

Would you use ditra for the expantion in the screed @Adey1980 ??

Porcelain tiles? Providing it’s been commissioned and it’s not cracked badly then I wouldn’t fit an uncoupling mat.

Would you not be worried about the expansion when it heats the base up? Not sure on tile choice yet, not going until Friday to look at it.

As @Localtiler said but if you want to offer belts and braces and customer is willing to pay for it

I find it just confuses things, I either say it needs it or it doesn’t need it and stick to it! Certainly better with it but I don’t see it is an essential
