Hi all, the last few year I have spent tiling in Spain so have lost touch with materials available in the UK.
I have 20m2 of 20mm 1.2 x .600 Marble to lay over electricUFH , which addy, clip spacers and sealer can you recomend that is available also do you self level on top of the UFH or tile straight on top, thanks in advance.

Assuming it’s on a solid cured substrate (if not then give more details) you’ll need to level over the eufh to fully encapsulate the wires to prevent burn out from a void and also to protect the wires. Then you’ll need an uncoupling membrane and I’d go with a slow set C2S1 white tile adhesive. As for brands there are many and it might depend on what you can get locally. Any major brand will be able to supply you with everything under the one roof so which is better to do for the warranty.
Isomat, BAL, Tilemaster or Python are just a few of the brands you should look at.

Nice one,its a solid screed been down 30 years so no probs there, havent seen the spec for the UFH but I assume insulating boards will be needed? Is the uncoupling necessary as the client is really OCD over the height he is even taking thermo plastic tiles up to save 3mm though probably better gone.

It’s a must with Natural stone and ufh.

What is the reasoning behind it so I can explain to the customer, I assume expansion.

 

[Andy Allen]

expansion will cause the soft stone to crack, a decoupling mat is a must not an option.

Don't mind me while I bump up some older but good threads. If you can contribute to the thread, go ahead. But if it's nothing for you then don't reply and it'll soon drop off the What's New page etc.
