Natural Stone Floor with UFH

[jimmi-c]

Hi peeps, So I've got this kitchen floor to price up, about 15m2 of natural stone going onto a nice flat screed also got to fit the UFH matts

I've not done a great deal of UFH work so I'll need some advice on this 1

Can i fit the UFH direct onto the screed or do i use ditramat? or backerboards? What do you think is the best method?

Also the customer has asked me about 'non-slip' sealer?? does such a thing exsist? I never heard of it

Any advice much appriciated! Cheers guys:8:

are you fitting insulation?

i would go with insulation boards, then slc over ufh, you could use a decoupling membrane

yea i think its a good idea cos otherwise the heat from the UFH will be lost thru the screed?

ok cool, so we're talking insulation boards fixed to the screed with adhesive? then the heating matts, then some SLC to cover the matts, then ready for tiling?

Natural stone needs to be sealed anyway, I would advise against using another type that says its non slip, mixing sealers is not recommended.
